4.5 COLD WEATHER START-
UP PROCEDURE
When starting the CAS80R Hydraulic Driven
Compressor in cold weather (temperatures
below freezing), there is a chance that over-
pressuring can occur if proper warm-up
procedures are not followed. In a
compressor package, it is normal for
moisture to be present; the amount of
moisture present will vary by use and
ambient conditions. If the compressor is
used in conditions that are subject to
temperatures below freezing (32 degrees
Fahrenheit), it is possible for the moisture to
freeze
within
the
compressor
and
compressor system lines.
For cold weather conditions, please follow
the recommended cold weather start-up
procedure;
In
temperatures
below
15
degrees
Fahrenheit, IMT recommends the installation
of a cold weather package.
1. To utilize the heating pad portion of the
cold weather package, turn on
seasonal switch for at least fifteen
minutes. (Note: This can be done
while driving to the job site.)
2. In all conditions below 32 degrees
Fahrenheit, once at the job site, start the
compressor with service valve partially
open so that the unit is building between
100 PSIG and 125 PSIG on the air
pressure gauge located on the
compressor package.
3. Allow the system to run for at least 10-15
minutes under load to allow the oil time to
warm up for proper lubrication of the
compressor and to allow the moisture to
be evacuated from the compressor and
compressed air lines.
4. At this time, the compressor unit can be
used as intended in accordance with the
safety/operation section of this manual.
5. Immediately after shutting down the
compressor system for extended periods,
drain all FLR systems and air storage
tanks to help minimize the potential for
future system freeze-ups.
6. It is also recommended in cold weather
applications, to drain all lines after each
use.
4.6 ROUTINE SHUTDOWN
PROCEDURE
1. Close service valve and allow
compressor to unload and cool down
(approximately five [5] minutes.).
2. Shut off hydraulic power supply.
4.7 OPERATING CONDITIONS
1 . Operate only in well ventilated areas.
NOTE
Cold weather package system must be
installed at time of compressor package
purchase/initial build.
NOTE
This start-up procedure may not work
in extreme freeze-up conditions. For
this condition, it is best to move the
vehicle into a warm building overnight
to thaw. Once the compressor system
is thawed, follow the start-up procedure
listed above. Allow the compressor to
run at 180 degrees Fahrenheit
according to the compressor package
temperature gauge for at least 15
minutes prior to shutting system down.
WARNING
If the reset button on the instrument panel
has been tripped, NEVER FORCE the
button back into position, or hinder it in
any way, in order to allow for machine
operation. A tripped reset button indicates
a problem that should be addressed and
resolved before operation can continue.
