Smog-Hog
PSH Series Model
failure to achieve in Place cleaning specifications will
result in an ineffective wash cycle, increasing system
maintenance costs. if the PSH is located outside and
there are climate associated problems (32°f or below),
exposed piping wash/drain including solenoid valves
should be heat traced and insulated. Do not heat trace
the solenoid valve coil.
2.3.4 dUCTING
Quality ducting is important system performance.
Sealed connections prevent air and liquid leakage
during operation. Welded duct connections are
required with ducting pitched towards the PSH.
Duct design air velocities are typically 1,500 to 2,500
fPM. Gaskets and sealant, where used, should
be compatible with the material collected and the
temperature of the airstream. Wet airstreams (high
humidity) typically require insulation to prevent
condensation.
3. INSTALLATION
CRUSH ANd ELECTROCUTION HAzARd
Use adequate safety measures when lifting and
assembling heavy components. Consult site
safety personnel for recommendations. Location
should be clear of all obstructions, such as
utility lines and building clearances.
2.3 Supports
2.3.1 SKIddEd SYSTEMS
Lifting points for skid mounted PSH systems are
illustrated to the uaS System Layout Drawings
including installation notes. field structural support
design is the responsibility of the installer. Good design
practice should be followed in allowing adequate
clearance for plumbing, conduit installation, and
maintenance.
2.3.2 UNSKIddEd SYSTEMS
When PSH components are shipped unassembled, care
should be taken to provide adequate bearing support on
the field support structure.
ducting and accessories attached to the PSH
unit should be independently supported.
2.3.3 UTILITIES/dRAINS
Mechanical, electrical service requirements and system
entry points are clearly marked on the uaS System
Layout Drawing and uaS electrical Drawings. the PSH
main drain pipe should be have a drain trap. refer
to figure 6. When a PSH is equipped with in Place
cleaning, operating water pressure (working pressure),
flow rates (gpm) and hot water specified are based on
factory testing, refer to uaS System Layout Drawing or
in Place cleaning owner’s Manual for specifications.
