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.
•
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.
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. You MUST wear all necessary Personal
Protective Equipment (PPE) including gloves, eye
protection, mask, long sleeves and pants when working
with products containing fiberglass wool. Exposition to
glass wool fibers without all necessary PPE equipment
could result in cancer, respiratory, skin or eye irritation,
which could result in death or serious injury.
Precautionary Measures
•
Avoid breathing fiberglass dust.
•
Use a NIOSH approved dust/mist respirator.
•
Avoid contact with the skin or eyes. Wear long-sleeved,
loose-fitting clothing, gloves, and eye protection.
•
Wash clothes separately from other clothing: rinse
washer thoroughly.
•
Operations such as sawing, blowing, tear-out, and
spraying may generate fiber concentrations requiring
additional respiratory protection. Use the appropriate
NIOSH approved respiration in these situations.
RT-SVX33E-EN
First Aid Measures
•
Eye Contact - Flush eyes with water to remove dust. If
symptoms persist, seek medical attention.
•
Skin Contact - Wash affected areas gently with soap
and warm water after handling.
Storage
Take precautions to prevent condensate from forming
inside the unit's electrical compartments and motors if:
15. The unit is stored before it is installed; or,
16. 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
"Start Up, " p.
The manufacturer will not assume any responsibility for
equipment damage resulting from condensate
accumulation on the unit's electrical and/or mechanical
components.
Unit Clearances
Figure 1, p. 11
illustrates the minimum operating and
service clearances for either a single or multiple unit
installation. These clearances are the minimum distances
necessary to assure adequate serviceability, cataloged
unit capacity, and peak operating efficiency.
Providing less than the recommended clearances may
result in condenser coil starvation, "short-circuiting" of
exhaust and economizer airflows, or recirculation of hot
condenser air.
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.
This module through Proportional/Integral control
algorithms perform specific unit functions that governs
unit operation in response to; zone temperature, supply air
33.
