Smog-Hog
PSH Series Model
3.5.10 WASH WATER SUPPLY CONNECTIONS
Wash water is required for systems with in-Place
cleaning, refer to the uaS System Layout and the
in-Place cleaning owner’s Manual for installation,
operation and specifications.
3.5.11 ELECTRICAL FIELd INSTALLATION
ELECTRICAL SHOCK HAzARd
When electrical control panels are supplied by
others an electrical interlock should be provided
for the power pack circuit to the Smog-Hog PSH
and the system exhaust blower. This provides
safe operation of the PSH. do not operate the
power pack circuit with the system exhaust
blower off line.
This is an unsafe condition.
all electrical work should be performed by a qualified
electrician in accordance with local electrical codes.
Disconnect electrical power before installing or servicing
electrical components. the PSH is manufactured per
job specifications and uaS specifications, refer to uaS
electrical Drawings. Dashed lines on uaS electrical
Drawings identify field wiring requirements and possible
certain recommended equipment not supplied by
uaS. When additional equipment is specified for field
installation, refer to uaS System Layout Drawing and
uaS electrical Drawings. if the PSH is skid mounted,
interconnection wiring may have been completed at the
factory. Do not mount auxiliary electrical equipment on
or inside uaS equipment unless specifically authorized
by uaS. Such unauthorized action may void the system
warranty. uaS provides solid-state programmable
logic controllers (PLc) on various systems. the PLc
operates on a low (24 VDc/120 Vac voltage and is
susceptible to faults induced by the close proximity to
higher voltage wires. accordingly, the following should
be observed during electrical installation:
1. three-phase leads should not be located within
4 inches of the solid-state controller.
2. care should be exercised when drilling conduit
entry holes to protect PLc and other electrical
components from metal chips and dust. failure
to comply with these instructions can result in a
fault condition requiring repair or replacement
by authorized service personnel. costs of such
repair or replacement are the responsibility of the
user/installing contractor.
THE FOLLOWING SECTIONS ARE
FOR THE USE OF TRAINEd SERVICE
PERSONNEL ONLY.
The PSH unit should be inspected frequently and
collected contaminant removed from the system
regularly to prevent excessive accumulation
which may result in a flashover or risk of fire.
Hazardous live and moving parts are exposed
during the troubleshooting procedures.
Power pack enclosure(s) service voltage is
120VAC. This can be lethal. Voltage 120 VAC is
present within the power pack enclosure even
though the toggle switch is placed in the off
position.
Risk of electrical shock. The high voltage circuits
to the ionizer and collector should be grounded
before removing the power pack, high voltage
wires, door feed through insulators and unicell(s).
The grounding procedure can be accomplished
by waiting one minute after placing the toggle
switch in off position to the power pack enclosure
or refer to Figures 17 and 18. The power pack
total current output is limited to a maximum of
5 milliamps to assure personnel safety.
