Instructions / Assembly

Model VXTC
•
Programmable Feed Delay Settings (0 to 10 Min)
• Prevents over-filling by allowing time for condensate to return to boiler before
initiating feed cycle. A “NO DELAY” delay setting is available for process steam
applications.
•
Programmable Feed Amount Settings (LWCO to LWCO+120 Sec)
• Includes one setting to raise the water level to the boiler control and five addi-
tional settings to raise the water level above the boiler control.
•
LED Status Indicator
• Displays current mode of operation. Also provides timer for convenient set-up of
programmable feed amount setting.
•
Manual Feed Button
• Allows for manual feeds with the touch of a button.
•
Lock-Out Flood Protection
• Locks out after sustained 10 minute feed cycle to prevent flooding.
•
Water Meter
• Heavy duty meter tracks make-up water added to system.
•
Fittings
• Includes fittings for easy attachment to 3/4" water line.
MODEL VOLTAGE DESCRIPTION/OPERATION
VXTC 120 VAC Designed to operate with all major low water cut-offs and pump controllers.
Upon a low water signal from the boiler control, the VXTC delays (from 0 to 10
minutes) to allow condensate to return to the system. If make-up water is
required following the delay period, the VXTC initiates a feed cycle. The VXTC
can be set to feed to the level of the boiler control or to varying levels above. The
heavy-duty water meter tracks all water fed into the system. The VXTC includes
water feeder, strainer, flow restrictor and water meter with 3/4" NPT fittings.
VXTC-WF 120 VAC Water Feeder as above without water meter. Includes water feeder, strainer and
flow restrictor.
WM-1 n/a Water Meter as described above without water feeder. Includes water meter and
3/4" NPT fittings.
