!wAmG!
Never remove, bypass or tamper with the HAT
switch. Bypassing or removing this safety feature
may cause severe personal injury, death, and
property damage. If the compressor shuts down
due to high discharge temperature, contact a
qualified serviceman immediately.
!wARN~G!
High A]r Temperature Light --
indicates when the
unit has sensed an unusually high temperature in the
discharge air/fluid mixture and the unit has shut
down. shutdown.
Indicators
Main Power On Light –
Indicates when power from
the main disconnect switch has been turned on and
there is live power at the compressor starter and control
panel. This light will remain on as long as there is
power to the unit, regardless of the position of the
control selector switch.
Hourmeter --
Indicates actual hours of operation. Used
to determine maintenance intervals.
Air Pressure Gauge --
Indicates the receiver pressure
available for distribution to the service lines.
Air Outlet Temperature Gauge --
Indicates the
temperature of the air/fluid mixtures as it discharges
from the compressor. Normal reading 175° to 200°
degrees F.
Fluid Filter Change Indicator --
Indicates the pressure
differential across the fluid filter is excessive. Used to
determine fluid filter change intervals.
Air/Fluid Separator Differential Indicator --
Indicates pressure dilTerential across the air-fluid
separator element. Used to determine separator element
change intervals.
Percent Capacity Gauge --
This gauge is graduated in
percent
of the total capacityof the unit, Readings taken
from this gauge give an indication of the amount of
capacity the unit is producing.
