Pushbutton 4 = Cooling On/Off - Heating On/Off (if pressed and held, sets to Stand-By). Pushbutton 5 = Automatic water inlet filling disable On/Off Pushbutton 6 = Pump On/Off (litre counter control). 4.2 Self-test on start-up and microprocessor reset When the machine is switched on, all leds light up simultaneously on display. If the electronic card self-test is successful, a beep is activated for 5 followed by illumination of all leds. If a pushbutton is pressed during the self-test, an alarm is tripped. The self-test cycle can be repeated by turning the machine off and then on again. Press and hold down push-buttons and and then press, to display the text RES which resets the microprocessor, clears the memory and sets the default parameters. 4.3 Set-point (water temperature value entry). Press for 3 to show the factory setting of the set-point value, which flashes on display. The set-point value can be increased or decreased as required using the keys or and confirming the new water temperature setting by pressing. The machine is fitted with a differential between compressor start-up and shutdown: E.g. : set +10 C, diff. 2 C. The compressor is activated at +12 C and shut down at +10 C; The resistance is activated at +8 C and shut off at +10 C in heating mode. 9

10 GB 5. OPERATION 5.1 Description and general operating principles RAPIDMAC 50 is a water chiller equipped with a 50-litre tank with an immersed coil conveying the refrigerant (as well as a heating resistance). - control of the water temperature is by means of a sensor. Normally the display shows the water temperature. - Control of the maximum water level is by means of floats with on/off output. - A pump is available (optional) for rapid water drainage. - A pressure relief (safety) valve with on/off output is fitted - An internal litre counter (optional) is available (on manual version only) 5.2 Stand-by function, compressor/resistance management. When the machine is switched on (power delivered to card) after the self-test, the card sets to the status previously applied before power was shut off. Press key 4 to set the machine to cooling mode: the relative led 4 illuminates (green). (N.B. the compressor is started up after the set delay. During this interval led 4 flashes). - the display shows the temperature read by the water sensor - The water inlet solenoid valve is energised, if necessary, until the max. water level is reached. - Led 5 illuminates to indicate activation of the automatic filling cycle. - Once the max. water level is reached, the compressor, if the water temperature is above the set value, starts up. - The compressor shuts down when the set value is reached. - In these conditions led 4 remains lit to indicate that compressor operation is controlled by the thermostat. 5.3 Water heating function. Alternatively, if key 4 is pressed twice (double click) the machine sets to heating mode: the relative led 4 illuminates (red). - the display shows the temperature read by the water sensor - The water inlet solenoid valve is energised, if necessary, until the max. water level is reached. - Led 5 illuminates to indicate activation of the automatic filling cycle. - Once the max. water level is reached, the resistance is activated if the water temperature is below the set value. In any event the resistance cannot be activated unless the max. water level is reached. The resistance shuts off when the set value is reached. In these conditions led 4 remains lit to indicate that heater operation is controlled by the thermostat. - In both these operating modes, key 4 causes shutdown of the compressor or resistance and deactivation of led 4. - All the other functions (temp. on display, pump, etc.) remain enabled. If key 4 is pressed and held the machine exits the operating routine and sets to standby status. 10

11 GB I 5.4 Electric power failure In the event of a power failure, either momentary or prolonged, the machine must resume operation from the same conditions in which it stopped: if it was in stand-by phase it resumes this status; if the compressor, heating resistance or filling solenoid valve were in operation, these resume operation. However, this does not apply to the pump: even if in operation prior to the power failure, it remains off when the system is restarted. 5.5 Rapidmac version with pump a0) Pump and litre counter control Pump operation depends on the maximum pump activation time (3 ), after which the pump shuts down and delivery is stopped. If the pump is disabled the relative pushbutton is also disabled. a1) Litre counter disabled, Remote permissive disabled (machine without litre counter, without dispenser and without external dispenser/mixer but with pump): Press key 6 to illuminate the relative led and activate the pump outlet. Press key 6 again to turn off the led and shut down the pump. a2) Litre counter disabled, Remote permissive enabled (machine without litre counter, but with dispenser or external dispenser/mixer and with pump): When pressed once, key displays the number of litres already present in the memory, led 6 flashes (the value can be modified by means of the / keys) When pressed twice key 6 confirms the set value and activates the water outlet. At the end of the count of litres on output (shown on the display) the tank is emptied. 5.6 Rapidmac manual version Litre counter enabled, Remote permissive and pump disabled: (machine with litre counter, but without pump, dispenser or external dispenser/mixer) - In this configuration, if key 6 is pressed the litre counter is set to count the litres delivered: the display shows the value 00 and as soon as the pulses are sent from the litre counter, the count of litres delivered is started and shown on the display. - In any event, in the same configuration, as soon as the pulses are sent from the litre counter, the count of litres delivered is started and shown on the display. If key 6 is pressed this exits the count of the litres delivered. On subsequent delivery the litre counter will start from 00. After 30 seconds in which the litre counter no longer sends pulses, the display returns to the temperature reading. On closure of the remote permissive input for the dispenser/mixer, the pump outlet is activated and the led of key 6 illuminates. a3) Litre counter enabled: (machine with litre counter, but without dispenser or external dispenser/mixer and without pump). 11

13 7. MAINTENANCE AND CLEANING GB IMPORTANT!!! THESE OPERATIONS MUST BE PERFORMED BY A CERTIFIED INSTALLATION TECHNICIAN ONLY The information and instructions given in this section address all persons operating the appliance: the user, the maintenance technician and non-specialised personnel. Ensure that the electrical power to the system has been disconnected before carrying out any cleaning or maintenance work on the appliance. 7.1 BASIC SAFETY REGULATIONS To safely carry out all cleaning and routine maintenance operations, follow these rules. - do not touch the machine with moist or wet hands or feet. - never operate the machine while barefoot. - do not insert screwdrivers, cooking utensils or any other object between the guards and moving parts. - before performing cleaning or routine maintenance operations, disconnect the machine from the power supply at the master switch and by pulling out the plug. - Never pull on the power cable to disconnect the machine from the power supply. Removal of guards and safety devices for the purposes of routine maintenance is strictly prohibited. The manufacturer declines all responsibility for accidents caused by failure to observe the above regulation. 7.2 CLEANING THE CONDENSER 1) Progressive accumulation of dust on the front section of the condenser will gradually reduce efficiency of the cooling circuit. PERFORM THIS OPERATION ONLY AFTER THE APPLIANCE HAS BEEN SHUT DOWN Therefore make frequent inspections of the condenser and clean with a non-metal brush or vacuum cleaner. 2) At least once a year, check for deposits of lime scale on the cooling coil inside the container: this will avoid wasteful energy consumption and cooling output. To remove these deposits, use a solution of water and citric acid. 3) Drain the water from the tank if the machine is not used for prolonged intervals. 4) Periodically clean the water filter cartridge (optional). 5) IMPORTANT The condenser has sharp edges. Use protective gloves when cleaning. 13
