Pre-Installation
1 Visually inspect for any damage. Ensure expansion tank is sized
properly for application (Figure 1).
2. Remove plastic cap from air valve.
3. With tank empty of water, adjust air precharge to match system fill
pressure.
4. Replace and tighten plastic cap on air valve.
FAILURE TO PROPERLY SEAL VALVE CAP
WILL RESULT IN LOSS OF PRECHARGE
CAUSING PRODUCT TO FAIL.
Mount tank vertically in downward position only.
Ensure the piping can support the entire weight
of the tank when full of water.
Models SX-30V through SX-160V are floor
standing and may not be hung from the piping.
Do not install the EXTROL on a dead-end pipe
or wherever air can collect. This can cause
corrosion and possible leakage.
Installation
1. Drain the boiler system or isolate the area where the EXTROL will
be installed.
2. Install the EXTROL on the supply side of the boiler, on the suction-side
of the heating circulator(s) (Figure 2).
3. Pressurize the system and check for leaks. Repair as necessary.
4. Restart the boiler system and check for relief valve discharge. If the
relief valve drips, the tank may be improperly charged or undersized.
5. The EXTROL is now operational and will absorb expanded water
during boiler operation.
Maintenance
A professional plumber 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.
