General Information
Unit Inspection
As soon as the unit arrives at the job site
•
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, including the
roof, for signs of shipping damage.
If the job site inspection of the unit reveals damage or
material shortages, file a claim with the carrier
immediately. Specify the type and extent of the damage on
the “bill of lading” before signing.
•
Visually inspect the internal components for shipping
damage as soon as possible after delivery and before
it is stored. Do not walk on the sheet metal base pans.
•
If concealed damage is discovered, notify the carrier’s
terminal of damage immediately by phone and by
mail. Concealed damage must be reported within 15
days.
•
Request an immediate joint inspection of the damage
by the carrier and the consignee. Do not remove
damaged material from the receiving location. Take
photos of the damage, if possible. The owner must
provide reasonable evidence that the damage did not
occur after delivery.
•
Notify the appropriate sales representative before
installing or repairing a damaged unit.
Storage
Take precautions to prevent condensate from forming
inside the unit’s electrical compartments and motors if:
1.
the unit is stored before it is installed; or,
2. the unit is set on the roof curb, and temporary heat is
provided in the building. Isolate all side panel service
entrances and base pan openings (e.g., conduit holes,
S/A and R/A openings, and flue openings) from the
ambient air until the unit is ready for start-up.
Note:
Do not use the unit’s heater for temporary heat
without first completing the start-up procedure
detailed under “Starting the Unit”.
The manufacturer will not assume any responsibility for
equipment damage resulting from condensate
accumulation on the unit’s electrical and/or mechanical
components.
Model Number Description
All products are identified by a multiple-character model
number that precisely identifies a particular type of unit. Its
use will enable the owner/operator, installing contractors,
and service engineers to define the operation, specific
components, and other options for any specific unit.
When ordering replacement parts or requesting service,
be sure to refer to the specific model number and serial
number printed on the unit nameplate.
Overview of Manual
Note:
One copy of this document ships inside the control
panel of each unit and is customer property. It must
be retained by the unit’s maintenance personnel.
This booklet describes proper installation, operation, and
maintenance procedures for air cooled systems. By
carefully reviewing the information within this manual
and following the instructions, the risk of improper
operation and/or component damage will be minimized.
It is important that periodic maintenance be performed to
help assure trouble free operation. A maintenance
schedule is provided at the end of this manual. Should
equipment failure occur, contact a qualified service
organization with qualified, experienced HVAC technicians
to properly diagnose and repair this equipment.
Unit Nameplate
A Mylar unit nameplate is located on the unit’s corner
support next to the filter access panel. It includes the unit
model number, serial number, electrical characteristics,
refrigerant charge, as well as other pertinent unit data.
Compressor Nameplate
The nameplate for the compressors are located on the side
of the compressor.
Unit Description
Before shipment, each unit is leak tested, dehydrated,
charged with refrigerant and compressor oil, and run
tested for proper control operation.
The condenser coils are aluminum fin, mechanically
bonded to copper tubing.
Direct-drive, vertical discharge condenser fans are
provided with built-in thermal overload protection.
The ReliaTel™ Control Module is a microelectronic control
system that is referred to as “Refrigeration Module”
(RTRM). The acronym RTRM is used extensively
throughout this document when referring to the control
system network.
These modules through Proportional/Integral control
algorithms perform specific unit functions that governs
unit operation in response to; zone temperature, supply air
temperature, and/or humidity conditions depending on
the application. The stages of capacity control for these
units are achieved by starting and stopping the
compressors.
The RTRM is mounted in the control panel and is factory
wired to the respective internal components. The RTRM
receives and interprets information from other unit
