Mount the control box in any convenient location free from
excessive vibration where the temperature does not exceed 120ºF
(49ºC). Power supply and solenoids are 115/1/60 for Models
91/93, 131/133, and 251/253 ACA filter chambers; choice of 115
VAC, 230 VAC or 24 VDC on 51/53 models. Locate the power
supply terminal inside the control enclosure. Provide a hole as
needed for the power supply cord and connect to
L1 , L2 , and
ground. See the electrical schematic wiring diagram supplied in
your Customer Information Packet for more information.
Provide another hole in the control enclosure for wiring the
solenoid valves on the filter chamber. Locate the terminal strip
inside the control enclosure and connect the solenoid valve wiring
in the order shown in the electrical schematic wiring diagram
supplied in your Customer Information Packet. The order of wiring
determines the sequence of the filter bag cleaning air pulses.
3-14 Making ACA Series Filter Chamber Compressed
Air Connections
To provide proper filter bag cleaning, make sure that you regulate
the compressed air supply to 80 psig (551.6 kPa/ 5.52 bars). Air
consumption depends on frequency and length of cleaning air
pulses into the filter bags. Higher pressures can shorten the life of
filter bags; lower pressures cause poor filter bag cleaning.
Connect a ¼” (approx. 6.3 mm) air line to the bottom of the
solenoid valve air block. Make sure that the compressed air you
use is clean, dry, and free of oil. In-line filters can handle small
amounts of moisture; in-line desiccant filters or packed beds of
granular absorbing polymer can remove oil mist and condensed oil.
3-15 Installing VacTrac Vacuum Receivers and
Inventory/Vacuum Receivers
Vacuum uses one of three mounting systems: flange, suspension,
or silo mounting. Vacuum receivers and inventory vacuum
receivers use flange mountings only.
