2.2 SITE PREPARATION
2.0 INSTALLATION
2.1 Receiving the Equipment
The CeilAir 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 signs of transit-incurred damage. If shipping damage occurred, it must be noted on the freight carrier’s
delivery forms before signing for the equipment. Freight claims must be submitted to the freight carrier.
STULZ ships all equipment factory free on board (FOB). STULZ Product Support can assist in the claim
filing process with the freight carrier. Should any damage be present, notify STULZ Product Support prior to
attempting any repairs (see section 5.0).
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 Loose Shipped Parts
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.
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. Some components may also be accessed 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, install the air conditioner with adequate space in front of all access panels.
NOTE Clearance
Working clearance requirements need to be established prior to the mounting of the unit. Refer to the
National Electrical Code and local codes.
Critical/precision rooms (like computer rooms or labs) require close tolerance control of temperature and
humidity. There are steps one should take to minimize inefficiencies around the conditioned space like
installing insulation and vapor barriers. The installer should base the insulation rating (R-value) on the space
that unit was selected to cool. Table 2 recommends minimum R-values (thermal resistance) to ensure
optimum equipment operation.
