INSTALLATION Refer to Fig.1 & 2
2.1
The heater should be securely fixed in position & all terminal connections checked for tightness before
energising.
2.2
The unit must be wall mounted allowing one metre above the highest draw off point to ensure good flow.
2.3
Do not mount heater too high on wall. To avoid splashing, the end of the swivel outlet should be
approximately 150mm above top of sink.
2.4
Screw in two top mounting screws only & hang heater on these. Mark position of third fixing hole through
bottom mounting bracket & then secure heater to wall, see fig 2 for details.
2.5
Always ensure that the wall is sufficiently strong to carry the weight of the unit when it is full of water.
3.0 PIPEWORK
CONNECTIONS
3.1
The installation must conform to any local authority byelaws.
3.2
Before proceeding to next operation remove heater base cover. Unscrew captive screw in base cover & slide
base cover forward for removal.
3.3
The heater is suitable for connection to standard water supply.
3.4
With inlet valve fully open flow through heater is best limited to a flow rate of 6 litres/min.
3.5
An isolating valve must be fitted to the cold water mains supply to allow for servicing.
3.6
Ensure that valve inlet & outlet are free from any obstructions such as packing materials. Connect to heater
inlet pipe marked with blue arrow, by means of the coupling nut & olive supplied.
3.7
Do not screw inlet valve down hard. Water always expands when heated, & therefore, a small amount of
water will drip from the swivel outlet for a short while after use.
3.8
To attach swivel outlet ensure that the inlet & outlet are free from any obstructions & that the ancillary parts
are present. Fit coupling end of swivel outlet up into outlet pipe, tighten nut but allow swivel outlet to move
smoothly.
3.9
Important warning
- the outlet acts as a vent & under no circumstances must any other swan-necks, pipe-
work outlets or fittings be connected to the heater outlet other than a genuine supplied or approved fitting.
