Resetting your unit without turning off the breakers can result in personal injury and damage
toyourwaterheater.
WARNING!Thereiswatercontainedinthecoilsofyourwaterheateratalltimes.Ifyourwater
heater is exposed to freezing temperatures, the water in the coils could freeze, causing a
breakin theheatexchangeroftheunit,orthesupplyandreturnlines.Thiskindofdamagewill
result in water running freely into the space where the water heater is located, which can
causeflooding. DONOTinstallthis water heaterwhereitmaybesubjectedtoa freeze.Ifyour

Thewiregaugenecessarywillvarybasedonamperageanddistancetothebreaker,
but 8 gauge wire is generally sufficient for most installations. If the distance is very
short,sometimessmallergaugewiremaybeused.Ifyouaren'tsurewhichgaugeof
wire should be used, contact an electrician. The supply wire, main switch and
circuit protection (Leakage Circuit Breaker) must be sufficient for the
amperage required. Please check the table above and the flow rate/temperature
rise chart for the appropriate amperage for your situation. Note that the lower the
amperage,thelowerthewatertemperaturerisewillbe.

This appliance MUST be grounded. Connect the ground wire, as indicated in the
ElectricalCode.
When all connections are satisfactorily prepared, install the heater cover. With the
insulated container off and water flow modifier (optional) fully open, the faucet must
be opened fully to get maximum water flow . It is necessary to ensure that the water
tank is full before turning the power on. This is an essential step to protect the
heatingelement.
Note that the above instructions are simply guidelines that apply to most
installations.

DO NOT USE PVC, CPVC or plastic supply lines directly to the unit.A16” copper or
stainlesssteelpipe must be connected to theheater and then adapted toa different
materialsuchas(CPVC,PVCorPEXPLASTIC).
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.

The water temperature is altered by increasing or decreasing the flow rate of the
water through the water heater, via the temperature control knob. Increased
amperagesettingswillresultinincreasedwatertemperature.
NOTE: If water pressure is low, the inlet pipe of the water should be ¾ "with outputs
of5/8".
The heater should be installed as close as possible to the point of use to avoid heat
loss.Iflongerdistancesarerequired,hotwaterpipesshouldbeinsulated.
Adjust heater temperature settings (located on the front panel of the heater) to the
desired output temperature. Lowering the power setting will save energy, but hot
watertemperaturewilldecrease.

We recommend that you install the unit under the sink in the main bathrooms or
utility areas. This will allow for lower amperage usage and a reduced heat loss from
longpiperuns.
For additional savings, reduce the water flow valve at the inlet of the heater so the
temperatureincreases.
