• UNIVERSAL COMPATIBILITY: The VXT feeder can be used with virtually
any probe or float-type low water cut-off.
• FEED COUNTER: Brightly illuminated feed cycle counter displays the
amount of water added to the boiler – essential in diagnosing water loss
problems that can severely shorten the life of a steam boiler. Built-in mem-
ory prevents power interruptions from clearing the counter.
• PROGRAMMABLE FEED DELAY SETTINGS: Helps prevent flooded boilers.
Allows time for condensate to return to the boiler before starting feed
cycle – ensuring that additional water is needed.
• PROGRAMMABLE FEED AMOUNT SETTINGS: Six settings provide two
ways to feed: 1-5 gallon settings feed bove the Low Water Cut-Off to
restore boiler's normal operating level. Or, select LWCO setting to end the
feed cycle when the Low Water Cut-Off re-energizes the burner.
• UNDERFEED PROTECTION: If one feed cycle is not sufficient to restore
boiler operation, the VXT will delay and feed one additional cycle.
• LOCKOUT FLOOD PROTECTION: The VXT locks-out to prevent steam sys-
tem flooding and costly water damage if burner operation does not
resume after two consecutive feed cycles.
INSTALLATION
Step 2
WARNING – To
prevent electrical
shock or equipment
damage, power
must be off during
installation or ser-
vicing of the con-
trol. To prevent
Feeder must be installed with a manual by-pass. Use isolation valves and
unions to allow easy removal for service or replacement. Arrows on VXT
valve indicates direction of water flow.
IMPORTANT: It is important to prevent any contaminants from entering
the feed valve during or any time after installation. The feeder should be
installed with non-ferrous plumbing materials only to prevent rust from
contaminating the valve. Apply pipe compound sparingly. Remove and
clean the feed valve strainer after the first feed cycle to remove any conta-
minants that could have been introduced during installation. See Service /
Maintenance on page 4 for additional information.
