• Before connecting pieces to the water heater, it is

important to consider the alignment needed to connect

both the valve and the cold water tee to the hose.

• Isolate the water entering and exiting the water heater by

closing nearby shut off valves or by draining pipe lines.

INSTALLATION

Installation Instructions

IMPORTANT

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 (49°C) outlet temperature. The water heater is set at

140°F.

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 (60°C). Verify the outlet temperature of the TANK

BOOSTER and adjust in accordance with these instructions.

Non Return (Check) 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.

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.

Flush the system thoroughly before fitting Tank Booster:

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.

BOX CONTENTS

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 (3°C )from the commissioning

temperature, refer to the trouble shooting guide in Section 4.

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 by removing the unions.

IMPORTANT

HOT OUTLET

Apply sealing tape to the hot and cold

connections on the water heater. Thread the

bottom of the mixing valve onto the hot outlet

of the water heater, aligning as required, and

then tighten.

Thread the cold water tee to the cold inlet of the water

heater. Make sure that both the threads for the mixing valve

and the cold water tee are facing the same the back of the

water heater to allow easy installation of the hose.

COLD INLET

Place a strainer screen seal into one

end of the flexible hose. Connect this

end to the cold inlet on the mixing

valve. This is marked on the valve

with a “C.” (pictured right)

Place the washer into the opposite

side of the flexible hose. Connect this

end into the side of the cold water

tee as shown. (pictured right)

COLD INLET

HOT OUTLET

Connect the cold water supply line to the inlet of the cold

water tee. Connect the hot outlet line to the outlet of the

mixing valve.

TESTING THE TEMPERATURE 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. ADJUSTING THE MIXED OUTLET 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.
