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 licensed professional immediately. Current copies of the Product manual can be viewed at www.amtrol.com. Use proper safety equipment when installing.

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.

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.

READ CAREFULLY THE PRODUCT

INSTALLATION & OPERATION INSTRUCTIONS.

FAILURE TO FOLLOW THE INSTRUCTIONS AND WARNINGS IN

THE MANUAL MAY RESULT IN SERIOUS OR FATAL INJURY AND/

OR PROPERTY DAMAGE, AND WILL VOID THE PRODUCT

WARRANTY. THIS PRODUCT MUST BE INSTALLED BY A

LICENSED PROFESSIONAL. FOLLOW ALL APPLICABLE LOCAL

AND STATE CODES AND REGULATIONS, IN THE ABSENCE OF

SUCH CODES, FOLLOW THE CURRENT EDITIONS OF THE

NATIONAL PLUMBING CODE AND NATIONAL ELECTRIC CODE,

AS APPLICABLE.

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.

Excessive pressure can cause tank to explode.

Exercise care when filling a tank with air so the pressure does not exceed that required or does not exceed the working pressure of the tank as stamped on the nameplate. Failure to follow these instructions will result in serious personal injury or death and property damage.

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 is 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.

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

This product can expose you to chemicals including lead, which is known to the State of

California to cause cancer and birth defects or other reproductive harm.

IMPORTANT GENERAL SAFETY INFORMATION -

ADDITIONAL SPECIFIC SAFETY ALERTS APPEAR IN THE FOLLOWING INSTRUCTIONS.

EXPLOSION HAZARD. Failure to follow instructions in the accompanying product manual can cause rupture or explosion, possibly causing serious or fatal injury, leaking or flooding and/or property damage.

Location of the FIRE-X-TROL

®

1. The FIRE-X-TROL should be installed on the water supply line to the unhea ted area at a point between the backflow preventer and fill cup connection (Figure 1).

2. Once the FIRE-X-TROL is installed, check the system for any leakage.

Make repairs if necessary.

Installation

THIS PRODUCT MUST BE INSTALLED BY A

LICENSED PROFESSIONAL.

1. Visually inspect FIRE-X-TROL for any damage.

2. Hydraulic system pressure must be at zero.

3. Attach nitrogen or dry air supply to expansion chamber charging valve.

Isolate expansion chamber during system hydro test.

Operating Instructions

1. The FIRE-X-TROL is installed in the supply line between the backflow preventer and the fill cup connection. Its sealed-in air pre-charge chamber prevents water from entering it until the system pressure exceeds the pre-charge pressure. The FIRE-X-TROL is precharged to

25 psig (1.7 bar).

2. As the water/antifreeze solution temperature rises, expanded system fluid enters the FIRE-X-TROL’s non-corrosive reservoir. The precharge air chamber absorbs the pressure increase, keeping system pressure below maximum system rating.

3. As the water/antifreeze temperature decreases, pressure in the air chamber forces system fluid back into the system.

4. In antifreeze systems, this sequence allows the system antifreeze percentage to stay constant. Additional supply of water/antifreeze is not needed to replace fluid that would have escaped through a relief valve.

Do not use Oxygen - Explosion Hazard.

4. Pre-charge to 2 psig (0.14 bar) below system static pressure at tank location.

Never pre-charge below 25% of the system maximum rated pressure.

5. Remove charging hose. Carefully test charging valve for leakage.

6. Replace plastic cap.

Protect against freezing temperatures. Can cause damage and/or product failure.

Maintenance

1. Sprinkler system must be maintained and inspected per NFPA 25.
