Installation and connections

Notes

The factory supplies only the heat pump. All other components must be provided by the user or the installer.
Install a bypass if the water flow from the water pump is more than 20% greater than the allowable flow through the heat exchanger of the heat pump.
Always place the heat pump on a solid foundation and use the included rubber mounts to avoid vibration and noise. Always hold the heat pump upright. If the unit has been held at an angle, wait at least 24 hours before starting the heat pump.

Heat pump location
The unit will work properly in any desired location as long as the following three items are present:

Fresh air
Electricity
Adequate water flow

The unit may be installed in virtually any outdoor location as long as the specified minimum distances to other objects are maintained (see drawing below). To protect the unit from snow and rain, it is suggested to add an open sides shed cover over the heat pump. Please consult your installer for installation with an indoor spa. Installation in a windy location does not present any problem at all, unlike the situation with a gas heater (including pilot flame problems).

ATTENTION:
Never install the unit in a closed room with a limited air volume in which the air expelled from the unit will be reused, or close to shrubbery that could block the air inlet. Such locations impair the continuous supply of fresh air, resulting in reduced efficiency and possibly preventing sufficient heat output.
See the drawing below for minimum dimensions.

Distance from your spa
The heat pump is normally installed within a perimeter area extending 2m (6.5ft) from the spa. To minimize heat lost, it is recommended to add insulations over the pipes connecting the heat pump and the spa.

Plumbing Connections

Plumbing diagram

Check-valve installation (recommended)

If automatic dosing equipment for chlorine and acidity (pH) is used, it is essential to protect the heat pump against excessively high chemical concentrations which may corrode the heat exchanger. For this reason, equipment of this sort must always be fitted in the piping on the downstream side of the heat pump, and it is recommended to install a check valve to prevent reverse flow in the absence of water circulation.
Damage to the heat pump caused by failure to follow this instruction is not covered by the warranty.

Electrical connection
DANGER : Electrical connections below must be done by a qualified and licensed electrician. Failure to do so injury or death may occur.

Turn the spa breaker to the OFF position before making an electrical connection.
Make sure the electrical ratings of the power source match with the electrical ratings marked on the label of this unit.
Attention: This unit is provided with a grounding lug and must be electrically bonded to the spa common bonding grid. Connect the grounding lug with the spa common bonding grid with a #8 minimum solid copper wire.
Power to this unit must be supplied through a GFCI having a rated residual operating current not exceeding 5mA.
Connect the unit to the 120VAC AV port of the spa controller. A splitter (PN 22934, not included) may be needed if the AV port is being used for other equipment.
If a spa controller is not used, the unit may be hard-wired to a 120VAC power supply panel which must be done by a licensed electrician. The unit may also be plugged into a dedicated 120VAC power supply junction box.

Initial operation
Note : In order for the heat pump to operate, the water circulating pump must be running to cause the water to circulate through the heat pump. The heat pump will not start up if the water is not circulating.
After all connections have been made and checked, follow the following procedure:

Switch on the water circulating pump. Check for leaks and verify that water is flowing from and to the spa.
Switch on the power to the heat pump.
Press the Power button on the front panel for 2 seconds.
Set the unit to Heat or Cool mode by pressing the Mode button. Heating = Red LED on. Cooling = Green LED on.
Set the temperature by pressing the Up or Down buttons.
The unit will start up after the time delay expires.
After a few minutes, air will be blowing out of the fan grill.
Complete!

Time delay – The heat pump has a built-in 3-minute start-up delay to protect the circuitry and avoid excessive contact wear. The unit will restart automatically after this time delay expires. Even a brief power interruption will trigger this time delay and prevent the unit from restarting immediately. Additional power interruptions during this delay period do not affect the 3-minute duration of the delay.

Condensation
In heat mode, the air drawn into the heat pump is greatly cooled by the operation of the heat pump for heating the spa water, which may cause condensation on the fins of the evaporator. The amount of condensation may be as much as several litters per hour at high relative humidity. This is condensation water, not leaked water.

Maintenance

Maintaining your spa heat pump is crucial to ensure its optimal performance and longevity. Here are some essential maintenance instructions for your spa heat pump:

Regular cleaning: Keep your spa heat pump clean by removing any debris, leaves, or dirt that may have accumulated around it. Use a soft-bristle brush to clean the outer surfaces of the heat pump.
Check the water supply system regularly to avoid the air trapped in the system and the occurrence of low water flow, because it would reduce the performance and reliability of heat pump.
Remove all water from the heat pump if it will not be used for a long period of time (especially during the winter).
After the unit has been properly winterized, it is recommended to cover the heat pump with a special winter cover.
After a long winter shutdown, before starting to run the heat pump again, make sure the spa is filled with fresh and clean water and all valves to the heat pump are open.
When the unit is running, it is normal that there is some water discharged under the unit all the time.
Schedule professional maintenance: Schedule regular maintenance with a licensed professional to ensure that your spa heat pump is in good working condition. A professional technician can identify and fix any issues before they turn into bigger problems.

Following these maintenance instructions can help keep your spa heat pump running smoothly and efficiently, ensuring that you enjoy a relaxing and comfortable spa experience.
