Moving and lifting
Avoid bumping and/or jolting during loading/unloading unit
from the truck and moving it. Do not push or pull the unit from
any part other than the basis. Secure the unit inside the truck
to prevent it from moving and causing damages. Do not allow
any part of the unit to fall during transportation or
loading/unloading.
Use extreme caution when handling the unit to prevent
damage to the control or the refrigerant piping. The unit must
be lifted by inserting a hook in each corner, where there are
holes for lifting (see fig. 3). Spacer bars must be used along
the line connecting the lifting holes to prevent damage to the
electric panel and motor terminal box. During the lifting phase
to verify that the ropes and / or the lifting chains do not touch
the electrical panel and / or piping. If moving the machine, you
had the sleds or skates, push only on the basis of the machine
without touching the pipes of copper, steel, compressors and /
or the electrical panel.
Both the lifting ropes and the spacing bars must be
strong enough to support the unit safely. Please check
the unit's weight on the unit nameplate.
