Installation
Receiving the Equipment
Your CeilAir TR-OHS system has been tested and
inspected prior to shipment. To ensure the equipment is
received in excellent condition, visually inspect the
equipment immediately upon delivery. Carefully remove
the shipping container and all protective packaging.
Remove the access panels and thoroughly inspect the unit
interior for any signs of transit-incurred damage. If there is
shipping damage, it must be noted on the freight carrier’s
delivery forms before signing for the equipment. Any
freight claims must be done through the freight carrier.
Trane ships all equipment Factory FOB. Trane can assist in
the claim filing process with the freight carrier. Should any
damage be present, notify Trane Product Support prior to
attempting any repairs. Refer to
of
this manual for instructions.
A data package is included with your unit. It contains this
manual, system drawings, applicable material SDSs,
other component manuals, warranty registration and
other applicable instructions based on the configuration
and options provided with the unit. The data package has
been placed in the unit in a clear plastic bag. The
documents need to be retained with the unit for future
reference.
Note:
Items that have been shipped loose, such as
remote sensors, vibration isolators, and so on, are
shipped inside the air conditioner unless specified
otherwise by the customer. Grilles (if applicable)
are placed on top of the air conditioner inside the
unit’s carton. Remove and store these items in a
safe place unless you are using them immediately.
Site Preparation
CeilAir systems are designed with easy service access in
mind. Component access panels are located on the front
and rear sides of the equipment. Additional access to
some components may be obtained through the bottom of
the unit on spot cooler configurations. These units can be
fully serviced in the ceiling plenum. In order to have full
service access, the air conditioner must be located so that
ad- equate space is provided in front of all access panels.
Note:
Working clearance requirements need to be
established prior to the mounting of the unit. Refer
to the National Electrical Code and local codes.
To minimize the effects of the environment surrounding
the conditioned space, certain steps must be taken. This is
especially true for critical/precision room preparation
(computer rooms/labs) requiring close tolerance control
of temperature and humidity. The conditioned space
should be well insulated and include a vapor barrier. The
installer should ensure that the proper insulation rating is
used based on the design of the space that was the basis
for the system selected. The following
is a
recommended minimum R-value (thermal resistance) to
ensure optimum equipment operation.

The vapor barrier is the single most important
requirement for maintaining environmental control in the
conditioned space. The vapor barrier in the ceiling and
walls can be polyethylene film. Concrete walls and floors
should be painted with a rubber or plastic-based paint.
Doors and windows should be properly sealed and a door
sweep used to minimize leakage. Outside or fresh air
should be kept to a minimum (as it adds to the cooling,
heating, dehumidification and humidifying loads), while
maintaining the requirement of the Indoor Air Quality
(IAQ) standard. Lack of these steps can cause erratic
operation, unstable room control and excessive
maintenance costs.
Rigging
WARNING
Heavy Object!
Failure to follow instructions below could result in unit
dropping which could result in death or serious injury,
and equipment or property-only damage.
Ensure that all the lifting equipment used is properly
rated for the weight of the unit being lifted. Each of the
cables (chains or slings), hooks, and shackles used to
lift the unit must be capable of supporting the entire
weight of the unit. Lifting cables (chains or slings) may
not be of the same length. Adjust as necessary for even
unit lift.
NOTICE
Unit Damage!
When moving the unit, it must be kept horizontal and
level to prevent damage.
CeilAir systems are designed to be kept in a horizontal
position. The unit is shipped on a skid to facilitate moving
prior to installation. A suitable lifting device should be
used to lift the unit from the bottom. A weight table is
provided for reference on the installation drawing. The
unit should always be stored indoors in a dry location prior
to installation.
