PRECAUTION
About fresh air intake kit
The Fresh Air Intake Kit can be installed onto cassette type air conditioners.
The volume of ventilated air provided by the Fresh Air Intake it
regulations in some countries.
On such occasions we ask that this kit be used along with Energy recovery ventilators.
When intaking outside air please ensure correct air-conditioning design based on air conditioning
load calculations.
As outside air is not being processed, an increase in outside air load can affect air conditioning.

Installation location

Area that generate substances that adversely affect the equipment, such as sulfuric
gas,chlorine gas,add,or alkali will cause the copper pipes and brazed joints to corrode, which
can cause refrigerant leakage.
Area with high salt content,such as at the seaside. It will deteriorate metal parts, causing the
parts to fall or the unit to leak water.
e certain to use e ectric da pers and shutters to a oid infi tration o co d air wind and og
during shutdown in areas with cold climates, strong winds, or where fogs are common.
Please ensure the product is installed a distance of at least three times the duct diameter away
from exterior wall air inlets, or air exhausts for the prevention of short circuits.
Temperature conditions
Condensation may form on the product when outside air temperature is low, and the temperature
and humidity surrounding the product are high. Don't intake the air of below 0° C into the Fresh air
intake kit.
The upper Iimit of the product's temperature range should respond to the outdoor temperature
range.
About duct fan
When installing the duct fan, connect the drive relay (
unit.
Please ensure the intake air volume is below 10% of the product's air volume HI. When
the intaken air volume becomes too large there the operating noise may increase and room
temperature detection may be affected.
About the duct connection
Procure a duct with interna dia eter that fits the e terna dia eter o the duct ange.
P ease note that regu ations o so e countries
the duct penetrates a fire retarding di ision or other fire proofing

regulatory requirement of some countries.
When using metallic ducts please ensure metals (i.e., metal lath, wire lath, stainless sheeting) are
e ectrica insu ated.
Please ensure to thermally insulate connected ducts to prevent condensation.
Please make certain that netting or other measures are installed in parts exposed to the outside
air to pre ent infi tration o s a ani a s such as birds and insects.
