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.

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.
