Installation

The factory only provides the heat pump unit; the other items including an eventual bypass, in the illustration are necessary parts for the water system, provided by users or the installers.

Attention: Please follow these steps when installing the heat pump:

All feeding of chemicals to the pool water has to be done downstream of the heat pump.
Install a bypass when the flow of the pool pump is more than 20% above the rated flow of the heat exchanger of the heat pump.
Install the heat pump above the level of the pool water.
Install the heat pump on a solid foundation and use the damping rubbers to eliminate vibrations and noise.
Always keep the unit straight up. If the unit has been tilted or put on his side, allow 24h before starting the

Heat pump location

The unit may be installed virtually anywhere outdoors. For indoor pools please consult your suppliers. DO NOT put the unit in an enclosed area with a limited air volume where the unit discharge air will be recirculated. DO NOT put the unit next to shrubs, which can block the air inlet, Such locations deny a continuous source of fresh air, which reduce its efficiency and may prevent adequate heat delivery. The picture below give the minimum required distances from each side of the heat pump.

How to close to the pool

Install the heat pump as close to the swimming pool as possible to minimize the loss of heat through the piping. Put it on a solid base and place the rubber blocks under the heat pump to eliminate vibrations.

Distance from the pool

Normally, the pool heat pump is installed within a 7.5 meter radius of the pool. The greater the distance from the pool, the greater the heat loss from the piping. Since the piping is buried for the most part, heat loss is minimal for distances of up to 30 meters (15 meters to and from the pump= 30 meters total),unless the soil is wet or the water level is high. Heat loss per 30 meters could roughly be estimated at 0.6kw-hour (2000 BTU) for every 5 ℃temperature difference between the pool water and the soil surrounding th,we h icphip teranslates to an operation time increase of 3-5％.

Pool system set up

Connecting the by-pass (option)

VALVE1–Slightly closed( water pressure increased with just 100 to 200gr)
VALVE2 _Completely open
VALVE3–Half way open

Setting the valve of the by-pass:

```
* -Set all 3 valves entirely open
```
- -Slightly close valve 1 ( see also 3.6)
- -Close valve 3 about half way to adjust the refrigerant pressure

Electrical wiring

Note: -Verify the local power supply and the operating voltage of the heat pump. It is recommended to use a separate circuit breaker(slow type-D curve)for the heat pump together with the proper wiring characteristics (see table below). The current to the heat pump should only be applied when the filter pump is running. For example a relay controlled by the filter pump could be used to activate the current to the heat pump. Further connect the electrical supply to the junction box inside the unit. All PRO heat pumps require single-phase connection.

Grounding the heat pump is required to protect you against electrical shock caused by an eventual short circuit inside the unit. The heat pump is not equipped with a flow switch or any other kind of water flow detection. Therefore, the heat pump has to be wired electrically together with the filter pump to ensure water flow while the heat pump is running.

Initial start-up

Turn on the filter pump, check for leaks and verify flow to and from the pool.
Turn on the electrical power supply to the unit, then press the ON/ OFF key on the electronic control panel. The unit should start when the time delay period has lapsed .
When the unit has been running for a couple of minutes, check if the air leaving the unit is cooler.
Check the performance of the flow switch as follows: with the unit running, turn the filter pump off. The unit should also switch off automatically. If not, the flow switch must be readjusted.
All the unit and filter pump to run 24 hours a day until the desired pool water temperature is reached.

When the set temperature is reached, the unit switches itself off. The unit will now automatically restart (as long as your filter pump is running) when the temperature of the pool water experiences a drop of more than 1℃ below set temperatur.e Depending on the starting temperature of the pool water and the air temperature, it can take several days for the water to reach the desired temperature. Covering the poolcan drastically reduced this period.

Water flow switch—the unit is equipped with a flow switch that is switched on when enough water has flowed through the unit and that is switched off when the water flow becomes too low. (e.g. when the filter pump is switched off ).

Time delay —the unit is equipped with a built-in 3-minute start delay included to protect electrical .components and contacts —the unit is equipped with a built-in 3-minute start delay included to protect electrical .components and contacts

After this time delay, the unit will automatically be restarted. Even a brief interruption of the power supply will activate the start delay and prevent the unit from starting immediately. Additional interruptions of the power supply during the delay period will have no effect on the 3-minute countdown.

condensation

When the swimming pool water is being heated by the heat pump, the incoming air is cooled down quite a bit, which can cause condensation on the fins of the evaporator. Condensed volumes can attain severa l litres per hour underhigh atmospheric humidity. Sometimes, this is wrongfully interpreted as a water leak.

Guidelines

| Min| Max
---|---|---
pH| 7.0| 7.4
Free chlorine(mg/1)| 0.5| 1.2
TAC(mg/1)| 80| 120
Salt(g/1)| | 3

Water chemistry Special attention should be paid to the chemical balance of the pool water. The pool water values should always stay within the following limits:

Important: failure to comply with these limits will invalidate the warranty.
Note : exceeding one or several limits can damage the heat pump beyond repair. Always install water treatment equipment past the heat pump’s water outlet, especially if the chemicals are automatically added to the water. A check-valve should also be installed between the outlet of the heat pump and this equipment in order to prevent products from flowing back into the heat pump if the filter pump stops.

Winterizing

Important: failure to winterizing could damage the heat pump and will void warranty The heat pump, filter pump, filter and conduits must be protected in areas where the temperature can drop below the freezing point, Evacuate all water from the heat pump as follows:

Turn off the electrical power supply to the heat pump
Close the water supply to the heat pump: completely close valves 2 and 3 of the by-pass
Disconnect the water inlet and outlet coupler fittings of the heat pump and let the water drain out of the unit

Spring startup

If your heat pump has been winterized, perform the following steps when starting the system in the spring:

Inspect the system for any debris or structural poroblems.
Connect the water inlet and outlet unions firmly.
Turn on the filter pump to supply water to the heat pump. Adjust the by-pass to allow water flow through the heat pump.
Turn on the electrical power to the heat pump at the main breaker panel.

Owner inspection

The heat pumps are designed and constructed to provide long performance life when installed and operated properly under normal conditions. Periodic inspection are important to keep your heat pump running safe and efficiently all the years.
The following basic guidelines are suggested for your inspection:

Make sure the front of the unit is accessible for future service.
Keep the surrounding areas of the heat pump clear of all debris.
Keep all plants and shrubs trimmed and away from the heat pump.
Keep lawn sprinkler heads from spraying on the heat pump to prevent corrosion and damage.
If the unit is installed under a very sharp roof pitch or under a roof without a gutter, a gutter or diverter should be fitted to prevent excessive water from pouring down onto the unit.
Do not use the heat pump if any parts has been under water. Immediately call a qualified professional technician to inspect the heat pump and replace any part of the control system, which has be submerged.

The heat pump will produce condensation(water) while in operation. The heat pump base is designed to allow the condensation to exit through the bottom drain port. The condensation will increase as the outdoor air humidity level increase. Check the following at regular intervals to ensure proper condensate drainage:

Visually inspect and clear the bottom drain port of any debris that could clog the port.
Keep the air intake area and discharge area clear of debris so the airflow through the heat pump is not restricted. The cooler discharge air should not accumulate and be drawn into the side air intake coils.

During normal operation, the heat pump produces ten to twenty liters of condensate per hour. If condensate drainage is above this range during operation or if water continues to drain from the base when the heat pump is not in operation for more than an hour, a leak in the internal plumbing may have occurred. Call a qualified heat pump technician to investigate the problem.

NOTE: A quick way to verify that the water running through the drain is condensation water is to shut off the unit and keep the pool pump running. If the water stops running out of the base pan, it is condensation water.
AN EVEN QUICKER WAY TEST THE DRAIN WATER FOR CHLORINE–if there is no chlorine present, then it’s condensation.
