4. POSITIONING
Choosing the area where your heat pump will be installed is extremely important. You must respect the
following guidelines.
4.1 Ventilation and accessibility
Your heat pump works, in large part, in symbiosis with the surrounding air: it is important that there be
adequate ventilation all around the heat pump. Therefore, the device should not be installed in a closed
space such as a garden shed or a basement.
Important:Your heat pump must have sufficient free space around it to function properly.
You should also clear any obstructions surrounding the heat pump, as indicated in the table below:
ALL MODELS
(1) in front of the evaporation coil
60 cm = 2 feet
(2) in front of all other surfaces
120 cm = 4 feet
(3) in front of the fan*
120 cm = 4 feet
(4) in front of the service panel
120 cm = 4 feet
*Objects should be placed as far away as possible from the area where air is evacuated.
4.2 Other recommandations
You should not install the device below a roof, so that your heat pump becomes buried under snow or
receives too much water if the roof is not fitted with gutters. Do not install your heat so that the sun
directly hits the regulator. This will not cause damages, but the display will be harder to read.
Similarly, you should not install automatic sprinkler near your pool heat pump. The device must be
installed on a flat, firm and level surface. A concrete slab or equivalent is preferred. Consider that your
device will produce condensation, so there will be water leaking around the unit.
It is highly recommended to use a solar blanket to cover the pool in order to reduce the heat and
loss, mainly during colder nights

4.3 Water supply and backflow plumbing connections
All STRATOS model connections have a 1 ½’ diameter.
4.4 Minimum and maximum water flows
For maximum efficiency, your heat pump must operate with water flows between 57 liters per minute
(15 U.S. gallons per minute) and 170 liters per minute (45 U.S. gallons per minute). With a water flow
of less than 57 lpm (15 U.S. GPM) and greater than 170 lpm (45 U.S. GPM), the heat pump will not
work properly and will suffer damage. (See table below).
Aset of valves (Fig. A) to isolate the heat pump and adjust the water flow must be installed.
We recommend installing this set of valves (Fig. A) in order to be able to adjust the optimal water flow
circulating in the heat exchanger (condenser). An adjustable automatic bypass valve must be installed
when a water pump of 2 HP or more is used to circulate the pool water.
Your water pump must be able to supply each heat pump with a water flow within the limits listed
below.
MODEL MINIMUM IDEAL MAXIMUM
STRATOS 40-50-65-80-100 57 l/m (15 GPM US) 170 l/m (45 GPM US) 170 l/m (45 GPM US)
1 U.S. gallon per minute (1GPM US) = 3.78 liters per minute (3.78 l/m)
WARNING
If the above-prescribed water flows are not respected,
damage will ensue and your warranty will be void.
WARNING
Pool heat pumps normally operate with (12-15 PSI) water pressure.
The maximum operating water pressure is 2.0 bars (30 PSI). Failure
to respect the prescribed water pressures will void the warranty of
your heat pump.

5. CHLORINATORS, BROMINATORS AND OTHER AUTOMATIC SYSTEMS
5.1 Basic connections, inline chlorinator or brominator
This connection is mandatory to ensure the long working life of your pool heat pump.
Any automatic distribution system for chemicals, chlorine, bromine or other, must be installed so that
the distribution system’s water output is located after the pool’s heat pump. The heat pump’s warranty
will be void if the installation is not compliant to this rule.
5.2 Salt chlorinators
Salt chlorinators are made to be installed as inline chlorinators. Therefore, they must be installed as
prescribed in the section above (“inline chlorinator or brominator”).
5.3 Pressurized chlorinator or brominator
Pressurized chlorinators or brominators start by using a small quantity of water as it exits the filter, then
add chemicals and forward this highly concentrated solution into the pool. Check valves must therefore
be extremely resistant to corrosion. Only use the valves that have been supplied or recommended by
the manufacturer of your chlorinator or brominator.

6. CONNECTION TO ELECTRICAL POWER
WARNING
To ensure your safety and the proper functioning of the device, the electrical
connections must be performed by a qualified electrician according to national
codes, provincial and local regulations.
A circuit breaker must be installed close to the heat pump, in an accessible location.
Never open the electrical box without shutting off the power to all sources used for the operation of the
heat pump. If your heat pump has a pool pump control option, remember to close the circuit breaker to
this pump.
The spec sheet for the heat pump contains all the requirements for voltage and amps.
If the power cord is damaged, it must be replaced by a qualified electrician.

8. TESTING
8.1 Inspection before use
•Check installation of the whole machine and the pipe connections according to the pipe
connecting drawing; (Blue water IN / Red water OUT)
•Check the electric wiring according to the electric wiring diagram; and grounding connection.
•Make sure that the main machine power switch is off
•Check the temperature setting.
•Check the air inlet and outlet.
8.2 Trial
•The user must “Start the Pump before the Machine, And Turn off the Machine before the
Pump,” or the machine will be damaged.；
•The user should start the pump, check for any leakage of water; and then set suitable
temperature in the thermostat, and then switch on power supply.
•In order to protect the swimming pool heater, the machine is equipped with a time lag starting
function, when starting the machine, the blower will run 3 minutes earlier than the compressor.
•After the swimming pool heater starts up, check for any abnormal noise from the machine.
9. PRECAUTIONS
9.1Attention
•Set proper temperature in order to get comfortable water temperature; to avoid overheating.
•Please do not stack substances that can block air flow near inlet or outlet area, or the efficiency
of the heater will be reduced or even stopped.
•Please do not put hands into outlet of the swimming pool heater, and do not remove the screen
of the fan at any time.
•If there are abnormal conditions such as noise, smell, smoke, and electrical leakage, please
switch off the machine immediately and contact the local dealer. Do not try to repair it yourself.
•Do not use or stock combustible gas or liquid such as thinners, paint and fuel to avoid fire.
•In order to optimize the heating effect, please install heat preservation insulation on pipes
between swimming pool and the heater. During running period of the swimming pool heater,
please use a recommended cover on the swimming pool.
•Connecting pipes of the swimming pool and the heater should be ≤10m, or the heating effect
of the heater cannot be ensured.
WARNING
Do not use means to accelerate the defrosting process or to clean, other than
those recommended in this manual

9.2 Safety
•Please keep the main power supply switch far away from the children.
•When a power cut happens during running, and later the power is restored, the heater will start
up automatically. So please switch off the power supply when there is a power cut, and reset
temp when power is restored.
•Please switch off the main power supply in lightning and storm weather to prevent from
machine damage that caused by lightning.
•If the machine is stopped for a long time, please cut off the power supply and drain water out
of the exchanger by disconnecting the inlet/outlet pipe.
9.3 Warning
