2.0 INSTALLATION
2.1 Receiving the Equipment
Your FLAiR 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 immediately upon delivery.
Carefully remove the shipping container and all
protective packaging. Open 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, a supplemental microprocessor
controller manual, system drawings, applicable
MSDS’s, other component manuals, warranty registra-
tion and other applicable instructions based on the
configuration and options of your unit. The data
package has been placed in your unit in a clear plastic
envelope. These documents need to be retained with
the unit for future reference.
NOTE
Items that have been shipped loose, such as
controllers, temperature sensors, water detec-
tors etc., are shipped inside the air conditioner,
unless specified otherwise by the customer.
Remove and store these items in a safe place
unless you are using them immediately.
2.2 Site Preparation
The
FLAiR systems were designed with easy service
access in mind. Component access panels are
located on the front of the unit. In order to have full
service access through the front, no permanent
obstructions can be placed within 30 inches in front of
units ranging from 18,000 to 36,000 BTU/Hr and 40
inches in front of 60,000 BTU/Hr. units, (see Figure 1).
NOTE
Working clearance requirements need to be es-
tablished 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 temperature and humidity control. The
conditioned space should be well insulated and should
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 recom-
mended 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 a 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
The
FLAiR systems are designed to be kept in the
vertical position. Move the unit with a suitable device
such as a forklift, roller bar, pallet jack or dollies. For
reference, a weight table is provided on the installation
drawing. Units are shipped on a skid to facilitate
moving prior to installation. Units should always be
stored indoors in a dry location prior to installation.
