MAINTENANCE
!
WARNING
: Before performing maintenance, release air
pressure from the compressor using the manual drain
valve (see parts identification 8) and disconnect/lockout/
tagout the main power supply�
WEEKLY MAINTENANCE
■
Drain moisture from your air compressor’s tank
WEEKLY!
!
CAUTION
: Open the drain valve slowly to release the
moisture, as pressure in the tank can cause the moisture
to expel at very high velocity�
■
Check for any unusual noises, vibrations, or permanent
leaks from the unloader valve�
BIANNUAL MAINTENANCE
■
TURN OFF POWER and check and tighten all electrical
connections�
■
Change air-intake filter(s)� The filter is located on the
top of the compressor (see parts identification item 1)�
Twist the top cap off of the filter housing to access the
filter�
■
Check to make sure all bolts are tight�
VALVES AND SWITCHES
PRESSURE RELIEF VALVE (safety valve - see
parts identification 3)
Pressure-relief valves are standard on all units� Pressure-relief
valves aid in preventing system failures by relieving system
pressure when compressed air reaches a determined level�
Pressure-relief valves are PRESET by the manufacturer:
under no
circumstances should the setting be changed by anyone other
than the manufacturer�
!
DANGER
: Pressure-relief valves are designed to protect
compressed-air systems in accordance with ASME B19
safety standards�
PRESSURE SWITCH (S280/S163/S253/S418)
/ DIGITAL AMD (S281/S164/S110) (see parts
identification 2 & 10)
A pressure switch or Digital AMD are standard on all C-Aire
compressors� These are used to detect the demand for
compressed air and allow the motor to start� When the demand
is satisfied, the motor stops� They are both preset at the factory
by C-Aire and do not require adjustment� However, if you want to
make adjustments to the Digital AMD, those instructions are on
page 5�
!
DANGER
: Electric power always exists inside the
pressure switch/digital AMD whenever the compressor is
connected to a power supply� Do not touch any electrical
leads or electric components without locking out the
power supply first�
