How to Install a Aquatemp Heat Pump Pool Heater

This is a simplistic guide on the correct way in which to install a Aquatemp Heat Pump Pool Heater.

Please consult the manual supplied with your pool heater for more information. The warnings and instructions contained in the manual supplied with your Aquatemp Heat Pump Pool Heater must be carefully read and understood as they provide important information relative to handling and operating safety.

The installation must be done by qualified professionals.

PHYSICAL LOCATION

The placement of the swimming pool heater is very important in keeping installation costs to a minimum, while providing for maximum efficiency of operation as well as allowing adequate service and maintenance access.

The Aquatemp Heat Pump Pool Heater may be installed virtually anywhere outdoors. Normally, the pool piping layout and the electrical supply will dictate the general location of the Aquatemp Heat Pump Pool Heater. In addition, the following guideline should be adhered to when picking the location:

1. The Aquatemp Heat Pump Pool Heater must not be installed in a totally enclosed area such as a shed, garage, etc. Re-circulation of cold air discharge back into the evaporator coil will greatly reduce swimming pool heat pump pool heater heating capacity and efficiency.

2. Depending on the model, the Aquatemp Heat Pump Pool Heater can be fitted with a vertical or horizontal discharge fan. Air is pulled through the evaporator coil and is discharged through the fan grille. Avoid any overhangs or structures which could cause exhaust air to re-circulate from the fan side of the unit back into the evaporator coil sides. Allow minimum clearances (refer to owner's manual) of open area around the Aquatemp Heat Pump Pool Heater for good air circulation and service access.

3. Mount the unit on a sturdy, level base to aid in condensation and rain water drainage. A cement slab will provide an inexpensive attractive easy to level mounting base with good drainage.

4. If the Aquatemp Heat Pump Pool Heater is installed below a roof overhang or roof valley that has no gutter, a gutter or diverter should be fitted to prevent excessive water from pouring onto the unit.

PLUMBING

The Aquatemp Heat Pump Pool Heater should be located as close as practical to the existing pool pump and filter to minimize water piping. Normally, the pool pump and pool heater are installed close together and within 8 meters of the pool. The longer the distance from the pool, the more heat loss from the piping. Since most of the time the piping is buried, the heat loss is minimal for runs of up to 15 meters (15 meters to and from the pump = 30 meters total) unless the ground is wet or the water table is high. A very rough estimate of heat loss per 30 meters of piping is 0.7321875 kW/Hr. for every 5°C difference in temperature between the pool water and the ground surrounding the pipe, which translates to about a 3% to 5% increase in run time.

The water connections on the Aquatemp Heat Pump Pool Heater are threaded coupled unions for use with rigid 50 mm PVC pipe, see typical installation diagram. If rigid PVC is not available or not practical, you can use re-enforced, flexible hose with PVC fittings stainless steel clamps. Unions to be hand tightened only. Water Inlet union is on the left, water outlet on the right.

The piping sequence: pool → pump → filter → heat pump → salt-water chlorinator (if used, must be positioned downstream of the heater.) → pool. When the piping installation is complete, operate the pool pump and check the piping installation for leaks.

The Aquatemp Heat Pump Pool Heaters FULL FLOW Titanium heat exchanger has a minimal pressure drop and requires NO SPECIAL PLUMBING arrangement. It should be considered as just another length of PVC pipe in your pool filtration system. Be sure the pool water is allowed to circulate freely through the pool heater in order for it to operate. Water flow through the Aquatemp Heat Pump Pool Heater should be free of air.

ELECTRICAL

WARNING: DO NOT ATTEMPT TO COMPLETE ANY ELECTRICAL INSTALLATION OR SUPPLY CIRCUIT WIRING UNLESS YOU ARE QUALIFIED AND EXPERIENCED IN THE FIELD. AQUATEMP HEAT PUMP POOL HEATERS MUST BE INSTALLED IN COMPLIANCE WITH VALID ELECTRICAL REGULATIONS (CURRENT SPECIFICATIONS SANS 10142-1 WITH ALL ELECTRICAL CODES), AND MUST BE DONE ONLY BY QUALIFIED DEALERS WITH PROPER TRAINING AND LICENSES OR A LICENSED PROFESSIONAL ELECTRICIAN.

 

Depending on the Aquatemp Heat Pump Pool Heater model, 220V AC / 50Hz / 1ph or 380V AC / 50Hz / 3ph with a neutral from a dedicated circuit breaker is the only power supply required for the unit. Connect the proper size cable (including earthing) to a dedicated AC power supply branch circuit equipped with the proper circuit breaker.

An earth leakage protection device with a rated earth leakage tripping current (rated residual current) which complies with valid electrical regulations (CURRENT SPECIFICATIONS SANS 10142-1 WITH ALL ELECTRICAL CODES) must be installed at the main power supply for the electrical equipment in the pool system. This is a circuit protection which virtually eliminates shock hazard as well as equipment damage due to a earth leakage fault.

INITIAL START-UP AND SYSTEM CHECK

Please read completely through this section BEFORE STARTING UNIT.

 

IMPORTANT: the Aquatemp Pump Pool Pool Heater is equipped with a five minute built in start-up delay timer to protect control circuit components and to eliminate restart cycling and contactor chatter. This time delay will automatically restart the unit in approximately 2 to 5 minutes (depending on model installed) after each control circuit interruption.

After installation is completed and the unit is ready to start, follow these steps:

1. Turn on your filter pump, check for leaks and verify flow to and from the pool.

2. Turn on the electrical power supply to the Aquatemp Heat Pump Pool Heater. The unit should start after 5 minutes.

3. Set the desired pool water temperature on the Aquatemp Heat Pump Pool Heater controller.

4. After running a few minutes check that the air leaving the unit is between 5 to 7 degrees Celsius cooler than the ambient air.

5. With the Aquatemp Pool Heater operating, turn the filter pump off. The Aquatemp Heat Pump Pool Heater should also turn off automatically due to lack of waterflow.

6. Restart the pump/filter. The Aquatemp Heat Pump Pool Heater should start after the initial start-up delay timing.

7. Allow the Aquatemp Heat Pump Pool Heater and pool pump to run 24 hours per day until desired pool water temperature is reached. Once the set temperature is achieved re-set your pool timer for the filter pump to run 8 - 12 hours per day. Your Aquatemp Heat Pump Pool Heater will automatically restart (as long as your pool pump is running) when the pool temperature drops more than 1° C below the set temperature.
