MOUNTING THE UNIT

1) This unit should be mounted as close to the point of use as possible.

2) This unit must only be mounted in the vertical position with the water fittings located at the 

bottom of the unit. Mounting other than in the vertical position WILL cause element burn out.

3) The cold water inlet is on the right hand side and the hot water outlet is on the left hand side.

Under NO circumstances can these be reversed.

4) Leave a minimum of  8” above the unit for easy replacement of the elements.

5) This unit should be fixed to the wall using screws in the four mounting holes at each corner

of the backplate.

6) The unit should be installed in the plumbing system in such a way that there is no tendency

for the unit to be starved of water: for example: by an excessive draw-off of cold water just
before the unit. Also do not fit an unrestricted hot water draw-off point below  the heater as
this will tend to empty the heater by siphoning. 

NOTE

ALL MOUNTING AND PLUMBING MUST BE COMPLETE BEFORE YOU PROCEED

WITH ELECTRICAL HOOK-UP.

TEST THE INSTALLATION FOR LEAKS BEFORE CONNECTING THE 

ELECTRICAL SUPPLY.

7) It is possible that drawing off  water at comparatively high rates of flow elsewhere in the

building at the same time that the heater is working, could cause premature element failure.
Care should be taken not to starve the unit of water.  To prevent this from happening, open 
fully the main valve of the incoming water supply to the building and throttle back the 
control valves to the other water outlets.
