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.

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.

SAFETY PRECAUTIONS

• Scalding Risk: Water temperatures above 125°F (52° C) can cause severe burns, resulting in severe injury or death.
• Scalding risk can be reduced at 120°- 125°F (49° – 52° C), but even 120°F (49°C) water can cause scalding injuries (see chart below):
  Temperature| Time for a Mild First Degree Burn| Time for Permanent Second Degree Burn
  ---|---|---
  120°F (49°C)| 3 Minutes| 9 Minutes
  122°F (50°C)| 1 Minute| 5 Minutes
  126°F (52°C)| 30 Seconds| 90 Seconds
  131°F (55°C)| 5 Seconds| 25 Seconds
  140°F (60°C)| 2 Seconds| 5 Seconds
  149°F (65°C)| 1 Second| 2 Seconds
  154°F (68°C)| Instantaneous| 1 Second
• Your water heater thermostat (temperature control) temperatures should never be turned above 120°F (49°C) 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.
• Never take hot water temperature for granted
• Always hand-test hot water before using, especially when bathing infants and young children.
• Leaving a child unsupervised in the bathroom, even if only for a second, could cause serious injuries or death
• Never allow small children to use a hot water tap or draw their own bath water
• Your presence at all times is the best defense against accidents and scalding to children, the elderly, or the disabled.
• The 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.

INSTALLATION

Connect the mixing valve to the water heater
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.

Connect the cold water tee to the water heater
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 back of the water heater to allow easy installation of the hose.

Connect the corrugated hose to the water heater

• Connect the end of the flex hose with the strainer seal to the cold inlet on the mixing valve. This is marked on the valve with a “C”. (pictured right)

• Connect the opposite side of the flex hose with the face seal to the side of the cold water tee as shown. (pictured right)

Connect the Tank Booster to the water supply
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.

ALTERNATIVE INSTALLATION

The TANK BOOSTER can be installed sideways if there is no clearance above the water heater.

Warning: If 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 (49°C) 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.

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.

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 pipework 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

Date of Installation sticker

• Fill out and place the Date of Installation sticker on the water heater.
• 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.

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.

1. Remove the sticker on the adjusting knob and unscrew the knob securing screw with a Phillips screwdriver.

2. Lift the knob off the adjusting spindle then replace with the knob keyway (marked with a triangle on the knob) to the left of the temperature stop to raise the temperature, or to the right of the temperature stop to lower the temperature. The valve must be flowing water while adjusting outlet temperature. The valve can be adjusted between 90°F and 130°F.

3. Rotate the knob to select the desired temperature, clockwise to decrease the set temperature, or counterclockwise to increase the set temperature.

4. Lock the new set temperature by removing the knob and replacing it with the knob keyway located on the temperature stop on the valve body. Replace the knob securing screw.
