When Fan speed is set at Auto in cooling mode, it will be automatically reduced as room temp. is approaching temp. setting. 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.
12
Energy saving
Keep proper room temp.
Too cold or too warm is no good to your health, and power consumption will be increased as well.
Air filter should be periodically cleaned
If air filter is clogged:
It will cause poor cooling and heating efficiency, higher power consumption and even problem may occur. In cooling operation, water will flow out.

To protect compressor at start, please connect external power supply to the unit 12 hrs prior to starting. Also please keep the power supply switch ON during the whole season.
15
Trouble shooting
Followings are not problems
Sound of water flowings are not problems.
Sound of cracking is heard.
Smells are generated.
During operation, white fog or steam comes out of indoor unit.
In cooling operation, unit switches to fan operation.
Unit will not restart after stop. Won't start?
During unit start and operation or at stop, a swishing or gurgling noise may be heard. This noise is generated by refrigerant flowing in the system.
During unit operation, a cracking noise may be heard. This noise is generated by the casing expanding or shrinking because of temperatuer changes.
This is because the system circulates smells from the interior air such as the smell of cigarettes or the painting on the unit.
When unit is running at places like restaurant where dense edible oil fumeis always exist, this will happen.
To prevent frost from accumulating on indoor heat exchanger, unit will switch to fan operation for a while then resume cooling operation.
Though ON/OFF button is set to ON, unit won't resume cooling,dry or heating operation in 3 min after it is stopped, this is because of 3­min-delay protection circuit.
No outlet air or fan speed can't be changed in dry mode.
In heating operation, water or steam are blown out of indoor unit.
In heating operation, indoor fan won't stop even if unit is stopped.
Please wait 3 minutes
Unit will reduce fan speed repeatedly and automatically if room temp. is too low in dry operation.
This occurs when frost accumulated on the outdoor unit is removed. (during defrosting operation)
After unit stops, indoor fan will go on running until indoor unit cools down.
