Sound Vibration; Walls Or Obstructions; Multiple Units; Units In Pits - Daikin IOM 1062 Installation, Operation And Maintanance Manual

Sound Vibration

Install units away from occupied spaces, utility areas, corridors and auxiliary spaces to
reduce the transmission of sound and vibration to occupied spaces. The fluid piping should
be flexible enough to prevent the transmission of noise and vibration from the unit into the
building. If the fluid lines are to be suspended from the structure of the building, use
isolation hangers to prevent the transmission of vibration. Where piping passes through a
wall, pack fiberglass and sealing compound around the lines to minimize vibration and
retain flexibility. The unit must be secured in its final location. Holes are provided in the
base runner for this purpose
Vertical airflow type units should be located no closer than the width of the unit from a wall
or other obstruction. It two or more units are to be positioned in the same area, a similar
distance should be maintained between adjacent units. Sufficient free area should be left
around and below unit to avoid air restriction to coil.

Walls or Obstructions

Locate the unit to ensure that air can
circulate freely and not be recirculated. For
proper air flow and access, all sides of the
unit must be at least the distance shown away
from any wall or obstruction. Increase this
distance whenever possible. Be sure enough
room is left for maintenance through access
doors and panels. Overhead obstructions are
not permitted. When enclosed by three walls
the unit must be installed as indicated for
units in a pit.

Multiple Units

For units placed side by side, the minimum
distance between units is as shown. If units
are placed end to end, the minimum distance
between units is 4 feet.

Units in Pits

The top of the unit should not be more than
two feet below the top of the pit, and side
minimum distance on all four sides as
shown.

Decorative Fences

Fences must have 50% free area, with 1 foot
undercut, at least the width of condenser
minimum clearance, and must not be higher
than the top of unit. If these requirements
are not met, unit must be installed as
indicated for "Units in Pits".
