Installation and Operation Guide
SETTING/ADJUSTING THE OPERATING TEMPERATURE
e trutankless VERO BR/BC unit comes preprogrammed for an initial temperature setting of 120°F (49°C). is set point of
residential version can be changed by pressing the Temp Increase or Temp Decrease buttons to control the temperature from
90°F to 140°F (32.2°C to 60°C) in the residential model, or from 90° F to 180° F (32.2° to 82.2° C) in the commercial model, in
single digit increments. Properly used, the trutankless VERO BR/BC water heater will deliver the desired temperature, even
when the water ow varies, or when more than one hot water tap is open. Should the demand for hot water (ow) exceed the
unit’s capability, there will be a corresponding decrease in the temperature of the water delivered.

You may use higher or lower temperatures to suit your needs. Remember that maintaining lower hot water temperatures
will save additional energy. e eciency of the heater is not aected by mixing in cold water at the point of use because
the trutankless will simply detect a lower ow through the heater and adjust the power accordingly. Most users nd a happy
medium by setting their unit at 120°F.

FREEZE GUARD PROTECTION MODE
e VERO BR/BC trutankless Residential & Commercial 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). is 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. e freeze protection circuit
protects the heater only and is not sucient 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 a leak with a ow
greater than .05 GPM. 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 VERO BR/BC unit. When power is disconnected within the heater it
will not heat water. is option is particularly useful in condominium or high-rise applications where damage from ooding
can be signicant. Normal condensation will not trigger an alert.

INSTALLATION
CAUTION: It is required that a licensed plumber and electrician install the unit and
that all pertinent regional building codes be followed. Please read each of the
following notices and caution messages below before continuing with the
installation of this unit as they pertain to safety considerations.
Before removing the old tank water heater and undertaking installation, unbox the unit. Remove all parts from the box and
ensure all parts are included.
In general, the trutankless unit can be installed in the same location where the old tank water heater was located. However, to
ensure safe, trouble-free performance and keep the warranty in eect, the following precautions must be observed:
1. e trutankless unit must be installed where minimum clearances can be met, and indoors or under cover where it is
protected from the elements and extreme weather. Do not install the unit where it will be exposed to direct sunlight, rain,
snow, hail, salt spray, blowing sand, etc.
2. e unit MUST be installed in an upright orientation with the water ttings positioned below and pointing downward.
CORRECT INCORRECT INCORRECT
WARNING: Do not install the unit where it would routinely be splashed with water.
Avoid the potential for exposure of the unit to dripping water or collection of
condensation. ELECTRIC SHOCK MAY RESULT.
3. 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.
4. Note that a Temperature, Pressure and Relief (TP&R) safety valve is not required according to National Plumbing Codes
as instantaneous water heaters are not considered pressure vessels. Bollente strongly suggests consulting local code to
determine if required.
SAFETY NOTE: Commercial units (BC 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.

5. is 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.
FAILURE TO COMPLY WITH THIS INSTRUCTION VOIDS ALL WARRANTIES.
NOTE: e 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.
6. e 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.
7. Electrical service to the VERO 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 the chassis electrical access point which is best suited for your installation.
8. Place the unit where it will not be struck by objects and away from other sources of heat.
9. 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.
10. e unit must be mounted to wall studs or other structural member, or with wall anchors appropriate for the type of wall
surface and sucient to securely hold 40 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 possibility of personal injury or death.
11. trutankless electric water heaters are designed for a very long service life, but actual life expectancy will be directly
aected 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 soener or polyphosphate in-line lter may prolong the life of your unit.
MOUNTING THE UNIT
e unit requires the following minimum physical clearances:
• Front: 24˝ (61 cm)
• Back: 0˝ (0 cm)
• Sides: 1˝ (2.5 cm)

Installation and Operation Guide
NOTE: Bollente recommends covering the unit with plastic or other impermeable sheeting until all water connections have
been installed and tested, to protect the internal parts from potential leaks. Leave the tubing manifold connections uncovered
for access.
Next, the unit must be connected to the local potable water supply.
e VERO BR/BC has two plumbing connections:
• ¾˝ MNPT male (blue) cold water supply inlet (rightmost when facing the unit)
• ¾˝ MNPT male (red) hot water outlet
Figure 5 — Plumbing Connections
C W I C (B A)
First, connect the inowing Cold Water Supply to the INLET connection, indicated by the Blue “Inlet Water” tag. is is
accomplished by connecting the recommended ¾˝ x 12˝ stainless steel braided ex hose from the potable cold water supply to
the unit’s ¾˝ NPT inlet. Using a wrench, attach the stainless ex lines to the inlet connection.
NOTE: Take care to NOT over-torque these connections (both cold and hot.) Doing so induces stress on the heating manifold
assembly. Manifolds damaged by over-tightening these connections are NOT covered by warranty.
NOTE: e VERO BR/BC unit is shipped with an in-line screen lter which should be inserted in the cold (inlet) connection.
e use of this lter is optional, but it is highly recommended, especially in new constructions where debris may be present
in the line. e gasket is placed over the domed side of the screen, then the domed side is inserted into the cold (inlet) pipe so
that the gasket is between the pipe and lter ring. Ensure that the assembly is well-seated with no gaps between the inlet pipe,
gasket, and lter ring before attaching the ex line to the connection.
H W O C (R A)
Next, connect the outowing Hot Water Supply main to the Outlet connection, indicated by the Red “Outlet Water” tag. is
is accomplished in a manner identical to connecting the inlet supply.
Turn on the water supply to the system. Open a hot water tap in the house to allow water to ow.
NOTE: Outowing water will be cold at this point of installation. Water will not ow hot until electrical supply is connected.
Verify that the inlet and outlet connections are leak-free, both with water owing and with the water ow stopped. Maintain
water pressure and check for leaks for a minimum of ten (10) minutes. If a slight leak is noted at either of the stainless steel
exible line connection points, carefully tighten further with both wrenches as noted above.

trutankless VERO BR/BC units have been designed to be maintenance-free*, yet periodic system checks are
recommended.
*In areas where the water hardness exceeds 180 PPM or 10.5 grains/gallons, a water soener or lter needs to be installed
and system checks, particularly of sedimentation accumulation in the ow sensor, should be carried out annually. Failure to
install a ltration or soening system in areas with very hard water voids this warranty completely.
WARNING: Always turn off the power circuit breakers at BOTH the main electrical
panel and at the unit access panel! High voltage is present in the system. Personal
injury or death can result if caution is not taken!
e following items should be checked at each inspection:
• Flow Sensor (paddle wheel clear of any sediment)
• Breakers (corrosion)
• Inlet pipe connection (is it tight and dry?)
• Outlet pipe connection (is it tight and dry?)
• Flush Pipe Connection (is it tight and dry?)
• Surrounding heater – Clean and free of dust and debris
In case of an error message from the trutankless VERO BR/BC Water Heater, turn o all the hot water faucets. Wait for one
minute. Turn a hot water faucet back on. If the error message persists, call your licensed contractor or authorized service
technician. Do not attempt to self-service the unit!

APPENDIX
COMPONENT TERMINOLOGY
Heating Chamber: Made of heat insulator-coated copper tubes connected in series (serpentine), this chamber
is where the water ows through and is heated by over 20 feet (6 meters) of internal
heating elements.
Wiring Harness: is harness provides for the electrical connectivity between the heating elements,
mechanical relays, solid state relays, transformer and the supplementary load center with
quad circuit breakers.
Safety Relays: Eight relays completely cut power to the heating elements in case of a leak, temperature
cutout and rmware fault.
TRIACS: TRIACs regulate, via rmware control, the amount of power to the elements in order to
smoothly heat the water to the desired temperature. Residential units contain four (4)
TRIACs; commercial units contains eight (8).
Over-Temperature Switch: Monitors the internal temperature of the heating chamber.
If the temperature of residential water heater exceeds 158°F (70°C), the Over-Temperature
switch will shut down the heater as a safety precaution. e heater will automatically reset
this switch when the temperature drops back below 122°F (50°C).
If the temperature of commercial water heater exceeds 197.6°F (92°C), the OverTemperature switch will shut down the heater as a safety precaution. e heater will
automatically reset this switch when the temperature drops back below 161.6°F (72°C).
Hot Water Outlet: ¾˝ NPT and port for temperature sensing thermistor; heated water comes out at
this location.
Flow Sensor: is sensor determines the incoming water ow rate and communicates that to the
microprocessor controller board.
Incoming Water Inlet: ¾˝ NPT and port for temperature sensing thermistor; where cold water enters the heater.
Wiring Block Access: Electrical wire access to main terminating lugs (2 hot, 1 ground.) Electrical wire is top fed.
Quad Circuit Breakers: Simplifying installation, the circuit breakers provide an internal shut-o to the water
heater. e size of the circuit breakers is dependent on the amperage model of the unit.
Display: Backlit LCD with push-button control.
Controller Board: e brain of the heater. It controls the advanced features including temperature set point, time
of use, startup delay and gallon/time limits.
