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:

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.

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.
