COLD AREA RECOMMENDATION
- Outdoor heat pump unit : install the unit at least 10 cm above ground level to facilitate drainage of defrost water and
prevent accumulation of ice. In effect, defrost water can cause accumulation of ice under the unit during subfreezing
outdoor temperatures.
- In areas with heavy snowfall, it is best to install the unit on wall supports.
- In some regions, it is necessary to heat the bottom of the condensate drainage pan and the condensate drainage
piping to avoid ice formation, and resulting ice build-up in the fan compartment (heater strip must be at least 25
W/m).
■ Wiring
Prepare the power source for exclusive with the air conditioner.
The supply voltage must comply with the rated voltage of the air conditioner: The plug socket shall be accessible after
installation.
Remark: All the wiring must be based on the wiring nameplate which shown on the model.
CAUTIONS
• Perform the wiring with suffi cient capacity. Installation places legally require a short circuit isolator to be attached
to prevent electrical shock.
• Do not extend the power cable code by cutting.
• Power voltage should be in the range of 90%~110% of rated voltage.
The plug of the air conditioner takes a grounding leg, so clients should use a grounding socket so that the air
•
conditioner can be grounded effi ciently.
If the power cord is damaged, replacement should be conducted by qualifi ed technician or a serviceman.
•
Remark per EMC Directive 89/336/EEC
NOTE
For to prevent fl icker impressions during the start of the compressor (technical process), following installation conditions do
apply.
1. The power connection for the air conditioner has to be done at the main power distribution.
The distribution has to be of a low impedance, normally the required impedance reaches at a 32 A fusing point.
2. No other equipment has to be connected with this power line.
3. For detailed installation acceptance, please refer to your contract with the power supplier if restrictions do apply
for products like washing machines, air conditioner or electrical ovens.
4. For power details of the air conditioner, refer to the rating plate of the product.
5. For any question contact your local dealer.
CAUTIONS
• Never modify the unit by removing any of the safety guards or by bypassing any of the safety interlock
switches.
• Connect the connecting cable correctly and connect the connecting cable to terminal as identifi ed with their
respective marks.
• Do not scratch the conductive core & inner insulator of power supply cables and do not deform or smash on the
surface of cables.
