Step 1 — Inspect Shipment —
Inspect the unit for
damage or missing parts. If damaged, or if shipment is incom-
plete, file a claim immediately with the shipping company.
Step 2 — Position the Unit —
The unit may be
moved by means of rollers under the rails or a forklift truck.
If accessory mobility kit is to be used, install this accessory
after bringing the unit into the building and before moving the
unit to its final location per installation instructions provided
with the accessory. The factory-installed mobility kit option
consists of 6 swivel-type wheels that are field-mounted to the
legs of the unit. See Fig. 20.
NOTE: The wheels are equipped with a thumb-screw brake.

Step 3 — Place the Unit
NOTE: These units are not suitable for unprotected outdoor
use.
Carrier recommends that these units be located in the base-
ment or on the ground floor. However, if it is necessary to lo-
cate the unit on an upper floor, be sure the structure has been
designed to support the unit weight. If necessary, add structural
support to floor. Also, be sure the surface for installation is
level. Refer to Fig. 6-18 for space requirements and weight
distribution.
Only electrical power connections, controls, water connec-
tions for condenser, fluid connections for evaporator, and
strainer installation are required for 30MPW installation. In-
stallation of 30MPA units varies only in field piping required
for the remote condenser instead of a water connection.
When the unit is in its final position, remove the packaging
and remove the mobility kit wheels (if equipped). Remove the
3
/
8
-in. wheel nuts to remove the wheels from the unit legs. Lev-
el the unit (using a level), and bolt the unit to the floor or pad.
If unit is to be mounted on unit external vibration
isolators, follow the mounting instructions included with
the accessory vibration isolator.
If the unit has accessory leveling kit installed, follow the in-
structions provided with the accessory to make sure the unit is
level and in the correct position. The leveling kit is included
with all manifold units.
Step 4 — Check Compressor Mounting
30MP016-030, 040-045 UNITS — As shipped, 30MP016-
030 units with two compressors are held down with six bolts
through rubber grommets. All 30MP040,045 units with three
compressors are held down with eight bolts per pair through
grommets.
After unit is installed, verify that mounting bolt torque is 7
to 10 ft-lb (9 to 14 Nm). See Fig. 21.
30MP032 UNITS — For 30MP032 units, eight RED shipping
bolts must be removed from the compressor mounting rail.
These RED bolts are for shipping purposes only, see Fig. 22.
30MP050-071 UNITS — For 30MP050-071 units, two RED
shipping bolts from the compressor mounting rail must be re-
moved. These RED bolts are for shipping purposes only. See
Fig. 21 — Compressor Holddown Bolts
