Preface - Carrier FDT21 Operation & Installation Manual

Checking Product Received
Upon receiving your unit, please inspect for damage. Claims for damage should be reported
immediately to the transportation company. Check that the unit is correct against your order. In
the event an incorrect unit is delivered, it must be returned to the supplier and must NOT be installed.
The manufacturer assumes no responsibility for installation of incorrectly delivered units.
Before Installation
Read all instructions carefully prior to installation. Please ensure every step described in this manual is
understood and taken into account before starting installation.
Proper installation will help ensure trouble free operation. Improper installation may result in problems
such as noisy operation, compressor damage, improper operation or dangerous conditions that could
result in injury or property damage and this could also void the warranty.
Overcurrent Protection
Overcurrent protection which is less than the recommendation could result in unnecessary fuse failure
and chargeable service call. The manufacturer bears no responsibility for damage caused to the
equipment as a result of deviation from the recommended rating.
Refrigerant tubing
Keep refrigerant tubing clean and dry prior to and during installation to avoid equipment damage.
Homeowner
The user should retain this manual for future reference. To ensure the warranty is continued
and valid, the unit shall be required to be serviced as per section on "REGULAR/ PREVENTIVE
MAINTENANCE". Attention should be given to the air inlet side of the outdoor coil to ensure that
leaves, grass and etc are not being drawn into the unit. Restriction to air flow across the coil will
reduce the system capacity or result in high operating pressures and excessive operating cost. There
must be air filters installed in the system at some point upstream to the indoor unit. Air filters should
be inspected at least once a month.
Your air conditioner is designed and built with reliable components to provide years of trouble free
dependable service. However, it will require regular maintenance either by yourself (end user)
or a licensed technician to keep your warranty on the unit valid.
Important
The Australian greenhouse office has issued various regulations on the use and disposal of refrigerants
in this unit. Failure to follow these regulations may harm the environment and could lead to the
imposition of substantial fines.
Only qualified and licensed technician should perform work on this unit, otherwise the warranty on the unit
will be void.
