Start-Up
Start-up checklist
Before starting the equipment, check to see that the following conditions are met:
• All electrical connections comply with national and local codes and safety standards.
• All accessories and ductwork have been installed.
• Air flow to and from the equipment is not blocked.
• The condensate drain is connected and not kinked or pinched.
How to apply power to the equipment
Insert the IEC-320-C19 connector of the power
cord into the back of the equipment. Insert the
opposite end of the power cord, a NEMA 5-20
plug, into the wall outlet. Verify the circuit
breaker is pressed in (flush with the rear of the
equipment), and the green LED on the back of
the plug is on.
Electrical Hazard: Do not use
extension cords with this
equipment. Using an extention cord
reduces circuit protection and voids
the warranty.
Note: If the equipment has been
unplugged or off for less than three
minutes, it waits three minutes before
starting the compressor.
Warning: Route the power cord and the condensate line to prevent accidental injury to
people or damage to the equipment.

Warranty Procedures
Claims
To obtain service under the warranty, contact APC Customer Support (see the back cover of this manual
for contact information). You will need the model number of the Product, the serial number, and the date
purchased. A technician will also ask you to describe the problem. If it is determined that the Product
will need to be returned to APC, you must obtain a returned material authorization (RMA) number from
APC Customer Support. Products that must be returned must have the RMA number marked on the
outside of the package and must be returned with transportation charges prepaid. If it is determined by
APC Customer Support that on-site repair of the Product is allowed, APC will arrange to have APC
authorized service personnel dispatched to the Product location for repair or replacement, at the
discretion of APC.
Parts
• APC warrants the parts of their systems for 1 year from the date of commissioning or 18 months
from the ship date. This warranty only covers the cost of the part and not the labor for installation.
• Calls for warranty parts requests need to have specific unit information (serial number, model
number, job number) to allow proper identification and processing of the warranty part
transaction.
• A purchase order may be required to issue any warranty parts. An invoice will be sent once the
parts are shipped to the field. You have 30 days to return the defective parts to APC. After 30
days, the warranty invoice will be outstanding, and payment of the invoice will be expected in
full.
• Return authorization documentation will be sent with the replacement part. This documentation
must be sent back with the defective part to APC for proper identification of the warranty return.
Mark the warranty return number on the outside of the package.
• After the part has been received at APC, we will determine the status of the credit based on the
findings of the returned part. Parts that are damaged from lack of maintenance, misapplication,
improper installation, shipping damage, or acts of man/nature will not be covered under the parts
warranty.
• Any warranty parts request received before 1:00 PM EST will be shipped same-day standard
ground delivery. Any costs associated with Next Day or Airfreight will be the responsibility of the
party requesting the part.
• Return freight of warranty parts to APC is the responsibility of the party returning the part.
