A NOTE TO YOU

Thank you for buying our Waterco Heat Pump Pool Heater
A heat pump pool heater is a highly efficient, cost effective method of pool heating. Intelligent
operation and care will result in many years of enjoyment and pleasure. Please note that
this handbook is a complement to the general user handbook, therefore this does not
replace it.
SubZero (Technical Features)
Our Waterco SubZero Heatpump was specifically developed to heat water through the use
of ambient air to a temperature lower than standard models. The defrost is carried out by
reversing the refrigeration circuit, thereby injecting hot refrigerant into the evaporator. It is
possible to quickly defrost the evaporator even when the temperature in the air is closed to
freezing point. This defrost cycle is not possible with standard machine since it is only carried
out by ventilation system.
It is strongly recommended to install a solar blanket on the swimming pool when the
temperature of the ambiant air is between 0 and 12 degres Celcius in order to limit heat loss
through evaporation. It is very important to understand that when there is a huge difference in
temperature between heated water in the swimming pool (high/hot) and the air temperature
(low/cold), heated water in the swimming pool will cool quickly.
In some case, if you don't put a solar blanket when the ambiant air is very cold, the evaporation
will be equal to the input of heat from the heatpump. Therefore, the temperature of the water
will not rise.
