SAFETY
This storage tank is supplied with a combination temperature pressure relief valve. When installed as
instructed in this manual, this valve has a rating of 575 kW. If the primary heating source has an output
exceeding this valve, additional relief valves are required. The valve(s) must not be tampered with or
removed. The storage tank and its primary heating source must not be operated unless each of these
devices is fitted and is in working order.
This storage tank is designed to be used in a closed circuit. Supplementary pressure relief devices such
expansion vessels, permanently venting the cylinder or using as a drain back solar system must be included
in the system design.
If a remote thermostat (Tankstat) is fitted to the storage tank and the electrical conduit is damaged, it must be
replaced by a qualified person in order to avoid a hazard. Phone Rheem Service or their nearest Accredited
Service Agent to arrange for an inspection.

for any reason. We recommend you seek advice from your plumber or specifier about your needs and
building back up redundancy into your hot water supply system.
