"The Plastic Pipe Institute recommends against the
use of thermoplastic pipe to transport compressed
air or other compressed gases in exposed above
ground locations, e.g. in exposed plant piping." (I)
Sullube 32 should not be used with PVC piping sys-
tems. It may affect the bond at cemented joints. Cer-
tain other plastic materials may also be affected.

Adopted January 19, 1972.
2.9 INSTRUMENT PANEL GROUP , FUNCTIONAL
DESCRIPTION-- STANDARD ELECTRO/ME-
CHANICAL
Refer to Figure 2---5 for specific location of parts de-
scribed. The Instrument Panel group consists of a
panel containing the line pressure, sump pres-
sure and discharge temperature gauges, the
separator element and the fluid filter, restriction
gauges, along with START and STOP pushbut-
tons and an hourmeter.
Refer to Figure 2---5 for locations of the following in-
dicators and controls:
The line (terminal) pressure gauge is con-
S
nected to the dry side of the receiver downstream
from the check valve and continually monitors the
air pressure.
WARNING
DESCRIPTION
S The sump pressure gauge continually monitors
the sump pressure at the various load and/or un-
load conditions.
The discharge temperature gauge monitors
S
the temperature of the air leaving the compressor
unit. For both air---cooled and water---cooled com-
pressors the normal reading is approximately
180_F to 205_F (82_C to 96_C).
The separator maintenance gauge monitors
S
condition of the separator element and shows in
the red zone when the element restriction is exces-
sive.
The fluid filter maintenance gauge monitors
S
the condition of the bearing lube filter element and
shows in the red zone when the element should be
changed.
S The START pushbutton turns the compressor on.
S The STOP pushbutton turns the compressor off.
S The hourmeter records accumulative hours of
operation for the compressor and is useful for plan-
ning and logging service operations.
S The red light on the instrument panel indicates
when power to the compressor is supplied.
S The green light indicates when the compressor is
running.
S The HAND/AUTO switch provides selection be-
tween hand operation and automatic control.
