3.4.3 HEATER WIRING
in cold or damp environments, the heater serves to
prevent the electric solenoid valves from freezing
due to cold temperatures or condensation. if
optional solenoid valve heater is purchased, each
4 solenoid valve enclosures will contain a 70-watt
cartridge heater, 6, 8 and 10 solenoid valve
enclosures will contain a 120-watt cartridge heater
internally prewired to a thermostat.
the customer must provide a 100-130Vac,
50/60Hz, 1 amp power to the heater circuit for each
module. the power must be available to the module
solenoid valve enclosure(s) at all times (even when
the blower is shut down) to ensure temperature
regulation inside each solenoid valve enclosure
is continual. When multiple module solenoid
valve enclosures with heaters are installed, daisy
chain the wiring so that each heater will have
100/115Vac, 50/60 Hz at all times. Make certain
enough current is available to supply all heaters.
Example:
if three solenoid valve enclosures are supplied
with cartridge heaters, make certain the voltage
supply can deliver 3 amps (1amp per heater).
3.5 COMPRESSED AIR CONNECTION
Do not allow water and/or oil from the compressed
air system into the compressed air manifold
reservoir. to ensure a clean, dry air supply,
especially when the unit is installed outdoors, a
water filter with automatic drain and a coalescing
filter should be installed (refer to figure 10).
clean, dry, 90-110 PSiG (6.2-7.6 Bar) compressed air
is required for the pulse cleaning system to function
properly. compressed air consumption is noted on
the uaS sales drawing. a shut-off valve, pressure
regulator and pressure gauge should be installed close
to the Sfc unit. uaS recommends dedicated oil and
water removal filters be used to ensure clean, dry air is
delivered to the pulse system. contact your local Sfc
representative for information about uaS’ Pneumatic
Valve assembly. refer to figure 10 for recommended
compressed air piping and table 1 below for proper
compressed air line sizing.
NOTE:
using table 1, select the proper diameter
compressed air line pipe to supply your dust
collector. the final connection size is a female
1” nPt fitting on each module.
NOTE:
Purge the compressed air line to remove any
debris prior to making the final connection to
the Sfc compressed air manifold(s). apply
pipe fitting sealant on all compressed air supply
pipe fittings and connections.
3.6 ASSEMBLY OF OPTIONAL EQUIPMENT
3.6.1 BLOWER PACKAGE INSTALLATION
TIP OVER HAZARD
anchor dust collector to concrete pad prior to
installing blower assembly. Make certain all
hardware is properly tightened.
if a top-mount blower package was ordered, read
the manufacturer’s
Installation and Operation Manual
completely before installing the blower. the blower
Installation and Operation Manual
is attached to the
fan package. Perform all pre-installation checks prior
to installing the blower.
TIP OVER HAZARD
if blower package has a 20 HP (15 kW) motor or
larger, ensure the blower support legs are installed
beneath the clean air plenum of the module to
which the blower will be mounted.
for top-mount blower packages of 20 HP (15 kW) or
larger, an additional set of support legs is provided.
the additional support legs must be mounted under the
filter module supporting the blower package (refer to
figure 11). Bolt the mounting plate to the bottom of the
appropriate clean air plenum with the hardware provided.
Bolt the leg assemblies to the mounting plate with the
hardware provided. Secure leg assemblies to the concrete
mounting pad with appropriate anchoring hardware.
remove the clean air plenum cover plate on top of the
filter module and save the mounting hardware. ensure
ribbon gasket remains on the unit. Lift blower package
using safe, suitable means and position blower base holes
over filter module holes with blower discharge pointing in
the desired direction. Secure with bolt/washer assemblies
previously removed. top-mount blower packages include
a blower outlet damper. install blower damper to outlet of
blower assembly with hardware provided.
if the blower package is a ground-mount blower, read
the manufacturer’s
Installation and Operation Manual
completely before installing the blower. the blower
Installation and Operation Manual
is attached to the
fan package. Perform all pre-installation checks prior
to installing the blower.
outlet ducting from the Sfc unit to the blower
package can be connected to either the top or bottom
clean air section access panel(s). it is recommended
industry practice to provide vibration isolation between
the blower inlet and the dust collector outlet ducting.
