6. Check the mounting bolts on the unit,
compressor and fan motors. Tighten if
necessary.
7. Clean the defrost drains.
8. Inspect water-cooled condenser-receiver tank,
water lines and fittings for water leaks. When
water lines are disconnected, also check to be
sure that the water drains completely from the
condenser-receiver tank. Report defective
fittings and tanks that do not drain to a
technician.
9. Optional: Check water level in humidity
system tank. Add only demineralized or
distilled water to prevent plugging of the
atomizing nozzle.
10. Observe the unit for proper operation and
functions during Pre-load Operation.
11. Check to be sure the container ID that appears
in the Configuration menu is correct.
Functional Inspection
To properly perform a Full Pretrip Test on units
equipped with a MPC2000ID or MP-3000a
controller, the container must be empty with the
rear doors closed.
1. Start the unit (see “Starting the Unit and
Adjusting the Controller Setpoint” on page
3-5). A second sequence start of the required
loads occurs during the Pretrip test:
• Controller LED display turns On and then
Off.
• LED display briefly shows setpoint and
then displays the controlling (return) air
sensor temperature.
• Controller senses the incoming power
phase and selects the correct power phase
to unit components.
• Evaporator fan motors start.
2. If the controller calls for cooling, the
compressor motor starts and the liquid line
solenoid energizes (opens). If the unit starts in
Modulation Cool, compressor start-up can be
delayed up to 3 minutes while the KVQ valve
opens or closes to the required setting.
• On cooling, the condenser fan starts as
required when the unit is on air-cooled
condensing operation.
3. If the controller calls for heating, the electric
heaters are energized.
NOTE: If the compressor fails to start, turn
the On/Off switch OFF. Then repeat steps 1
through 3. If the unit still does not start, refer
to “Alarm Codes, Descriptions and
Corrective Actions” in the Controller chapter
of this manual. Be sure to wait up to 3
minutes for the compressor to start.
4. Adjust controller setpoint to the desired
temperature:
NOTE: The setpoint temperature can be set
between -29 C and +29 C (-20.2 F and +84.2
F) in either °F or °C using the °C/ °F key.
Just press and hold the F/C key (to display
the alternate temperature scale).
• Press SETPOINT key to display cursor
flashing in the “TEMP SETP” line
• Press F4 key to enter new setpoint. Enter
Arrow appears in the menu line and the
current setpoint disappears.
• Enter minus sign first by pressing EXIT
key. Then press numeric keys to enter new
setpoint.
• With correct setpoint in display, press and
hold F4 key until cursor stops flashing.
Controller places new set-point in
controller memory and shows new
setpoint in LCD display.
NOTE: New setpoint must be between -29 C
and +29 C (-20.2 F and +84. 2 F) or
controller will return to the previous setpoint
display.
CAUTION: Air or water spray jet pressure
should not be high enough to damage
(bend) coil fins.
