SPECIFIC WARNING AND CAUTION STATEMENTS - - Continued
WARNING
Make sure power to the unit is OFF and
power plug disconnected before removing
capacitor(s).
WARNING
With power OFF discharge the capacitor
before disconnecting the circuit wiring.
WARNING
The unit power plug must be disconnected
to remove power from circuit breaker CB1
CAUTION
Do not remove wire harnesses from controller
unless you are grounded to the unit frame with a
static safe wrist strap.
CAUTION
Unplug all controller wire harness connectors
before performing arc welding on any part of the
container.
CAUTION
Pre-trip inspection should not be performed
with critical temperature cargoes in the contain-
er.
CAUTION
When Pre-Trip key is pressed, dehumidification
and bulb mode will be deactivated. At the
completion of Pre-Trip activity, dehumidification
and bulb mode must be reactivated.
CAUTION
When condenser water flow is below 11 lpm (3
gpm) or when water-cooled operation is not in
use, the CFS switch MUST be set to position "1"
or the unit will not operate properly.
T-305
When a failure occurs during automatic testing
the unit will suspend operation awaiting opera-
tor intervention.
When Pre--Trip test Auto 2 runs to completion
without being interrupted, the unit will terminate
pre-trip and display "Auto 2" "end." The unit will
suspend operation until the user depresses the
ENTER key!
The unit will remain in the full cooling mode as
long as the emergency bypass switch is in the
BYPASS position. If the cargo may be dam-
aged by low temperatures, the operator must
monitor container temperature and manually
cycle operation as required to maintain temper-
ature within required limits.
The unit will remain in the DEFROST mode as
long as the emergency defrost switch is in the
DEFROST position. To prevent cargo damage,
the operator must monitor container tempera-
ture and manually cycle operation as required
to maintain temperature within required limits.
To prevent trapping liquid refrigerant in the
manifold gauge set be sure set is brought to
suction pressure before disconnecting.
Removing the compressor motor press-fit sta-
tor in the field is not recommended. The rotor
and stator are a matched pair and should not be
separated.
