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 employ 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.

SAVE THESE INSTRUCTIONS

GENERAL

The Eemax, Inc.™ LavAdvantage 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.

LavAdvantage heaters accept cold or preheated water and heat it to temperatures suitable for normal domestic
usage up to a maximum temperature setpoint of 140°F. Models featuring the “S” option can be used as a
temperature booster for sanitation applications up to maximum temperature setpoint of 180°F. “ML” option
units are factory set to a maximum temperature setpoint of 110°F and are recommended for multi-lavatory
handwashing applications – refer to section 2 for supplied aerator details. The “EE” option units are factory set
to a maximum temperature setpoint of 90°F, making them suitable for emergency eyewash applications.

To obtain optimum performance and energy savings, the unit should be located as close as possible to the point­of-use. The unit is supplied with compression rings and nuts suitable for direct coupling to 3/8” copper or PEX™
piping. Do not use additional screwed fittings, pipe dope or teflon tape – doing so will void the warranty. DO
NOT SOLDER PIPES WHILE THE UNIT IS INSTALLED as serious damage to the heater will result and the warranty
will be voided.

1) MOUNTING THE UNIT TO THE WALL

THIS HEATER MUST BE INSTALLED IN A LOCATION WHERE IT IS NOT SUBJECT TO

FREEZING TEMPERATURES.

1. The heater should be mounted under the sink as close to the point-of-use as possible. Ideal position is

fittings pointed down, but the heater can be mounted in any orientation.

Note: an additional logo decal has been provided to ensure branding is clearly displayed in any mounting
orientation.

2. 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.
Replace the cover.

2) PLUMBING HOOK-UP

BEFORE ATTEMPTING ANY INSTALLATION, MODIFICATION OR SERVICE OF THIS HEATER,

MAKE SURE THE ELECTRICAL POWER IS DISCONNECTED.

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!

1. The heater’s water INLET and OUTLET are labeled. 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. FAILURE TO DO SO MAY

CLOG THE HEATER!

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.

The heater is supplied with brass 3/8” compression fittings that are compatible with either copper or plastic
pipes. Make sure these fittings are used for this installation. Contact your Eemax representative for further
information.

Eemax strongly recommends that the heater be supplied directly from the main cold water trunk 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.

System Requirements:

• Minimum/maximum working pressure: 30 PSI/150 PSI

• Optimal operating pressure range: 35 to 80 PSI

• Min flow rate 0.2 GPM

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