Cold water connection: R¾/20.
(cold water inlet to tank: RP¾/20).

Solar hot (from collector) connection:
DN15 compression fitting.

Solar cold (to collector) connection:
DN15 compression fitting.

Relief valve connection: RP½/15.

Bleed valve connection: G1.0B.

Expansion control valve connection (when fitted): RP½/15.

INLET/OUTLET CONNECTIONS
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.

All water heaters have 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.

A non return valve must be installed on the cold water supply pipe to the solar
storage tank. Use the arrangement shown in the installation diagram (refer to
page 21). The plumbing arrangements for the cold water inlet and solar cold and
hot pipes are shown on page 26. The pipe work must be cleared of foreign matter
before connection and purged before attempting to operate the water heater.

PIPE SIZES
The solar cold and hot pipes between the solar storage tank and the solar
collectors should be a minimum DN15. The cold water pipe to the water heater
should be the same size or bigger than the hot water line from the water heater. For
best results, choose the most suitable pipe size for each individual application.
Refer to the relevant plumbing regulations.
