INST LL TION
Installation area
Install the unit on a flat, horizontal and stable surface. An HVAC equipment pad is ideal, although 4“ thick
concrete blocks will work as well.
To optimize installation
Allow a minimum of 12” of clearance on all 3 sides, but ensure 36” in front of the service panel
Water connection
The heat pump can be connected to the filtration circuit b one of two methods:
1. With a 3-valve
b pass, placed after the pump and filter. This allows the user to regulate water flow to the pump and
isolate the unit completel for maintenance.
2. Inline with the
s stem. This will somewhat reduce the flow rate of the filtration s stem on large circulation pumps.
NOTE
If our pool has a water treatment s stem (chlorinator, salt generator, brominator etc...) installed, the b pass
must be installed before the water treatment. A check valve after the heater, before the treatment s stem is
recommended but not required.
Electrical connection
Electrical suppl must be installed b a licensed electrician. This unit uses a double pole, 230-240 Vac, 60 Hz
circuit, with a 20-amp breaker. The unit will use a maximum of 9 amps of electricit during operation.

M INTEN NCE
To protect the chassis, avoid placing objects on the device. External heat pump parts can be wiped with
a damp cloth and household cleaner. (Note: Never use cleaning agents containing sand, soda, acid or
chloride as these can damage the surface)
To prevent malfunctions due to sediment in the titanium heat exchanger, ensure that the heat
exchanger cannot be contaminated. In the event that operating malfunctions occur due to
contamination, the s stem should be cleaned as described below. (Warning: the fins on the tube heat
exchanger have sharp edges-use caution to avoid injur )
Cleaning the pipe system in the heat exchanger
Contamination in the pipes and heat exchanger can reduce the performance and efficienc of the pump.
Pressurized drinking water should be used b a technician to remove an of these substances.
Cleaning the air system
The finned heat exchanger, ventilator and condensation outflow should be cleaned of debris (leaves,
twigs, etc...) before each season. These t pes of contaminants can be manuall removed using
compressed air or b flushing with clean water. It ma be necessar to remove the device cover and air
inlet grid first.
The external fins can be cleaned with a spra on air conditioner condenser cleaner.
Note: Before opening the device, ensure that all circuits are isolated from the power suppl .
To prevent the evaporator and condensation tra from being damaged, do not use hard or sharp objects
for cleaning. Under extreme weather conditions, ice ma form on the air intake and exhaust air outlet
grids. If this happens, all ice from these grids must be removed to ensure that the minimum air flow rate
is maintained.
Winter Shutdown/Lay-up
If the outdoor temperature is expected to drop below the pump's operating limit (-5°C or 23°F) after the
swimming season has ended, the water circuit of the heat pump should be completel drained to avoid
damage.
For this, simpl disconnect the unions, and lean the heater 45' degrees to the side of the connections.
This will remove most/ all standing water from the tank. If ou are not confident that all water has been
removed, simpl insert a wet-dr vacuum hose into the bottom water port and vacuum out the
remaining water.
Attention: Warrant does not cover damages to the heat exchanger tanks.
