14 - 2 KDDM24B50, KDDM24B100: Silencer

Applications and features

• The silencer effectively reduces the noise of the HRV units.
• Air flow rate should be lower than 600 m

/ h for the model

KDDM24B50 and lower than 1000 m

/ h for the model

KDDM24B100.

Caution

The silencer cannot be used on different model. Confirm the

model before installation.

Installation procedure

1. Remove the flange from the

silencer.

2. Remove the duct coupling of

the air inlet provided on the
body of HRV units.

3. Use the provided screws and

install the flange on the HRV
units.

4. Install the silencer on the

flange. Then, install the duct
coupling.

5. Insert the duct into the duct

coupling and wind round the
commercially available
aluminum tape, etc. to prevent
the air leakage.
