Unit Inspection

WARNING
Fiberglass Wool!
Product may contain 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.
AVERTISSEMENT
Laine de verre!
Le produit peut contenir de la laine de verre. Des
interventions inappropriées sur l'isolation de ce produit
pendant les opérations d'installation, d'entretien ou de
réparation vous exposent à des particules aériennes de
fibres de verre ou de fibres céramiques, responsables
selon la législation américaine (état de Californie) de
risques de cancers par inhalation. Les fibres de verre
peuvent aussi provoquer des phénomènes d'irritation au
niveau du système respiratoire, de la peau ou des yeux.
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.
• 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
OAU-SVX007A-EN
additional respiratory protection. Use the appropriate
NIOSH approved respiration in these situations.

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:
• the unit is stored before it is installed; or,
• 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 startup.
Note: Do not use the unit's heater for temporary heat without
first completing the startup procedure detailed in
Up," p. 92.
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

"Unit Clearances, Curb Dimensions, and Dimensional Data,"
p. 24 contains figures that illustrate 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 or
recirculation of hot condenser air.
