VIAIR 444C Dual - Manual (Page 4)

OPERATING INSTRUCTIONS
1. IMPORTANT: Always operate the compressors at or below the MAXIMUM PRESSURE RATING
of the compressor (200 PSI).
2. Always observe the MAXIMUM DUTY CYCLE of the air compressor. Refer to Compressor
Applications and Specifications Sections of this manual for details. Operation exceeding
maximum pressure ratings and/or duty cycle will result in damage to the air compressor.
3. Your air compressors are equipped with AUTOMATIC THERMAL OVERLOAD PROTECTORS.
This feature is designed to protect the air compressor from overheating and causing permanent
damage. The thermal overload protector will automatically cut power to your air compressor
should the internal operating temperature of the air compressor rise above safe levels during
excessive use.
4. Should at any time during use, your air compressors automatically shut off, do not attempt
to restart them. Cut power to the air compressor. The automatic thermal overload protector
will automatically reset when internal temperature of the air compressor drops below safe levels.
After allowing air compressor to cool off for about 30 minutes, you can safely resume use of the
air compressor.
5. To prevent discharge of your vehicle’s battery, we recommend that you keep the vehicle’s engine
running while operating air compressors.
6. ONLY OPERATE AIR COMPRESSORS IN WELL-VENTILATED AREAS.
7. Compressor performance is enhanced when operating compressor with vehicle’s engine running.
8. INSTALLATION TIP:
Always plumb your system using a separate tank port for each compressor leader hose.
This can improve flow performance.
MAINTENANCE & REPAIRS
1. Periodically check all electrical, fittings connections. Clean and tighten as needed.
2. Periodically check all mounting screws. Tighten as needed.
3. Replace Air Filter Element periodically. Replacement frequency depends on operating frequency
and operating environment. For frequent use in dusty environments, we recommend that you
replace air filter element once a month.
4. Regularly clean dust and dirt from compressor cooling fins and motor housing.
5. Your air compressor is equipped with a permanently lubricated, maintenance-free motor.
Never try to lubricate the compressor.
6. All repairs should be performed by Manufacturer or Manufacturer’s Authorized
Service Agencies only.
CAUTION:
Never touch the air compressor or fittings connected to the air compressor with bare hands during
or immediately after use. The leader hose and fittings connected to leader hose will become very
HOT during and after use. If necessary, wear heat resistant gloves to handle fittings, air line, and
leader hose.
