Safety Messages

Safety is important to us. We have included safety messages
throughout this manual and for your protection. Please read and follow
all directions.

A safety message has a safety alert symbol
followed by an explanation of what the hazard
is, what can happen and what you should do
to avoid injury. This is the safety alert symbol:

The safety alert symbol and "WARNING" or "CAUTION" will precede
all safety messages:

ELECTRICAL SHOCK HAZARD

Disconnect electrical power at the circuit breaker or fuse box before
installing this product. Install where it will not come into contact with
water or other liquids and where it will be weather protected. Electrically
ground this product. Failure to follow these instructions can result in
death, fire or electrical shock.

Guidelines for Product Use

• Pump only clean, dry, atmospheric air.

• Operate at 32–104°F (0–40°C).

• Protect unit from dirt, foreign material and moisture.

• Never lubricate oilless air compressors.

Operation Guidelines

Installation

Make sure the wiring is done by a qualified electrician familiar with
NEMA MG2 safety standards, national electric code and all local safety
codes. Select fuses, motor protective switches or thermal protective
switches to provide protection. Fuses act as short circuit protection for
the motor, not as protection against overload. Incoming line fuses help
to withstand the motor's starting current. Motor starters with thermal
magnetic overload or circuit breakers protect the motor from overload
or reduced voltage conditions. The wiring diagram attached to the
product provides required electrical information.

Make sure that installation clearances do not block air flow. Blocking air
flow over the product in any way can cause the product to overheat.

WARNING

You will be killed or seriously injured if you don't follow
instructions.

CAUTION

You can be killed or seriously injured if you don't follow
instructions.

• Do not pump flammable or explosive gases or use in an atmosphere
that contains such gases.

• Protect all surrounding items from exhaust air. This exhaust air can
become very hot.

• Corrosive gases and particulate material will damage the unit. Water
vapor, oil-based contaminants or other liquids must be filtered out.

• Do not flush with kerosene or other combustible solvents.
