Amtrol Therm-x-trol st-20v-c Installation instructions

This product must be installed by a qualified

professional.

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 potable water. Do not operate in a setting

where the temperature can exceed 200° F or fall

below 35° F and do not exceed the maximum working pressure speci-

fied for this product.

RUPTURE OR EXPLOSION HAZARD. Like most

pressurized tanks, this tank can over time corrode,

weaken, and burst or explode.

Do not adjust the pressure or re-pressurize this

product except for any adjustments at the time of the

initial installation when the product is new.

Do not locate this product where leaking or flooding

could cause damage to the surrounding area.

Chlorine & Aggressive Water Warning. The water

quality can significantly influence the life of your

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.

a chemical known by the State of California to cause

cancer. This product contains a chemical known by the State of California

to cause birth defects or other reproductive harm.

Pre-Installation

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

return roduct for replacement.

2. Adjust pre-charge to equal incoming pressure.

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 Cold Water Supply (CWS) 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 CWS 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. T

o 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.

MARK OF THE ORIGINATOR

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.

* All ST-C Series models come with a 1 year warranty. See reverse side for warranty information.
