MOVING AND PLACING THE UNIT
MOVING THE UNIT
The McQUAY SEASONPAK water chiller is mounted
on heavy wooden skids to protect the unit from ac-
cidental damage and to permit easy handling and mov-
ing.
It is recommended that all moving and handling be
performed with the skids under the unit when possible
and that the skids not be removed until the unit is in
the final location.
When moving the unit, dollies or simple rollers can
be used under the skids, or dollies alone can be used
under ends of the frame. Do not use pipe rollers under
the unit if the skids have been removed.
T h e 4 ”
channel base is arranged on the skid so
that the fork of a standard fork lift truck can be slid
easily under (See Figure 1). The forks of the fork lift
truck must be across both the front and rear channels
before lifting.Never put the weight of the unit against
the condensers.
In moving, always apply pressure to the base on
skids only and not to the piping or shells. A long bar
helps move the unit easily. Avoid dropping the unit at
the end of the roll.
If the unit must be hoisted, it is necessary to lift
from the skid or from the base as indicated in Figure
2, Page 3. A spreader bar must be used to protect the
control cabinet and other areas of the chiller.
Do not attach slings to piping or equipment. Move
unit in the upright horizontal position at all times.
Let unit down gently when iowering from the trucks or
rollers.
