1.

Remove the control box lid.  Connect the remote controller 
and power supply (single-phase, 50 Hz 220-240 V or sin-
gle-phase, 60Hz 220V) respectively to the terminal block 
and securely connect the earth also (as shown in the figure 
below).

CAUTION

Securely clamp the cables with the clamps (9)(10) offered 

as accessories as shown in Fig. 17 so that tension will not 

be applied on the cable connection areas.

2.

Confirm that the control box lid is closed before turning on 
the power.

3.

Remove the inspection lid.

4.

Gradually pour approximately 1L of water from the inspec-
tion window into the drain pan to check drainage.

CAUTION

Be sure to prevent an external force from being exerted on 

the float switch. 

(This may cause breakage.)

5.

Attach the inspection lid.

6.

Perform the following operation using the remote controller, 
and check drainage.

Select the inspection/test operation button “

” using 

the remote controller.  The unit will engage the test oper-
ation. Press the operation selector button “

”, and 

select FAN OPERATION “

”.

Press the ON/OFF button “

”.  (The indoor fan and 

drain pump will operate.)

CAUTION

The fan will turn also at the same time.  Take due care.

Do not touch the drain pump to prevent electric shock.

7.

Make sure to use the remote controller in finishing the oper-
ation.

8. INSTALLING THE DUCT

Connect the duct supplied in the field.

Air inlet side

Attach the duct and intake-side flange (field supply).

Connect the flange to the main unit with accessory screws 
(7).

Wrap the intake-side flange and duct connection area with 
aluminum tape or something similar to prevent air escaping.

CAUTION

When attaching a duct to the intake side, be sure to attach an air 
filter inside the air passage on the intake side.  (Use an air filter 
whose dust collecting efficiency is at least 50% in a gravimetric 
technique.)
The included filter is not used when the intake duct is attached.

Air outlet side

Connect the duct according to the air inside of the outlet-side 
flange.

Wrap the outlet-side flange and the duct connection area 
with aluminum tape or something similar to prevent air 
escaping.

CAUTION

Be sure to insulate the duct to prevent condensation from 
forming. (Material: glass wool or polyethylene foam, 25 mm 
thick)

Use electric insulation between the duct and the wall when 
using metal ducts to pass metal laths of the net or fence 
shape or metal plating into wooden buildings.

Be sure to explain about the way of maintaining and cleaning 
local procurements (air filter, grille (both air outlet and suction 
grille), etc.) to your customer.
