WATER INLET AND OUTLET
All pipe work must be cleared of foreign matter before
connection and purged before attempting to operate the
storage tank. All olive compression fittings must use brass
or copper olives. Use thread sealing tape or approved
thread sealant on all fittings.
HEAT TRAP
An external heat trap is required be installed. The heat trap
is to be within one (1) metre of the hot water outlet, before
the first hot water branch and have a vertical drop of
250 mm from the outlet of the water heater.
PIPE SIZES
The pipe sizing of hot water supply systems for commercial installations should be carried out by persons
competent to do so, choosing the most suitable pipe size for each individual application. Reference to the
technical specifications of the primary heating source, storage tank and local regulatory authority
requirements must be made.
TEMPERATURE PRESSURE RELIEF VALVE
The temperature and pressure relief valve is shipped with the tank. It comes in a separate box that contains,
the TPR, NPT to BSP adaptor, tundish and thermostat well. The temperature pressure relief valve must be
fitted before the storage tank is operated. Before fitting the relief valve, make sure the probe has not been
bent. Seal the thread with an approved thread sealant such as Teflon tape - never hemp. Make sure the tape
does not hang over the end of the thread.
Screw the valve into the correct opening
drain pointing downwards. Do not use a wrench on the valve body - use the spanner flats provided. A copper
drain line must be fitted to the temperature pressure relief valve (refer to
