SECTION 3 - RIGGING, HANDLING, AND STORAGE

Inspection

Remove any transit packing and inspect the unit to
ensure that all components have been delivered and
that no damage has occurred during transit. If any
damage is evident, it should be noted on the carrier's
freight bill and a claim entered in accordance with the
instructions given on the advice note.
\Major damage must be reported immediately to your
local Johnson Controls representative.

Moving the chiller

Before 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
associated services.
The unit must only be lifted by the base
frame at the points provided. Never move
the unit on rollers, or lift the unit using a
forklift truck.
Care must be taken to avoid damaging the condenser
cooling fins when moving the unit.

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. Attach lifting rigging from the crane and slowly
complete the removal from the container then lift
up and away.

Lifting using lugs

Units are provided with lifting holes in the base
frame which accept the accessory lifting lug set as
shown in Figure 4. 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.

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 arrange-
ments 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 hook-
ing to the top rails. Use only the lifting holes pro-
vided.
• Lifting Instructions are placed on a label on the
chiller and on the shipping bag.
