Warning: Plastic liners must be in place for the water heater to function
properly. Do not remove or damage liners.
Warning: Do not use heat near plastic liners. Heat can be transferred
by conduction which may damage liners.
Water Inlet & Outlet Connections
An approved isolation valve and non return valve must be installed in the
supply line to the water heater.
A pressure limiting valve and expansion control valve may also be required
(for PLV requirements refer to “Water Supplies” on page 18 and for ECV
requirements refer to “Expansion Control Valve” on page 20).
A disconnection union must always be provided at the cold water inlet and
hot water outlet of the water heater to allow for water heater disconnection.
Left & Right Hand Side Water Connections – E80 ~ E400Models
All Aquamax mains pressure electric water heaters are manufactured with
dual inlets and outlets. For E80 ~ E400 models, the cold and hot water
supply can be connected to either side of the water heater. A kit containing
2 x ¾” brass plugs is supplied with the water heater to plug off the unused
cold and hot water supply fittings. When installing brass plugs, apply thread
sealing tape or an approved thread sealant to plug thread before
installation.
