Installing The Duct - Sanyo ECO R410A Installation Instructions Manual

3-11. 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 10 - Ø 1/8" (Hole) screws.
● 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 outside 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, 1 in. 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.
