14 | Electrical connection

NOTICE:
This drain pipe must fall continuously, shall
be left open to the atmosphere, and shall be
in a frost free environment
WARNING:
Relief valve easing gear should be checked
and operated AT LEAST ONCE EVERY SIX
MONTHS.
If water does not discharge freely when the
lever is operated, the valve should be
checked by an authorised agent.
WARNING:
The relief valve and relief valve drain pipe
must not be sealed or blocked. Small
amounts of water may leak from the relief
valve during heating cycles.
WARNING:
Relief valves should be replaced at intervals
not exceeding 5years, or more frequently in
areas where water quality is poor
WARNING:
The function of the PTR valve is to discharge
high temperature water under certain
conditions. Therefore it is strongly
recommended that the pipe work connected
to the PTR valve is able to withstand water
temperatures exceeding 99 °C. Failure to
follow this recommendation may result in a
dangerous situation
Connect the outlet of the PTR valve to a suitable open drain so
that the discharge water cannot contact any electrical parts,
persons or animals, and to eliminate any other possible risks.
The drain line from the PTR valve must comply with the
requirements of AS/NZS 3500.4.
Always use a PTR valve of the same rated pressure and
temperature as the PTR Valve supplied with the unit.
