NOTE
Slowly remove fill cap to vent compressor
sump pressure.
• DO NOT use the compressor for purposes oth-
er than for which it is intended. High pressure
air can cause serious and even fatal injuries.
• DO NOT operate the compressor outside of its
specified pressure and speed ratings. (See
Section 2: Specifications or refer to the equip-
ment data plate.).
• DO NOT use flammable solvents or cleaners
for cleaning the compressor or its parts.
• DO NOT operate the compressor in areas
where flammable, toxic, corrosive fumes, or
other damaging substance can be ingested by
the compressor intake.
• Keep arms, hands, hair and all other body parts,
and clothing away from fans, drive shafts, and
other moving parts.
• DO NOT wear jewelry, unbuttoned cuffs, ties,
or loose-fitting clothing when you are working
near moving/rotating parts.
• ALWAYS confine long hair when working near

• DO NOT use tools, hoses, or equipment that
have maximum ratings below that of this com-
pressor.
• Keep metal tools, and other conductive objects
away from live electrical components.
• Before performing maintenance or repair oper-
ations on the compressor, ensure that all pow-
er has been removed and been locked out to
prevent accidental application.
• DO NOT assume that because the compressor
is in a STOPPED condition that hydraulic pow-
er has been removed.
• Use this compressor only to compress atmo-
spheric air. Use of this equipment as a booster
pump and/or to compress any other gaseous
or aerosol substance constitutes improper
use. It can also cause damage or injuries.
Such misuse will also void the warranty.

3.2 GENERAL INSTRUCTIONS
This section provides general guidance for lo-
cating and preparing the CAS40PL compressor
package for operation. Each installation is unique
and can be affected by location, ventilation, and
other factors such as electrical and hydraulic
power supply availability and location.
DISCLAIMER
DO NOT install in any enclosed space without
first contacting IMT.
WARNING
Install, operate, and maintain this equipment in
full compliance with all applicable OSHA, other
Federal, state, local codes, standards, and regu-
lations.
WARNING
Before performing maintenance or repair oper-
ations on the compressor, ensure that all power
has been removed and locked out to prevent
accidental start-up.
DO NOT assume that because the compressor
is in a STOPPED condition that power has been
removed.
WARNING
DO NOT perform any modifications to this
equipment without prior factory approval.
WARNING
DO NOT use plastic pipe, or incorrectly rated
piping or hose. Incorrectly rated connection
material can fail and cause injury or equipment
damage.
WARNING
DO NOT operate the compressor in enclosed or
confined spaces where ventilation is restricted
or closed off.
NOTE
Install electrical components (circuit breakers,
pressure switches, toggle switches, etc.) in
locations where exposure to water or moisture
will be most minimized.
NOTE
In order to prevent accidental damage to vehi-
cle components (fuel tanks, lines, brake lines,
wiring harnesses), note their location before
drilling any holes.

3.3 DETERMINING THE CAS40PL
UNIT MOUNTING LOCATION
When determining the location to mount the
CAS40PL unit, the following criteria must be tak-
en into consideration:
• The mounting surface must be level and able to
accommodate the four (4) mounting bolts and
isolators of the base frame. Refer to Figure
3-1 or Figure 3-2 for layout of mounting hole
slots’ locations.
IMPORTANT
Mounting surface must be able to bear the
weight of the machine (255-260 lbs, wet).
• Mount the machine with a minimum of four (4)
mounting locations.
• The location must allow for the machine dimen-
sions, and additional space requirements for
minimum cooling, maintenance and access.
Refer to Figure 3-3 to determine the additional
minimum space requirement measurements.
• The external gauges/display must be easily
visible to the operator.
It is recommended, for most installations, to
mount the compressor on the driver’s side of the
vehicle. The unit should be situated in such a
manner that the fan (rear) and hydraulic cooler
(front) are not obstructed. Do not place the com-
pressor in any location where it can ingest ex-
haust fumes, dust or debris.
NOTE
When considering external system layout hoses
refer to Section 7.22, Hose Guide for proper
routing and mounting practices.
3.4 HYDRAULIC SYSTEM
OVERVIEW
IMPORTANT
IMT®highly recommends consulting a hydraulic
supply expert for specifying the correct hydrau-
lic supply components for vehicle-side integra-
tion (including oil reservoir size, hydraulic pres-
sure relief, hose size, etc.) for your application.
IMPORTANT
Contaminated hydraulic fluid allowed to enter
the pump will cause malfunction of the pump
controls. Hydraulic system hoses must be
flushed and cleaned prior to being connected to
the unit.
Refer to Figure 3-1 or Figure 3-2 for hydraulic
pump system connections.
Please take into consideration the following:
• The hydraulic flow and pressure requirements
of the system.
• A continuous hydraulic load is necessary when
compressor is running.
• The duty cycle and ambient operating tempera-
tures.
• Other hydraulic equipment which may share
that same hydraulic supply system (IMT rec-
ommends a dedicated pump and hydraulic
circuit).
WARNING
Follow all applicable safety recommendations
as outlined in Section 1: Safety of this manual.
WARNING
Improperly, or non-connected lines may cause
harm, and will damage the equipment.
The hydraulic hoses must be run to the machine.
Verify that hoses are hooked up properly to en-
sure proper flow. Also, verify that the hoses are
laid out properly so that no chafing or kinking
of the hoses is possible. Refer to Section 7.22,
Hose Installation Guide, for assistance with
proper hose layout and connecting functions.
NOTE
The temperature of the hydraulic oil should not
exceed 160°F due to the rating of the IMT- sup-
plied hydraulic motor.

the hydraulic oil return line. Flow rating of the fil-
ter must be equal to, or greater than, the maxi-
mum GPM at which the system will be operated.
IMPORTANT
Use only a filter that is specifically intended for
hydraulic systems.
3.4.2 HYDRAULIC OIL RESERVOIR
3.4.2.1 DETERMINING RESERVOIR
SIZE
In a conventional hydraulic system, minimum
tank size, in gallons, should be equal to the max-
imum GPM flow rate, times two (x 2).
3.4.2.2 DETERMINING
RESERVOIR SHAPE
The reservoir structure should be tall and narrow
rather than shallow and broad (Figure 3-4). A tall,
narrow tank is recommended because:
1. The oil level is well above suction line open-
ing, avoiding the possibility of drawing air into
the pump due to a vortex or “whirlpool” effect
within the tank during operation flow.
2. Allows for better oil level tolerance level of
the system if vehicle operates at an unusual
(slightly offlevel) vehicle angle.
3. To keep return flow well below the surface so
it does not break the surface and cause aer-
ation (cavitation) of the oil.
3.4.2.3 MANDATORY RESERVOIR
FEATURES
• The reservoir should incorporate the following
design features:
• In terms of location of the reservoir tank within
the hydraulic system, note that the hydraulic
pump’s inlet line (suction line out from the res-
ervoir to the pump) should be located near the
bottom of the tank, well below the oil level. The
suction line should protrude a minimum of two
(2”) inches into the reservoir to keep it away
from potential contaminant surface buildup.
