WATER INLET AND OUTLET
All pipe work must be cleared of foreign matter before connection and purged
before attempting to operate the water heater. All olive compression fittings
must use brass or copper olives. Use thread sealing tape or approved thread
sealant on all fittings.
An isolation valve and non
return valve must be installed
on the cold water line to the
water heater. An acceptable
arrangement is shown in the
diagram. Refer also to
on page 25 and
to
on
page 23.The solar hot and solar
cold pipe connections are
shown on page 40.
A disconnection union must always be provided at the cold water inlet and hot
water outlet on the water heater to allow for disconnection of the water heater.
This solar storage tank has either a plastic
dip tube or fitting liner in the inlet and outlet
fittings (see diagram). These must be in
place for the water heater to function
properly. Do not remove or damage them
by using heat nearby. They will be pushed
into the correct position as the fitting is
screwed in.
