• Topaz PWC1211, 2. (CAUSE) Thermostat (REMEDY) Examine the control unit for loose wires. Tighten any loose connections. Wait 4-minutes before re-start. 3. (REASON) High Pressure Control cutting turning unit off (FIXING) Check for loose wire connections, broken or burned contacts. If switch is defective, replace. Not enough water flow to unit or water is too warm. 4. (CAUSE) Compressor contactor open or burned. (CURE) Replace 5. (REASON) Refrigerant leak no freon. (REMEDY) Locate leak and repair.

• Topaz PWC1211, PROBLEM: WATER LEAKING FROM PAN 1. (CAUSE) Leaky drain pan (REMEDY) Locate leak and repair pan. 2. (CAUSE) Loose evaporator, drain or condensate pump hose (REMEDY) Tighten connections. 3. (CAUSE) Defective condensate pump or excessive lift on pump (REMEDY) Examine to see if elevation exceeds 20 ft. (if it does, a larger pump will be required). Otherwise, change pump if defective. Pump will operate properly against 20 ft. of water total head pressure on pump. If combination of vertical height and horizontal drain line exceeds 20 ft. of water pressure drop, problems will occur.

• Topaz PWC1211, 2. FILTER A clogged filter will cause the unit to operate at greatly reduced efficiencies. We recommend that the filter be inspected on a regular bases every six weeks or more often depending on the environment. The foam filter is located behind the return air grille and can be easily removed by pulling the grille out. The filter must be washed periodically as needed by placing it in a dishwasher or soaking it in a solution of warm water and detergent for 10 minutes. Then rinsing it clean with hot water and shaking excess moisture from filter. 3. CONDENSATE PUMP When servicing pump follow these steps; 1. M
