Section 5: Operation; General; Purpose Of Controls; Starting The Compressor - Sullair 185CFM User Manual

185 T4F Kubota User Manual

5.1 General

While Sullair has built into this compressor a complete
set of controls and indicators that allow the operator to
control and monitor the compressor's operation and per-
formance, operators should learn to recognize indica-
tions which identify a service requirement or conditions
that could lead to (or show) a (current) malfunction.
Before starting the compressor, read this section thor-
oughly to gain familiarity with the controls and indica-
tors—their function and location.

5.2 Purpose of controls

Engine switch
Press this switch to the ON (ignition) position to energize
the electrical system of the compressor. Press the switch
to the START position to momentarily engage the starter
and start the compressor. Press the switch to the OFF
position to shut the compressor down. This switch is
located on the instrument panel.
Regeneration switch
When the regeneration switch is in the REGEN position,
regeneration occurs normally. When the switch is in the
INIHIBIT position, regeneration is prevented. When the
switch is in the FORCE position, regeneration occurs
immediately if the conditions for regeneration are met.
Air pressure gauge
Continuously monitors the pressure inside the receiver tank.
Fluid level sight glass
Indicates the fluid level in the receiver tank. Proper level
is marked halfway up the sight glass. Check the level
when the compressor is shutdown and on level ground.
Compressor discharge temperature switch
Opens the electrical circuit to shut down the compressor
when the discharge temperature reaches the compressor
discharge shutdown temperature (see Section 4.1 on
page 35).

Operation
02250216-781 R02
Subject to EAR, ECCN EAR99 and related export control restrictions.
Thermal valve
Functions as a temperature regulator by directing the com-
pressor fluid either to the cooler or to the compressor unit.
Minimum pressure device
Maintains the minimum of 80 psig (5.6 bar) in the com-
pressor receiver tank.
Pressure relief valve
Vents receiver tank pressure to the atmosphere if pres-
sure inside the receiver tank exceeds 200 psig (13.8 bar).
Air inlet valve
Controls the amount of air allowed to enter the air com-
pressor inlet. Regulation is determined by a signal from
the pressure regulator(s).
Blowdown valve
Vents receiver tank pressure to the atmosphere at shutdown.
Idle warm-up control
Keeps the compressor inlet valve closed for reduced
compressor load at start-up. When the compressor is
warmed-up, the handle is turned from the START to the
RUN position for full operation.

5.3 Starting the compressor

Do not use aerosol types of starting aids such
1
as ether. Such use could result in an explosion
and personal injury.
1
Unless the starting aid is factory-installed or an aftermarket
kit designed specifically for use with the Sullair provided
ether start electrical connector.
1. Ensure that the compressor is on a level surface.
• If the compressor is on an uneven surface,
the fluid sight gauge readings will not be
