2.2 Dimensions

Installation and connections

3.1 Remarks
The box contains the heat pump, 2 water connections, and this manual. Other parts, including a bypass, must be provided by the user/installer.

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

1. All feeding of chemicals to the pool water has to be done downstream of the heat pump.
2. Always keep the unit straight up. If the unit has been tilted or put on its side, allow 24h before starting the unit.
3. The unit must always be installed outdoors.

3.2 Heat pump location
The unit will always perform very well, provided the following elements are present:

1. Fresh air
2. Electricity
3. Swimming pool filter pipes

The unit may be installed virtually anywhere OUTDOORS when the minimal distance to other objects is respected.

ATTENTION:
Do not install the heat pump in a closed room to prevent the intake of the cold exhaust air. Do not put it close to garden plants; they could block the intake of fresh air.  Blocking the air intake will cause insufficient operation and will result in lower production of heat.
Please check the drawing in paragraph 3.4 for minimum distances.

3.3 How 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 but stay a minimum of 2 meters away from the pool. Put it on a solid base. Keep the length of the piping as short as possible to limit heat loss. Insulating the piping will be useful.

3.4 Typical configuration

REMARK!
This setup is just an example.

3.5 Water connections
The piping to and from the heat pump needs to have a 50mm outer diameter and needs to be glued to the water connections that came with the heat pump.
These pipes can be hard PVC or flexible. Always install piping intended for swimming pool use and use the correct glue to put them together.
Alternatively flexible pool hose Ø38/Ø32 mm can be used with the included hose adapter and hose clamps.

3.6 Electrical connection
IMPORTANT!
Although the heat pump is electrically isolated from the swimming pool installation, this only prohibits electrical current to or from the swimming pool water. Grounding the heat pump is required to protect you against electrical shock caused by an eventual short circuit inside the unit. Make sure you have a solid grounding.
Always check if the voltage from the network corresponds with the operating voltage of the unit.
The heat pump must only operate together with the filter pump. Both should always be powered together.
Therefore, connect them to the same circuit breaker.
The heat pump will get damaged when operated without water flow and will void the warranty.
Please adhere to the following guidelines for the rest of the electrical installation:

Model| Power supply| Circuit breaker| Running
current| Cable section for
15m of cable| Cable section for
50m of cable
---|---|---|---|---|---
1299| 220-240V| 16A| 5.1 A| 2.5 mm-| 2.5 mm-
1094| 220-240V| 16A| 9 A| 2.5 mm-| 4 mm-

Values in this table are only guidelines. Check your local regulations.

The heat pump is supplied with a connection cable and can be plugged directly into an outlet.
The cable has standard a 10mA RCD.

ATTENTION:
Test the RCD before use as follows:

1. Plug the RCD into a fixed socket
2. Press the “RESET” button. The indicator should be “ON”.
3. Press the “TEST” button. The indicator should be “OFF”.
4. Press the “RESET” button again to start using the heat pump.

You should always switch off the heat pump immediately when the RCD indicator is turned “OFF”. Be extremely careful when pressing “RESET” after a failure because there might still be a problem.

3.7 Initial startup of the unit
The following steps need to be taken at startup (after verification that all the connections are made according to the specifications:

1. Turn on the filter pump. Check for possible water leakage and water flow to and from the swimming pool.
2. Put the power plug into the outlet and switch the heat pump ON. The unit will start after the time delay (see further).
3. Verify after a few minutes that the air exhausted by the heat pump is becoming cooler.
4. Allow the unit and pool pump to run 24 hours per day until the desired pool water temperature is reached. When the set temperature is reached, the unit just shuts off. The unit will now automatically restart when the pool temperature drops 1 degree Celsius below the set temperature.

Several days will be needed to bring the temperature of the swimming pool water to its required value, depending on the initial water temperature and the ambient temperature.
A good pool cover and insulation of the piping can shorten this period considerably.

NOTE:
It’s recommended to be patient at startup and wait until the pool temperature naturally reaches 15 degrees before starting up the heat pump.
This will result in rapid and energy-efficient heating of the pool water.
The water will also be heated if the startup temperature is below 8-15 degrees, but the heating time will be significantly longer and the energy consumption will be higher.

Time delay
The unit is equipped with a 3-minute built-in delay to protect control circuit components and to eliminate restart cycling and contactor chatter.

3.8 Condensation
By its operation of heating the swimming pool water, the air taken by the unit is cooled down and water may condense on the fins of the evaporator. If the relative humidity is very high, this could be as much as several liters an hour. Sometimes this condensation water is wrongly considered as swimming pool water.

Guidelines

4.1 Water chemistry
Special care should be taken to keep the chemical balance of your swimming pool within the following limits:

| Min.| Max.
---|---|---
pH| 7,0| 7.8
Free chlorine (mg/I)| 0,5| 1.5
TAC (mg/I)| 80| 150
TAC (° F)| 10| 30
Salt (g/1)| | 8

IMPORTANT!
Failure to keep the swimming pool water between the above limits will void the warranty.

NOTE:
When the concentration of one or more products mentioned above becomes too high, irrevocable damage to your heat pump may occur. Make sure that you always install water treatment equipment after the heat pump.
When an automatic chemical feeder is installed in the plumbing, it must be installed downstream of the heat pump.
A check valve must be installed between the heat pump and the chemical feeder to prevent back siphoning of chemically saturated water into the heat pump where it will damage the components.

4.2 Winterizing
CAUTION!
Failure to winterize could cause damage to the heat pump and will void the warranty. Although our Xpress heat pumps are protected against freezing, it is good practice to drain the complete installation. Perform the following actions to completely drain the heat pump:

1. Turn off the electrical power to the heat pump at the main breaker panel.
2. Shut off the water supply to the heat pump.
3. Disconnect the water inlet and outlet and let the water drain from the heat pump.
4. Re-connect the water inlet and outlet loosely to prevent debris from entering the connections.

4.3 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 problems.
• Connect the water inlet and outlet unions firmly.
• Turn on the filter pump to supply water to the heat pump.
• Restore electrical power to the heat pump and switch it ON.

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

1. Make sure the front of the unit is accessible for future service.
2. Keep the surrounding areas of the heat pump clear of all debris.
3. Keep all plants and shrubs trimmed and away from the heat pump.
4. Keep lawn sprinkler heads from spraying on the heat pump to prevent corrosion and damage. Use a deflector if needed.
5. 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.
6. Do not use the heat pump if any part has been underwater. Immediately call a qualified professional technician to inspect the heat pump and replace any part of the control system, which has been 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 increases. Visually inspect and clear the bottom drain port of any debris that could clog the port.
The WG heat pump can easily produce 10 to 20 liters of condensation. Stop the unit in case you feel that more water is being generated and wait for one hour to check for leakage inside.

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 is – TEST THE DRAIN WATER FOR CHLORINE – if there is no chlorine present, then it’s condensation.
Make sure that the air intake and exhaust are free from any restrictions. Avoid the cold exhaust air getting sucked back into the unit.

Usage and operation

5.1 The display

The heat pump can be turned on or off with the ON/OFF button.
When OFF the display is showing the following information:

• The indication ‘OFF’ at the location of the pool water temperature
• The temperature wanted for heating
• Eventual error messages

When ON the display is showing the following information:

• The temperature wanted for heating
• The pool water temperature
• The indication ‘Heating’ when the unit is heating the water
• A graphical representation of the water flow: the flow bar (see further)

5.2 Setting of the desired temperature
The desired temperature can directly be set with the arrow keys. The setting will automatically be stored in memory.
A choice can be made between °C and °F as follows:

1. Cut electrical power to the unit.
2. Press both arrow keys at the same time and restore electrical power to the unit, then release the keys.

5.3 The flow bar
The flow bar is a graphical representation of the water volume through the unit. The heat pumps have it best performance when the flow bar is in the green zone. The graph is only valid after at least 30 minutes of operation.
The flow bar also represents the three-minute time delay before the actual start of the unit. The indication “flow” is not visible;; the small block at the very right end of the flow bar is flickering and disappears after a while. When they are all gone, the unit will start.

Maintenance and inspection

6.1 Maintenance

• Check the water supply to the unit often. Low water flow and air entering into the system should be avoided, as this will diminish the units’ performance and reliability. You should clean the pool/spa filter regularly to avoid damage to the unit as a result of the dirty or clogged filter.
• The area around the unit should be dry, clean, and well-ventilated. Clean the side heating exchanger regularly to maintain good heat exchange and save energy.
• Check the power supply and cable connection often. Should the unit begin to operate abnormally or do you smell something unusual around the electrical compartment, switch off the heat pump and have it replaced in a timely manner.
• You should discharge the water at the bottom of the heat pump if the unit will not work for an extended period of time. The heat exchanger in the unit will not be damaged by frost but the remaining water in the piping can become ice. Check all parts of the unit and the installation carefully before starting.

6.2 Troubleshooting guide
Improper installation will create an electrical hazard, which could result in death or serious injury to pool users, installers, or others due to electrical shock, and may also cause damage to property.
DO NOT attempt any internal adjustments inside the heater.

1. Keep your hands and hair clear of the fan blades to avoid injury.
2. If you are not familiar with the pool filtering system and heater:
   • Do not attempt to adjust or service without consulting your dealer, professional pool or air conditioning contractor.
   • Read the entire installation and user’s guide before attempting to use, service or adjust the heater or pool filtering system.
   • Do not start the heat pump until 24 hours after installation to avoid damaging the compressor.

6.3 Error messages
The heat pump will show an error message in case of a problem. The following messages can occur:

the ambient temperature reaches 8°C.
“Overheat”| The heat pump is not capable of transferring all the heat it has generated.| Check the water flow.
“High air temp”| This is not a malfunction.
The unit is indicating that the ambient air temperature is high enough to operate without its fan. The fan is being switched off.|
“Low flow”| Insufficient water flow. The fan has stopped but the compressor is still running.| Check the water flow.
“Flow error”| There is too little water flowing through the heat pump and the unit is switched off.| Check/restore the water flow. The heat pump will start after a 3-minute delay when the flow is sufficient again.

Check the following point when verifying the water flow:

• Is the filter pump running?
• Is the filter pump producing enough water flow:
• Isn’t there too much dirt inside the skimmer basket?
• Isn’t there too much dirt inside the pre-filter of the filter pump?
• Is the sand filter clean enough: has it been backwashed regularly?
• Is the water opening in the pool large enough to allow for the desired flow?

NOTE:
A RESET of the heat pump is generated when the electrical power supply is interrupted
