Cold Weather Operation
The compressor will not start if the hydraulic oil temperature is lower
than 5 F (-15 C). Refer to the installation manual for more detailed
information. Observe the following precautions:
if temperatures are below 41 F (5 C), cover the PREDATAIR
during transit (if exposed) and pre-heat by circulating hydraulic
oil through the system before starting the compressor
if temperatures are below 5 F (-15 C), install a cold climate kit
(A700146) and circulate the hydraulic oil through the system
do not allow ice or snow to build up around the air filter and inlet
control valve
Hot Weather Operation
Thermal protection will prevent operation if the temperature is too
high:
If temperatures are above 100 F (37 C), reduce the compressor
duty cycle.
Provide additional hydraulic oil cooling.
Provide proper ventilation if the compressor is inside a cabinet or
enclosure. Cool air results in better performance and higher
CFM.
Hydraulic Oil
Use hydraulic oil that is correctly rated for the operational
temperature range of the equipment.
Automatic Shutdown
If the compressor or hydraulic oil gets too hot, the over-temperature
circuit will disengage the hydraulic system, preventing operation. The
red indicator light will illuminate and the display box will show a
message identifying the problem.
If this problem persists, refer to the troubleshooting section in this
manual.
1. Turn the compressor switch to the “OFF” position.
