PLUMBING CONNECTIONS
1) The unit is supplied with 3/8’’ compressionfittings.USE THESE: DO NOT
USE THREADED PIPE FITTINGS. DO NOT USE PIPE DOPE OR TEFLON
TAPE ON THIS INSTALLATION.Ensure the inlet filter supplied with thisunit
is in place.
2) Ensure that the pipes are correctly aligned with the inlet and
outlet bosses to avoid excessive stress on the heater body molding of the
unit.
NOTE: Run water through the supply pipe to remove all debris from the
pipe before connecting to the unit. Failure to do so could damage the flow
switch.
3) Install isolating valves (shut-off type),or equivalent on both inlet and outlet
pipes. This allows the unit to be isolatedfor maintenancepurposes. (Fig. 2)
4) Whenall plumbing is complete, inspect the system for water leaks
at all plumbingconnections. If a water leak is present take corrective action.
If a water leak is at the compressionfitting, slowly tighten compressionnut
until the water leaks ceases.
Fully open both inlet and outlet shut-off valves.
Run all hot water outlets fed by this heater one at a timeuntil thewater flow
is continuous and free from “gulping”and all visible air pockets.
NOTE:
ALL PLUMBING AND MOUNTING MUST BE COMPLETED
BEFORE PROCEEDING WITHTHE
ELECTRICAL HOOK-UP.
TEST THE INSTALLATION FOR LEAKS BEFORE
CONNECTING THE ELECTRICAL SUPPLY.

GENERAL
This “Single Point”water heating unit is specificallydesigned to be installed
“under sink”feeding a SINGLE faucet. This unit is designed to take in cold water
ONLY and heat it to temperaturessuitable for hand washing. To obtain optimum
performance and energy savings, the unit should be located as near as possible
to the point of use. This unit incorporatesa constant flow device and shouldonly
be used with the faucet aerator supplied.The unit is supplied with compression
rings and nuts suitablefor direct coupling to 3/8”copper or plastic piping. Do not
use additional screwed fittingsor pipe dope. The use of such materials will void
the warranty. DO NOT SOLDER PIPES WHILE THE UNIT IS INSTALLED
(serious damage to the electronic flow switch will result).
INSTALLING THE UNIT
1) The unit must be mounted underneath a sink in a VERTICAL position with
the inlet and the outlet at the TOP. Mounting in any way other than this
WILL cause element burn out and possibly damage the unit further.
Do not install this unit above the faucet as the siphoning effect will drain
the heater which can cause element burn out and damage the unit.
2) 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.
3) Leave a minimum of 8”below the unit for easy replacement of the
element.
4) This unit should be fixed to the wall using the four mounting holes at
each corner of the backplate.
THIS HEATER MUST HAVE ITS OWN INDEPENDENT CIRCUIT, USING A
CORRECTLY RATED CIRCUIT BREAKER AND WIRES SUITABLE FOR AT
LEAST 75 OC OPERATION.
WARNING
UNIT MUST BE PROPERLY GROUNDED TO THE “GND”LOCATION
ON THE TERMINAL BLOCK. FAILURE TOGROUNDTHE SYSTEM MAY
RESULT IN SERIOUS INJURY OR DEATH.

WARNING
BEFORE BEGINNING ANY WORK ON THE ELECTRICAL INSTALLATION BE SURE
THAT THE CIRCUIT BREAKER IS IN THE “OFF”POSITION TO AVOID ANY
DANGER OF ELECTRICAL SHOCK.

RATINGS OF ‘’SINGLE POINT ”MODELS
* Units must be installed at rated voltage ONLY
THIS HEATER MUST BE INSTALLED ONLY IN A VERTICAL POSITION
WITH THE INLET AND OUTLET AT THE TOP
ELECTRICAL CONNECTIONS
This water heating must have its own independent circuit using
insulated, UL listed, 3 wire cable of the appropriatesize suitable
for use up to 75°C protected by the correctly rated circuit breaker.
WARNING
Unit must be properly grounded to the “GND”locationon the terminalblock.
Failure to ground the system may result in serious injury or loss of life
Wire entry into the unit should be made throughthe lower right hand corner of the
backplate via one of the two “knockout”holes provided.
The “mains”wires should be connected to the slots in the terminalblock marked
L1 and L2 (N). The ground lead must be connected to the slot marked
Failure to ground the system may result in death or serious injury.
WARNING
