1. PRECAUTIONS FOR SAFETY

1.1 Foreword

• This manual has been published to service the MovinCool Climate Pro 12. Please use this

service manual only when servicing the Climate Pro 12.

1.2 Definition of Terms

1.3 General Precautions

WARNING

• All electrical work should only be performed by qualified electrical technician. 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 dealer.

• Disconnect power supply from the unit before performing any service.

• Before replacing any refrigeration components, recover the refrigerant using standard

recovery procedures and equipment.

• When handling refrigerant, always wear proper eye protection and do not allow the

refrigerant to come in contact with your skin.

• Do not expose refrigerant to an open flame.

• The power supply for this unit should be a dedicated single outlet circuit with a UL

recognized short-circuit and ground-fault protective breaker to prevent electrical shock

from the unit.

• When brazing any tubing, always wear eye protection, and work only in a well ventilated

area.

• Be careful of any sharp edges when working on unit.

Describes precautions that should be observed in order to prevent injury to

the user during installation or unit operation.

Describes precautions that should be observed in order to prevent damage to

the unit or its components, which may occur during installation or unit

operation if sufficient care is not taken.

NOTE Provides additional information that facilitates installation or unit operation.

2.4 Basic Construction

• The Climate Pro 12 is compact in construction because the indoor and the outdoor heat

exchangers are enclosed in one unit. The interior is divided into three sections. The upper front

face is equipped with the indoor heat exchanger, and the lower front face contains the drain tank

and condensate pump (optional accessory). The rear section contains the outdoor heat

exchanger, the compressor and the control box.

2.5 Air Flow

• In Cool Mode, air drawn from the outdoor air inlet passes through the heat rejection coil

(condenser) and discharges hot air through the exhaust hot air outlet. Air take in from the indoor

air inlet passes through the heat absorption coil (evaporator) and discharges the cool air through

the cool air outlet.

• In Heat Mode, the refrigeration in the unit operates in reverse cycle and the heat rejection coil

(condenser) becomes the heat absorption coil (evaporator). Air drawn from the outdoor air inlet

passes through this heat absorption coil and discharges cool air through the exhaust cool air

outlet. Air taken in from the indoor air inlet passes through the heat rejection coil and discharges

hot air through the hot air outlet.

2.6 Compressor and Fans

• The compressor is hermetically sealed. The indoor fan is a centrifugal type and operated by a

3-speed motor to draw air through the indoor air inlet. The outdoor fan is also a centrifugal type

and operated by a 1-speed motor to draw air through the outdoor air inlet.

2.7 Drain Tank

• A 5.0 gal (19 L) drain tank is supplied with the Climate Pro 12. The condensate (water) is

collected into the tank.

The drain switch activates and stops the operation when tank reaches the level of approximately

4.0 gal (15 L).
