INSTALLATION GUIDE AND OWNER’S MANUAL
LavAdvantage™, AccuMix II™, & FlowCo™
ELECTRIC INSTANTANEOUS WATER HEATERS
Read and understand the instructions thoroughly before attempting the installation or service of the water heater. Failure to follow
the instructions can result in serious injury, death and/or property damage. The warranty of the water heater will depend upon
proper installation according to the instructions. Some heaters come supplied with separate faucet aerators. If supplied, the aerator
must be installed in the faucet for optimum performance. The heater must only be used to heat water and must be installed 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.
The installation must conform to the latest requirements of the National Electrical Code and all applicable state and local codes. This
information is available through local authorities. You must fully understand the requirements before beginning this installation.
This water heater is not required by UL 499 to employ a temperature and pressure relief valve (T&P). Check with local codes to find
out if one is required. If it is, the T&P valve must be installed in the outlet hot water pipe between the heater and the isolation valve.
BEFORE ATTEMPTING ANY INSTALLATION, MODIFICATION OR SERVICE OF THE HEATER, MAKE SURE THE
ELECTRICAL POWER IS DISCONNECTED.

GENERAL
Eemax® offers thermostatic, thermostatic with an integrated mixing valve, and non-thermostatic tankless electric water heaters.
To obtain optimum performance and energy savings, the water heater should be located as close as possible to the point-of-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.
LavAdvantage™, thermostatic heaters are designed to 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.
AccuMix II™, thermostatic heaters with an integrated mixing valve, are designed to take in cold water and heat it to temperatures
suitable for handwashing and other mild temperature uses up to a factory preset of 105°F. The heaters are also equipped with an
ASSE 1070-2004 approved mixing valve to meet UPC 407.3 and similar plumbing codes for public handwashing applications.
FlowCo™, non-thermostatic heaters, are designed to take in cold water and heat it to temperatures suitable for handwashing and
other fixed-flow applications.
MOUNTING THE UNIT TO THE WALL
The heater should be mounted on the wall under the sink, as close to the point-of-use as possible. Ideal position is fittings
pointed down; however, the heater may be mounted in any orientation.
Note: a logo decal has been provided to ensure branding is clearly displayed in any mounting orientation.
Make sure to leave a minimum of 8 inches service clearance at
the end OPPOSITE the fittings.
THIS HEATER MUST BE INSTALLED IN A LOCATION WHERE IT IS NOT SUBJECT TO FREEZING
TEMPERATURES.

PLUMBING HOOK-UP
The water heater is supplied with 3/8” brass 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 water heater which could lead to a failure of the heating element.
System Requirements:
Minimum turn on flow rates are family dependent:
oLavAdvantage: 0.2 GPM
oAccuMix II: 0.3 GPM
oFlowCo: vary by model (refer to the table below)
Minimum/maximum working pressure: 30 PSI/150 PSI
Optimal operating pressure range: 35 to 80 PSI

*Special suffixed models (i.e. CA, etc.), will have identical temperature rises as their base model
For optimum performance, Eemax recommends the use of isolation valves (full flow ball type) on the inlet and outlet pipes and a 40
mesh Y-Strainer on the inlet of the heater.
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!

Clean screen periodically for best performance.
BEFORE ATTEMPTING ANY INSTALLATION, MODIFICATION OR SERVICE OF THIS HEATER, MAKE SURE THE
ELECTRICAL POWER IS DISCONNECTED.
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 inlet water screen.
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.
Remove the cover. Connect the pre-assembled inlet and outlet pipes to the heater
(do not overtighten compression fittings) and fully open the inlet and outlet ball
valves. Check the system for water leaks at all plumbing connections. If a leak is
present at the compression fitting, slowly tighten compression nut until it stops –
do not overtighten.

GENERALIDADES
Eemax® ofrece termostatos, termostatos con una válvula mezcladora integrada y calentadores de agua eléctricos sin tanque no
termostáticos.
Para obtener un rendimiento óptimo y ahorro de energía, la unidad debe instalarse lo más cerca posible del lugar de uso. La unidad
viene con anillos y tuercas de compresión aptas para conexión directa a una cañería de cobre o PEX™ de 3/8". No utilice accesorios
roscados adicionales, lubricante para caños o cinta de teflón; ello anulará la garantía. NO SUELDE CAÑOS MIENTRAS LA UNIDAD
ESTÁ INSTALADA, esto ocasionará daños serios al calentador y anulará la garantía.
Los calentadores termostáticos LavAdvantage™ están diseñados para aceptar agua fría o precalentada y calentarla a temperaturas
adecuadas para uso doméstico normal hasta un punto de ajuste de temperatura máximo de 60°C. Los modelos con la opción "S" se
pueden usar como un potenciador de temperatura para elementos sanitarios hasta un punto de ajuste de temperatura máximo de
82°C. Las unidades con opción "ML" se configuran de fábrica a un punto de ajuste de temperatura máximo de 43°C y se
recomiendan para lavabos con lavamanos múltiples; consulte la sección 2 para obtener detalles del aireador suministrado. Las
unidades con opción "EE" se configuran de fábrica a un punto de ajuste de temperatura máximo de 32°C, lo que las hace adecuadas
para elementos de lavado de ojos de emergencia.
Los calentadores termostáticos AccuMix II™, con una válvula mezcladora integrada están diseñados para absorber agua fría y
calentarla a temperaturas adecuadas para el lavado de manos y otros usos de temperatura moderada hasta un valor
predeterminado de fábrica de 40,5°C. Los calentadores también están equipados con una válvula mezcladora aprobada ASSE 1070-
2004 para cumplir con el UPC 407.3 y códigos de plomería similares para elementos públicos de lavado de manos.

Para un rendimiento óptimo, Eemax recomienda que se usen válvulas de aislamiento (tipo esféricas de caudal total) en los caños de
entrada y salida y un filtro en Y de malla 40 en la entrada del calentador.
Limpie la pantalla periódicamente para obtener el mejor rendimiento.

ANTES DE INTENTAR CUALQUIER INSTALACIÓN, MODIFICACIÓN O FUNCIÓN DE ESTE CALENTADOR,
ASEGÚRESE DE QUE LA ELECTRICIDAD ESTÉ DESCONECTADA.
La ENTRADA y SALIDA de agua del calentador están etiquetadas. Instale válvulas
esféricas de caudal total en los caños de entrada y salida y haga correr agua por el
caño de entrada en el interior de un balde para eliminar residuos. Cierre la válvula
esférica de entrada.
*De lo contrario, puede obstruir la pantalla de entrada de agua.
Asegúrese de que el filtro de entrada esté instalado en el accesorio de entrada y
que los caños de entrada y salida estén correctamente alineados con las
conexiones del calentador para minimizar cualquier esfuerzo excesivo sobre el
calentador.
Retire la tapa. Conecte al calentador los caños de entrada y salida premontados
(no ajuste en exceso los accesorios de compresión) y abra por completo las
válvulas esféricas de entrada y salida. Compruebe que no haya fugas de agua en
todas las conexiones de plomería. En caso de existir una fuga en el accesorio de
compresión, ajuste lentamente la tuerca de compresión hasta que llegue al tope;
no ajuste en exceso.
