MODEL NUMBERS COVERED

GENERAL

The Eemax “Series Three” water heater is specifically designed to take in

cold or pre-heated water and heat it to temperatures suitable for emergency equipment,

With a maximum output temperature of 180°.

To obtain optimum performance and energy savings, the unit should be located as near as possible

to the point of use. The unit must only be installed in a vertical position with the inlet

and outlet at the bottom. The power is activated by individual electronic flow switches located

in each of the twelve heating modules. These will be damaged by excessive heat, do not solder

any pipes that are in contact with the heater.

Also ensure pipes are clear of installation debris before fitting the heater, otherwise the flow

switches could jam in the “on” position. The unit must be connected to its own individual electric

circuit protected by a suitably rated three pole breaker. The maximum voltage which can be

applied across any heating module is 480 volts.

WARNING

Improper installation, adjustment, alteration, service or maintenance can cause DEATH,

SERIOUS BODILY INJURY OR PROPERTY DAMAGE. Refer to this manual for

assistance or consult the local electric utility for further information.

The unit is supplied with 1/2” compression water fittings.

Under no circumstances use a blow torch on pipe which is connected to the heater (serious

damage to the electronic flow switch will result). Carefully use Teflon tape, ensuring no

debris enter the heater. Do not use pipe dope.

WARNING

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

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 WILLcause 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 4 mounting holes of the backplate. Unit

weight is approximately 15 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 ELECTRICALSUPPLY.

Hazardous Locations -Nonincendive Type Installation

1) The unit is mounted in an approved NEMA4 Enclosure.

2) Non-incindive for Class I, Division 2, GroupsA, 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/NFPA496-1998, Purged and Pressurized Enclosures for Electrical Equipment.

1) The unit is supplied with NPT fittings., USE THESE; DO NOT USE PIPE DOPE AND DO

NOT SOLDER PIPE TO THE INLET OR OUTLET.

2) Take care to ensure that the pipes are correctly aligned with the inlet and outlet bosses in

order to avoid excessive stress on the heater manifold.

NOTE: When soldering pipe joints remove heater from the wall. Serious damage can occur

if any soldering is done while pipes are connected to the heater.

Run water through the supply pipe to remove all debris from the pipe before connecting the

heater. Failure to do so could cause damage to the flow switch.

3) Install isolating valves (full flow ball valve type) on both inlet and outlet pipes. This allows

unit to be isolated for maintenance purposes. (see Fig. 1)

4) When all plumbing is complete, fully check the system for water leaks at all plumbing

connections. If leak is present take corrective action. Fully open both inlet and outlet

ball valves. Run all hot water outlets fed by this heater one at a time for a minute or two

until the water flow is continuous, free from ”gulping” and from all visible air pockets.

PLUMBING HOOK-UP

NOTE

ALL MOUNTING AND PLUMBING MUST BE COMPLETE BEFORE YOU PROCEED

WITH ELECTRICAL HOOK-UP.

WARNING

HAZARD OF ELECTRICAL SHOCK! BEFORE BEGINNING ANY WORK ON THE

INSTALLATION, MAKE SURE THE ELECTRICALSUPPLY TO THE HEATER IS TURNED

“OFF”. FAILURE TO DO THIS COULD RESULT IN DEATH, SERIOUS BODILY INJURY,

OR PROPERTY DAMAGE.

WARNING

WATER HEATERS EQUIPPED FOR ONE VOLTAGE ONLY: CHECK THE RATING PLATE

ON THE FRONT OF THE UNIT. DO NOT USE THIS WATER HEATER WITHANY VOLTAGE

OTHER THAN THE ONE SHOWN ON THE MODEL RATING PLATE. FAILURE TO DO SO

CAN RESULT IN DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. IF YOU

HAVE ANY QUESTIONS OR DOUBTS CONSULT YOUR ELECTRIC COMPANY.

This heater must have its own independent circuit using four wires; three live and one ground,

of the appropriate rating protected by the correctly rated three pole breaker

WARNING

FAILURE TO GROUND THE SYSTEM MAY RESULT IN DEATH OR SERIOUS INJURY

IMPORTANT

BEFORE SWITCHING “ON” THE POWERAT THE MAIN CIRCUIT BREAKER PANEL MAKE

SURE THAT THE HOT WATER CIRCUIT IS FREE OF AIR POCKETS OR PREMATURE

FAILURE OF THE ELEMENT WILL OCCUR. TO DO THIS OPEN ALL HOT WATER OUTLETS

ONE AT A TIME FOR A MINUTE OR TWO UNTIL THE WATER FLOW IS CONTINUOUS AND

FREE FROM “GULPING”AND FROM VISIBLEAIR POCKETS.

COMMISSIONING YOUR HEATER

IMPORTANT

Before switching “on” the power at the main circuit breaker panel make sure that the hot

water circuit is free of air pockets or premature failure of the heating element will occur.

To do this open all hot water fixtures one at a time for several minutes until the water flow

is continuous and free from “gulping” and from visible air pockets.

1) With inlet and outlet BALL VALVES fully open, turn on a hot water outlet.

2) Run for 3 minute.

3) Switch on electric supply at circuit breaker panel.

4) The power indicator lights should now come on.

NOTE: At this point water temperature may not be hot.

5) Using the OUTLET BALL VALVE slowly reduce water flow until desired temperature is

achieved at hot water outlet.

NOTE: The water temperature is regulated by the flow through the heater. The lower the

flow the higher the temperature and vice versa.

6) If water does not achieve desired temperature, please call technical services.

TROUBLESHOOTING

SYMPTOM: NO HEAT INDICATOR LIGHT OFF

1)ELECTRIC SUPPLY IS OFF

Turn on the main circuit breaker.

2)NO OR LOW WATER FLOW

Ensure that the minimum flow rate to switch on your heater is met, for this figure

refer to the front cover of this manual.

Also check that the inlet filter screen is clear from any debris.

3)WATER CONNECTIONSARE REVERSED

Cold water inlet = right side, hot water outlet = left side.

4)ELEMENT BURNED OUT

TURN OFF THE MAIN BREAKER!

Using an ohmmeter test the resistance of the heating element across the two

threaded termination rods on top of the element.

See the front cover of this manual for the correct value.

If the resistance is much greater than the correct value, call your supplier for a

replacement element.

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 5 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 front cover of the unit and no other.

3)ELEMENT BURNED OUT

TURN OFF THE MAIN BREAKER!

Repeat the steps from paragraph 4 above.

4)THERMOSTATADJUSTMENT SCREW NOT TURNED UP

Turn the thermostat adjustment screw clockwise in small increments until the

indicator light remains on. Take care not to force the screw past it’s stop

position.
