INSTALLATION AND OPERATION GUIDE
As you set the temperature, the
outer ring lights up turning the dial.
As the water heats up, the color
fills in the white lines based on the
power percentage.
Once trutankless reaches the set
point, the center lights up.
SETTING/ADJUSTING THE OPERATING TEMPERATURE
The trutankless unit comes preprogrammed for an initial temperature setting of 120°F (49°C). This set point can be
changed via the Temperature Controller on the Home screen from 90°F to 140°F (32°C to 60°C), in single digit increments.
Properly used, the trutankless Water Heater will deliver the desired temperature, even when the water flow varies, or
when more than one hot water tap is open.
In multiple unit configurations, each controller can be individually programmed, but the heater can only deliver one water
temperature at a time. Should the demand for hot water (flow) exceed the unit’s capability, there will be a corresponding
decrease in the temperature of the water delivered.
The Controller utilizes a touchscreen rotary adjustment.
Touch the indicator arrow and drag clockwise (right) to INCREASE the temperature;
drag counterclockwise (le) to DECREASE the temperature.
122° 122°122°
122° 122°122°
122° 122°122°
*These temperatures are only suggestions. You may use higher or lower temperatures to suit
your needs. Remember that maintaining lower hot water temperatures will save additional
energy. The eiciency of the heater is not aected by mixing in cold water at the point of use
because the trutankless will simply detect a lower flow through the heater and adjust the
power accordingly. Most users find a happy medium by setting their unit at 120°F.
*Suggested Temperature Settings:
Kitchen: 110°- 130°F (43°- 54°C)
Shower: 98°- 114°F (36°- 45°C)
Bath: 102°- 110°F (39°- 43°C)
0˚- 110˚F 110˚- 130˚F > 130˚F
The color of the dial is coded to change to visually indicate the temperature of the water.

INSTALLATION AND OPERATION GUIDE
FREEZE GUARD PROTECTION MODE
The MODEL TR/TC trutankless Residential Water Heater is designed such that, should the water temperature at either the
inlet or outlet cool to 41°F (5°C), the heater automatically warms the water to approximately 45°F (7°C). This cycle will
continue for as long as the unit experiences temperatures near the freezing point.
If the main power to the heater is o, the freeze guard protection feature will not operate. The freeze protection circuit
protects the heater only and is not suicient protection for water connections to and from the heater, including the Flow
Sensor and other optional devices. Any damage to the heater caused by freezing is not covered by warranty as it is the
responsibility of the user to ensure the heater is installed in an environment protected from freezing.
LEAK SENSOR
A leak sensor is built into the controller circuitry on the interconnect module and activates if it senses moisture. When
this happens, the controller starts an audible alarm, displays an on-screen message, sends an alert, if desired, and
disconnects the power within the MODEL TR/TC unit. When power is disconnected within the heater it will not heat water.
This option is particularly useful in condominium or high-rise applications where damage from flooding
can be significant.

Hot water outlet pipes leaving unit can be hot to the touch. Insulation must be used for hot water pipes located
36˝ (92 cm) or less from ground level due to burn risk to children.
SAFETY NOTE: Commercial units (TC Series) are designed forcommercial settings only, and can be set as high
as 180°F (82° C) for industrial processes including sterilization of equipment andutensils. EXTREME CAREshould
be taken when setting temperatures higher than140°F ( 60°C), such temperatures should not be directly used in
the shower or intended for contact with skin, there is risk of injury.
Bollente strongly suggests installing an appropriate Temperature, Pressure and Relief (TP&R) safety valve per
local code. Consult your plumber or professional service provider.
This unit should not be installed in a location where it may be exposed to freezing temperatures
(less than 32°F (0°C).)
CAUTION: This unit comes equipped with freeze protection. However, in the event that electrical power is lost
or is disconnected from the unit, there is NO freeze protection. FREEZE PROTECTION OF THE WATER HEATER
IS ONLY POSSIBLE WHEN ELECTRICITY AND NORMAL WATER HEATER FUNCTIONS ARE ENABLED. If you expect
freezing conditions while electrical supply is interrupted, WATER MUST BE COMPLETELY DRAINED FROM
WATER HEATER.
The installation of auto drain down solenoid valves is optional. However, Bollente strongly recommends that
these valves be installed so that water may be drained from the unit to prevent damage from freezing in case the
normal freeze protection should become disabled. If the valves are not installed, then any product damage due
to freezing will not be covered by the warranty.
FAILURE TO COMPLY WITH THIS INSTRUCTION VOIDS ALL WARRANTIES.
The unit should be located in an area where water leakage from the unit or connections will not result in
damage to the area adjacent to the unit. If such a location cannot be avoided it is recommended that a drain
pan be installed under the unit.

Electrical service to the model BR/BC trutankless water heater must be in accordance with all applicable
national electric safety codes, state/provincial and local electric and building codes.
NOTE: Bollente recommends you place the unit near the electrical service panel. A licensed contractor can help
you choose the unit location and which chassis electrical access point is best suited for your installation.
Place the unit where it will not be struck by objects and away from other sources of heat.
Install the unit where it can be mounted at eye level to allow easy access to the touch screen display for reading
and programming controls.
The unit must be mounted to wall studs or other structural member, or with wall anchors appropriate for the
type of wall surface and suicient to securely hold forty pounds if there is no convenient structural member
available.
WARNING: Failure to comply with this requirement may result in the unit falling from the wall, creating the
possiblity of personal injury or death.
trutankless electric water heaters are designed for a very long service life, but actual life expectancy will be
directly aected by water quality and use. If you do not already know the quality of your water, we advise
testing (your water department may be able to assist). Especially in areas where the water hardness exceeds
180 PPM or 10.5 grains/gallons, installing a non-salt based soener or polyphosphate in-line filter may
prolong the life of your unit.
The commercial version of the water heater is generally used in hotel, swimming pool and other places of large;
The commercial version of the water heater for shower use, set the temperature too high, there is a risk of burns;
