INSTALLATION OF UNIT
Inspection
1
Check for damage after unit is unloaded.
Report promptly, to the carrier, any dam-
age found to unit. Do not drop unit.
2
Check the unit nameplate to determine if
the unit voltage is correct for the applica-
tion. Determine if adequate electrical
power is available. Refer to the application
specifications.
3
Check to be sure the refrigerant charge
has been retained during shipment.
Access to 1/4" flare pressure taps may be
gained by removing compressor compart-
ment access panel.
Location and
Recommendations
Unit Support
If unit is to be roof mounted check building
codes for weight distribution requirements.
Location and Clearances
Installation of unit should conform to local
building codes and the National Electrical
Code. Select a location that will permit unob-
structed airflow into the condenser coil and
away from the fan discharge and permit unob-
structed service access into the compressor
compartment. Suggested airflow clearances
and service clearances are given in Figure 1A.
Placing and Rigging
Rig the unit using either belt or cable slings.
The sling eyelet must be placed through the
lifting holes in the base rail of the unit. The
point where the slings meet the lifting eyelet
should be at least 1.8m above the unit. Use
spreader bars to prevent excessive pressure
on the top of the unit during lifting.
NOTE
!
• The use of "spreader bars" is required
when hoisting the unit (prevents dam-
age to sides and top). Top crating can be
used as spreader bars.
INSTALLATION OF UNIT
Lifting beam
Holes in base rail
Roof Mounted Unit
On new roofs, the curb should be welded
directly to the roof deck. For existing construc-
tion, nailers must be installed under the curb if
welding is not possible. Be sure attach the
down flow ductwork to the curb before set-
ting unit in place.
When installing the unit, it must be level to
insure proper condensate flow from the unit
drain pan.
