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 200°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.

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 200° 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

INSTALLATION, OPERATION & SERVICE INSTRUCTIONS

THERM-X-TROL®

THERMAL EXPANSION ABSOBERS (ST-5-C THROUGH ST-210V-C)

Part #: 9017-091 (04/11)

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.

For commercial water heater installations, contact

AMTROL for information.

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 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 water

reservoir. 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 treatment is not to exceed 200° F or fall below

35° F.

NOTE: Models are listed (ST-5-C thru ST-210V-C)

under ANSI/NSF Std 61 and City of Los Angeles.
