Installing the appliance
Plumbing
1 An isolating valve must be installed in the cold
water supply line to the heater.
2 Before connecting the water supply to the
appliance flush the pipe by running a quantity of
water into a bucket.
3 Remove the front cover by unscrewing the locking
screw behind the small lid.
4 Locate and break out the required holes and cable
inlets. Use the back-plate as a template to locate
the drilling positions and drill them with a 6mm bit,
ensuring there are no hidden cables or pipe-work.
5 Insert the rubber seal supplied and introduce the
connecting lead. When using a flexible cable it
must be secured, with the cable clamp provided,
on the rear of the appliance back-plate.
6 Screw the appliance into position using the
enclosed rawl plugs and screws.
7 Install the appliance vertically as per diagram. The
inlet and outlet are marked with arrows.
8 The water connections are designed for concealed or surface-mounted
installation and must be carefully sealed with a little PTFE tape when
screwed into the wall connections.
9 The front cover must be cleanly parted at the specified points for surface-
mounted installation or for direct connection to the pipes of the sanitary
fitting using the optional piping kit ZL001.
10 Open the water supply to the appliance and the tap to check all
connections for leaks.
11 Open and close the hot water tap several times until no more air emerges
from the tap and all air has been evacuated from the heater.
