Installation Checklist
Complete this checklist as the unit is installed to verify that all
recommended installation procedures are accomplished
before the unit is started. This checklist does not replace the
detailed instruction given in appropriate sections or this
manual. Always read the entire section carefully to become
familiar with the procedures.
Receiving
❑ Unit and components are inspected for shipping damage.
File damage claims immediately with the delivering carrier.
❑ Unit is checked for missing material. Look for ship-with
drives, filters that are packaged separately, placed inside
the main control panel, fan section, or secured to the bottom
of the compressor section.
❑ Check nameplate unit data so that it matches the sales
order requirements.
Unit Location
❑ Crating is removed and cleared form the unit. Do not
remove the shipping skid until the unit is set in its final
position.
❑ Unit Location is adequate for unit dimension and all
ductwork, piping and electrical connections.
❑ Access and maintenance clearances around the unit are
adequate. Allow space at the end of the unit for shaft and
consider servicing.
Unit Mounting
❑ Unit is placed in its final location.
❑ Shipping skid bolts and shipping skid are removed.
❑ Unit properly pitched in direction of drain pan outlet.
❑ Unit properly mounted on isolators (if used).
❑ Compressor and supply fan properly isolated.
❑ Unit protective shipping covers removed.
Component Overview
❑ Fan and motor shafts are parallel.
❑ Fan and motor sheaves are aligned.
❑ Belt tension is properly adjusted.
❑ Fan rotates freely.
WARNING : Disconnect electrical power
source to prevent injury or death from electrical shock.
❑ Locking screws, bearing setscrews and sheave setscrews
are tightened to their proper torques.
❑ Bearing locking collars do not wobble when rotated.
Ductwork
❑ Return ductwork (if used) to the unit is secure, with three
inches of flexible duct connector.
❑ Discharge duct extends upward without change in size or
direction for at least three fan diameters.
❑ Discharge ductwork utilizes a three-inch flexible duct
connection.
❑ Trunk ductwork to terminal units is complete and secured
to prevent leaks.
Controls
❑ Static pressure adjusted. Pressure head assembly is
installed in the discharge duct.
❑ Space temperature sensor is mounted in an area that is
not subjected to drafts of “dead” spots behind doors or in
comers; hot to cold air from duct; radiant heat from the sun
or appliances, concealed pipes and chimneys.
Electrical Wiring
❑ Check for a complete set of wiring diagrams mounted on
the inside of the control panel door.
❑ Supply power (line voltage) is brought through a fused
disconnect switch to the control panel terminal board 2TB.
Check for proper phase sequence.
❑ Check all contactor lugs for tightness.
