1. FEATURES

● High static pressure

• Recommended external static pressure is 200Pa (Max. 300Pa).

● Functional LCD wired remote controller (See the next page for details.)

• Weekly timer
Air conditioner ON/OFF can be set for one whole week, including 2 times a day.

• Auto restart function in case of power failure

• Zone control
Only preset air conditioners can be stopped by pressing the ZONE CONTROL button.

● Energy saving operation

• ENERGY SAVE mode uses a computer program to economically control unit operation by
raising the set temperature slightly in the cooling mode and lowering the set temperature in the
heating mode.

● Pipe length up to 50m with height differential up to 30m

● Easy maintenance

• Fan motor maintenance
Fan motor maintenance can be perfor med from top, bottom, right side, or left side. (Fig. 1)
Fan motor hooks to the panel and is safe and easy to mount and dismount. (Fig. 2)

● Remote sensor unit (Option)

• Temperature sensor unit to be placed in the room

Do not purge the air with refrigerants but use a vacuum
pump to vacuum the installation! There is no extra re­frigerant in the outdoor unit for air purging!

Use a vacuum pump for R407C exclusively. Using the
same vacuum pump for different refrigerant ma y dam­age the vacuum pump or the unit.

When moving and installing the air conditioner, do not
mix gas other than the specified refrigerant R407C
inside the refrigerant circuit.

When charging the refrigerant R407C, alwa ys use an
electronic balance for refrigerant charging (to measure
the refrigerant by weight).

When charging the refrigerant,
take into account the slight change
in the composition of the gas and
liquid phases, and always charge
from the liquid phase side whose
composition is stable.

Add refrigerant from the charging valve after the
completion of the work.

Use a brand-new refrigerant piping when replacing the
air conditioner using the refrigerant except R407C and
R410A.

The installed drain pipe should have a downward gradient of 1/50
to 1/100. Make sure that the drain pipe is installed without rises.
Use general hard polyvinylchloride pipe (VP25) and connect
it with adhesive (polyvinylchloride) so that there is no leak­age. Do not perform air bleeding.
