Amtrol Fill-Trol FT-109 Installation instructions

USE ONLY IN RESIDENTIAL CLOSED HYDRONIC
SYSTEMS. Do not install on domestic water
systems, or in open heating systems. Corrosion and tank failure may
result. Use a Therm-X-Trol®or Therm-X-Span®for domestic water
systems. Use a Radiant EXTROL®for radiant heating systems where air
elimination equipment or barrier tubing is not used.
READ CAREFULLY THE PRODUCT INSTALLATION,
OPERATING AND MAINTENANCE MANUAL.
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.
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 leaking could cause
property damage to the area adjacent to the appliance or to lower floors
of the structure.
RUPTURE OR EXPLOSION HAZARD. Do not
expose product to freezing temperatures or
temperatures in excess of 240°F. Do not adjust the pre-charge or
re-charge this Product except during installation or regular inspection.
Replace the Product and do not adjust the pre-charge if 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
may lead to Product failure, serious or fatal personal injury, leakage, and/
or property damage.
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. At
least once every 3 years or if discharge is present, a licensed professional
should inspect the pressure relief valve and replace if corrosion is evident
or the valve does not function. FAILURE TO INSPECT THIS VALVE AS
DIRECTED COULD RESULT IN UNSAFE PRESSURE BUILD-UP
WHICH CAN RESULT IN PRODUCT FAILURE, SERIOUS INJURY OR
DEATH AND/OR SEVERE PROPERTY DAMAGE AND VOID THE
PRODUCT WARRANTY.
Chlorine & Aggressive Water: The water quality
can significantly influence the life of this 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.
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. For more

INSTALLATION & OPERATION INSTRUCTIONS
NOTE: Inspect for shipping damage. 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, shows signs of corrosion, or if indicator cap is discolored, 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.

For Use In Closed Hydronic Systems Only

FILL-TROL®is a combination of an EXTROL®expansion tank and a
specially designed automatic fill valve. Together, they manage water
expansion and provide make-up water to provide satisfactory heating
system.
Pre-Installation
1. Visually inspect for any damage. Ensure expansion tank is sized
properly for the application (Figure 1).
2. With tank empty of water, remove plastic cap from air stem (Figure 2).
3. Adjust air precharge to desired system fill pressure. Unit is shipped at
12 PSIG.
4. Replace cap and tighten snugly, ensuring the cap is flush against the
tank surface.
FAILURE TO PROPERLY SEAL VALVE CAP
WILL RESULT IN LOSS OF PRECHARGE
CAUSING PRODUCT TO FAIL.
Installation
1. Drain the boiler system or isolate the area where the Fill-Trol will
be installed.
2. Install the Fill-Trol on the supply side of the boiler, on the suction-side
of the heating circulator(s) (Figure 3).
Mount tank vertically only. Ensure the piping can
support the entire weight of the tank when full
of water.
Do not install on a dead-end pipe or wherever air
can collect; causing internal corrosion and
possible leakage.
3. Make connection to heating system with 1/2” tapping marked SYSTEM.
4. Connect cold water supply to 1/2” compression fitting connection
marked SUPPLY
5. Pressurize the system and check for leaks. Repair as necessary.
6. Restart the boiler system and check for relief valve discharge. If the
relief valve drips, the tank may be improperly charged or undersized.
Operation
Water enters the Fill-Trol valve, passes through the removable strainer
and pushes open a spring-loaded check valve. It then flows through
the automatic shut-off valve which is held in the open position by the
diaphragm pushing against a pressure plate. This raises the fill-gate
stem allowing water to flow into the heating system. It is the precharge
pressure in the tank that sets the fill pressure.
The Fill-Trol is shipped with a factory precharge of 12 PSIG which
automatically sets the minimum fill pressure to 12 PSIG. Other minimum
fill pressures my be used by increasing or decreasing the air charge in the
tank. Carefully follow the instructions for changing the air charge.
Maintenance
A licensed professional should check the complete system, including
the expansion tank, yearly and more frequently as the system ages.
Checking the precharge allows a small quantity of air to escape and can
result in an insufficient air charge. Always check the precharge while
the tank is isolated and empty of water, and be sure to maintain the
proper precharge whenever the tank is inspected. Monitor the tip of the
inspection cap for discoloration (Figure 4) in addition to regular product
inspection. Contact the installer or a licensed professional if indicator
cap is discolored; tank replacement required. Do not rely on cap as sole
indication of tank condition.
