Connecting The Pipes - Mitsubishi Electric VL-350CZPVU-L-E Installation Manual

4.4 Connecting the Pipes

4.4.1 Piping Ducts
WARNING
Install the ducts in the indoor side of the insulation layer/
airtight layer.
When installed on the outdoor side of the heat insulating
layer, the temperature of the heat-recovered air will drop and
condensation will form, which will cause the floor to get wet.
Secure duct piping with commercially available fixing
bands, aluminum tape, etc. to prevent piping from loose.
Install outdoor piping from the product so that it is tilted
at a downward pitch of at least 1/30 towards the outside.
Failure to heed this warning may cause rain penetration,
resulting in electric shock/fire or water damage to household
property.
Piping should be installed so that no load is applied to
the pipe guide.
Failure to heed this warning may cause damper mulfunction.
Note
- When discharging the air from a bathroom, use ducts made
of a material that does not allow water to leak.
- When using PVC ducts or metal ducts for the SA side
ducts, make sure to connect ducts having silencer before
the grill.
- The duct for exhaust from the bathroom and the pipe guide
should be sealed with caulking material.
- When using calking material, take care to prevent it from
oozing from the ducts. (Otherwise, it could cause aluminum
tape to peel off.)
- Before connecting the ducts, make sure that there are no
metal chips or other foreign matter (For example paper or
vinyl) inside the ducts or inside the product.
