Start Up
1. Verify that the Power LED is ON and that the pool pump is running and circulating
properly.
2. Verify that the control panel Spa-Remote-Pool switch is in the Remote (OFF) position;
See figure on page 7.
3. Turn the control switch to either Pool or Spa to turn the system ON and raise the
appropriate temperature dial above the current water temperature. At this time the two
green LED’s (water flow and heat demand LED’s) should illuminate. The fan and
compressor should start up and run (Note: The compressor has a six minute time
delay).
4. Allow the Heat Pump to operate for a few minutes to stabilise operating pressures and
to allow various component temperatures to normalise.
5. Verify that the discharge air temperature is approximately 4ºC - 6ºC cooler than the air
entering the unit.

Refrigeration Terms and their Meaning
Sub Cooled Liquid – A substance below its saturation temperature at a given pressure.
Super Heated Vapour – A substance above its boiling point at a given pressure.
Saturated Vapour – A substance at its boiling point at a given pressure.
Latent Heat – Hidden (invisible) heat removed or added to a substance that results in a
change of state (i.e. liquid to a vapour) without an increase or decrease in temperature.
Heat of Compression – The additional heat added to a substance by the act of
compressing it.
Low Side – Components and pipe work of a refrigeration system operating at low
pressure, generally considered to be the evaporator, suction line and accumulator.
High Side – Components and pipe work of a refrigeration system operating at high
pressure, generally considered to be the condenser, discharge line, liquid receiver/filter
drier and compressor case where a rotary compressor is utilized.
