1 RECEIPT OF EQUIPMENT
1.1 INSPECTION
All equipment should be carefully checked for damage or shortages as soon as it is received. Each
shipment should be carefully checked against the bill of lading. If any damage or shortage is evident, a
notation must be made on the delivery receipt before it is signed and a claim should then be filed
against the freight carrier. Inspection and claims are the responsibility of the recipient.
1.2 LOSS OF GAS HOLDING CHARGE
The refrigeration coil section of each Levitor Series II unit is leak tested, evacuated to remove moisture
and then shipped with a pressurized nitrogen gas holding charge. Absence of this charge may indicate
a leak has developed in transit. The system should not be charged with refrigerant until it is verified
that there is no leak, or the source of the leak is located and repaired if necessary.
2 MODELS AND DIMENSIONS
2.1 UNIT MODELS
Units are available with 24” and 30” diameter fans and a variety of motor speeds and horsepower’s. All
units are designed for vertical air discharge, with horizontal air discharge as an option. Each unit is
constructed for the refrigerant and internal working pressure that is indicated on the unit nameplate. All
units contain the UL, cUL, and CSA labels to indicate the unit was manufactured using acceptable
practices by the governing bodies.

3 UNIT LOCATION
The Levitor Series II units require adequate space to allow unrestricted ambient airflow in to and out of
the fan section. Figure 3 gives general rules of the location of an air-cooled condenser in different
situations. The distances shown in the sketches should be increased whenever possible. The unit
position relative to the prevailing winds should be taken into account. Note that higher than expected
head pressures will result in poor system operation if the following suggested distances are not used.
So that the unit performs as predicted it should be located away from heated air exhausts, steam vents,
or corrosive airflow, whether it comes from the job site, or from another nearby source. A corrosive
atmosphere will require an appropriate coil coating, or copper fins to protect the coil and extend the life
of the unit.
Unit location with regard to noise should also be considered. An air-cooled condensing unit should be
located away from noise and vibration sensitive spaces to avoid transmission into workspaces.
Figure 3 LOCATION REQUIREMENTS
Walls or Barriers Multiple Units
For proper airflow and access, all sides of the
unit should be a minimum of “W” away from
any wall or barrier. Enough space should be
allowed for all maintenance work. Overhead
obstructions are not allowed.
For units placed side by side, the minimum
distance between units is the width of the
largest unit. If units are placed end to end, the
minimum distance between units is one fan
section long.
Walls or Barriers for Horizontal Airflow Decorative Fences
Units with horizontal airflow should be a
minimum of “W” away from any wall or barrier,
plus the air discharge should be free flowing
away from the unit.
Fences must have 50% free area, with 1 foot
undercut, a “W” minimum clearance, and must
not exceed the top of the unit.
W = Total width of the air-cooled condensing unit.
