INTRODUCTION
Congratulations on the purchase of an Astral Pool Heat Pump, Pool and Spa Heater. Proper installation
and service of your new heating system and correct chemical maintenance of the water will ensure many
years of service. It is equipped with features that take advantage of new technology developed
exclusively by Astral Pool.
This unit can safely be connected to PVC pipe. In addition, the unit is equipped with an accurate
electronic thermostat to ensure ease of use and accurate temperature control. The electronic display tells
at a glance the operational status of the heater.
Your heat pump works by extracting heat from the surrounding air. The heat pump works most
efficiently in warm weather. So, it is best to operate the heat pump during the warmest part of the day
rather than overnight or early in the morning.
It is important to ensure an adequate supply of air and to avoid recirculation of the cooled air exiting the
top of the unit. For this reason, the heat pump should not be installed in confined spaces and must have a
minimum of 1000 mm clearance above it and 500 mm clearance to the sides and rear. A clearance of
1000mm is required to the front of the unit to allow air flow out of the unit.
Although the unit is weatherproof, it is recommended some protection from the harsh effects of direct
exposure to the elements be provided.
The heat pump must be installed outdoors on a level concrete pad.
In most circumstances where heating is required, the heat pump will need to run longer than the filtration.
For the most effective heating it may be necessary to install a small pump to circulate water through the
heat pump independent of the filtration system. Since the heat pump uses electricity so efficiently, it is a
pity to waste electricity running an oversized pump. For this reason, the small added cost of a dedicated
pump can be recouped and a great deal of energy saved over the life of the heater.
