Installation Requirements

What’s Included

Your TDI heat pump package contains the main unit, up pipe temperature sensor, down pipe sensor, drain connector, drain pipe, rubber mounting blankets, protective hood, and installation manual.

Tools Needed

• Drill with hammer action capability
• 6mm masonry drill bit (for wall mounting)
• 12.5mm drill bit (for sensor installation)
• P-2 Phillips head screwdriver
• Power cable suitable for the unit capacity
• PVC piping, primer, and solvent
• Mounting hardware

Location Requirements

Critical Placement Guidelines:

The heat pump must be positioned at least 3.5 metres from the pool zone for electrical safety compliance. Install within 1.5 metres of your pool pump for optimal hydraulic efficiency. Mount the unit upright on a level, stable concrete surface 1 metre above ground level.

Clearance Requirements:

Maintain 500mm clear space on the sides and rear of the unit. Leave at least 1 metre clearance in front of the top discharge air outlet. Ensure adequate ventilation above the unit with no obstructions.

Environmental Considerations:

Avoid locations exposed to oil, flammable gases, corrosive products, or high-frequency equipment. Don’t install near roads where mud splashes could occur. Position away from windows and noise-sensitive areas. Keep out of reach of children.

Mounting the Unit

Foundation: The mounting surface must support the unit’s weight with a minimum capacity of 21g/mm². Use either the sheet metal foot mounting or the rubber blanket mounting method provided.

Drainage: Install the supplied drainage tube and connector at the bottom outlet to handle condensation water. The unit produces condensation during operation, so proper drainage is essential.

Installing Temperature Sensors

Up Pipe Sensor (Solar Panel Return):

Using the 12.5mm drill bit, create a hole in the pipe returning from solar panels. Insert the rubber grommet first, then push the temperature sensor through until firmly seated. Connect the sensor cable to the controller using the red bullet connectors provided.

Down Pipe Sensor (Pool Water):

Follow the same procedure for the pipe leading from the pool. Ensure both sensors are securely installed, and connections are watertight.

Plumbing Configuration

Important: The inlet and outlet unions cannot support the weight of flexible hoses. Connect only with rigid PVC piping to prevent damage to the internal titanium heat exchanger.

Keep the total pipe length between the pool and heat pump under 10 metres for optimal heating efficiency. Install isolation valves, bypass system, and drainage valves as shown in the installation diagrams.

System Configurations:

Stand-Alone System: The heat pump operates independently with its own dedicated pump. Plug the controller directly into a power outlet, then plug the solar pump into the base of the controller.

Integrated System: Works with existing pool equipment. Connect the chlorinator to the power outlet, the solar controller’s grey plug to the chlorinator, the filter pump to the grey connector, and the solar pump to the controller base.

Electrical Installation

Critical Requirements: This unit must be electrically connected following AS/NZS 3000 Wiring Rules by a licensed electrician.

The general electricity supply must include a 30mA differential switch (safety switch). Install an appropriately rated D-curve circuit breaker. Use outdoor-rated cable with correct specifications:

• TDI 13: 3G 2.5mm² (AWG 14)
• TDI 20: 3G 2.5mm² (AWG 12)
• TDI 26: 3G 4.0mm² (AWG 10)

Ensure proper earthing connections. For public installations, an emergency stop button is mandatory near the heat pump.

Third-Party Controller Integration

Adding a third-party pool automation controller is highly recommended. Connect to the L1 and N1 terminals on the power block. This allows integration without removing power plugs from pool pumps, which may void their warranty.

Common Issues

No Display: Check power supply connection, verify circuit breaker hasn’t tripped, and ensure all power cables are properly connected.

Pump Not Running: Confirm solar pump is plugged into the controller base. Check the current time is between 8:00 am and finish time (or use override to test). Verify panel temperature exceeds pool temperature by a differential amount.

Sensor Errors: Check red bullet connectors for secure fit. Look for corrosion or water in connections. Try swapping sensor connections to isolate the faulty sensor.

Frequent Cycling: May indicate differential setting too low, insufficient water flow, or air in the system. Verify the pump operates correctly, and the water flow meets specifications.

Maintenance

Regular Cleaning

Monthly: Clean the heat pump casing with a damp cloth only. Don’t use detergents or household chemicals, which can damage the surface coating.

Quarterly: Carefully clean the evaporator fins at the rear using a vacuum cleaner with a soft brush attachment. Remove leaves, debris, and dust buildup.

Annual Professional Service

A qualified technician should perform these checks yearly:

• Complete safety inspection
• Electrical wiring integrity
• Earthing connection verification
• Pressure gauge monitoring
• Refrigerant level check
• Overall system performance evaluation

Winterizing

When closing the pool for winter:

Power Off: Disconnect the electrical supply at the circuit breaker to prevent accidental operation.

Drain Water: Unscrew the inlet pipe water nozzle and let all water drain from the heat exchanger. Freezing water inside can crack the titanium heat exchanger, causing expensive damage not covered by warranty.

Protection: Cover the unit with the supplied hood to protect it from the weather when not in use.

Alternative: If ambient temperatures won’t drop below freezing, activate winter mode instead of completely draining. This keeps water circulating periodically without active heating.
