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.

NOTICE TO INSTALLERS
Heat Pump must be located outdoors with sufficient ventilation as explained on page 10.
This appliance must be installed by an authorized person.
This appliance must be installed in accordance with the installation instructions, the National Wiring
Rules and any other relevant statutory authorities.
Refer to data plate for details of operating voltage and current.
A multi-pole isolating switch must be installed that operates in all live conductors so that it isolates the
entire equipment from the supply.
Phase rotation must be checked on 3 phase units. Incorrect rotation will damage the compressor and void
any warranties.
SAFETY RULES
1. Spa or hot tub water temperature should never exceed 40˚C.
2. Drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness which could
lead to unconsciousness and subsequently result in drowning.
3. Pregnant women beware! Soaking in water above 38˚C can cause foetal damage during the first three
months of pregnancy.
4. Before entering the spa or hot tub, the user should check the water temperature with an accurate
thermometer, spa or hot tub thermostats may be inaccurate by as much as 2˚C.
5. Persons with a medical history of heart disease, circulatory problems, diabetes or blood pressure
problems should obtain their physician’s advice before using spas or hot tubs.
6. Persons taking medications which induce drowsiness, such as tranquillisers, antihistamines or
anticoagulants, should not use spas or hot tubs. If in doubt seek medical advice.
WARNING: Should overheating occur or the heater fail to shut off, turn off the manual isolation switch
to the appliance. Do not use this heater if any part has been under water.
OPERATING INSTRUCTIONS
1. STOP! Read the safety information above.
2. Turn filtration pump or dedicated pump on. The display should indicate flow.
3. Turn on power to the Heat Pump.
4. Set thermostat to desired setting
5. If the water temperature is below the set temperature, the fan will start. The compressor will start
in a few minutes. (Set by the compressor delay timer)
6. If the appliance will not operate, follow instructions 2 to 4 above ensuring the thermostat is set to
a higher temperature than the indicated water temperature. If the appliance still does not operate,
call your service technician.

During operation in weather below about 10 deg, ice may appear on the evaporator coil. An automatic
defrost mode will initiate. During a defrost cycle the compressor will continue to run however the
direction of the gas in the system is reversed so that the evaporator coil is heated. A ‘whoosh’ may be
heard as this occurs. The fan will continue to run in order to melt the accumulated ice. When the
evaporator temperature rises sufficiently to allow continued operation, the compressor will restart in
heating mode.
During this heated defrost mode, there may be visible water vapour in the airstream. This is normal
during cold weather.
CHEMICAL BALANCE
It is imperative that correct chemical balance be maintained in your pool and spa water, otherwise
corrosion of your heater may occur. Corrosion due to chemically imbalanced water or excessive
sanitiser is detectable and will void warranty. Your local pool shop specialist or spa retailer can
advise correct chemical balance. Your water should be checked and maintained regularly by a pool water
professional. As a guide the following parameters may be used.
pH 7.6 to 7.8
Total Alkalinity 80 to 120 ppm
Calcium Hardness 150 ppm
You should test your water chemical balance at least on a weekly basis.
Excessive sanitiser can damage your heater. Chlorine should not exceed 3 ppm and bromine should not
exceed 5 ppm. Salt chlorinators, especially when used on spa pools or indoor or covered pools, can
easily produce excessive chlorine levels which will damage the heater internals.

Over probation time
If you have set the probation time F87, the alarm occurs when the accumulative running
time is over probation time, and the controller can not work.
%How to set the temperature?
Press the key “set” for at least 2 seconds, then enter the state of temperature setting, here the LED
displays the setting temperature, then using “” key or “” key can change the parameter（the
key“”adds 0.1°C, the key“”minuses 0.1°C, press and hold it over 0.5 seconds can add or minus
rapidly）. After setting, press “set” again, then exit the state of parameter setting. (The setting temp
range is limited by the parameters F13 and F14, please refer to the advanced operation). Pressing the key
“M” in the setting process means cancel and exit, but the setting value will not be saved.
%How to read the outdoor temperature?
When displaying current temperature, press “” key, Controller will display defrosting temperature.
Loose “” key, then return to current temperature. Notice that if you press the key and hold it for 5
seconds, the controller will enter or exit the defrosting state forcibly.
%How to look over and adjust the real clock time?
Press the key “Set” to enter the state of displaying time when in the state of displaying temperature. Press
the key “Set” for some time to enter the state of adjusting time, and press the key “Set” to return to the
state of displaying temperature.
In the state of adjusting time, the hour part of the LED flashes, and you can adjust the hour by using the
key “” and “”, then press the key “Set”, and the minute part of the LED flashes, you can also use the
key “” and “” to adjust the value, then press the key “Set” again to exit. Pressing the key “M” in the
adjusting process means giving up and exiting, but the time will not be saved.
%How to heat forcibly?
When displaying current temperature, the temperature is between “setting temperature－temperature
difference” and “setting temperature＋temperature difference”, the system may or not heat, here you
press the key “” and hold it for 5 seconds, the controller will enter the heat state forcibly when in the
heat state, and stop heating when the temperature is above “setting temperature＋temperature
difference”.
&Advanced Operation
Press the key “M” and hold it for 5 seconds, and if you have set the password, the LED display the
“PAS” to hint you to enter the password, you can use the key “↑” and “↓” to enter the password, if the
password is correct, the LED will display the parameter code, use “↑” or “↓” to select the parameter code
，Pressing the “set” key can make it to show the value of the parameter after select the parameter, here
you use “↑” or “↓” to set the parameter(pressing the key and not release can add or minus rapidly), then
press the “set” key to return to the state of showing parameter code after finishing setting. Pressing the
key “M” can exit the parameter setting state when display the parameter code, pressing the key “M”
means cancel when in the process of setting parameter, and the parameter will not be changed.
