I.  MOUNTING THE UNIT

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

Do not 

install the heater above a faucet or “point of use” because the siphoning effect may  

drain the heater which can cause premature element burn out.  If the unit must be installed at      
a higher elevation, you must install spring loaded check valves on both the inlet and outlet of 
the water heater.

2) This unit must only be mounted in a vertical position with the 

water fittings positioned at

the bottom of the unit

. Mounting other than in the vertical position 

will

cause element burn 

out and permanent damage to the water heater.

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

as marked by the fittings of the unit.  Under 

NO

circumstances can these be reversed.

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

5) The heater should be fixed to the wall using

all 

four mounting holes of the backplate.  

Use an appropriate fastener for the weight.  For the unit to be mounted against hollow walls,
we suggest using steel wall anchors with the correct grip range, and #10-32 screws at a
minimum.

NOTE: The heater should be installed 

below

the level of all hot water outlets serviced by this

NOTE: The heater should be installed 

below

the level of all hot water outlets serviced by this

heater.  Otherwise install spring loaded check valves on both the inlet and outlet.

NOTE: PRESSURE AND TEMPERATURE RELIEF VALVE

These units are not required by UL to have a Pressure and Temperature Relief
Valve (PTRV). You should check with local codes to find out if one is required in your
area.  If local codes require the use of a temperature and pressure relief valve it
should be installed on the outlet hot water pipe before the outlet ball valve.
