must be off during
installation or ser-
vicing of the con-

serious burns, the boiler should be thoroughly cooled
before installing or servicing control. Only qualified
personnel may install or service the control in accor-
dance with local codes and ordinances. Read instruc-
tions completely before proceeding.

unions to allow easy removal for service or replacement. Remove and

clean the feed valve strainer after the first feed cycle to remove any conta-

minents introduced during installation.

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 above 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.
