3513.3 CLEANING OF THE CIRCUITWARNING! In the case of engine burning,with perforation of the windings, it is necessarythoroughly clean the refrigeration circuit to avoidsubsequent burns or breakdowns.The purpose of cleaning is to eliminateall carbon or other solid state deposits e,according to the method used, they must beeliminated vall the contaminants that have beenintroduced for the circuit cleaning or by effectof the operations carried out.WARNING! Do not inhale refrigerant vapourscoming from burned compressors, as it canbe in the presence of toxic products. Avoidaltogether contact with the skin of residualcompressor oil burned, as it is generally acidic.13.4 REFRIGERANT CHARGEWARNING! For no reason the refrigerant gasin the liquid state it must be charged on the suctionsideon the compressor as this condition involvesdamage to the compressor.The operations to be performed are the following:- connect the cylinder (or charging cylinder) to theSAE 1/4 pipe system and connectionsswivel female at the pressure point in theliquid side of the air / refrigerant gas heatexchangers;- insert refrigerant in the liquid state:a) until the required charge is reached;b) until the balance is achievedpressures between cylinder and refrigerant circuit;- start the appliance and, if necessary,insert the remaining refrigerant untilachievement of the prescribed values.The charge tuning operation goesmade using the suction socket of thecompressor, inserting the refrigerant to the stateliquid gradually;- check the refrigerant charge.WARNING! Make sure the tools usedare in good condition and suitably ta13.5 VERIFICATION OF OVERHEATING- read the temperature value in the pressure gauge,in correspondence of the detected pressure value.The temperature read by the thermometer must begreater than the temperature read on the gauge of avalue between 3 ° C and 8 ° C for operationin cooling mode, between 1 ° C and 5 ° C foroperationin heating mode.14. CLOCK INSTRUCTIONSWEEKLY PROGRAMMER14.1 DESCRIPTIONThe programmer is equipped inside with arechargeable lithium battery that allows you tosave time and schedule for about 5 years,even without mains power supply. During thenormal operation, the display shows the dayof the week and the current time, in addition to thestatus ofoperation in which the presence of the symbol of alight bulb indicates that the appliance is switched on.14.2 OPERATING INSTRUCTIONSThe functions of the keys, with reference to fig. 9, arethe following:1) Time setting:Press the clock symbol at the same time assymbol D +, to adjust the day of the week.To set the time, press the clock buttonsimultaneously with H +.To set the minute, press clocksimultaneously with M +.2) Gear / programming switch: Pressthe "MANUAL" button to switch between theposition "ON" "AUTO" and "OFF".3) Key "P" for selecting the programs ofPower on / off.4) "H +" button for progress and time selection.5) "M +" button for advancement and selection ofminutes.6) Key "D +" of progress and selection of daysWeekly.7) Tasto Key to change the time and day ofweek and to return to the current time when you arein "PROGRAMMING" mode.14.3 SETTING THE DAY AND THE CURRENTTIMETo allow the correct operation of the programmermust set day and time currents acting as follows:- start the appliance;- insert into the pressure outlet, positioned in thelarge tube near the compressor,the low pressure gauge for the measurement of thepressure;- wait for the values to stabilize for around 20minutes;- measure the temperature value on the pipelarge (steam phase), near thepressure connection using a special onecontact probe; |
