Amtrol fpt-1 Please Read The Following Instructions Carefully, Location of the FIRE-X-TROL

PLEASE READ THE FOLLOWING INSTRUCTIONS CAREFULLY

IMPORTANT GENERAL SAFETY INFORMATION -

ADDITIONAL SPECIFIC SAFETY ALERTS APPEAR IN THE FOLLOWING INSTRUCTIONS.

EXPLOSION HAZARD. Failure to follow instruc- tions in the accompanying product manual can cause rupture or explosion, possibly causing serious or fatal injury, leak-

ing 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

QUALIFIED PROFESSIONAL.

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

2.Hydraulic system pressure must be at zero.

3.Attach nitrogen or dry air (-50°F/-46°C dew point or lower) supply to expansion chamber charging valve.

Pre-charge with nitrogen or dry air (-50°F/-46°C dew point or lower) only.

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 Istructions

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.
