Page 3: Foreword
A. Foreword Thank you for choosing the EZIHEAT high efficiency inverter pool heat pump. All EZIHEAT heat pumps are designed and built using the most advanced technology to the highest standards. Before attempting to install your pool heat pump please read and understand all the important information provided in this manual.
Page 4: Safety Precautions
B. Safety Precautions We have provided important safety messages in this manual for the installation, maintenance and repair on your heat pump. Please read, take note and obey all safety messages. Environment friendly R32 Refrigerant is used in this heat pump 1.
Page 5: Attention
Safety inspections must be carried out before maintenance or repair for heat pumps with R32 gas in order to minimise the risk. During installation of the heat pump if you notice any R32 gas leak stop the installation and call EZIHEAT on 1300 363 555 or your nearest service centre.

Page 10: Installation Guidance
D. Installation guidance 1. Installation reminder Only competent or professional persons are authorised to install the heat pump. All installations must be installed in line with the relevant building codes and standards of their current state or local governing body for all electrical, mechanical and water services to prevent danger or damage to the heat pump.
Page 11 b. Water pipe connection The inlet and outlet water unions must be plumbed in rigid pvc pipes. Flexible hoses must not be used DO NOT install water pipes in a way that they pass behind the heat pumps evaporator.
Page 12: Wiring
c. Typical installation diagram 1) The heat pump must be securely fixed with the use of the rubber feet (accessory), fixed by bolts (M10) to concrete foundation or fixed to walls by wall brackets. The concrete foundation must be solid and fastened; the bracket must be strong enough and antirust treated, 2) Do not stack substances that will block air flow near the inlet or outlet area, and there should be no obstruction within 50cm behind the heat pump, or the efficiency of the heat pump will be significantly reduced and could damage could occur.

Page 18: Testing
F. Testing 1. Inspect heat pump before use a. The air inlets and outlets are operating correctly and are free of debris and obstructions. b. It’s prohibited to install refrigeration pipe or components in corrosive environment. c. Inspect the electric wiring is correctly connected to the electrical schematic. d.
Page 19 G. Commissioning the heat pump Flow Rates The heat pump requires optimisation in order for it to achieve high efficiency and trouble free operation. For best performance the heat pump temperature difference between the inlet and outlet temperature should be between 2-3 degrees. Each heat pump has a minimum flow rate requirement, check the specification table to ensure the circulation pump in use is adequately sized.
Page 20: Maintenance
H. Maintenance “SWITCH OFF” power supply of the heat pump before cleaning, examination and repairing 1. In the winter season when the heat pump is not in operation for long periods of time, a. Switch off the power supply to prevent any machine damage. b.
