13 TESTING THE ELECTRONIC CONTROL BOARDS FOR XQ MODELS Activating T est Mode: Activate test mode by pressing at the same time the “MODE” button and the “TEMP ” button on XQ models . LEDs for Hour , Start, and Stop will blink 1 bps while T est Mode is active.
TEST : 1 . Remov e leads from ther mostat . 2. Tu r n t h e r m o s t a t k n o b c l o c k w i s e t o i t s c o l d e s t position. 3. T est for continuity between t he t wo terminals. Contacts should be clos ed. 4. T urn thermost at knob counterclo ck wise to its warmest position.
CAP ACIT ORS ELECTRIC SHOCK HAZARD W ARNING T urn off electric power before servicing. Discharge capacitor with a 20,000 Ohm 2 W att resistor before handling. Failure to do so may result in personal injury , or death. Many motor capacitors are internally fused.
HEA TING ELEMENT (See Figure) All elect ric heat mod els are equi ppe d with a heat ing e lem ent . The EQ08 has a 1.15 KW element. The heating element contains a fuse link and a heater limit switch.
Suction Line Evaporator Coil Metering Device Refrigerant Strainer Discharge Line Condenser Coil Compressor Refrigerant Drier Liquid Line A good understanding of the basic operation of the refrigeration system is essential for the service technician.
• R-410A pressure is approximately 60% higher than R-22 pressure. • R-410A cylinders must not be allowed to exceed 125 F , they may leak or rupture.
Proper refrigerant charge is essential to proper unit operation. Operating a unit with an improper refrigerant charge will result in reduced performance (capacity) and/or effi ciency . Accordingly , the use of proper charging methods during servicing will insure that the unit is functioning as designed and that its compressor will not be damaged.
3. Install a process tube to sealed system. 4. Make necessary repairs to system. 5. Evacuate system to 200 microns or less. 6. Weigh in refrigerant with the property quantity of R410-A refrigerant. 7. Start unit, and verify performance. 8. Crimp the process tube and solder the end shut.
Underchar ged R efrigerant Systems An undercharged system will result in poor performance (low pressures, etc.) in both the heating and cooling cycle. Whenever you service a unit with an undercharge of refrigerant, always suspect a leak. The leak must be repaired before charging the unit.
R estricted R efrigerant System T roubleshooting a restricted refrigerant system can be diffi cult. The following procedures are the more common problems and solutions to these problems. There are two types of refrigerant restrictions: Partial restrictions and complete restrictions.
Lock ed Rotor V oltage (L.R.V .) T est Locked rotor voltage (L.R.V .) is the actual voltage available at the compressor under a stalled condition. Single Phase Connections Disconnect power from unit.
Single Phase Resistance T est Remove the leads from the compressor terminals and set the ohmmeter on the lowest scale (R x 1). T ouch the leads of the ohmmeter from terminals common to start (“C” to “S”). Next, touch the leads of the ohmmeter from terminals common to run (“C” to “R”).
R ecommended procedure for compr essor replacement 1. Be certain to perform all necessary electrical and refrigeration tests to be sure the compressor is actually defective before replacing. 2. Recover all refrigerant from the system though the process tubes.

R OUTINE MAINTENANCE AIR FIL TER Clean the unit air intake fi lter at least every 300 to 350 hours of operation. Clean the fi lters with a mild detergent in warm water and allow to dry thoroughly before reinstalling.
SLEEVE / DRAIN Inspect the sleeve and drain system periodically (at least yearly or bi-yearly) and clean of all obstructions and debris. Clean both areas with an antibacterial and antifungal cleaner . Rinse both items thoroughly with water and ensure that the drain outlets are operating correctly .
29 29 Due to variations in room design, climate zone and occupancy , larger areas may require the use of multiple units to provide the optimal cooling solution. This is a general guide. Please consult manual J or M for exact load calculations. 1. If heavily shaded, reduce capacity 10%.
Problem Possible Cause Possible Solution Unit does not operate. The unit is turned to the off position, T urn the unit to the on position and raise or lower temperature setting (as appropriate) to call for operation. The LCDI power cord is unplugged. Plug into a properly grounded 3 prong receptacle.
Unit Does Not Cool/Heat On And Off T oo Frequently (continued). The outside temperature is below 60° F (16° C). Do not try to operate your air conditioner in the cooling mode when the outside temperature is below 60° F (16° C). The unit will not cool properly , and the unit may be damaged.
