INSPECTION – DAMAGE – SHORTAGE
The unit shipment should be checked on arrival to see
that all major pieces, boxes and crates are received.
Check each unit on the trailer or rail car when received,
before unloading, for any visible signs of damage. Re-
port any damage or signs of possible damage to the
transportation company immediately for their inspec-
tion. Johnson Controls is not be responsible for any

check contents against the packing list. Any material
shortage should be reported to Johnson Controls im-
mediately. (Refer to Shipping Damage Claims, Form
50.15-NM.)

CHILLER DATA PLATE

A unit data plate is mounted on the control center as-
sembly of each unit, giving unit model number; design
working pressure; water passes; refrigerant charge; se-
rial numbers; and motor power characteristics and con-
nection diagrams.
Additional information may be found on the motor data
plate. Include this information when contacting the fac-
tory on any problem relating to the motor.

LONG-TERM STORAGE

To protect the waterbox of pressure vessels from rust-
ing, the tube side (water side) is purged and charged
with nitrogen to a positive pressure of 5 psig to 7 psig.
Do not break the seal or remove closures until ready
for set up. Use the following procedure to relieve pres-
sure (see Figure 3 on page 10).
Failure to follow the following procedures
will cause severe personal injury or death
to operators themselves or people on-site.
It is the obligation and responsibility of
