MARK OF THE ORIGINATOR
Installation
1. Drain the boiler system or isolate the area where the RADIANT
EXTROL
®
will be installed.
2. Install the RADIANT EXTROL
®
on the supply side of the boiler, on the
suction-side of the zone circulator(s) (see Figure 1).
3. Once the RADIANT EXTROL
®
is installed, re-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 RADIANT EXTROL
®
is now operational and will absorb expanded
water during boiler operation.
Maintenance
1. A heating system professional should check the complete heating system,
including the RADIANT EXTROL
®
, yearly and more frequently as the
system ages.
Operation
1. The RADIANT EXTROL
®
is installed on the supply-side of the boiler
system. Its sealed-in air pre-charge prevents water from entering the
tank until the system pressure begins to rise.
2. As the water temperature rises, water enters the RADIANT
EXTROL
®
.
3. As the system cools, the diaphragm is forced downward. Water is
expelled from the RADIANT EXTROL
®
, back into the heating system.
NOTES:
Although the RADIANT EXTROL
®
does not have to be installed at the base of an
air purger, this installation is recommended to reduce air in the system and provide
a compact installation. Some method of air elimination is required to ensure an
oxygen-free system.
* Models RX-15 through RX-60 come with a 5 year warranty. All other
RADIANT EXTROL
®
models come with a 1 year warranty. See reverse side
for warranty information.
