Installation / Operation Instruction Manual

GENERAL
This “Thermostatic” water heating unit is specifically designed to take in cold or pre-heated water and
heat it to temperatures suitable for domestic usage up to a maximum of 140°F (60°C). To obtain
optimum performance and energy savings. The unit should be located as near as possible to the point of
use.
The unit is supplied with compression rings and nuts suitable for direct coupling to standard 1/2” (5/8”
outside diameter) copper or plastic piping. There is no need for additional screwed fittings and under no
circumstance shall a blow torch be used on the pipe while the pipe is connected to the unit (serious
damage to the electronic flow switch will result).
Also, ensure that pipes are clear of installation debris before fitting to the unit.
THIS UNIT MUST HAVE ITS OWN INDEPENDENT CIRCUIT, USING CORRECTLY
RATED WIRES AND CIRCUIT BREAKERS. THE CIRCUIT SHOULD BE PROVIDED
WITH A “GROUND FAULT INTERUPTER” WHERE REQUIRED BY LOCAL, STATE
AND NATIONAL ELECTRICAL CODES.
MOUNTING THE UNIT
1) The unit should be mounted as close to the point of use as possible. For example, directly beneath a
sink is ideal. Do not install the unit above a faucet as a siphoning effect will drain the unit causing heating
element burn out.
2) This unit must only be mounted in a vertical position with the water fittings at the bottom of the unit.
Mounting other than in the vertical position WILL cause heating 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(as viewed
from the front of the unit). Under NO circumstances can these be reversed.
4) Leave a minimum of 8’’ ABOVE the unit for easy replacement of the heating element.
5) The unit should be fixed to the wall using screws in the four mounting holes at each corner of the
backplate.
NOTE: The unit should be installed below the level of all hot water outlets serviced by this unit.
NOTE: PRESSURE AND TEMPERATURE RELIEF VALVE
This unit is not required to have a Pressure and Temperature safety relief valve(PTPV). Consult
local codes to find out if one is required in your area. If local codes require the use of a
temperature and pressure valve one should be installed on the hot water outlet pipe, before the
ball valve
FAILURE TO GROUND THIS UNIT MAY RESULT IN DEATH OR SERIOUS INJURY
