SAFETY CONSIDERATIONS
SAFETY NOTE
Air-handling equipment will provide safe and reliable
service when operated within design specifications. The
equipment should be operated and serviced only by authorized personnel who have a thorough knowledge of system operation, safety devices and emergency procedures.
Good judgement should be used in applying any
manufacturer’s instructions to avoid injury to personnel
or damage to equipment and property.
time of delivery. Store in a clean, dry, and covered location. Do
not stack cartons. When unpacking units, care should be taken
that the inlet collars and water connections do not become
damaged.
CAUTION
Do not lift the unit by the drain pipes, water piping, or
metal duct. Units should be lifted using the mounting
brackets.
The 36IBAC unit packaging includes a base tray and an inverted box cover. Remove the box cover to fully expose the
unit.
The 36IBAN and 36IBAR units are packaged in cardboard
cartons. Open the carton top and fold the flaps back to gain access to the unit. Two people are required to lift the unit out of
the carton. These units are shipped with the grille attached, and
when setting the unit down, care must be taken to put it on a
clean, soft surface so as not to scratch the grille face.
The 36IBAS, M, L, and J units are packaged in cardboard
cartons. Open the carton top and cut the carton vertically on the
side where the duct collar is located. The grille is attached to
the unit and should not be removed. After cutting the side of
the carton, remove the unit from the box and set it on a clean
surface being careful not to scratch the grille.
Initial Inspection — Once items have been removed
from the carton, check carefully for damage to duct connections, coils, or controls. File damage claim immediately with
transportation agency and notify Carrier.
Installation Precaution — Check that construction de-
bris does not enter unit or ductwork. Accumulated dust and
construction debris distributed through the ductwork can adversely affect unit operation.
Codes — Install units in compliance with all applicable
code requirements.
PREINSTALLATION
GENERAL
The overhead induction beam distribution unit has been designed to give the customer many years of trouble free service.
Each unit contains a row or number of rows of aerodynamic
airflow nozzles located within the 20-gage heavy duty housing
assembly. These airflow nozzles deliver the proper ventilation
air from the main outdoor ventilation unit and produce an airflow profile across the coil. This aerodynamic airflow causes a
venturi effect across the coil face, which induces air from the
room across the coil surface. When cool water or hot water is
pumped through the coil, the induced airflow across the coil is
heated or cooled, then mixed with the primary airflow from the
nozzles to deliver conditioned airflow to the space.
Storage and Handling — Inspect for damage upon re-
ceipt. Shipping damage claims should be filed with shipper at
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Prepare Jobsite for Unit Installation —
time and to reduce the possibility of costly errors, set up a complete sample installation in a typical room at jobsite. Check all
critical dimensions such as pipe, wire, and duct connection requirements. Refer to job drawings and product dimension
drawings as required (see Fig. 1-28). Instruct all trades in their
part of the installation.
Refer to Tables 1-6 and Fig. 1-28 for unit data.
To save
CAUTION
Prior to hanging the unit, remove the two cotter pins holding the supply/return section to the grille frame. Failure to
remove these pins will prevent access to coils and internal
workings of the units.
