General Information
WARNING
Fiberglass Wool!
Product contains fiberglass wool. Disturbing the
insulation in this product during installation,
maintenance or repair will expose you to airborne
particles of glass wool fibers and ceramic fibers known
to the state of California to cause cancer through
inhalation. Glass wool fibers may also cause
respiratory, skin or eye irritation.
Jobsite Inspection
Always perform the following checks before accepting a
unit:
• Verify that the nameplate data matches the data on the
sales order and bill of lading (including electrical data).
• Verify that the power supply complies with the unit
nameplate specifications.
• Visually inspect the exterior of the unit, for signs of
shipping damage. Do not sign the bill of lading
accepting the unit(s) until inspection has been
completed. Check for damage promptly after the
unit(s) are unloaded. Once the bill of lading is signed at
the jobsite, the unit(s) are now the property of the
SOLD TO party and future freight claims MAY NOT be
accepted by the freight company.
• Verify that the refrigerant charge has been retained
during shipment by use of gauges. Access fittings are
located internal to the cabinet on the 5-ton through 20-
ton equipment.
• After assuring that charge has been retained, reinstall
the caps to assure that refrigerant leakage does not
occur.
CAUTION
Microbial Growth!
Wet interior unit insulation can become an
amplification site for microbial growth (mold), which
may cause odors and damage to the equipment and
building materials. If there is evidence of microbial
growth (mold) on the interior insulation, the insulation
should be removed and replaced prior to operating the
system.
Jobsite Storage
This unit is intended for indoor use only. To protect the unit
from damage due to the elements, and to prevent possible
IAQ contaminant sources from growing, the unit should be
stored indoors. If indoor storage is not possible, the
following provisions for outdoor storage must be met:
• Place the unit(s) on a dry surface or raise above the
ground to assure adequate air circulation beneath the
unit.
• Cover the unit(s) with a waterproof tarp to protect them
from the elements.
• Make provisions for continuous venting of the covered
units to prevent moisture from standing on the unit(s)
surfaces. Wet interior unit insulation can become an
amplification site for microbial growth (mold) which
has been determined to be a cause of odors and
serious health related indoor air quality problems.
• Store units in the normal UP orientation to maintain oil
in the compressor.
• Do not stack more than three units in total height for
the EXWE 5 and 10-ton configurations, and no more
than two units high for the EXWE configuration.
Unit Nameplate
The unit nameplate is located at the front of the unit. It
includes the unit model number, serial number, electrical
characteristics, refrigerant charge, and other pertinent unit
data.
Compressor Nameplate
The nameplate for the compressors are located on the
compressor shell.
Unit Description
Before shipment, each unit is leak tested, dehydrated,
charged with refrigerant and run tested for proper control
operation.
Water-to-Refrigerant Coils
The water-to-refrigerant heat exchangers are an inner
copper tube or cupro-nickel (option available on the
source-side only) and steel tube (tube-within-a-tube)
design and are leak tested to assure there is no cross
leakage between the water and refrigerant gas.
Water Connections
Water connections are located inside the unit and are
accessible from the back of the unit. The fitting is a female
pipe threaded connection. The size of the connection is 1”
for the 5 ton, 1½” for the 10 ton and 2” for the 20 ton unit.
Controls
The control system offered to control the unit is a deluxe
24 volt micro processing board.
All power wiring to the equipment is made at the power.
All low voltage wiring is made at the unit’s low voltage
terminal board.
Wiring Connections
Troubleshooting and connection diagrams for the
equipment may be located in the back of this manual.
