EXPLOSION HAZARD. Failure to follow the

instructions in the accompanying product

manual can cause a rupture or explosion; possibly causing

serious or fatal injury, leaking or flooding and/or property

damage.

Use only with potable water system. Do not

operate in a setting with freezing temperatures

or where the temperature can exceed 240°F and do not exceed

the maximum working pressure specified for this Product in the

Manual. Mount vertically only.

This Product, like most Products under

pressure, may over time corrode. weaken

and burst or explode, causing serious or fatal injury, leaking or

flooding and/or property damage. To minimize risk, a licensed

professional must install and periodically inspect and service the

Product. A drip pan connected to an adequate drain must be

installed if leaking or flooding could cause property damage. Do

not locate in an area where leakage of the tank or connections

could cause property damage to the area adjacent to the

appliance or to lower floors of the structure.

Chlorine & Aggressive Water: The water

quality can significantly influence the life of

this Product. You should test for corrosive elements, acidity, total

solids and other relevant contaminants, including chlorine and

treat your water appropriately to insure satisfactory performance

and prevent premature failure

THIS IS THE SAFETY ALERT SYMBOL. IT IS USED TO

ALERT YOU TO POTENTIAL PERSONAL INJURY AND

OTHER HAZARDS. OBEY ALL SAFETY MESSAGES THAT

FOLLOW THIS SYMBOL TO REDUCE THE RISK

OF PERSONAL INJURY AS WELL AS PROPERTY

DAMAGE.

EXPLOSION OR RUPTURE HAZARD A

relief valve must be installed to prevent

pressure in excess of local code requirement or maximum

working pressure designated in the Product Manual, whichever is

less. Do not expose Product to freezing temperatures or

temperatures in excess of 240° F. Do not adjust the pre-charge

or re-pressure this Product except for any adjustments required

at the time of initial installation, especially if Product corroded,

damaged or with diminished integrity. Adjustments to pre-charge

must be done at ambient temperature only. Failure to properly

size the Product or follow these instructions may result in

excessive strain on the system and lead to Product failure,

serious or fatal personal injury, leakage and/or property damage.

Note: Inspect for shipping damage and notify freight carrier or

store where purchased immediately if damage is present. To

avoid risk of personal injury and property damage, if the product

appears to be malfunctioning or shows signs of corrosion, call a

Pre-Installation

1. Visually inspect THERM-X-TROL®for any damage. If

damage exists, return product for replacement.

2. Adjust pre-charge to equal incoming pressure.

If increasing the pre-charge

pressure above 55 psig, the

following steps must be followed:

a. Tank must be connected to the system with isolation

valve open.

b. System must be pressurized to 55-60 psi or slightly

higher than the pre-charge setting of the tank.

c. Isolation valve then needs to be closed.

d. The pre-charge pressure of the tank can now

be increased to the recommended high pressure

setting.

e. Bring system up to pressure, and then open the

isolation valve to the tank.

Failure to follow these instructions could result in

damage to the bladder or diaphragm and void all

warranties.

3. Replace and tighten plastic cap on air fitting.

Installation

1. Install the THERM-X-TROL®on the city supply line to the

water heater at a point between the water heater and

backflow preventer, check valve or pressure reducing

valve (see Figure 1).

2. Once the THERM-X-TROL®is installed, check the

city supply line line for any leakage. Make repairs if

necessary.

3. Before the initial firing of the water heater, open any hot

water fixture and draw water until all air is removed from

the system. Turn the water heater temperature control

to desired ending temperature level, (see water heater

instructions).

4. To relieve initial thermal expansion, slightly open a

hot water faucet. Continue until water heater aquastat

temperature is satisfied. Once heater is at its operating

range, no further bleeding of expanded water is required.

5. The system water heater and THERM-X-TROL®will

now be operational. The THERM-X-TROL®will control

temperature and pressure increases caused by thermal

expansion to a level well below the water heater relief

valve setting.

Maintenance

1. A professional plumber should check the complete

heating system, including the THERM-X-TROL®, yearly

and more frequently as the system ages.

Operation

1. The THERM-X-TROL®is installed in the supply line

between the backflow preventer and the water heater.

Its sealed-in air pre-charge prevents water from entering

it until the system pressure exceeds the pre-charge

pressure.

2. As the water temperature rises, expanded water enters

the THERM-X-TROL®’s non-corrosive bladder. The

pre-charged air chamber absorbs the pressure increase,

keeping system pressures below the relief valve setting.

3. As hot water is used, the pressure in the air chamber forces

water back into the system until the THERM-X-TROL®is

empty. At this point, the pressure in the air chamber once

again equals the supply pressure.

4. Water temperature is not to exceed 240°F or fall below

35°F.
