INSTALLATION OF UNIT

ENGLISH
Inspection
1
Check for damage after unit is unloaded.
Report promptly, to the carrier, any
damage found to unit. Do not drop unit.
2
Check the unit nameplate to determine if
the unit voltage is correct for the
application. 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
compartment 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 unobstructed
airflow into the condenser coil and away from
the fan discharge and permit unobstructed
service access into the compressor
compartment. Suggested airflow clearances and
service clearances are given in Figure 1.
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.
Roof Mounted Unit
On new roofs, the curb should be welded
directly to the roof deck. For existing
construction, nailers must be installed under
the curb if welding is not possible. Be sure
attach the down flow ductwork to the curb
before setting unit in place.
When installing the unit, it must be level to
insure proper condensate flow from the unit
drain pan.
Slab Mount
"For ground level installation, the unit base
should be adequately supported and hold the
unit near level. The installation must meet the
guidelines set forth in local codes."
NOTE
!
• The use of "spreader bars" is required
when hoisting the unit (prevents
damage to sides and top). Top crating
can be used as spreader bars.
