Page 4: About Your Water Heater
Your Solahart air sourced heat pump water heater is designed for outdoor installation only. The water heater you have chosen is a 325 HAV model and is recommended for connection to a minimum 16 hour per day power supply. A Solahart heat pump water heater consumes less energy than an electric water heater. The impact on an electricity account will depend on the tariff arrangement of the water heater replaced and where you live. - Page 5 ABOUT YOUR WATER HEATER MAINS PRESSURE The water heater is designed to operate at mains pressure by connecting directly to the mains water supply. If the mains supply pressure in your area exceeds that shown on page 20, a pressure limiting valve must be fitted.
- Page 6 Warning: For continued safety of this water heater it must be installed, operated and maintained in accordance with the Owner‟s Guide and Installation Instructions. The Solahart warranty may not cover faults if relief valves or other safety devices are tampered with or if the installation is not in accordance with these instructions.
- Page 7 ABOUT YOUR WATER HEATER Notes: Power must be available at the water heater and to the heat pump for the LEDs to glow or flash. When power is turned on or reconnected to the water heater, the red LED will emit a solid glow for three (3) seconds and then extinguish.
- Page 8 Time of Use electricity supply due to a more expensive tariff rate applying. A timer will affect the operating times of both the heat pump circuit and the booster heating unit. Note: The 325 HAV model water heater is recommended for connection to a minimum 16 hour per day power supply.
- Page 9 At the end of the service life of the heat pump water heater and prior to the water heater being disposed of, a person qualified to work with refrigerants must recover the refrigerant from within the sealed system. The refrigerant must not be vented to atmosphere. Phone your nearest Solahart Dealer to arrange for an inspection.

Page 19: Installation
We recommend you provide advice to the system owner about their needs and building backup redundancy into the hot water supply system. The 325 HAV model water heater is recommended for connection to a minimum 16 hour per day power supply. - Page 20 INSTALLATION WATER HEATER LOCATION The water heater is suitable for outdoor installation only. The water heater should be installed close to the most frequently used outlet and its position chosen with noise, safety and service in mind. Make sure people (particularly children) will not accidentally touch the air inlet louvres and outlet grille and that they are clear of obstructions and shrubbery.
- Page 21 INSTALLATION TANK WATER SUPPLY If the water heater is supplied with water from a tank supply and a minimum water supply pressure of 200 kPa at the water heater cannot be achieved, then a pressure pump system must be installed to allow the heat pump circulator to operate and avoid air locks in the circuit.
- Page 22 INSTALLATION CIRCULATED HOT WATER FLOW AND RETURN SYSTEM A 325 HAV model heat pump water heater should not be installed as part of a circulated hot water flow and return system in a building. If a circulated flow and return system is required, it is necessary to bypass the heat pump water heater and install a secondary water heater connected to the hot water flow and return line and supplied from the heat pump water heater.
- Page 23 AS/NZS 3500.4. The insulation must be weatherproof and UV resistant if exposed. ANODE TYPES The vitreous enamel lined cylinder of the water heater is only covered by the Solahart warranty when the total dissolved solids (TDS) content in the water is less than 2500 mg/L and when the correct colour coded anode is used.
