Operation hints

Unit operation

Protection devices inside the unit will activate to stop unit operation, when ambient temp. is extremely low or high.

When unit is running under high humidity in cooling or dehumidifying mode, conden- sate might appear at outlet grill.

3-min delay protection

Unit will not restart until 3 min have elapsed for the protection of the unit.

Fan speed changes

When Fan speed is set at Auto in cooling mode, it will be automatically reduced as room temp. is approaching temp. setting.

In heating mode. when room temp. reaches temp. setting, compressor will stop and fan speed LOW or stop.

In dry mode, fan speed will change automatically.

Cold draft prevention

In heating mode, indoor fan will not run for the first 2-5 min. due to cold draft prevention.

Defrosting

When frost accumulates on heat exchanger in heating mode, unit will start defrosting automatically.

During defrosting, both indoor and outdoor fan stop. After defrosting, unit resumes running.

Use objectively

Heat pump works by means of absorbing outside heat to warm room air, so outdoor temp. degree will affect unit's heating efficiency.
