Installation Manual - Roof Mount Solar Hot Water - August 2017
Trouble Shooting
SOURCE
Tempering Valve installed
Electric or gas booster is not
turned on or not configured
correctly
Pressure Temperature
Relief Valve (PTR) /
Expansion Control Valve
(ECV) where applicable.
Pressure Reduction Valve
(PRV)
SOLUTION
A tempering valve must be installed on every
solar hot water system. Tempering valves will
mix water down to 50°C.
Electric booster should be set to at least 60°C.
Ensure circuit breaker is switched on. Ensure
power is switched on to gas booster. Ensure
mains gas supply hasn't been isolated.
An 850kPa and 99°C PTR valve is used on the
iHeat water tank, which is located on the side
of the water tank and is essential for its safe
operation. The PTR valve is designed to allow
3-5% of total tank volume to discharge during
heating to allow for hot water expansion.
A pressure reduction valve has been installed
to limit the inlet pressure to your new iHeat
Water Heater. This device regulates the
incoming pressure & increases life of the
cylinder. This device will also protect your
cylinder if the mains pressure is increased by
the local water authority.
