Installation: general guidelines
The relief valves are only to be used for relief dis-
charge purposes. No valves should be fitted between
the relief valves and the cylinder.
Indirect units and electrical wiring
On Indirect Units, where a coil is fitted to the cylinder, the supplied
two port motorized zone valve must be fitted in accordance with
the instruction details supplied for the appropriate installation.
Maximum working pressure of the coils is 3.5 Bar. All electrical
wiring to electronics, zone valve and immersion heaters must be
earthed and to current IEE Wiring Regulations.
Positioning the tundish
The tundish, which shows visible discharge from the relief valves, is
to be in a prominent, visible and safe position away from any elec-
trical devices. See discharge and safety devices on page 16.
Checking the P&T relief valve
The pressure and temperature relief valve is set at 7 bar and 90°C
and is factory fitted and sealed prior to dispatch. Whilst we en-
deavour to make sure there are no leaks from the seal, we would
advise checking the connection as the valve may have been dis-
rupted in transit.
Fitting the expansion vessel
The expansion vessel should be checked and if required charged
at 3.0 bar. The vessel should be mounted securely to the wall or
sufficient support with the fixing kit supplied. The connection
should be made between the vessel and monobloc kit.
The electrical supply to the controller and any addi-
tional immersion heaters must be installed by a quali-
fied electrician.
