Pipe assembly for offset installation
Use this pipe assembly if you intend to offset the appliance by up
to 90mm downwards from the water connection.
Pipe assembly for replacing a gas water heater
You will need this pipe assembly set if the existing installation
has gas water heater connections (cold water connection on the
left-hand side, DHW connection on the right-hand side).
Pipe assembly for DHB water plug-in couplings
Use the water plug-in couplings if the existing installation contains
water plug-in connections from a DHB water heater.
Load shedding relay (LR 1-A)
The load shedding relay for installation in the distribution board
provides priority control for the instantaneous water heater when
other appliances, suchas electric storage heaters, are being op-
erated simultaneously.
Central thermostatic valve (ZTA3/4)
Use the thermostatic valve for central premixing, for example
when operating an instantaneous water heater with preheated
water. For use in shower operation, the valve must be set to a
maximum of 55°C.
