CAUTION: Breaker must remain off until installation is complete.
IMPORTANT: The Heatworks MODEL 1 must be oriented
horizontally.
The cold water inlet must be on the bottom of the
MODEL 1, and the outlet must be on the top. (Shown in
Heatworks MODEL 1 Diagram; page 3)
Do not use any other mounting method than the
brackets and zip ties provided.
STEPS
1) Position (2) mounting brackets approximately 6 inches
apart and level to support the weight of the MODEL 1,
which is approximately 15 pounds when full of water.
HEATWORKS RECOMMENDS: Dry wall anchors are
strongly recommended for installation, or drill directly
into studs. Do not attach to drywall without drywall
anchors.
2) Secure mounting brackets to a flat surface, such as a
wall, using mounting (4) bracket screws.
3) Place the MODEL 1 on the brackets. Check the position
and orientation to ensure the unit is level, with the inlet
on the bottom and the outlet on the top.
4) Thread (2) cable ties through the brackets, around the

CAUTION: Breaker must remain off until installation is complete.
4) Connect the cold water supply line to the MODEL 1
inlet marked “inlet” on the bottom of the unit.
HEATWORKS RECOMMENDS: Install a manual shut-off
valve (ball valve) on the inlet side of the Heatworks
MODEL 1 to provide a convenient shut-off point.
5) Turn on the main water supply.
6) Purge all air from the water lines and MODEL 1 by
opening a hot water demand source (hot faucet, shower,
etc.). Allow water to run though the water heater for at
least 2 to 3 minutes. Water from faucet will not be hot at
this point.

plumbing codes.
STEPS
1) Flush the existing water lines to eliminate all plumbing
or plastic paste or residue caused by any previous
brazing or soldering.
2) Turn off the main water supply.
3) Connect the hot water line to the MODEL 1 outlet
marked “outlet” located on the top of the unit.
HEATWORKS RECOMMENDS: Use flexible water heater

When installing multiple MODEL 1 units in the same
location with the purpose of having them support the
same hot water demand, please refer to the diagram to
the right.
In this installation configuration the cold water supply
line is split into two dedicated water lines, one line for
each MODEL 1 unit. The hot water lines then converge so
the outlet of each MODEL 1 unit supplies one hot water
line.
CAUTION: Serious damage to your Heatworks MODEL 1
can occur if all air is not purged from the water lines and
MODEL 1, any time air might be introduced into your
home water system.
7) Carefully inspect all connections and unions for leaks.
HEATWORKS RECOMMENDS: Since this product does
not use a storage tank, the use of a temperature
pressure relief valve (T&P) is not required for most
installations. However, a T&P valve may be required to
meet plumbing codes in your area.
CAUTION: The maximum recommended operating water
pressure for the Heatworks MODEL 1 is 100 PSI. Consult
your licensed plumber for specific information regarding
your water pressure.

SERIOUS BODILY INJURY OR DEATH COULD OCCUR IF
YOU IGNORE THIS WARNING.
The Heatworks MODEL 1 must be installed by a licensed
electrician in accordance with all applicable national,
state, provincial, and local electrical codes. Under no
circumstances should the Heatworks MODEL 1 be
installed without first shutting off all power to the unit at
the fuse or breaker box.
STEPS
1) Prior to wiring your Heatworks MODEL 1, a licensed
electrician should consult the Electrician’s White Paper on
page 16.
2) Verify all wiring (wire gauge) and circuit protection
(breakers) comply with national and local electrical codes.
3) The MODEL 1 requires two power conductors and one
grounding conductor.
a) The line conductors can both be phase, or one line
may be phase and the other neutral. (split-phase
installation)
b) Connect the two power and one ground wires to
the MODEL 1.
4) The MODEL 1 auto senses voltage from 110-250 VAC
(50/60 Hz). No adjustment is needed to set voltage.
5) Verify water supply to the Heatworks MODEL 1 is
turned on, and MODEL 1 has been purged of air.
CAUTION: Serious damage to your Heatworks MODEL 1
can occur if all air is not purged from the water lines and
MODEL 1 any time air might be introduced into your
home water system.

Amperes. To maximize the amount of temperature rise,
be sure to program your desired amperage to your
specific hot water needs. Also, be sure that your MODEL
1 has been installed and wired to meet the amperage
requirements programmed.
SETTING THE AMPERAGE

2) Select temperature between 50 °F (4 °C) and 120 °F
(49 °C).
3) Verify your desired temperature appears on the digital
display.
HEATWORKS RECOMMENDS: Because newer model
dish washers are typically equipped with an internal
heating element, and most laundry detergents are
intended for use in cold or warm water, there is no
longer a need to set your water heater to a temperature
above 120 °F.
STEPS
1) Press both buttons at the same time and release the
bottom button for °C.
2) Press both buttons at the same time and release the
top button for °F.
STEPS
1) Press the top button to increase the temperature
setting. Press the bottom button to decrease the
temperature setting.
