2.7.1 Air Manifold Assembly
(See Figure 37 Air Manifold Assembly)
To access the air manifold assembly, remove the
screws on the back (see Figure 1 SDF-4 Phantom
View) and lift the rear access panel off. The
manifold assembly contains diaphragm air
valves, solenoid valves, the manifold weldment,
and the manifold brackets. See the Replacement
Parts List for authorized Torit replacement
parts.
When replacing the rear access panel, be sure
the gasket is not damaged and the screws are
tight, or leakage may occur.
2.7.2 Blower Compartment (See Figure 1
SDF-4 Phantom View)
Remove the rear access panel as described in
Section 2.8.1 Air Manifold Assembly in order to
access the blower compartment.
2.7.3 Dust Storage Compartment
Access to the dust storage compartment is
through the hinged door on the front of the unit
(see Figure 1 SDF-4 Phantom View). The dust
container and cover are in the dust storage
compartment. The dust container support system
is located at the base of the dust storage
compartment and is removable. The dust
container support system may be lifted from its
two mounting pins and removed through the
dust compartment door.
4.0 START–UP
1. Turn on the compressed air supply to the
Downflo model SDF dust collector
compressed air manifold. Adjust to 90 psig
of pressure, minimum. Pressure of
90-100 psig is the most typical setting for
satisfactory cleaning performance (see
Section 5.0 Operating Adjustments).
The lower the compressed air setting, the
lower the pulse valve air consumption.
2. Turn on the blower motor by pressing the
green BLOWER ON button on the Checker
board diagnostic and control panel.
3. Adjust the blower for the proper system
airflow that is desired by adjusting the
volume control damper on the blower fan
exhaust discharge if applicable (see Figure 1
SDF-4 Phantom View). The outlet damper is
not designed to be used when either the
outlet adapter for ducting or after filtering,
or the weather hood are attached to the
cabinet.
Disconnect the SDF from all electrical
power sources and compressed air supply
and bleed off any residual pressure before
performing any service work.
CAUTION
NOTE
Make sure the dust storage compartment
door is closed tightly. Handles should be
turned clockwise to seal the door properly.
Stand clear of blower fan exhaust area as
debris can be exhausted and cause injury.
CAUTION
