All Enviromax 10 heat pumps built in Sept. 2006 and later, include a number of changes to ensure more reliable operation. The date of manufacture of the Enviromax heat pump is contained in the serial number. The last two digits of the serial number are the date code; the first digit indicates... -
Page 5: High Pressure Switch
The loss of charge switch is located on the liquid line. It opens at 35 PSIG and closes at 60 PSIG. This switch protects the Enviromax Heat Pump if there is a loss of refrigerant. See "Lockout" section below for a complete description of the operation of the loss of charge switch. - Page 6 VAC POWER HAS BEEN APPLIED CONSTANT ON NORMAL OPERATION HIGH PRESSURE SWITCH HAS OPENED 1 BLINK STATUS TWICE LOW PRESSURE SWITCH HAS OPENED BLINKS TWICE POST PURGE DELAY ON MAKE WHEEL (COMPRESSOR TIME DELAY) WHEEL LEDs Enviromax, 1/06...

Page 8: General Operation
1.3 General Operation Refrigerant Cycle (Cooling Mode) The Enviromax™ HP uses R-407C refrigerant in a conventional vapor-compression refrigeration cycle to transfer heat from air in an enclosed space to the outside. A blower assembly blows indoor air across the evaporator. Liquid refrigerant passing through the evaporator is boiled into gas by heat removed from the air. -

Page 11: Installation
1. Noise. Install the unit so that the least amount of noise will be transmitted to inhabited spaces. 2. Condensate Drainage. The Enviromax heat pump can produce over 4 litres per hour of condensate during normal operation. This condensate must be disposed of to a suitable loca- tion. -
Page 12: Minimum Airflow Requirements
Enviromax 10 heat pump. If the power supply is 225 volts or less, the toggle switch to the left of the thermostat on the side of the unit must be placed in the DOWN position. -
Page 13: Condensate
The condensate produced during the cooling operation and water produced during the defrost cycle must be disposed of to a suitable location. To dispose of the water, a pump is factory installed in the Enviromax heat pump. The water pump is located beneath the outdoor coil in a sump. Water produced during the defrost cycle collects in the lower pan and flows into the sump. Condensate from the upper pan flows directly into the sump. When the float switch in the pump closes, water... -
