SECTION 3 - RIGGING, HANDLING AND STORAGE

MOVING THE CHILLER

Prior to moving the unit, ensure that the installation
site is suitable for installing the unit and is easily
capable of supporting the weight of the unit and all as-
sociated services. Care should be taken to avoid dam-
aging the condenser cooling fins when moving the unit.
The unit must only be lifted by the base
frame using all lift points provided. Never
move the unit on rollers, or lift the unit
using a forklift truck.

UNIT REMOVAL FROM SHIPPING CONTAINER

1. Place a clevis pin into the holes provided at the
end of each base rail on the unit. Attach chains or
nylon straps through the clevis pins and hook onto
a suitable lift truck for pulling the unit out of the
container.
2. Slowly place tension on the chains or straps until
the unit begins to move and then slowly pull the
unit from the container. Be sure to pull straight so
the sides do not scrape the container.
3. Place a lifting fixture on the forks of the lift truck
and reattach the chain or strap. Slightly lift the
front of the unit to remove some weight from the
floor of the container. Continue pulling the unit
with an operator on each side to guide the lift
truck operator.
4. Pull the unit until the lifting locations are outside
of the container. Place 4 X 4 blocks of wood under
the base rails of the unit. Gently rest the unit on
the blocks and remove the chains and lift truck.
5. Once the unit is completely removed from the
container, follow the professional written rigging
plan to lift the unit.

LIFTING USING SHACKLES

The shackles should be inserted into the respective
holes in the base frame and secured from the inside.
Use spreader bars to avoid lifting chains hitting the
chiller. Various methods of spreader bar arrangements
may be used, keeping in mind the intent is to keep
the unit stable and to keep the chains from hitting the
chiller and causing damage. Never lift the chiller using
a forklift or by hooking to the top rails. Use only the
lifting holes provided. Lifting Instructions are placed
on a label on the chiller and on the shipping bag.

LIFTING USING LUGS

Units are provided with lifting holes in the base frame
which accept the accessory lifting lug set as shown
in the figure below. The lugs (RH and LH) should be
inserted into the respective holes in the base frame and
turned so that the spring loaded pin engages into the
hole and the flanges on the lug lock behind the hole.
The lugs should be attached to the cables/chains using
shackles or safety hooks.

Rigging and lifting should only be done by
a professional rigger in accordance with a
written rigging and lifting plan. The most
appropriate rigging and lifting method
will depend on job specific factors, such as
the rigging equipment available and site
needs. Therefore, a professional rigger
must determine the rigging and lifting
method to be used, and it is beyond the
scope of this manual to specify rigging
and lifting details.
