1. Plug the power cord to the appropriate power supply.
Within the rst 10 seconds, the software version will display “1.23,”
followed by the air tank pressure, sequentially.
Example: 85 psig will display as 8-5 [pause]
2. Slowly purge the air tank until the motor powers ON.
3. Allow the air tank to ll (approximately 2–5 minutes).
4. Check for gauge display to reach between 118–120 psig
(8.14–8.27 bar).
TEST PASS:
• The software will automatically power OFF the motor when
the display reads between 118–120 psig (8.14–8.27 bar).
• No air leaks detected.
TEST FAIL:
• The motor does not power OFF when the display reads
between 118–120 psig (8.14–8.27 bar).
• An air leak detected.
• An error buzz sound and error code displays ( “E-r-#” ).
If the test fails, make note of the error code (if present)
and disconnect the power cord from the power supply to
power OFF. Refer to the troubleshooting section (page 8)
for possible corrective action and perform the Test Run
procedure again. If failure persists, contact your Keiser
dealer, distributor, or Keiser Customer Support (see front
cover for contact information).
Air compressor maintenance shall only be performed by
Keiser-certied technicians.
1. Plumbing: Connect a 1/4-inch quick-disconnect (QD) from
the Keiser equipment to any one of the ve QD ports.
A 3/8-inch compression tting port is also available for
3/8-inch air supply congurations (Tools: Adjustable
Wrench and 5/8-inch Wrench).
2. Power Cord: Connect the power cord to the power
connector.
3. Proceed to the Test Run section.
ASSEMBLY
ELECTRIC SHOCK HAZARD
• Install this product where it will not come into contact with
water or other liquids.
• Ensure the power cord is free of damage before connecting
to the power supply.
• If the power cord is damaged, or shows signs of excessive
wear, stop use of the equipment immediately. Do not use
the equipment until the power cord is replaced. Only use
power cords provided by Keiser Corporation.
• This product must be properly grounded. For 120-volt or
220/240-volt circuits, connect power supply cord grounding
plug to a matching grounded outlet. Do not use an adapter
(See diagram below).
• The plug must be plugged into an outlet that is properly
installed and grounded in accordance with all local codes
and ordinances.
• Do not modify the power cord provided. Check with a qualied
electrician or serviceperson if grounding instructions are
not completely understood.
• Failure to follow these instructions can result in death, re
or electrical shock.

ELECTRICAL POWER REQUIREMENTS
Before using the air compressor, check that supply voltage
agrees with that listed on product serial number label or
refer to the Equipment Specications section (page 4).
Low voltage or an overload circuit can cause the overload
protection system circuit breaker to trip.
WARNING
EXPLOSION HAZARD
• Exercise caution when using pressurized air.
• Only use hoses and air ttings provided by the manufacturer.
• Inspect all hoses and ttings for leaks or wear. If leaks or
wear are detected, stop use and replace parts immediately.
Do not use until repairs have been completed and tested
by a Keiser-certied technician.
• Never leave pressurized air in the air tanks when storing
the air compressor or during downtime (maintenance).
• If the air tank develops a leak, replace the air tank
immediately. Never repair, weld or make modications to
the air tanks or their attachments.
• Never make adjustments to the factory-set pressures.
