might appear at outlet grill.
3-min delay protection
Fan speed changes

Operation hints
Cold draft prevention
Use objectively
efrosting
In heating mode, indoor fan will not run for the first 2 5 min. due to cold draft prevention.
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.
Heat pump works by means of absorbing outside heat to warm room air, so outdoor
temp. degree will affect unit's heating efficiency.

5
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.
Use Timer effectively

a comfortable room temp.when
you wake up or come home from

There might be certain power consumption even
if unit is stopped.
Clean air filter and indoor unit, cover outdoor
unit after cleaning.
Check if there are obstacles at inlet and outlet of indoor and outdoor unit,
whick will reduce unit efficiency.
Don't fail to attach air filter after making sure it
is cleaned.

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?
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.
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 3
min delay protection circuit.
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.
Please wait 3 minutes
