SECTION 3 – HANDLING AND STORAGE
DELIVERY AND STORAGE
To ensure consistent quality and maximum reliability,
all units are tested and inspected before leaving the
factory. Units are shipped completely assembled and
containing refrigerant under pressure. Units are shipped
without export crating unless crating has been specified
on the Sales Order.
If the unit is to be put into storage, prior to installation,
the following precautions should be observed:
• The chiller must be “blocked” so that the base is
not permitted to sag or bow.
• Ensure that all openings, such as water connec-
tions, are securely capped.
• Do not store where exposed to ambient air tem-
peratures exceeding 110 °F (43 °C).
• The condensers should be covered to protect
the fins from potential damage and corrosion,
particularly where building work is in progress.
• The unit should be stored in a location where
there is minimal activity in order to limit the risk
of accidental physical damage.
• To prevent inadvertent operation of the pres-
sure relief devices the unit must not be steam
cleaned.
• It is recommended that the unit is periodically
inspected during 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
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 associated
services.
The units are designed to be lifted using cables. A
spreader bar or frame should be used in order to prevent
damage to the unit from the lifting chains.
Units are provided with lifting eyes in the sides of the
base frame, which can be attached to directly using
shackles or safety hooks.
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 should be taken to avoid damaging the condenser
cooling fins when moving the unit.
Lifting Weights
For details of weights and weight distribution, refer to
the data shipped in the chiller information packet and
unit nameplate.
The unit should be lifted by inserting
hooks through the holes provided in
unit base rails. Spreader bars should
be used to avoid crushing the unit
frame rails with the lifting chains (See
below).
