Page 4: Installation
INSTALLATION INSTALLATION STANDARDS The water heater must be installed: by a qualified person, and in accordance with the installation instructions, and in compliance with Standards AS/NZS 3500.4, AS/NZS 3000 and all local codes and regulatory authority requirements. In New Zealand, the installation must also conform with Clause G12 of the New Zealand Building Code. - Page 5 INSTALLATION Care must be taken during transportation and handling. Do not lay the heat pump module down and do not tilt the heat pump module or the heat pump and storage tank assembly more than 30° from the vertical. This will displace the compressor lubricating oil.
- Page 6 INSTALLATION FREEZE PROTECTION The water heater has a freeze protection system. The freeze protection system will protect the water heater from damage, by preventing ice forming in the waterways of the water heater, in the event of freezing conditions occurring. If the ambient air temperature falls below 1°C and the heat pump is not operating, the system will operate the circulator periodically.
- Page 7 The refrigerant must not be vented to atmosphere. Phone Rheem Service or their nearest Accredited Service Agent to arrange for an inspection.
- Page 8 The freeze protection system will be rendered inoperable if electrical power is not available at the water heater. Damage caused by freezing due to the unavailability of power at the water heater is not covered by the Rheem warranty. “Warranty Note” Refer to on page 40.

WATER SUPPLIES This water heater must be installed in accordance with this advice to be covered by the manufacturer’s warranty. This water heater is manufactured to suit the water conditions of most public reticulated water supplies. However, there are some known water chemistries which can have detrimental effects on the water heater and its operation and / or life expectancy. - Page 39 WATER SUPPLIES CHLORIDE AND PH Where the chloride level exceeds 250 mg/L the manufacturer‟s warranty does not apply to the water heater. In a high chloride water supply, the water can corrode stainless steel parts and cause them to fail. Where the pH is less than 6.0 the manufacturer‟s warranty does not apply to the water heater.
