WATER CONNECTION (Refer to Fig.1)
Mount the water heater in the desired position in accordance with the above
requirements. The Float Valve, Overflow fitting, Dip Tube and Screened Vent
are supplied loose within the cistern tank. Remove the cistern cover,
assemble the Float Valve body, arm and float. The Float Valve can be
mounted on either the left or right of the heater by cutting a suitable hole
using the pre-punched holes in the outer case as a guide. Use a sharp hollow
punch, hole saw or cutter and ensure the hole edge is clean and free from
notches and swarf. Secure Float Valve to the cistern tank wall. NOTE washer
should be between valve body and cistern wall, secure by tightening backnut
on outside of heater. The Overflow fitting can also be mounted on the left or
right by drilling the appropriate position as for the Float valve.Attach the
Overflow fitting with the filter screen housing to the outside of the heater, the
washer and backnut should be assembled from inside the cistern tank. The
Dip Tube should be pushed into the Overflow fitting inside the cistern tank
such that the lower edge of the tube will be immersed when the cistern is
filled with water. The Screened Vent should be snapped into the prepared
hole in the cistern cover, when fitting support the material around the hole to
avoid damaging the cover.
The Float Valve is suitable for inlet pressures up to 7bar (100 p.s.i.), therefore
it is recommended that the cold water supply is taken from the mains. For
higher pressures the float should be replaced by one of 6" diameter. The Float
Valve is threaded 1/2.BSP (for 15mm pipe).
The Overflow is fitted with a mesh screen to prevent the ingress of insects.
The connection to the overflow pipe is 22mm compression for 22mm o/d pipe.
The overflow pipe must be laid to a continuous fall and terminate in a position
where it can be readily seen.
