Your water heater thermostat (temperature control)
temperatures should never be turned above 120°F without a
properly installed, properly commissioned and functioning
Thermostatic Valve
Do not leave children, the elderly, or the disabled
unattended in a bathtub or shower
oNever take hot water temperature for granted
oAlways hand-test hot water before using, especially when
bathing infants and young children
oLeaving a child unsupervised in the bathroom, even if
only for a second, could cause serious injuries or death
oNever allow small children to use a hot water tap or draw
their own bath water
oYour presence at all times is the best defense against
accidents and scalding to the elderly, infants and young
children.

oThe temperature at which injury occurs varies with the
person’s age and the time of exposure. The slower
response time of children, elderly, or disabled persons
increases hazards for them.

Warning: If at any time the TANK
BOOSTER thermostatic valve is removed,
decommissioned, or suspected of being
faulty, immediately revert the water
heater temperature setting to no higher
than 120°F in accordance with the water heater
manufacturer’s instructions.
The TANK BOOSTER is a temperature limiting valve. It must
be installed and commissioned in accordance with
manufacturer’s instructions.
Improper installation or maintenance can cause unsafe
outlet water temperatures that can cause immediate injury
or death

3. Installation Guidelines
Failure to comply with all aspects of these instructions may result in unsafe
performance.
All installations must comply with relevant State, Provincial and Local Authority
requirements.
Delivery Temperature:
Every valve is factory set for 120 F outlet temperature, with a 140 F hot water
inlet temperature.*
*NOTE: To ensure delivery of the desired mixed water temperature at the outlet the installer
must adjust and verify the temperature at the outlet by carefully following instructions on the
following page.
To Achieve Maximum Hot Water Delivery Performance
To achieve maximum hot water delivery performance, the TANK BOOSTER
must first be installed on the water heater in accordance with these instructions.
Once installed consult the water heater manufacturer’s instructions and increase
the temperature control device to around 140°F. This has the added benefit of
being a temperature determined by the OHSA as being sufficient to kill
Legionella bacteria. Verify the outlet temperature of the TANK BOOSTER and
adjust in accordance with these instructions.
Non Return Valves:
Non return valves are integrated in the cold and hot water inlets of the valve. For
correct and safe system function, ensure that the check valve is clean of debris
and functioning correctly.

Flush the system thoroughly before fitting Heatguard:
It is critical that all debris is flushed from the pipe-work prior to installing the
valve. Not flushing the system properly is the most common cause of system
difficulties.
Check:
Measure and note all site parameters (pressure, temperature, etc.) and
check against the specifications of the chosen valve. If the site conditions
are outside those specified for the valve then they must be rectified prior
to installing the valve.
Valve MUST NOT be subjected to heat during installation as this may
damage the valve internals.
Valve MUST NOT be fitted on steam-supplied systems, but to water
systems only.
Valve MUST NOT be frozen. If the valve is installed in a situation where
freezing is a possibility, then suitable insulation must be fitted to prevent
damage to the valve.
DO NOT use excess thread sealant (in liquid, tape or other form) as this
may cause the valve to fail.

CHECKING / SERVICING THE MIXING VALVE
Note that this thermostatic mixing valve is a SAFETY VALVE.
We recommend that the valve is checked at least once per
year to ensure its continued function. For installations with
poor or unknown water quality, or other adverse supply
conditions, it may be necessary to check the valve at more
frequent intervals.
The temperature should be checked at the same outlet as was
used for commissioning in the first instance. If the temperature is more than 5°F
from the commissioning temperature, refer to fault finding guide below.
There may be some variation in the temperature of the water from the
thermostatic mixing valve due to seasonal temperature variations in the cold
water supply.
The check valve can be easily accessed for cleaning via the flexible hose
connection.
If the water supply is of poor or unknown quality, a filter or strainer should
be fitted at the inlet to the system such that the cold inlet to both the water
heater and the mixing valve are protected from dirt and debris.

Installation Procedure
Before connecting the tee-piece and mixing valve to the water
heater, it is important to consider the alignment required to
enable connection of the tee-piece to the mixing valve with the
flexible hose, and the positioning of the mixing valve to allow
easy access for adjustment. The position of the recirculation
port also needs to be considered.
1. Apply sealing tape to the hot and cold connections on the
water heater. Connect the non-grooved end of the union
fitting to the hot outlet of the water heater. Place a strainer
seal (bulge side
towards heater) on
the union fitting then
screw the nut onto the
mixing valve in the
orientation shown.

2. Connect the tee-piece to the cold inlet of the water heater,
ensuring that its mixing valve connection is aligned to allow
connection to the
mixing valve via the
flexible hose.

3. Place a strainer seal in one end of the flex hose (bulge
side towards flex hose) and connect this end of the flex hose
to the mixing valve cold
inlet. Connect the other
end of the flex hose to
the tee-piece.

4. Connect system cold water inlet supply to the tee-piece
inlet and the system hot water outlet supply to the mixing
valve outlet, as
shown.

5. Using a thermometer, test the mixed water temperature at
the nearest outlet being supplied by the valve. This should
be opened to allow a
minimum flow rate of 1.5
gpm (6 L/min). Allow the
water to run for at least
one minute to ensure
the mixed water
temperature has settled.
Thermo-strip
The thermo-strip included in this kit may be used to indicate the outlet
temperature of the mixing valve to the household.
It shall not be used to set the outlet temperature of the mixing device; this
must be performed as stated in the temperature setting instructions.
To install the thermo-strip, remove the adhesive backing and apply the
thermo-strip to the mixing valve outlet pipe-work no less than 10" from the
outlet connection.
For the thermo-strip to operate correctly it must only be installed on
copper or galvanised tube.

Adjusting Outlet Mix Water Temp***
*****Prior to setting the valve it is necessary for the hot water
source to be switched on and delivering hot water at the
design temperature.
1. Holding the 3/16”Allen key (supplied), loosen the locking
nut with a 7/16”
wrench.

2.Using the wrench to support the locking nut and prevent it
from rotating, turn the Allen key to adjust the outlet
temperature –clockwise to reduce the temperature, counter
clockwise to increase the temperature –until the desired
temperature is reached. The valve must be flowing water
while adjusting outlet
temperature.
