1. PRECAUTIONS FOR SAFETY

1.1 Foreword

• This manual has been published to service the MovinCool 15SF.

Please use this service manual only when servicing the 15SF.

• Please forward these instructions to subsequent owners of your MovinCool 15SF.

• Refer to the 15SF spare parts catalogue for spare parts ordering information.

1.2 Definition of Terms

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

NOTE Provides additional information that facilitates installation or unit operation.

WARNING

CAUTION

Operation Section

1.3 General Precautions

WARNING

• All electrical work 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.

• This air conditioner uses R-410A refrigerant under high pressure. It is both dangerous

and illegal to tamper with the sealed refrigerant system without appropriate licensing and

training. Deliberate release of refrigerant is illegal in Australia, New Zealand and other

regions.

• Refrigerant recovery and charging equipment must be specifically rated for use with R-

410A.

• Observe Refrigerant Handling Code of Practice and all other applicable regulatory

requirements.

• 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 short-circuit

protection and residual current protective device to prevent electrical shock from the unit.

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

area.

• Disconnect power before servicing this unit.

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