Installation [All Models]
a) POSITIONING THE UNIT
The heater should be positioned in a convenient
place, on a wall that is capable of supporting it
safely (refer to table above for weight of boiler).
Use the mounting template and fitting kit provided.
Position the boiler so that the tap is approximately
400mm above a draining board. Leave sufficient
space around the unit to enable access for servicing,
paying particular attention to the position of the
top-centre fixing screw that holds the case in place.
When mounting on wall…screw in the top two
screws leaving about 6mm protruding and hang the
machine using the keyhole slots provided. Once the
machine is positioned, tighten the top screws and
insert the bottom screw.
b) ELECTRICAL CONNECTION
The circuit should be protected by its own 13amp
double-pole connection unit with flex outlet to
BS5733, alternatively the circuit should have a means
of disconnection incorporated in fixed wiring, having a
contact separation of at least 3mm in all poles.
Minimum cable size is 1.5mm
2
. The use of an
ELCB is recommended.
• WARNING: This appliance must be earthed.
• Electrical installation should conform to current
I.E.E. wiring regulations.
• When using fixed wiring, the bare section of earth
must be sleeved to within 8mm of the end.
• Only a qualified electrician should carry out
this work.
BASE ENTRY OF CABLE:
Use the cable gland.
Loosen cable-gripping nut and pass cable through
gland, leaving enough free cable to connect to
terminal block. Tighten cable gland grip nut.
Alternative Rear Entry Installation (Electrical):
The fixed or flexible cable is connected direct to the
terminal block – the cable gland is not utilised.
DO NOT SWITCH ON UNTIL THE INSTALLATION IS
COMPLETE AND THE CASE AND TAP ARE IN PLACE
c) WATER CONNECTION
NOTE: Although it will not harm the boiler, it should
not be operated with the water supply turned off.
The water supply must have a pressure not
exceeding 7 bar and no lower than 2 bar.
If the mains water pressure is below 2 bar
a fault situation could arise.
