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
w ith accessory scre w s
(in 20 or 24 positions).
• Wrap the intake-side flange and duct connection area w ith
aluminum tape or something similar to prevent air escap-
ing.
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
w hose dust collecting efficiency is at least 50% in a
gravimetric techni q ue.)
The included filter is not used w hen 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
w ith aluminum tape or something similar to prevent air
escaping.
CAUTION
• Be sure to insulate the duct to prevent condensation from
forming. (Material: glass w ool or polyethylene foam, 1 in.
thick)
• Use electric insulation bet w een the duct and the w all w hen
using metal ducts to pass metal laths of the net or fence
shape or metal plating into
w ooden buildings.
• Be sure to explain ho w to clean local procurementssuch as
air filters and grilles to your customer.
9. ELECTRIC WIRING WORK
9-1 GENERAL INSTRUCTIONS
• Shut off the po w er before doing any w ork.
• All field supplied parts and materials, electric w orks must
conform to local codes.
• Use copper w ire only.
• See also the Wirin g Dia g ram label attached to the control
box lid w hen laying electrical w iring.
• For details on hooking up the remote controller, refer to the
REMOTE CONTROLLER INSTALLATION MANUAL .
• All w iring must be performed by an authorized electrician.
• This system consists of multiple indoor units. Mark each
indoor unit as unit A, unit B , and so forth, and be sure the
CAUTION
• The electric w iring w ork shall be performed by q ualified
electricians.
• If w orkers not having the electrician q ualification have per-
formed the electric w iring w ork, the steps 3 to 7 shall be
performed after the TEST RUN .
1. Remove the lid of the control box. Connect the remote
controller and po w er supply (single-phase, 60Hz 208-
230 V ) respectively to the terminal block and securely
connect the ground also as sho w n in the figure belo w .
Securely clamp the cables w ith the accessory clamps
(9)(10) as sho w n in Fig. 14 so that tension w ill not be
applied on the cable connection areas.
2. Confirm that the lid of the control box is closed before
turning on the po w er.
3. Remove the inspection lid.
4. Gradually pour approximately 2
q uarts of w ater from
the w ater inlet into the drain pan to check drainage.
CAUTION
Be sure to prevent external force from being exerted on
the float s
w itch or breakage can occur. Attach the
inspection lid
5. Perform the follo w ing operation using the remote con-
troller, and check drainage.
• Select the inspection/test operation button “ ”
using the remote controller. The unit w ill engage the
test operation. Press the operation selector button
“ ”, and select FA N OPERATIO N “ ”.
• Press the O N /OFF button “ ”. The indoor fan and
drain pump w ill operate.
CAUTION
Be cautious of the fan turning simultaneously. Do not
touch the drain pump to prevent electric shock.
6. Make sure to use the remote controller in finishing the
operation.
