    6. SPECIAL PRECAUTIONS FOR R407C SPECIAL PRECAUTIONS WHEN DEALING WITH REFRIGERANT R407C UNIT What is new refrigerant R407C? R407C is a zeotropic refrigerant mixture which has Zero Ozone Depletion Potential (ODP = 0) and thus conformed to the Montreal Protocol regulation. It requires Polyol-ester oil (POE) oil for its compressor's lubricant.
  • Page 21 Ensure that the compressor is not expose to open air for more than the recommended time specified by its manufacturer (typically less than 10 minutes). Removed the seal-plugs only when the compressor is about to be brazed. The system should be thoroughly vacuumed to 1.0 Pa (-700mmHg) or lower. This vacuuming level is more stringent than R22 system so as to ensure no incompressible gas and moisture in the system.

  • Page 34: Special Function

    9. SPECIAL FUNCTION (A) 3 HOT SYSTEM (Heating cycle) a) Hot start At the beginning of heating operation (cold start, after defrosting or thermostat resumes operation) the indoor fan operation is controlled in accordance with the temperature of the indoor heat exchanger to send warm air from the start.
  • Page 35 (B) COLD BLAST (Cooling cycle) During cold start, the set temperature of controller is decreased by 2°C to stabilize the room temperature quickly. (C) OVERLOAD PREVENTION IN HEATING OPERATION During heating operation, if the room temperature and outdoor temperature are high, or when the indoor air filter is choked, the condensing pressure will increase rapidly.

    10. SERVICING AND MAINTENANCE CAUTION: After installing or servicing the unit, please ensure that the front panel is secured by the 1 hook underneath the front panel. The unit is designed to give a long life operation with minimum maintenance required. However, it should be regularly checked and the following items should be given due attention.

  • Page 37: After Extended Shutdown

    PRE-START UP MAINTENANCE (AFTER EXTENDED SHUTDOWN) Inspect thoroughly and clean indoor and outdoor units. Clean or replace air filters. Clean condensate drain line. Clean clogged indoor and outdoor coils. Check fan imbalance before operation. Tighten all wiring connections and panels. Check for refrigerant leakage.
