INSTALLATION

Installation information

The following information given here is not an instruction, but simply meant to give the user  better understanding of the installation.

Condition of installation

The following information given here is not an instruction, but simply meant to give the user a better understanding of the installation.

Installation place

Install the swimming pool heat pump on a flat, horizontal, and stable surface. Maintain 1m of open space in front of the grille and 3m on the outlet side of the ventilator. And reserve enough space to allow access to operate controller. Make sure that the outlet air will not be breathed in.

To perfect your installation

• Avoid directing the flow of ventilated air towards a sensitive noise zone, such as room’s window.
• Avoid positioning pool heat pump on a surface that can transmit vibrations to dwelling.
• Try to avoid placing appliance under a tree or exposed to water or mud, which would be likely to complicate maintenance.

Water connection

• The heat pump is connected to a filtration circuit with a by-pass.
• It is imperative that the by-pass is placed after the pump and the filter.
• The by-pass generally consists of 3 valves.
• This makes it possible to regulate the water flow which passes through the heat pump and to isolate the heat pump completely for any maintenance work, without cutting the flow of filtered water.
  

If your installation is equipped of the water treatment with product adductions (e.g. chlorine, brominates, salt…) the by-pass must be installed before the water treatment, with a non-return valve between the by-pass and water treatment.

Electrical connection

• Electrical supply must correspond to that indicated on the appliance.
• Connection cables have to be sized according to appliance power and installation requirements

Please refer to below table: 

• These data are only indication, you must ask an electrician to determine the exact data for your pool installation.
• Use the cable glands and grommets provided inside the heat pump to route cables

STARTING UP FOR THE FIRST TIME

After all the connections have been made and checked, the following steps must be taken:

1. Turn on the filter pump. Check for leaks and make certain that the water flows from and to the swimming pool.
2. Connect the power supply to the heat pump and press the ON/OFF button. The appliance will start up after the time delay (see below) has elapsed.
3. After a few minutes check whether the air being expelled from the appliance is cooler.
4. Leave the appliance and filter pump in operation 24 hours per day until the desired water temperature has been reached. At this point the heat pump ceases operation. The appliance will now start up again automatically (as long as the filter pump is in operation) whenever the swimming pool temperature falls to 1 degree below the programmed temperature.

Depending on the initial temperature of the swimming pool water and the air temperature, several days may be needed to bring the water up to the temperature required. Covering the swimming pool properly can considerably shorten this period.

Time Delay – the appliance is fitted with built-in start-up delay of 3 minutes as protection for the electronics and to increase the life of the contacts. After this interval, the appliance will restart automatically. Even a brief interruption in the flow of current will activate this delay and thus prevent the appliance from starting up immediately. Additional interruptions in the current during this delay will have no influence on the 3-minute countdown.

Protection Functions

T2 under-temperature protection

In heating mode, if T2 is detected equal to or lower than T2LS (7°C) for consecutive 5s, T2 under-temperature protection will be reported. The unit will not start if there is no load, and
will stop load output if it is already started.
When T2 is higher than T2LS plus 2 degrees, the protection is automatically removed. Shutting down or switching the mode to cooling will clear this protection.

T1 sensor fault

If the thermostat detects that T1 is higher than 99°C for consecutive 5s, the fault of T1 sensor short-circuit is reported. If T1 is detected lower than –40°C for consecutive 5s, the fault of T1 sensor open-circuit is reported. In either case, the load automatically stops running.
The fault automatically recovers. Shutting down or mode switching cannot clear the fault.

T2 sensor fault

When T2 sensor is disabled, the corresponding control logic and troubleshooting are invalid.
If the thermostat detects that T2 is higher than 99°C for consecutive 5s, the fault of T2 sensor short-circuit is reported. If T2 is detected lower than –40°C for consecutive 5s, the fault of T2 sensor open-circuit is reported. In cooling mode, the alarm is generated but the fault is not rectified. In heating mode, the unit is stopped for troubleshooting.
The fault automatically recovers. Except disabling T2 sensor, shutting down or mode switching cannot clear the fault.

Fault Codes 

Attention: The above codes can also be used to represent low voltage faults, because low voltage switches and temperature sensors are connected in series, this situation may be caused by refrigerant leakage. It is necessary to find professional maintenance personnel.

MAINTENANCE

To protect the paintwork, avoid leaning or putting objects on the device. External heat pump parts can be wiped with a damp cloth and domestic cleaner. (Attention: Never use cleaning agents containing sand, soda, acid or chloride as these can damage the surfaces.)
To prevent faults due to sediments in the titanium heat exchanger of the heat pump, ensure that the heat exchanger cannot be contaminated (water treatment and filter system necessary).
In the even that operating malfunctions due to contamination still occur, the system should be cleaned as described below.
(Warning: the fins on the finned tube heat exchanger are sharp-edged — danger of being cut!)

Cleaning the pipe system in the heat exchanger

Contamination in the pipes and heat exchanger can reduce the performance of the heat pump’s titanium heat exchanger. If this is the case, the pipe system and heat exchanger must be cleaned by a technician.

Use only pressurized drinking water for cleaning.

Cleaning the air system

The finned heat exchanger, ventilator and condensate outflow should be cleaned of contaminants (leaves, twigs, etc.) before each new heating period. These types of contaminants can be manually removed using compressed air or by flushing with clean water.
It may be necessary to remove the device cover and air inlet grid first.

Attention: Before opening the device, ensure that all circuits are isolated from the power supply.

To prevent the evaporator and the condensate tray from being damaged, do not use hard or sharp objects for cleaning.
Under extreme weather conditions (e.g. snow drifts), ice may form on the air intake and exhaust air outlet grids. If this happens, the ice must be removed in the vicinity of the air intake and exhaust air outlet grids to ensure that the minimum air flow rate is maintained.

Winter Shutdown/Lay-up

If there is a chance of frost after the bathing-season has ended when the swimming pool heating is switched off and the external temperature is expected to drop below the operating limit, the water circuit of the heat pump should be completely drained. Otherwise, suitable constructional measures should be taken by the customer to protect the heat pump against damage from frost.

Attention: The warranty does not cover damage caused by inadequate lay-up measures during the winter.
