Key points that should be taken into consideration for heat pump placement:

• Distance from the application(s) the heat pump services as any length of pipe installation will cause heat loss.
• Air circulation should be taken into consideration as a poorly placed heat pump that re‐circulates the cold air expelled from the fan can cause unnecessarily high running costs and in some situations failure to attain the desired temperature.

Physical Placement

• Prepare a level area with concrete pad or pavers for your specified unit.
• Rubber pads (supplied with the unit) should be placed under the heat pump feet.
• The heat pump will produce water as moisture condensate forms on the evaporator coil. A drip tray or full size drain tray may be required to catch and pipe this water away.

Electrical

• Heat pumps must be permanently hard wired by a certified electrician.
• Requires an isolation switch installed within reach of the heat pump location. (Not to be mounted on the unit)
• Power supply cable must be suitably sized for the specific heat pump and its distance from switchboard.
• The specified Motor Rated circuit breaker must be installed for the heat pump.

 

Key notes of importance:

• Air Intake for the heat pump must not be restricted so a make up air grill sized for the specific model of heat pump is required in the plant room. Do not rely on manual openings (doors or windows) as they will get closed reducing the air flow causing poor performance/higher running costs.
• Cold air discharge must be ducted out of the enclosure to eliminate any chance recirculation.
• All clearances of the specific heat pump model must be maintained.
• Service accessibility should be taken into consideration as poor access can make service difficult and expensive.
• Adequate drainage measures should be in place to remove the condensate (water) build up.

Electrical

• Heat pumps must be “Hard Wired” by a certified electrician.
• Requires an isolation switch installed within reach of the heat pump location. (Not to be mounted on the unit)
• Power supply cable must be suitably sized for the specific heat pump and distance from the switchboard
• The specified Motor Rated circuit breaker must be installed for the heat pump.

We recommend looking at the Ducting and Drainage section for ideas and available equipment.

• Make sure filter pump is switched off before changing the position of any valves.
• If the filter is located below the water level of the pool close shut off valves if available; if shut off valves have not been fitted close pool skimmers and use “plumbers putty” to block any drain locations inside the pool.
• Cut a small section 100 to 200mm of the pipe section between the filter pool return and any chlorination device and plumb to and from the heat pump location making sure that the flow from the filter is connected to the “Water Inlet” on the heat pump and that the “Water Outlet” is connected to the pool return.
• This is to reduce the risk of any deterioration of plastic or rubber fittings and seals from chorine or other chemicals.
• All PVC pipe work should be clean and dry with all ends cut square and burrs removed.
• Ensure correct PVC pipe cement is used.
• Roughen all mating surfaces with emery tape and apply glue to both mating surfaces.
• While surfaces are still wet bring the two together using a twisting motion to ensure good fit and hold for approximately 30 seconds.
• Let glue dry for 24 hours before starting filtration pump.
• Before commissioning remove lid from top of heat pump and then turn on filtration system.
• Check that there are no water leaks from around heat exchanger or any of the PVC fittings and glue joints as this can cause major corrosion if left unattended.
• Also flow switch should be checked and adjusted if necessary.
  This is done by loosening the gland nut on the top of the flow switch and pushing the probe down just enough to stop the flap bouncing up and down.
  Re‐tighten gland nut.

1. Check water is flowing in the right direction.
2. Insert PVC pocketed reed switch with gland nut slightly loose.
3. Turn filter pump on.
4. Allow reed switch to lightly touch magnet then push reed switch down a further 6mm.
5. Tighten M16 Gland Nut.

1. Make sure the Titanium Sensor
   Pocket is fully inserted, so the tip is touching the PVC wall.
2. Tighten M16 Gland Nut
3. Insert the Temperature Sensor
   Probe, feeding it through so it
   stops at the bottom.
4. Use a small amount of silicon on the Sensor Probe Wires in the top of the Titanium Sensor Pocket to secure it in place.
5. Push the Plastic Cap into place.
6. Cable tie the Sensor Probe Wires
   around gland.

Electrical Installation must be completed by a certified electrician to meet local codes and standards. The cable size must be specified by the electrician for distance and Current Load of the specific model being installed and be wired directly from the distribution board by means of a circuit breaker or H.R.C fuse and. Caution: Low voltage can cause compressor damage An isolation switch is required and should be installed near the unit, preferably within reach of the heat pump location for ease of servicing.

For models HW650 through to HW3300 and most Dual Purpose units the flow switch and temperature sensor assembly is not pre‐installed, these items are supplied for onsite installation.

• Check the titanium sensor pocket and the temperature sensor probe are correctly secured in the temperature sensor assembly.
• Install the temperature sensor assembly on the water inlet of the heat pump, this can be located anywhere along the pipe work between the filter and the heat pump.
• Install the flow switch on the water inlet, ensure that it is positioned on the heat pump side of any shut off valves if used.
• When the plumbing has been completed turn the filter pump on and check the flow switch calibration.

For models HW650 through to HW3300 or if requested the controller, flow switch and temperature sensor assembly are supplied for onsite installation.

This requires a 4 core interconnection wire to be installed by the electrician.

The Flow switch and Temperature Sensor cables are supplied with 1.5m, these can be supplied at longer lengths 3m, 6m, 9m if requested at time of order.

The flow Switch and Temperature Sensor are wired to the Remote Control Box.

• Check the titanium sensor pocket and the temperature sensor probe are correctly secured in the temperature sensor assembly.
• Install the temperature sensor assembly on the water inlet of the heat pump, this can be located anywhere along the pipe work between the filter and the heat pump.
