INSTALLATION AND OPERATION GUIDE

INTRODUCTION

Welcome to the world of endless hot water! Your trutankless device
is truly a marvel of modern design and engineering and is now
ready to supply you with unlimited hot water on demand.

REGISTERING YOUR UNIT

Your unit must be registered, registration verified, and connected to the Bollente Monitoring service in order for you to
gain remote access via https://home.trutankless.com/login.

Your plumber may have already registered the device upon purchase and/or installation. If that is the case, you will likely
have already received an email from trutankless containing your user ID and temporary password that you will need to
verify your registration and create your account at home.trutankless.com.

If your device is not already registered, then you may register it yourself, now.

Go to https://home.trutankless.com/login.

1 2

At the login screen, beside the phrase “Don’t
have an account?” click on the “Create New
Account” link to access the Registration page.

Enter your contact information (your email
and phone number are required so that we
can notify you of any pertinent information –
don’t worry, we will only contact you with your
permission or if there is a problem, and we do
not share your information with anyone.)

1

In a short while you will receive an email with a

3

link to accept the Terms of Service and confirm
your registration. Follow the instructions in the
the registration confirmation email you received
when connecting your trutankless to the internet.

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.

As you set the temperature, the
outer ring lights up turning the dial.

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.

*Suggested Temperature Settings:

Kitchen: 110°- 130°F (43°- 54°C)
Shower: 98°- 114°F (36°- 45°C)
Bath: 102°- 110°F (39°- 43°C)

As the water heats up, the color
fills in the white lines based on the
power percentage.

*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.

Once trutankless reaches the set
point, the center lights up.

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.

INSTALLATION AND OPERATION GUIDE

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.

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;

Aix the mounting brackets to the wall, using the dimensions in figure 1 to help position the system. Brackets
must be mounted to wall studs or with wall anchors appropriate for the type of wall surface if there no
convenient wood stud behind the surface.

Figure 2. Mounting Brackets

Remove the cover from the unit and set it aside. The trutankless unit has four (4) slots on the back panel that fit
over corresponding hooks located on the the top edge of each wall bracket. One of the two brackets supplied
with the trutankless unit has two (2) truss head Philips machine screws lightly threaded into it. Remove these
two screws and carefully set aside.

INSTALLATION AND OPERATION GUIDE

CONNECTING THE WATER SUPPLY

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.

The unit must be connected to the local potable water supply.

The MODEL TR/TC has two plumbing connections:

• 3/4˝ MNPT male (blue) cold water supply inlet (lemost when facing the unit)

• 3/4˝ MNPT male (red) hot water outlet

Figure 4. Plumbing Connections

Cold Water Inlet Connection (Blue Arrow)

1

First, connect the inflowing Cold Water Supply to the INLET connection, indicated by the Blue “Inlet Water”
tag. This is accomplished by connecting the recommended ¾˝ x 12˝ stainless steel braided flex hose from the
potable cold water supply to the unit’s ¾˝ NPT inlet. Using a wrench, attach the stainless flex 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.

21

3

Hot Water Outlet Connection (Red Arrow)

Next, connect the outflowing Hot Water Supply main to the Outlet connection, indicated by the Red “Outlet
Water” tag. This 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 flow.

NOTE: Outflowing water will be cold at this point of installation. Water will not flow hot until electrical supply is
connected. Verify that the inlet and outlet connections are leak-free, both with water flowing and with the water
flow 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 flexible line connection points, carefully tighten further with both wrenches
as noted above.

Pressure Relief Valve

Note that a temperature pressure and relief safety valve is not required according to national plumbing codes
as instantaneous water heaters are not considered pressure vessels. The trutankless comes equipped with a
mechanical thermal cut out and the copper manifold is not defined as a pressure vessel according to ASME. If
your water lines are plastic piping or tubing (PVC,PEX, Etc.), a pressure relief valve rated to equal or less than the
PSI rating of the tubing should be installed.

T&P valve may be required to meet installation codes in your area. If one is required, install the pressure relief
valve branched o the hot outlet side.

Switch ON the trutankless unit circuit breakers. The controller powers up and the LCD screen displays the
Startup screen for approximately 4 seconds.

Open a hot water tap inside the building and allow it to flow for a minimum of two (2) minutes to purge air from
HEX and protect unit from dry fire.

NOTE: The trutankless unit must sense active water flow before it will allow the elements to heat. The LCD
screen will be in lockout mode for a period of 120 seconds (2 minutes) while the water fills the heating tubes
completely and the startup sequence completes.

This completes the installation procedure. The trutankless Water Heater is now in service. Operation is as
simple as opening a hot water tap. The unit will then begin heating water and can typically reach the set-point
temperature in as little as 15-30 seconds.

NOTE: Remember that water already in the supply line may be cold, so it may take somewhat longer for the
hot water to reach the faucet. Upon closing the hot water tap, the unit automatically returns to standby mode.
That’s all there is to operating your trutankless Water Heater!

MAINTENANCE

trutankless units have been designed maintenance free*, yet periodic system checks are recommended.

*In areas where the water hardness exceeds 180 PPM or 10.5 grains/gallons, a water soener or filter needs to be installed
and system checks, particularly of sedimentation accumulation in the flow sensor, should be carried out annually. Failure
to install a filtration or soening system in areas with very hard water voids this warranty completely.

SYSTEM CHECKUP

WARNING: Always turn o 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!

The 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 MODEL TR Residential 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!

If you have multiple Trutankless Products interfacing with one another, the products will share certain information with each other, such as data on
when you use hot water in a particular outlet. This sharing may occur locally among devices, between Trutankless Products and your mobile device or
application, or on Trutankless’s servers. Understanding when you turn on your hot water and where, can help the products do things like ready the hot
water at the source before you need it.

Additional information about the limited circumstances in which information from your Trutankless account may be shared with third parties is
described below in the section titled “In what circumstances does Trutankless share my information?”.

Any Trutankless data that you choose to share with a third party is governed by that third party’s privacy policy while in that party’s possession.
Any data that Trutankless receives from third-party products and services will be processed and stored by Trutankless and will be treated in accordance
with this Privacy Statement. This information may be processed in the same ways as any other data that is a part of your Trutankless account or the
Trutankless logs.

INSTALLATION AND OPERATION GUIDE

WHAT ADDITIONAL INFORMATION DOES TRUTANKLESS COLLECT AND STORE WHEN A USER CONNECTS A TRUTANKLESS PRODUCT
TO THE INTERNET OR CREATES AN ACCOUNT?

To connect your Trutankless Product to our Services, or to access your Trutankless Product over the Internet from a computer, a smartphone or a tablet,
you will need to connect it to your Wi-Fi network. During setup, the Trutankless Product will ask for your Wi-Fi network name (SSID) and password
to connect to the Internet. It will save this information on the device, along with your IP address, so that you can access it and control it from your
computer, smartphone or tablet, and so that it can communicate with Trutankless servers and download soware updates.
Once connected to your Wi-Fi network, your Trutankless Product regularly sends the data described in this Privacy Statement (excluding your Wi-Fi
password) to Trutankless to provide you with the Services.

Additionally, when you create a Trutankless account, we collect and store your email address. From that point forward, your email address is used for
communications from Trutankless.

In addition, Bluetooth or other wireless communications-enabled Trutankless Products may broadcast an identifying signal wirelessly. This is used to
connect with your Bluetooth or other wireless communications-enabled devices (such as a smartphone or tablet) in order to deliver features.
Remember that when you visit our Sites, we collect personal information as described in our separate Privacy Policy for Trutankless Websites. Like most
Internet sites, we routinely record log entries (including information such as your IP address) and technical information (such as your browser type and
version) when your browser, mobile device or Trutankless Product contacts our servers.

HOW DOES TRUTANKLESS USE THE INFORMATION IT COLLECTS?

We use this information to provide, develop and improve Trutankless Products and services, including information to make assessments and
recommendations about products or safety. We may use your contact details to send you this information, or to ask you to participate in surveys
about your Trutankless use. We may also use this information in an aggregated, non-identified form for research purposes and to help us make sales,
marketing, and business decisions. We may use service providers to perform some of these functions. Those service providers are restricted from
sharing your information for any other purpose.
We use industry-standard methods to keep this information safe and secure while it is transmitted over your home network and through the Internet
to our servers. Depending on your location and type of data, Trutankless may process your personal information on servers that are not in your home
country.

IN WHAT CIRCUMSTANCES DOES TRUTANKLESS SHARE MY INFORMATION?

Under no circumstance do we share personal information for any commercial or marketing purpose unrelated to the delivery of Trutankless Products
and services without asking you first. We do not rent or sell our customer lists.

The following are the limited situations where we may share personal information:

• With your explicit consent: We may share personal information when we have your consent. One example of this would be if you sign up for programs
oered by our partners (e.g., energy or insurance companies). If you do this, we may share certain information with the partner. This could include
things like your enrollment information and the activation status of your device. Similarly, when you connect third-party devices and services to your
Trutankless Products, you are shown information about any proposed exchange of data. Your explicit consent is required to allow these exchanges on
your behalf and you can change your mind at any time.

• For external processing: We have vendors, service providers, and technicians who help with some of our processing and storage, including helping to
answer your questions. They may also assist with monitoring our servers for technical problems. These technicians (as well as Trutankless employees)
can access certain information about you or your account in line with this work but these technicians are not allowed to use this data for non­Trutankless purposes.

• As part of business transitions: Upon the sale or transfer of the company and/or all or part of its assets, your personal information may be among the
items sold or transferred. We will request a purchaser to treat our data under the privacy statement in place at the time of its collection.

• For legal reasons: We may provide information to a third party if we believe in good faith that we are required to do so for legal reasons. For example, to
respond to legal process, or comply with state and federal laws (or the applicable laws of foreign countries other than the United States).

We may share non-personal information (for example, aggregated or anonymized customer data) publicly and with our partners. This information may
also be shared with other users to help them raise awareness about safety issues or help us generally improve our system. We may also share non­personal information with our partners, for example, if they are interested in providing demand-response services or other incentive programs. We take
steps to keep this non-personal information from being associated with you and we require our partners to do the same.

Your personal information may be collected, processed and stored by Trutankless or its service providers in the United States and other countries where
our servers reside. As a result, your personal information may be subject to legal requirements, including lawful requirements to disclose personal
information to government authorities, in those jurisdictions.

29

If you select an outside party for the purchase, installation, or service of your Trutankless device and share your personal information, we cannot control
the collection, storage or sharing of information collected by that party. For example, the party that installed the device may retain information that
you provided to them to assist them in servicing the device if needed. Always check the privacy policies for any company that collects your personal
information.

HOW LONG DOES TRUTANKLESS SAVE MY PERSONAL INFORMATION AND HOW CAN I DELETE IT?

Trutankless generally stores your personal information on Trutankless’s servers until you delete or edit it, or for as long as you remain a Trutankless
customer in order to provide you with Trutankless Products.

As described above, some information is processed and stored directly on the Trutankless device. All personal information is encrypted as it is
transmitted to Trutankless and cannot easily be accessed.

You can delete the information on the Trutankless device by resetting it to the defaults (using Reset in the Settings menu).
You can access, amend or delete your personal information from Trutankless’s servers through the controls in your account. Because of the way we
maintain certain Services, aer your information is deleted, backup copies may linger for some time before they are deleted, and we may retain certain
data for a longer period of time if we are required to do so for legal reasons.

We comply with the US-EU Safe Harbor Framework and the US-Swiss Safe Harbor Framework as set forth by the US Department of Commerce regarding
the collection, use and retention of personal information from European Union member countries and Switzerland. Trutankless has certified (through its
parent) that it adheres to the relevant Safe Harbor Privacy Principles.

Please note that this Privacy Statement may change from time to time. We will provide notice of any changes on the website or by contacting you.

If you have any questions, please contact us at[email protected].

10. DISPUTES AND ARBITRATION

(a) Contact trutankless First. If a dispute arises between you and trutankless, our goal is to learn about and address your concerns. You agree that you
will notify trutankless about any dispute you have with trutankless regarding these Terms by contacting trutankless.

(b) Binding Arbitration. You and trutankless agree, subject to clause 11(c) (Protection of Confidentiality and Intellectual Property Rights), to submit
any claim, dispute, action, cause of action, issue, or request for relief arising out of or relating to these Terms or your use of the Services to binding
arbitration rather than by filing any lawsuit in any forum other than set forth in this section. Further you agree arbitration is final and binding and
subject to only very limited review by a court. You also waive your right to any form of appeal, review or recourse to any court or other judicial
authority, insofar as such waiver may be validly made. This provision is intended to be interpreted broadly to encompass all disputes or claims arising
out of or relating to your use of the Service. Subject to clause 11(c) (Protection of Confidentiality and Intellectual Property Rights), any dispute or claim
made by you against us or us against you arising out of or relating to these Terms or your use of the Services (whether based in contract, tort, statute,
fraud, misrepresentation or any other legal theory) will be resolved by binding arbitration except that you may take claims to small claims court if they
qualify for hearing by such a court.

(c) Arbitration Procedures. You must first present any claim or dispute to us by contacting trutankless to allow us an opportunity to resolve the dispute.
You may request arbitration if your claim or dispute cannot be resolved within 60 days aer presenting the claim or dispute to trutankless. trutankless
may request arbitration against you at any time aer it has notified you of a claim or dispute in accordance with clause 11(f) (Notifications). The
arbitration of any dispute or claim shall be conducted in accordance with the then current and applicable rules of the American Arbitration Association
as modified by this agreement. The place of any arbitration will be Phoenix, Arizona, USA, and will be conducted in the English language. Claims
will be heard by a single arbitrator. The arbitrator may not award relief in excess of or contrary to what this agreement provides, order consolidation
or arbitration on a class wide or representative basis, award punitive or consequential damages or any other damages aside from the prevailing party’s
actual damages, or order injunctive or declaratory relief, except that the arbitrator may award on an individual basis damages required by statute and
may order injunctive or declaratory relief pursuant to an applicable consumer protection statute. Any arbitration shall be confidential, and neither you,
nor trutankless nor the arbitrator may disclose the existence, content or results of any arbitration, except as may be required by law or for purposes
of enforcement or appeal of the arbitration award. Judgment on any arbitration award may be entered in any court having proper jurisdiction. If any
portion of this arbitration clause is determined by a court to be inapplicable or invalid, then the remainder shall still be given full force and eect.

(d) No Class Actions. There shall be no right or authority for any claims subject to this arbitration clause to be arbitrated on a class action or
consolidated basis or on bases involving claims brought in a purported representative capacity on behalf of the general public (including, but not
limited to, as a private attorney general).

(e) Fees and Expenses. All administrative fees and expenses of arbitration will be divided equally between you and trutankless. Each party will bear the
expense of its own counsel, experts, witnesses and preparation and presentation of evidence at the arbitration hearing.

(f) YOU MUST CONTACT TRUTANKLESS WITHIN ONE (1) YEAR OF THE DATE OF THE OCCURRENCE OF THE EVENT OR FACTS GIVING RISE TO A DISPUTE, OR
YOU WAIVE THE RIGHT TO PURSUE ANY CLAIM BASED UPON SUCH EVENT, FACTS, OR DISPUTE.
