CeilAiR OHS Series Installation, Operation & Maintenance Manual
Air Technology Systems, Inc.
WARNING
This unit employs high voltage equipment with
rotating components. Exercise extreme care to
avoid accidents and ensure proper operation.
WARNING
When working on electrical equipment, remove
all jewelry, watches, rings, etc.
WARNING
Refrigerant (R407C or R410A) is used with this
equipment. Death or serious injury may result if
personnel fail to observe proper safety precau-
tions. Great care must be exercised to prevent
contact of liquid refrigerant or refrigerant gas,
discharged under pressure, with any part of the
body. The extremely low temperature resulting
from the rapid expansion of liquid refrigerant
or pressurized gas can cause sudden and ir-
reversible tissue damage.
As a minimum, all personnel should wear ther-
mal protective gloves and face-shield/goggles
when working with refrigerant. Application of
excessive heat to any component will cause
extreme pressure and may result in a rupture.
Exposure of refrigerant to an open fl ame or a
very hot surface will cause a chemical reaction
that will form carbonyl chloride (hydrochloric/hy-
drofl uoric acid); a highly poisonous and corro-
sive gas commonly referred to as PHOSGENE.
In its natural state, refrigerant is a colorless,
odorless vapor with no toxic characteristics. It
is heavier than air and will disperse rapidly in
a well-ventilated area. In an unventilated area,
it presents a danger as a suffocant.
Always refer to the manufacturer’s MSDS pro-
vided with the unit.
WARNING
When performing soldering or desoldering op-
erations, make certain the refrigeration system
is fully recovered and purged and dry nitrogen
is fl owing through the system at the rate of not
less than 1-2 CFM (0.028-0.57 M ³/minute).

CAUTION
Certain maintenance or cleaning procedures
may call for the use and handling of chemi-
cals, solvents, or cleansers. Always refer to
the manufacturer’s Material Safety Data Sheet
(MSDS) prior to using these materials. Clean
parts in a well-ventilated area. Avoid inhalation
of solvent fumes and prolonged exposure of
skin to cleaning solvents. Wash exposed skin
thoroughly after contact with solvents.
CAUTION
Do not use cleaning solvents near open fl ame
or excessive heat. Wear eye protection when
blowing solvent from parts. The pressure-wash
should not exceed 30 psig. Solvent solutions
should be disposed of in accordance with local
and state regulatory statutes.
CAUTION
When the air conditioner is in the cooling mode,
the return air-intake and discharge (supply)
must be free of obstructions. Ensure panels
are secure and latched into position.
CAUTION
DX and chilled water cooling coils (and associ-
ated piping circuits) are pressurized and sealed
when they leave the factory. Before installing
the interconnecting piping, observe appropriate
safety precautions and release the pressure via
an available stem valve or schrader valve prior
to uncapping the pipes.
CAUTION
When installing and fi lling the water/glycol loop,
all air must be bled from the piping system and
the piping system must be cleaned prior to add-
ing the solution. Failure to do so will result in
equipment problems.
WARNING
Do not use chloride based water conditioning
additives in the condensate drain pans. This will
cause corrosion to occur on the coil fi ns.
