4 SAFETY PRECAUTIONS Installation and maintenance of air conditioning equipment can be dangerous because system is under pressure, has high temperature of some elements and includes electrical components. Only qualified and trained service personnel should install, start up and make maintenance of the air conditioning equipment. During every visit follow the recommendations from the Installation Operation Maintenance manual, what is shown on unit s stickers and take general legal safety precautions. Follow strictly all safety codes. Use safety glasses, work gloves and some other work safety accessory. ATTENTION! Before staring installation, service or maintenance turn off system main power switch to avoid electrical shock. When repairing the unit use only original spare parts and install them properly in the same place where have been located the old parts. Do not install the unit in explosive atmosphere. OPERATING LIMITS COOLING CYCLE TEMPERATURE Indoor air inlet 27ºC, TS 19ºC, TH Water inlet 7ºC Water outlet 12ºC EQUIPMENT RECEPTION 1. Inspect equipment received for damage or missing elements. If units are damaged or shipment is incomplete, file the claim with the transport company, immediately. Max. term 48h. 2. Check if unit nameplate voltage is correct and agrees with local power supply. RIGGING 1. Before moving the unit, be sure that all unit panels are well fixed. 2. Raise and set down the equipment carefully. 3. Always transport the unit to the installation place in its original packaging. INSTALLATION LOCATION 1. Check if construction is able to support the unit s weight. 2. Check if there is enough service space around the unit. 3. Choose a place free of dust and foreign matter. 4. If necessary, install vibration absorbers through the system to avoid noise transmission.

6 UNIT SETTLEMENT Be sure unit is correctly leveled. Be sure that after settlement of the unit indoor drain is working properly. ELECTRICAL CONNECTIONS ATTENTION! Before starting any type of operations put in position off main power switch. The electrical power supply to the unit should agree with data on the nameplate. Unit star-up at incorrect voltage and resulted from it damages are not covered by Hitecsa guarantee. When making electrical connections always use the unit wiring diagram. Unit current supply should be within +-5% of Volts and Amperes indicated on the unit nameplate. Do not operate at any different current from that is shown on the unit s nameplate. The installer has to install the line protection elements according to the local laws. The interconnecting wires have to be in the protection tube or inside the groove channel. WATER DRAIN The indoor drain (of condensate water) has connection 3/4 MPT. Condensate evacuation line diameter should be equal or larger than unit drain connection depending on the lie length and general building configuration. The condensate line should be pitched a minimum 2% for proper water evacuation. When drain line is exposed to air temperatures below 0 grades is necessary to provide thermal insulation or electrical heating wire to avoid water freezing and tube damage. It is convenient to install the trap with proper dimensions. AIR DUCTWORK - Air ducts dimensions are d in function of the air flow and the available external static pressure. - A qualified technician should make the air duct design. - Use air duct of nonflammable material, which in case of fire, will not emit toxic gases. It is advisable to use metal sheet ducts with insulation. - Use flexible elements between the air duct and the unit, to avoid vibrations and noise transmissions.

Before performing service or maintenance operations, turn off the main power switch to avoid personal injury and put lock on power switch to avoid that any person not connected with the maintenance technical can switch on the electrical supply. It is advisable to make maintenance operation periodically according to the use and operation of the installation, as well as, on every change of the season. - Coils: At least once a year, clean condenser coils with water and detergent and dry later with air at a pressure of 600kPa. Never clean the coil with a wire brush. - Fans and motors: Verify the correct rotation of the fan to warn problems with the bearings. - Drainage system: Check if openings in the unit base for rain and defrost water evacuation is not blocked. - Water circuit: Check for leakage, noise and various system elements vibrations. Take temperature and pressure readings and record it on the maintenance form. - Electrical circuit: Make sure that all electrical cables and other elements are properly tightened. Take electricity consumption of each phase of every fan. Verify the starting current. Check the operations of all relays, contactor, etc. - Air filters: Clean air filters after 4 hours of system operation and then periodically according to the maintenance plan. Filters can be cleaned by immersion in warm water with soap, lates washed in clean water and dry.

13 BEFORE START UP - Check if all wires are well tightened. - Check if all panels are firmly secured with screws. - Verify if unit is installed on level. - Verify if there is enough space for service and maintenance. - Check if drain is not blocked. - Verify if air filters are clean and correctly mounted. - Check all grilles, air diffusers, air ducts and flexible connections. - Be sure that the electrical power source agrees with the unit nameplate rating. - Check that every fan rotates properly. START UP - Start up has to be performed by a qualified service person. - Make start-up check list and use similar check up for service and maintenance. Record chilled water inlet and outlet temperatures and pressures, outdoor air temperature, volts and amps of each fan. - Should remind that after 4 hours of system operation is necessary to clean air filters. - Observe at least, 3 cooling cycle operations.
