INSPECTION – DAMAGE – SHORTAGE
The unit shipment should be checked on arrival to see
that all major pieces, boxes and crates are received.
Each unit should be checked on the trailer or rail car
when received, before unloading, for any visible signs
of damage. Any damage or signs of possible damage
must be reported to the transportation company imme-
diately for their inspection. Johnson Controls will not
be responsible for any damage in shipment, at job site,
or loss of parts. (Refer to Shipping Damage Claims,
Form 50.15-NM.)
When received at the job site all containers should be
opened and contents checked against the packing list.
Any material shortage should be reported to Johnson
Controls immediately. (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. This information should be included when con-
tacting the factory 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) has been 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. Relieve pressure as per the following proce-
dure (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
