READ CAREFULLY THE PRODUCT
INSTALLATION&OPERATIONINSTRUCTIONS.
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.
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.
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.
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 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 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.

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.

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
unheated 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.
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.
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 pre-
charge 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.
Maintenance
1. Sprinkler system must be maintained and inspected per NFPA 25.
