MOUNTING THE UNIT

1) The 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) The heater should be fixed to the wall using all six mounting holes of the backplate.  Unit 

weight is approximately 45 lbs.  Use an appropriate fastener for this weight.  For the unit to be 
mounted against hollow walls, suggest using steel wall anchors, with the correct grip range 
and #6-32 screw size minimum.

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.

Hazardous Locations - Nonincendive Type Installation

1) The unit is mounted in an approved NEMA4 Enclosure.
2) Non-incendive for Class I, Division 2, Groups A, B, C&D.  Temperature class: T5 (212 °F)
3) As to installation, refer to  the National Electrical Code and NFPA 70. For locations C1, Div.2 

refer to section 501-4 (wiring methods) and 501-10 (utilization equipment) respectively.

Note: If ignition atmosphere is <T5 class, or if other classifications are required, another method of 

compliance would be “Purged and Pressurized”.  This is the process of supplying an enclosure 
with a protective gas at a sufficient flow and positive pressure to reduce the concentration of 
any flammable gas or vapor initially present to an acceptable level.  For further information, see 
ANSI/NFPA 496-1998, Purged and Pressurized Enclosures for Electrical Equipment.
