INSTALLATION GUIDE AND OWNER’S

MANUAL

“SINGLE POINT”, “FLOW CONTROLLED” and “THERMOSTATIC”

ELECTRIC INSTANTANEOUS WATER HEATERS

BEFORE ATTEMPTING ANY INSTALLATION, MODIFICATION OR SERVICE OF THIS

HEATER, MAKE SURE THE ELECTRICAL POWER IS DISCONNECTED.

Read and understand these instructions thoroughly before attempting the installation or service of this
water heater. Failure to follow these instructions can result in serious injury, death and/or property
damage. The warranty of this water heater will depend upon the proper installation according to these
instructions. Some heaters come supplied with separate faucet aerators. If supplied, the aerator must
be installed in the faucet for optimum performance. This heater must be used to heat water only and
be in a location where it is not subject to freezing temperatures. The manufacturer is not liable for any
damages resulting from improper installation or misuse.

This installation must conform to the latest requirements of the National Electrical Code and all
applicable state and local codes. This information is available through your local authorities. You must
understand these requirements before beginning this installation.

This unit is not required by UL 499 to have a Temperature and Pressure relief valve (T&P). You should
check with local codes to find out if one is required. If it is, it must be installed in the outlet hot water
pipe between the heater and the isolation valve.

IMPORTANT SAFETY INSTRUCTIONS

When using this electrical equipment, basic safety precautions should always be followed, including the
following:

READ AND FOLLOW ALL INSTRUCTIONS

A green terminal (or a wire connector marked “G”, “GR, “Ground”, or “GROUNDING”) is provided within

the control box. To reduce the risk of electric shock, connect this terminal or connector to the
grounding terminal of the electric service or supply panel with a continuous copper wire in accordance
with your local electrical code.

(Canadian Installations Only) Connect only to a circuit protected by a Class A
ground fault circuit interrupter. Attention: Brancher uniquement à un circuit protégé par un disjoncteur
de fuite de terre de Classe A.

(Canadian Installations Only) Do not install in a bath enclosure or shower stall or
connect to a salt-regenerated water softener or a water supply of salt water. Attention: Ne pas installer
dans une baignoire ou une cabine de douche et ne pas brancher à un adoucisseur d’eau régénéré avec
du sel ou à un approvisionnement en eau salée.

(Canadian Installations Only) Use copper conductors only. Use bonding conductor in accordance with
the Canadian Electrical Code Part I. Utilisez dez conducteurs en cuive uniquement. Utilisez des
conducteurs de mize à la masse conformement au Code Canadien de L’Électricité, Partie I.

SAVE THESE INSTRUCTIONS

GENERAL

The Eemax “Single Point” or “SP”, “ Flow Controlled” or “EX” and “Thermostatic” or “EX-T” heaters will
provide optimum performance and energy savings when located under the sink and as close as possible
to the point of hot water use. For best performance the heater should be BELOW the point of use.
Failure to do so may void the warranty. Contact your Eemax representative for further information.

“Single Point” heaters and “Flow Controlled” heaters are to be plumbed to a cold water source ONLY
and heat it with a temperature rise at flow rates as shown on the table on page 10.

“Thermostatic” heaters are the only heaters of the three outlined in this manual which have
thermostatic control. “Thermostatic” heaters accept cold or preheated water and heat it to
temperatures suitable for normal domestic usage up to a maximum of 140 degrees F. With the “S”
option, they can be used as a temperature booster for sanitation applications sometimes required for
dishwashers in commercial kitchens. Units built with the “ML” option are factory-set to a maximum
temperature of 110°f and are recommended for hand washing applications. The “ML” option is an
excellent choice for supplying hot water to sensor-type or metering faucets.

1) The heater should be mounted “under the sink” as close to the point of use as possible. “Single

Point” will have the brass fittings on the top pointing “up”. “Flow Controlled” and “Thermostatic” will
have the fittings on the bottom pointing “down”.

2) The fittings must be pointed in
the vertical direction and be at
least 16 inches below the level of
the hot water faucet. Make sure
to leave a minimum of 8 inches
service clearance at the end
OPPOSITE the fittings.

3) Remove the cover and fasten to
the wall using the four mounting
holes at each corner of the back

plate. Make sure the “UP” arrow
on the circuit board is facing “UP”.

Replace the cover.

This heater must be installed in a location where it is not subject
to freezing temperatures.

1) MOUNTING THE UNIT TO THE WALL

3 EX07200-13 Rev C

1) The heater’s cold water INLET is on the

“RIGHT” and the hot water OUTLET is on the
“LEFT”. Install full flow ball valves to the inlet

and outlet pipes and run water through the inlet
pipe into a bucket to purge it of any debris.
Close the inlet ball valve.

2) Make sure the inlet filter screen is present in
the inlet fitting and the inlet and outlet pipes
are correctly aligned with the heater
connections to minimize stress on the heater.

2) PLUMBING HOOK-UP

The heater is supplied with brass compression fittings that are compatible with either copper or plastic
pipe. “Single Point” has 3/8” fittings. Both “Flow Controlled” and “Thermostatic” units have ½” fittings.
Make sure these fittings are used for this installation. Contact your Eemax representative for further
information.

NEVER SUBSTITUTE THREADED PIPE FITTINGS USING PIPE DOPE OR TEFLON TAPE

AND NEVER SOLDER ANY PIPE CONNECTIONS WHILE ATTACHED TO THIS HEATER BECAUSE DAMAGE
TO THE HEATER WILL RESULT. DOING THIS WILL VOID THE WARRANTY.

Eemax strongly recommends that the heater be supplied directly from the main cold water line when
possible. This helps to avoid a potential water flow interruption to the heater which could lead to a
failure of the heating element.

For optimum performance, we recommend the use of isolation valves (full flow ball type) on the inlet
and outlet pipes.

3) Remove the cover. Connect the pre-assembled
inlet and outlet pipes to the heater and fully open
the inlet and outlet ball valves. Check for water
leaks. If a leak is at a compression fitting, slowly
tighten the compression nut until it stops. Replace
the cover.

4) Open the hot water faucet and run the water a
minute or two until the flow is continuous and free
of air pockets. Close the faucet and install the
aerator (if supplied). Failure to install aerator (if
supplied) will result in lower-than-expected heater
performance.
