IMPORTANT!
Workingaroundelectricityrequiresproperskillsandknowledge–andshouldnotbe
performedbysomeonewhoisnotfamiliarortrainedinthistrade.Therefore,weHIGHLY
recommend that you solicit the services of a licensed and qualified
“Electrician/Plumber”familiarwithtanklesswaterheaterinstallation.
All electrical work and setting the unit to the wall should be completed before any
electricalwiringconnections.
IMPROPER INSTALLATION CAN CAUSE INJURY OR EVEN DEATH.
I) WALLFIXING
- Turn off the power or running water.
-Mark thepositionofthepointsofthe3screws.Notethatwerecommendleaving6
inchesclearance(free)aroundtheheater,therebyfacilitatingtheproperinstallation
and maintenance.
- The heater must beinstalled vertically and secured with 3 screws using the“drill
hole template” included with this heater.
-Set the heater at the pointswherethescrewsshouldgo,usetheadaptersand
screws provided.(viewphotos)
II) PLUMBING
- Uses tainless steel flexible hose or copper tubing from ½" to enter and leave
the water heater.(Right side water inlet, hot water outlet, left.) When you have
water pipes reduce the manother size to ½".
- Do not use PVC, CPVC or plastic supply lines to connect the unit. A pipe 16"of
copper or stainless steel must be connected to the input and output of the
heater.
- Connect the isolation valve at the entry inlet pipe of the heater and make sure
you install a rubber washer. Do not apply excessive force to tighten connectors.
Be sure to clean the pipes before connecting the heater to the main line, clean
all the impurities of the pipe allowing water to flow for a few minutes, check for
leaks.
Any residue or dirt in the pipes may cause internal damage to the unit. We
recommend installing a sediment filter before the entry of water to the heater.
Hard water or water with high levels of minerals and alkali can cause damage to
this unit. When this is the case, we recommend the use of a (non-salt) water
softening system.
III) ELECTRICITY
- Install a fuse box or switch (“breaker") for exclusive use of the heater. Based
on the power of the model obtained using the cable for your unit according to
the power and model purchased. Find a detailed guide to the power and cable
type used in the table below. Connect the ground, as indicated in the Electrical
Code.
Find a detailed guide to the power and cable type used in the table below.
Connect the ground, as indicated in the Electrical Code.
Once installed the heater, let the water flow through the unit before turning on
electricity.Whenallconnectionsaresatisfactorilypreparedinstalltheheatercover.
With the insulated container off and flow modifier (optional) fully open, the faucet
must be opened fully to get maximum water flow at the exit. This is necessary to
ensure that the water tank is full before turning your energy is an essential step to
protecttheresistance.

These heaters are of the closed type (closed system with no ventilation pressure)
suitable for fitting to the normal input of cold water with a maximum of 150 PSI (10
bar).Theymustbefittedwithapressurevalveadjacenttotheentrance.

When installed in a location that could freeze the heater must be isolated and
drained.

- The fuse does not give personal protection against electric shock. Improving
electrical safety: A single ground fault breaker (GFCI), 30-50 Amp (depending on
configuration and requirements) or a residual current device (RCD) must be
installedonthiscircuit.

- We recommend that you install the unit under the sink in main bathrooms or
utility areas. This will allow for lower amperage usage and a reduced heat loss
from longer pipe runs.
- For additional savings, reduce the water flow valve at the inlet of the heater so
the temperature increases.
WARNING! THIS APPLIANCE MUST BE PROPERLY GROUNDED!

5. The switch must be accessible and clearly identifiable, but out of reach of a
person with a fixed shower. Except for the cable that has a cable of a key switch,
and must be placed so that it is not possible to touch the switch body standing in a

IMPORTANT!
The size of the switch and wire gauge must meet all local, state, provincial and
national electrical codes in your area - these are just guidelines that apply to most
installations. Some codes require the use of electrical substations for the
installation panel, especially when heater is not mounted within line of sight of the
main electrical panel. Wiring must be sized to maintain a voltage drop of less than
3%underload.

- Open the hot water tap and the tankless hot water heater will activate, thus
producing hot water. Mix hot with cold water to achieve the desired output
temperature.

- In cooler regions or cooler seasons of the incoming water temperature will cause
a variation in the output temperature. The temperature settings allow for
