3 FOREWORD This manual has been specially prepared to give guidance in the use and maintenance of the: Horizontal Laminar Flow Workstation Model Numbers The manual contains all the facts and information to ensure the best and most trouble-free operation of the equipment, along with advice on first-line maintenance so as to keep them in good working order. Service and maintenance operations other than those covered by this manual should only be undertaken by BIOQUELL's recommended service agent, BIOQUELL Service or by other approved agents. Caution: Important Handling Information DO NOT lift the Horizontal Laminar Flow Workstation by any part of the work surface, particularly the front edge. The unit should only be lifted by the ends and the back. When lifting the unit with a forklift, support such as a pallet is required. If a stand is supplied with the unit, instructions on how to build it is given in Appendix 4 Figure 1 Horizontal Laminar Flow Workstation - Model Page 3 of 24

4 1 INTRODUCTION The range of BIOQUELL Horizontal Laminar Flow Workstations have been designed specifically to be extremely compact, efficient and reliable (model numbers are [Fig. 1], 50546, 50547, and 50549). The units provide a clean environment ideal for the Medical, Pharmaceutical, Electrical, Food and Industrial fields for sterile manipulations, miniature mechanisms assembly and production of optical preparations, in fact any applications requiring clean conditions to protect the product from airborne contaminants. To achieve these conditions the unit operates by drawing air from the room via a pre-filter mounted on top of the unit. This filter takes out the large particles to preserve the life of the main HEPA filter. A fan mounted directly below the pre-filter draws the air into a plenum at the rear of the cabinet, behind the main filter. The pressure created in the plenum forces the air through the main filter to give horizontal laminar air flow over the working area to conform to DIN24184 Class S, American Federal Standards 209D Class 100, British Standard BS 5295 Class F and BS EN ISO Class 5. A schematic of the airflow is shown in figure 2. To assist in the economical maintenance of the unit, the filters are easily accessible for servicing, and the maintenance free fan system ensures a low noise level for operator comfort.

5 2 SPECIFICATION 2.1 CONSTRUCTION The outer shell and canopy is fabricated in mild steel finished in white enamel. The work surface is manufactured in stainless steel Grade 316. Special attention has been paid in the design and construction to avoid crevices. The side screens are clear toughened glass. At the bottom of each side screen is a service panel section which is fitted with two internal 13 Amp electrical sockets, one either side. Optional extra Service Connections, i.e. taps to transfer the supply from outside, to the working area can be fitted if required. 2.2 ELECTRICAL 230 Volt 50 Hz Single phase supply. Other voltages are available to order. The power supply to the unit is through a detachable independent electrical connection (IEC) cord, fitted with a plug and socket at either end. The connecting plug on the unit is fused at 10 Amps on both live and neutral lines. The unit has two (Supplied as standard) internally wired 13 Amp type sockets, one either side. Although the socket rating is labelled 300 Watts maximum on each socket, it is permissible for this to be increased as required on one socket, subject to the combined consumption of the two sockets not exceeding 5 Amps. 2.3 POWER CONSUMPTION/ POWER SUPPLY The power supply to the unit should be protected by a current operated earth leakage trip. The power consumption for each model is as follows: Model No Amps Amps Amps Amps Amps 2.4 LIGHTING Fluorescent lighting is mounted behind the opal diffuser in the canopy. The lighting level is in the region of 1,000 LUX. Page 5 of 24

BIOQUELL OR ITS AGENTS CANNOT ACCEPT RESPONSIBILITY FOR DAMAGE, LOSS OR INJURY CAUSED BY, OR RESULTING FROM, INCORRECTLY INSTALLED EQUIPMENT Important BIOQUELL or their appointed agents and distributors will only consider themselves responsible for the safety, reliability and performance of the installation if: (a) (b) (c) Extension, modification, relocation or repairs are only carried out by authorised personnel. The electrical installations in the room concerned comply with national regulations. The equipment is used in compliance with these operating instructions and only by trained personnel. The units are supplied ready assembled and only require connecting to services if fitted: a mains socket, gas, vacuum, and the assembly of the stand (option). The plug is fitted with a 5 Amp fuse. Stand installation instructions are in Appendix 4. WARNING: THIS APPLIANCE MUST BE EARTHED. Page 7 of 24

8 2.9.2 Commissioning Installation is normally carried out by BIOQUELL engineers. If installed by others, BIOQUELL should be called to check and commission the unit before use. Page 8 of 24

9 3 OPTIONAL EXTRAS 3.1 BASE ASSEMBLY For application where bench space is not available for the workstation, a tubular steel base assembly is available to make the workstation free standing. The base assembly is finished in white enamel and is fitted with either adjustable feet, or castors. 3.2 SERVICE CONNECTIONS Services such as gas, compressed air, vacuum etc. can be fitted via the service panel section. The connections are laboratory taps, having barbed hose connections on each side. 3.3 ULTRA VIOLET LIGHTING An ultra violet light may be fitted if required for experimental work but this should not be used as a sole means of cleansing, or decontaminating the workstation. When fitted, the bactericidal ultra violet output should be tested frequently, since after a limited time of operation the germicidal properties may disappear even though the visible rays remain unchanged. If a UV light is fitted, a front closing panel should be used for safety. 3.4 FRONT CLOSING PANEL In order to avoid particulate contamination entering the work area whilst the unit is not in use, a front closing panel may be fitted. This is not completely gas-tight and therefore it will not stop every particle, but it reduces the purging time required for the unit prior to use by about 50 to 75%, (Note: Panel must be removed before switching on the unit). 3.5 FIREBOY GAS BURNER This burner has been specially designed for use in safety cabinets and laminar flow units. It can be supplied with a foot-operated switch, if required, which operates a solenoid valve allowing the gas to flow and gives instantaneous ignition. The burner can either be set for a fixed time of operation, or can be extinguished by operation of the foot control a second time. The advantage of this type of burner is that the flame is only there when actually needed causing minimum disturbance to the airflow pattern within the unit. Page 9 of 24

10 4 OPERATING INSTRUCTIONS All BIOQUELL Horizontal Laminar Flow Workstations are fitted with on/off switches for the fan, fluorescent lighting and where fitted, the ultra violet light (see Figure 4). Where fitted, care should be taken to ensure that the operators are aware that the ultra violet light is in use and a front closing panel should be fitted. Connection to the mains is via an IEC cord, fitted with plug and socket. When a bank of units are installed, they should all preferably be connected to an individually fused supply. After connection, switch on the unit and ensure that the fans are running freely and that all other functions are operating correctly. The air flow velocity has been factory set and tested and should not need further adjustment, however to ensure that no change has occurred during transit, the airflow should be checked with a rotating vane anemometer. If any adjustment should be required, the procedure is given in the maintenance section of this manual. After wiping down the working area, allow the unit to run for minutes to purge the working area before commencing work. Whenever the unit is switched off it must again be purged. If a front panel has been used during this off period, the purging period may be reduced to approximately 10 minutes. Figure 4 Standard Switch Panel Complete with Airflow Diagram Page 10 of 24

11 5 MAINTENANCE 5.1 GENERAL The range of BIOQUELL Horizontal Laminar Flow Workstations have been designed to give many years of trouble-free, efficient service, to keep maintenance to a minimum and to ensure that the maintenance which is required is straightforward. A full maintenance service is provided within the United Kingdom by BIOQUELL Service. Under this contract both preventative and corrective maintenance are carried out. Overseas this same service is offered by the BIOQUELL distributors. In addition to this, operators should carry out procedures to ensure that the unit is kept in first class working order. 1 The unit should be kept clean externally and the work area must be regularly cleaned. Wiping over with a damp swab using a proprietary bactericidal solution should be adequate. 2 Ensure that the air intake and pre-filter are free of any obstruction that will hinder airflow. 3 Check that the fan, light and switches are all working efficiently and correct any apparent faults. 4 Check the condition of the pre-filter, since the pre-filter directly affects the life of the high efficiency filter, it is important that the pre-filter is kept in good condition. It is readily apparent if it will need changing and the procedure is set out under Pre-filter Servicing. 5 Periodically inspect the mains electric supply cable to the unit for damage, or wear. In the event of any fault with the cable contact the BIOQUELL Service. 5.2 CARE OF THE STAINLESS STEEL WORK SURFACE Refer to Appendix CHECKING AIRFLOW VELOCITY To check airflow velocity, the equipment required is a rotating vane type anemometer with a head diameter of 100 mm. The fans should be switched on for at least 10 minutes prior to carrying out the tests. The anemometer should be placed 150 mm from the filter face, making air velocity measurements over a period of at least 5 minutes for each measurement. Refer to Table 2 for position of each reading. Page 11 of 24

12 The mean of measured airflow velocities shall be between m/s (88 19 ft/min). Should the airflow have fallen below the required level then the speed controller must be adjusted. This is located on the internal right hand side panel below the pre-filter and screen (for removal of pre-filter and screen see Pre-filter Servicing ). The adjustment is carried out by rotating the potentiometer on the control PCB, clockwise to increase airflow velocity, anti-clockwise to decrease airflow velocity. The adjustment is carried out whilst using the anemometer as previously.

Refitting is reversal of above. Page 12 of 24

13 5.5 MAIN FILTER SERVICING The main filter should normally be changed by the BIOQUELL Service Engineer because of the retesting requirements, and rechecking of airflow velocity. Should it for any reason be necessary for this to be carried out by other than a BIOQUELL Service Engineer, the procedure is as follows: 1 Switch off the unit and isolate from the electrical supply. 2 Position the unit so that the rear of the unit is readily accessible 3 Undo the screws holding the rear panel in place and lift away the panel (see Figure 5). 4 Remove the two main clamping angle bars, top and bottom of the filter (see Figure 6) by removing four hexagon (eight on Models and 50549) nuts. Note the position the angle bars are fitted along the filter. 5 The main filter may now be removed from its casing. 6 Before fitting the new filter, examine it carefully for signs of damage to the face, or to the sealing gaskets. 7 Replacement is the reversal of stages 1 to 4. When tightening the clamping angle bar hexagon nuts ensure they are evenly tightened down. 8 Having completed the filter change, the WorkStation must be fully retested to ensure the integrity of the filter and the sealing joints. This is done by using either electronic particle counter, or by using an Aerosol Generator and Photometer. Figure 5 Rear Panel Removal Page 13 of 24

14 Figure 6 Main Filter Clamping System 5.6 FLUORESCENT TUBE REPLACEMENT (see Figure 7) Should any of the lighting tubes in the unit need replacing, the procedure is as follows: 1 Switch off and isolate the unit from the electrical supply. 2 Remove the pre-filter and their screens (See pre-filter servicing). 3 Remove the plugs from each end of the tube to be replaced. 4 Remove both tubes from the supporting clips holding the tubes in position. 5 Unscrew the nuts securing the lights support brackets and remove the brackets from the unit. Rotate the tube around the fan and lift out of the unit at one end. 6 Refitting is a reversal of the above. Access to ballast s and starters is achieved by removing the pre-filter and their screens. They are located internally on the right-hand panel. Page 14 of 24

19 APPENDIX 3 - CARE AND CLEANING 1 STAINLESS STEEL COMPONENTS Considerable care has been taken in the selection and processing of the stainless steel components used in the construction of this equipment, however even stainless steel can be damaged by chemical attack. It is therefore important to ensure that any cleaning or disinfecting procedures used will not cause a chemical attack that may damage the surface of the stainless steel. Work surfaces should be kept clean and free of chemical liquids, particularly those containing Chlorine. Liquids or vapours containing Chlorine are known to cause gradual staining of stainless steel. To avoid this, when chemicals are used containing Chlorine all surfaces should be thoroughly dried and all traces of the solution removed, the area should then be treated with a neutralising agent. Open vessels left inside the equipment which are likely to cause Chlorine vapours may also result in staining of the metal surfaces. Should the surface of the stainless steel become stained, it may be cleaned by mechanical polishing and special treatment of the affected area. Our service department can help with this process. 2 PLASTIC COMPONENTS Cleaning of the plastic items should only be carried out with mild detergent or chlorine based cleaning solutions. Care must be taken not to apply chlorine solutions to any stainless steel metalwork, as this will potentially cause staining. Do not apply heat, abrasive materials, solvents or solvent wipes to the surface as this can cause irreparable damage. Page 19 of 24

20 APPENDIX 4 ASSEMBLY INSTRUCTIONS FOR STAND The following will arrive in the box A left and right hand stand 4 off Cross members 4 off Stand bars (in a packet) 4 off stand bases 8 off Bolts and washers 4 off Nuts ASSEMBLY PROCEDURE Fit all four feet by screwing the nuts onto the stand bars, and then screwing the bar into the bottom of the left hand and right hand stand. Screw the bar in the same amount and lock off with the nut. Then push the black base onto the stand bar. Page 20 of 24

21 Fit two cross members using the bolts and washers, the washer goes under the bolt head. Ensure the left and right stand are oriented the same, with the long foot at the front. Fit the top cross members with the remaining bolts and washers The stand ought to now look as shown. The Front is shown in the photograph on the left hand side, with the long foot. Place the stand in the required position, and adjust the feet to take-up any irregularities in the floor, so the stand is stable Page 21 of 24

22 The stand height can be adjusted to that required between 730 and 980mm from the ground. To adjust the height, remove the screw on one side of the stand leg and pull the screw out from the other side. This will remove a bar which holds the two parts of legs. Once all four bars have been removed the top part of the stand can be moved vertically to the required height. Then replace the bars ensuring the internal holes line up with the external hole. Secure by replacing the screw on the other side of the bar. Page 22 of 24
