R407C is a zeotropic refrigerant mixture which has Zero Ozone Depletion Potential (ODP = 0) and thus conformed to the Montreal Protocol regulation.
- Page 73 b) 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. c) 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 76 (B) Outdoor Unit As condensing temperature rises, evaporating temperature rises and cooling capacity drops. In order to achieve maximum cooling capacity, the location selected for outdoor unit should fulfill the following requirements : • Install the condensing (outdoor) unit in away such that hot air distributed by the outdoor condensing unit cannot be drawn in again (as in the case of short circuit of hot discharge air).
- Page 77 Condensed Water Disposal Of Outdoor Unit (Heatpmp Unit Only) • There are 2 holes on the base of outdoor unit for condensed water to flow out. Insert the drain elbow to one of the holes. • To install the drain elbow, first insert one portion of the hook to the base (portion A), then pull the drain elbow in the direction shown by the arrow while inserting the other portion to the base.

- Page 90 Special Function Special Function Special Function Special Function 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 91 c) Hot spurt During cold start, the set temperature of controller is increased by 2 C to stabilize the room temperature ° quickly. After the first stop of compressor or 30 minutes following the start of operation, the temperature setting will be restored to the original value.
- Page 92 (D) Overload Protection In Cooling Operation When outdoor and indoor air temperature raise beyond the operation limit, or when the outdoor coil choked with dirt, the M.C. controller detects abnormal increase in condensing temperature. It will stop the operation to prevent compressor burn out. (E) Frost Prevention And Filter Check In order to prevent the freezing of indoor coil, the controller will operate as follow.
