GENERAL WARNINGS & CAUTIONS

• All electrical work, if necessary, should only be performed by
qualified electrical personnel. Repair to electrical components by
non-certified technicians may result in personal injury and/or
damage to the unit. All electrical components replaced must be
genuine MovinCool parts, purchased from an authorized reseller.

• The proper electrical outlet for MovinCool units must be equipped
with a UL approved ground-fault breaker to prevent electrical shock
from the unit.

• Because of potential safety hazards under a certain condition, we
strongly recommend against the use of an extension cord. However,
if you still elect to use an extension cord, it is absolutely necessary
that it will be a UL listed, 3-wire grounding type appliance extension
cord, having a 3-blade grounding plug and a 3-slot receptacle that
will plug into the appliance. The marked rating of the extension cord
should be 115 V, 15 A or equivalent.

• The Office Pro 18 is equipped with a ten (10) foot (3 meter) power
cord. If replacement, fixed location (hard wired) or power cord
lengthening (extension cord) cords are required, contact your
reseller or a qualified electrician for approved replacement meth­ods.

• Never fold or place heavy objects on the power cord. This could
result in damage to the power cord causing electrical shock or fire.

• Do not place water or any other liquid on the unit. This can cause
damage to the unit and increase the risk of electrical shock.

• Do not sit or stand on the unit.

12

OPERATION (cont.)

Operating Modes

The Office Pro 18 operates in two modes, Fan Only and COOL. When in
Fan Only mode, the unit circulates the surrounding air. When in COOL
mode, the compressor is operational and cool air is circulated.

• COOL Mode

The unit will operate in Fan Only mode for approximately 120
seconds before the compressor engages. (Time delay setting is 120
± 15 seconds.)

•Temperature Control

The room temperature thermistor allows the unit to switch automati­cally between COOL and Fan Only modes. This is dependent upon
inlet air temperature versus SET POINT temperature.

• Fan Mode Control DIP Switch

The Fan Mode Control DIP Switch determines whether the FAN will
continue to operate or stop when the compressor cycles off. (SET
POINT temperature equals inlet air or room temperature.) The unit
has been preset at the factory for continuous fan operation.

•Temperature Scale Display DIP Switch

The Temperature Scale Display DIP Switch changes the
temperature(s) that are displayed to either °C or °F. The unit has
been preset from the factory to display the temperature(s) in °F.

NOTE: If you wish to change the fan mode operation
(COOLOPERATE to COOLSTOP), and/or the Temperature Scale
Display (°F to °C), contact your MovinCool reseller.

OPERATION (cont.)

Drain Pump Kit (Optional)

A drain pump kit (CPK-3) is available to allow continuous operation and
to eliminate the need for a drain
tank.

• When the water collects to level
(A) in the pump reservoir, the
drain pump begins to operate
and discharges the water.

NOTE: The compressor will not operate while the drain pump is
discharging water.

• When the water level drops below level (B), the drain pump stops,
and the compressor will restart.
