Pre-Installation; Inspection; Rigging And Handling; Long-Term Storage - Carrier AERO 39MN Installation, Start-Up And Service Instructions Manual

PRE-INSTALLATION

Inspect the unit; file a claim with the ship-
Inspection —
ping company if the unit is damaged. Check the packing list
to ensure that the correct items have been received and notify
your Carrier representative of any discrepancy.
Rigging and Handling —
shipping platform to the storage or installation site, refer to
the rigging label on the unit and these instructions.
CAUTION
A forklift truck cannot be used to move units or compo-
nents. Failure to follow these safety precautions could lead
to personal injury and/or equipment damage.
Base units are shipped fully assembled, except when sec-
tions are separately ordered. All 39M units can be rigged us-
ing the lifting brackets, as shown on the rigging label on the
unit.
1. Lift the unit with slings and header bars, using clevises and
pins in the large round holes in the unit's lifting brackets.
2. When the unit is in its final location, do not remove the
caps from the coil connections until the coil is ready for
piping. Do not remove grease from the fan shaft until
the drive sheave is ready for installation.
Long-Term Storage —
and protect it from weather and construction traffic.
1. The storage site should be level, rigid, and free of de-
bris. If the site is in a heavy rain area, set the unit off of
the ground.

2. Do not store the unit in a heavy traffic area or on a vi-
brating surface. Vibration can damage stationary
bearings.
3. Ensure that all coil connections have shipping caps in
place. Cover the entire unit with a waterproof tarpaulin
or plastic coverall; if the unit is stored on the ground, ex-
tend the cover underneath the unit. Secure the cover
with tiedowns. Do not remove cover or coil end caps un-
til unit is ready for final installation.
4. Monthly — Move the coverall, enter the fan section
through the access door or fan inlet, and slowly rotate
the fan and motor by hand. This operation prevents
bearing corrosion by redistributing the bearing grease.
Service Clearance —
the unit, ensure adequate space for service access. Typical
service operations can require removing the coils and
filters and accessing the motor and damper linkage. Refer to
AHUBuilder ® program for recommended clearances.
Drain Positioning —
sate in the drain pan and ensure proper operation of the drain
system, position the unit so that condensate drain can be
properly trapped. Refer to the Condensate Drain section on
page 89 in the Installation section.
Unit Suspension —
shown in Fig. 5. A field-supplied platform mount is recom-
mended, especially for larger unit sizes. An in-line twin-beam
mount is also recommended. See Fig. 5 and 6. Units can also
be supported by suspending the unit from cross-beams at the
joint between each unit component. Ensure that suspension
rods are secured to adequately support the unit and that the
rods extend entirely through their associated fasteners. Also
ensure that suspension rods do not interfere with service ac-
cess to the unit.
