CeilAiR OHS Series Installation, Operation & Maintenance Manual

ir Technology Systems, Inc.

2.0 Installation

2.1 Receiving the Equipment

Your

CeilAiR

OHS system has been tested and

inspected prior to shipment. To ensure that your

equipment has been received in excellent condition,

make a visual inspection of the equipment immedi-

ately 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. SATS ships all equipment FOB.

SATS can assist in the claim filing process with the

freight carrier. Should any damage be present, notify

the SATS Product Support Group prior to attempting

any repairs. Refer to section five of this manual for

instructions.

A unit Data Package has been sent with your unit. It

contains this manual, system drawings, applicable

MSDS’s, other component manuals and any other

applicable instructions based on the configuration and

options of your unit. The data package has been

affixed to your unit in a clear plastic bag. These

documents need to be kept with the unit for future

service.

NOTE

Items that have been shipped loose such as con-

trollers, humidistats, vibration isolators, buck/

boost transformers, etc. 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 car-

ton. Remove and store these items in a safe

place unless you are using them immediately.

2.2 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 adequate

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 local and national electrical 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, which was the basis for the system selected.

The following chart is a recommended minimum R-value

(thermal resistance) to ensure optimum equipment

operation.

The vapor barrier is the single most important require-

ment 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.

2.3 Rigging

CeilAiR

systems are designed to be kept in the

horizontal position. Lift the unit from the bottom with a

suitable lift device. A weight table is provided for

reference on the installation drawing. The unit is

shipped on a skid to facilitate moving prior to installa-

tion. A suitable lifting device should be used when

moving equipment. The unit should always be stored

indoors in a dry location prior to installation.
