with the National Plumbing Standard AS/NZS 3500.4 and local authority 
requirements.

WATER INLET AND OUTLET 
All pipe work must be cleared of foreign matter before connection and purged 
before attempting to operate the water heater. All olive compression fittings 
must use brass or copper olives. Use thread sealing tape or approved thread 
sealant on all fittings. 
 
An isolation valve and non return valve must be used on the cold water line to 
the water heater. A non-return valve must be fitted on the cold water supply to 
this water heater in compliance with Clause 5.9.1 of AS/NZS 3500.4. Due to 
the higher temperatures generated by solar water heaters, an additional 
effective back-flow prevention device also should be fitted as an extra 
safeguard. Valve manufacturer RMC recommends Dual Check Valve No 
N7150, as being suitable for this application.
