The UMA controller operates the fan and shaker in the
proper sequence to ensure effective filter cleaning. The
controller contains an across-the-line fan starter and an
across-the-line shaker motor starter.
1. Mount the controller in a convenient accessible
location, free of vibration and temperature extremes.
Do not mount the controller
directly to the collector.
Mechanical vibration can damage the control.
2. Using the wiring diagram supplied with the controller,
connect the power lead from a customer-supplied
disconnect switch to the terminal block inside the
controller, complying with all applicable codes for
motor branch circuits.
3. Install conduit from the controller to the junction box
located on the side of the collector. Use conduit and
fittings compatible with the rating of the controller’s
enclosure.
4. Make the connections from the manual motor
protector inside the controller to the terminal block in
the junction box.
UMA Controller
The UMA Controllers are designed to work with three-
phase, 50- or 60-Hz power supplies or optional single-
phase power.
Inlet Assembly
All models are shipped with the inlet specified at the
time of order. Side inlets are not interchangeable with
back inlets. Contact Pakzy if additional changes are
necessary.
1. Remove the inlet blank from the specified location.
2. Replace damaged sealant if necessary.
3. Secure inlet to collector using the hardware
removed in Step 1.
All electrical wiring and connections, including electrical
grounding, should be made in accordance with the
National Electric Code (NFPA No. 70-latest edition).
Check local ordinances for additional requirements that
apply.
The appropriate wiring schematic and electrical rating
must be used. See collector’s rating plate for required
voltage.
An electric disconnect switch having adequate amp
capacity shall be installed in accordance with Part IX,
Article 430 of the National Electrical Code (NFPA No.
70-latest edition). Check collector’s rating plate for
voltage and amperage ratings.
Refer to the wiring diagram for the number of wires
required for main power wiring and remote wiring.
Mount controller outside the influence area of any
explosion relief panels, if present.
Electrical installation, service,
or maintenance work must
be performed by a qualified electrician and
comply with all applicable national and local
codes.
Turn power off and lock out all power before
