Heatcraft Refrigeration Products REMOTE AIR-COOLEDCONDENSER 2500018 - Manual (Page 3)

The condenser should be located no closer than four feet from
any wall or other obstruction to provide sufficient clearance
for air entrance. Do not attach ductwork to the coil inlet or fan
outlet. Care should be taken to avoid air recirculation conditions
that can be caused by sight screening, walls, etc. Keep unit fan
discharge away from any building air intakes.
Space and Location Requirements
The most important aspect in selecting a location for air-cooled
equipment is a supply of ambient air to the condenser and the
adequate removal of heated air from the condenser area. If
the requirement for adequate air circulation is not adhered to,
higher head pressures will result, creating poor operation and
possible failure of equipment. Units must not be located in the
vicinity of steam, hot air or fume exhausts.
Walls or Obstructions
The unit should be located so that air may circulate freely and
not be recirculated. For proper air flow and access, all sides of
the unit should be a minimum of the width of the unit away
from any wall or obstruction. It is preferable for this distance
be increased whenever possible.
Care should be taken to see that ample room is left for
maintenance through access doors and panels. Overhead
obstructions are not permitted. When the unit is in an area
where it is enclosed by three walls the unit must be installed
as indicated for units in a pit.
Units In Pits
The top of the unit should be level with the top of the pit and
side distance increased to two times the width of the unit.
If the top of the unit is not level with the top of pit, discharge
cones or stacks must be used to raise discharge air to the top
of the pit. This is a minimum requirement.
Multiple Units
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 four feet.
Decorative Fences
Fences must have 50 percent free area, with a one-foot undercut,
a minimum clearance equal to the width of the unit and must
not exceed the height of the unit. If these requirements are not
met, unit must be installed as indicated for units in pits.
Sound and Vibration
Units should be installed away from occupied spaces
to reduce the transmission of sound and vibration
to occupied spaces. Units should be mounted over
corridors, utility areas, rest rooms and other auxiliary areas
where high levels of sound are not an important factor.
Sound and structural consultants should be retained
for recommendations.
The refrigerant piping should be flexible enough to
prevent the transmission of noise and vibration from the
unit into the building. If the refrigerant lines are to be
suspended from the structure of the building, isolation
hangers should be used to prevent the transmission
of vibration.
Where piping passes through a wall, it is advisable to pack
fiberglass and sealing compound around the lines to minimize
vibration and retain flexibility in the lines. The unit needs to
be secured in its final location. Holes are provided in the base
runner for this purpose.
