Disconnect electrical power at the circuit breaker or fuse box before installing this product.
Install this product where it will not come into contact with water or other liquids.
Install this product where it will be weather protected.
Electrically ground this product.
Failure to follow these instructions can result in death, fire or electrical shock.
WARNING
Electrical Shock Hazard
c
This product must be properly grounded.
Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified electrician.
If repair or replacement of the cord or plug is necessary, do not connect the grounding wire to either flat blade terminal. The wire with insulation that is green with or without yellow stripes is the grounding wire.
Check the condition of the power supply wiring. Do not permanently connect this product to wiring that is not in good condition or is

Plumbing
Remove plugs from the IN and OUT ports. Connect

WARNING
You can follow instructions.
All safety messages will identify the hazard, tell you how to reduce the chance of injury, and tell you what can happen if the safety instructions are not followed.
INSTALLATION
be killed or seriously injured if you don’t
Install relief valves and gauges at inlet or outlet, or both,
o monitor performance. Check valves may be required
t to prevent back streaming through the pump.
Motor Control It is your responsibility to contact a qualified electrician and assure that the electrical installation is adequate and in conformance with all national and local codes and ordinances. Grounding is required.
Determine the correct overload setting required to protect the motor (see motor starter manufacturerʼs recommendations). 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 must be able to withstand the motorʼs starting current. Motor starters with thermal magnetic overload or circuit breakers protect motor from overload or reduced voltage conditions.
The wiring diagram supplied with the product provides required electrical information. Check that power source is correct to properly operate the dual-voltage motors.
Electrical Connection
Correct installation is your responsibility. Make sure
you have the proper installation conditions and that installation clearances do not block air flow.
Blocking air flow over the product in any way can cause the product to overheat.
Mounting
This product can be installed in any orientation. Mounting the product to a stable, rigid operating surface and using shock mounts will reduce noise and vibration.
Injury Hazard
Install proper safety guards as needed.
Keep fingers and objects away from openings and rotating parts.
When provided, motor terminal covers must be in place for safe operation.
Product surfaces become very hot during operation, allow product surfaces to cool before handling.
Air stream from product may contain solid or liquid material that can result in eye or skin damage, wear proper eye protection.
Wear hearing protection. Sound level from motor may exceed 70 dBA.
Failure to follow these instructions can result in burns, eye injury or other serious injury.
WwWARNING
Model with a power supply cord:
Grounded Plug
Grounding Pin
Grounded Outlet
120-volt grounded connectors shown. 220/240-volt grounded connectors will differ in shape.
This product must be grounded. For either 120-volt or
20/240-volt circuits connect power supply cord
2 grounding plug to a matching grounded outlet. Do not use an adapter. (See above diagram.)
In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This product may be equipped with a power supply cord having a grounding wire with an appropriate grounding plug. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances.

OPERATION
Check with a qualified electrician or serviceman if the grounding instructions are not completely understood, or if you are not sure whether the product is properly grounded. Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified electrician.
Model that is permanently wired:
This product must be connected to a grounded, metallic, permanent wiring system, or an equipment grounding terminal or lead on the product.
Power supply wiring must conform to all required safety codes and be installed by a qualified person. Check that supply voltage agrees with that listed on product nameplate.
Extension cords:
Use only a 3-wire extension cord that has a 3-blade grounding plug. Connect extension cord plug to a matching 3-slot receptacle. Do not use an adapter. Make sure your extension cord is in good condition. Check that the gage wire of the extension cord is the correct size wire to carry the current this product will draw.
An undersized cord is a potential fire hazard, and will cause a drop in line voltage resulting in loss of power causing the product to overheat. The following table indicates the correct size cord for length required and the ampere rating listed on the product nameplate. If in
doubt, use the next heavier gage cord. The smaller the gage number, the heavier the wire gage.
It is your responsibility to operate this product at recommended pressures or vacuum duties and room ambient temperatures. This pump is designed to operate up to 25 in. Hg vacuum or 100 PSIG pressure.
Start Up Increase pressure: Check the pressure gauge for
output pressure. Turn the regulator screw in to increase pressure. Maximum pressure is approximately 100 PSI.
Increase vacuum: Check the vacuum gauge for input vacuum. Turn the regulator screw in to increase vacuum. Maximum vacuum is approximately 25 in. Hg.
Maximum pressure and vacuum cannot be produced at the same time.
If motor fails to start or slows down significantly under load, shut off and disconnect from power supply. If the thermal protection switch has tripped, the motor can restart after cooling. Check that the voltage is correct for motor and that motor is turning in the proper direction. Check the plug, cord and switch for damage.
