GENERAL

This heater must have its own independent circuit, using

a correctly rated breaker and

wires suitable for at least 75 oC operation.

Failure to ground this system may result in death or serious injury.

1) 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 at the top of the unit. Mounting other than in the vertical upright
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” below the unit for easy replacement of the
element.

5) The heater should be fixed to the wall using the four mounting holes at
each corner of the backplate.

NOTE: The heater should be installed below the level of all hot water
outlets serviced by this heater.

NOTE: PRESSURE RELIEF DEVICE
This unit is not required by UL to have a Pressure and Temperature
safety 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 temperature and pressure relief valve it
should be installed on the outlet hot water pipe before the outlet ball valve.

TROUBLE SHOOTING

SYMPTOM: NO HEAT INDICATOR LIGHT OFF

1) ELECTRIC SUPPLY IS OFF
Turn on the main breaker.

2) NO OR LOW WATER FLOW
Ensure that the minimum flow rate to switch on your heater is met.
Models minimum flow rate = 0.75 gallons per minute
“SP8208, 80, 90, 100, 75, 95”
Models minimum flow rate = 0.6 gallons per minute
“SP60,65”
Models minimum flow rate = 0.5 gallons per minute
“SP2412, 3012, 3512, 3208, 4208, 3277, 4277, 35, 55”
Also check that the inlet filter screen is clear from any debris. This is
located in the brass inlet boss.

3) WATER CONNECTIONS ARE REVERSED
The correct plumbing configuration is
Cold water inlet = right side, hot water outlet = left side.

4) ELEMENT BURNED OUT
TURN OFF THE breaker!
Using an ohmmeter test the resistance of the heating element
across the two threaded termination rods on top of the element.
The resistance reading should be under 10 ohms.
If the resistance is much greater than this value, call Eemax for
a replacement element.

5) ECO TRIPPED (High Limit Thermostat)
TURN OFF THE FOUR MAIN CIRCUIT BREAKERS!
Reset by pushing in red button on each heater module.

SYMPTOM: NO HEAT OR LOW TEMPERATURE WITH
INDICATOR LIGHT ON

1) WATER FLOW TOO HIGH
Reduce the water flow by using an outlet ball valve. See page 3
for temperature rise at various flow rates.

2) INCORRECT POWER SUPPLY
Make sure that the unit is connected to the voltage supply specified
on the rating label on the the front cover of the unit and no other.

3) ELEMENT BURNED OUT
TURN OFF THE breaker!
Repeat the steps from paragraph 4 above.

The Eemax “Single Point” heater is specifically designed to be installed
“under sink” feeding a SINGLE faucet(5.5kW and lower) It is designed to
take in cold water ONLY and heat it to temperatures suitable for hand washing.
To obtain optimum performance and energy savings, the unit should be located
as near as possible to the point of use. The heater incorporates a constant
flow device and should only be used with the faucet aerator supplied with this
heater by Eemax. The unit is supplied with compression rings and nuts suitable
for direct coupling to 3/8” copper or plastic piping. Do not use additional screwed
fittings or pipe dope. Doing so will void the warranty. DO NOT SOLDER PIPES
WHILE THE UNIT IS INSTALLED/ DO NOT USE PIPE DOPE OR TEFLON TAPE
(serious damage to the electronic flow switch will result).
