INSTALLATION AND CONNECTION

Functional Diagram

Note : The swimming pool heat pump unit is sold without any treatment or filtration equipment. The components presented in the diagram are spare parts to be supplied by the installer.

Heat pump unit
Place the heat pump outdoors and away from any enclosed technical space.
Placed under a shelter, the minimum required distances mentioned below must be respected in order to avoid any risk of air recirculation and a deficiency in the unit’s overall performance.

It is advised to install the unit on a dissociated cement block or a mounting bracket designed for this use and to set up the unit on the supplied rubber bushing (fastenings and washers not supplied).
The maximum installation distance between the unit and the swimming pool is 15 metres.
The total length of the piping to and from the unit is 30 metres.
Insulate both the above ground and buried hydraulic piping.
The heat pump must be installed at a minimum distance from the pool in compliance with NF C 15-100 (3.5 m from the water for France) or in compliance with installation standards applicable in other countries.
Do not install the heat pump close to a heat source.
For installation in snowy regions we recommend sheltering the machine to avoid snow accumulating on the evaporator.

Hydraulic connection
The unit is supplied with two 50 mm Ø union connections. Connect the water inlet to the heat pump coming from the filtration group then connect the water outlet to the heat pump at the water conduit going to the pool (see diagram below).

Install a by-pass valve between the heat pump entrance and exit.

• If an automatic distributor or an electrolyze is used, it should be installed imperatively after the heat pump with the goal of protecting the titanium condenser against an elevated concentration of chemicals.
• Be sure to install the by-pass valve and the supplied union connections at the water inlet and outlet level in order to simplify purging during the winter period and to facilitate access when disassembling for maintenance.

Electrical connection
Electrical installation and wiring for this equipment must be in conformity with local installation standards.

230V  +/- 10 % 50 Hz 1 Phase
See the corresponding wiring diagram in the appendix.
The connection box is located on the right side of the unit. Three connections are designed for the power supply and two are for controlling the filter pump (Enslavement).

The electrical power supply must have, when appropriate, a fuse protection device like a feed motor (aM) or D curve circuit breaker as well as a differential circuit breaker 30mA (see following table).

• Use an RO 2V/R 2V or equivalent power cord.
  The cables sections are given for a maximum length of 25 m. They must however be checked and adjusted according to the installation conditions.
  Always shut down the main power supply before opening the electrical control box.

3.5 Initial start-up
Start-up procedure – After installation is complete, follow these steps:

• Rotate the fans by hand to verify that they can turn freely by hand, and that the turbine is correctly affixed to the motor shaft.
• Ensure that the unit is connected correctly to the main power supply (see the wiring diagram in the appendix).
• Activate the filtration pump.
• Verify that all water valves are open and that the water flows toward the unit before switching on the heating or cooling mode.
• Verify that the drainage hose is correctly affixed and that it causes no obstructions.
• Activate the unit power supply, then press the On/Off button on the control panel.
• Make sure the alarm or lock symbols are not displayed. If need be, see the trouble-shooting guide (see § 6.4).
• Set the water flow using the by-pass valve (see § 3.6 and 2.1), as provided for by each model, to obtain an Entry/Exit temperature of 2°C.
• After running for several minutes, verify that the air exiting the unit is cool (between 5 and 10°).
• With the unit operating, turn off the filter pump. The unit should automatically turn off and display error code E03 (See § 6.4).
• Allow the unit and the pool pump to run 24 hours per day until the desired water temperature has been reached. When the set water inlet temperature is reached, the unit will turn off. It will automatically restart (as long as the pool pump is running) if the pool temperature is at least 0.5°C below the set temperature.

Water flow switch – The unit is equipped with a flow switch that turns on the heat pump when the pool filtration pump is running, and deactivates it when the filtration pump is out of order. If the water is low, the E03 alarm code will appear on the regulator (See § 6.4).

Time delay – The unit is equipped with a time delay of 3 minutes in order to protect the control circuit components, to eliminate restart cycling and contactor chatter. Thanks to this time delay, the unit automatically restarts approximately 3 minutes after each control circuit interruption. Even a brief power interruption will activate the restart time delay.

USER INTERFACE

Water flow setting
While the heat pump is running and the water inlet and outlet valves are open, adjust the by-pass valve to obtain a difference of 2°C between the water inflow and outflow temperature (see Functional Diagram Section 3.1).
You can check the setting by viewing the inflow and outflow temperatures directly on the control panel by following the procedure below.

Then adjust the by-pass to obtain a difference of 2°C between the inflow and the outflow.
Press once to exit the menu.

Note: Opening the by-pass valve creates a weaker flow which results in an increased ∆T.
Closing the by-pass valve creates a stronger flow which results in a decreased ∆T.

SILENT function activation/deactivation
Silence mode enables the heat pump to be used in economic and very silent mode when the heating needs are low (maintaining the pool temperature or need for ultra-silent operation).
This function can be Activated/Deactivated manually.

MAINTENANCE AND WINTERISING

Maintenance
These maintenance operations must be carried out once per year in order to guarantee the longevity and the good working condition of the heat pump.

• Clean the coil with the help of a soft brush or jet of air or water (Warning, never use a high pressure cleaner).
• Verify that the drains flow well.
• Verify the tightening of the hydraulic and electrical connections
• Verify the hydraulic sealing of the condenser.
• Have the leak-tightness of the cooling circuit to the leak detector checked by an accredited professional.

Before any maintenance operation, the heating pump must be disconnected from any electrical current source. The maintenance operations must only be carried out by personnel that is qualified and authorised to handle liquid refrigerants.

Winterising

• Put the heat pump in “OFF” mode.
• Cut the power supply to the heat pump.
• Empty the condenser with the help of the drain to avoid any risk of deterioration. (high risk of freezing).
• Close the by-pass valve and unscrew the entry/exit connection unions.
• Eliminate the maximum amount of residual stagnant water from the condenser with the help of an air gun.
• Close the water entry and exit areas of the heating pump to avoid introducing foreign bodies.
• Cover the heating pump with a dedicated winterizing case.

Any damage caused by poor winterising maintenance will lead to cancellation of the warranty.
