Installation of HRV
I
Install the anchor bolt (M10 to 12) in advance.
Pass the metal suspension bracket through the anchor bolt and
secure the anchor bolt with washer and nut.
(Before installation, check for foreign objects such as vinyl and
paper remaining inside the fan housing.)
I
The metal suspension bracket is fitted on top of the standard
unit.
If the anchor bolt is long, install it on the bottom of the unit.
(Be sure to screw in the removed mounting screw on top to
prevent air leakage.)
Install the duct caution name plate property on the indoor side
(SA·RA) and outdoor side (EA·OA).
NOTE Remove the two fixing metals for transportation if it

Duct connection
Do not connect the ducts as follows
Extreme bend
Do not bend the duct over 90°
Reduce the diameter of the duct to be connected.
Do not reduce the duct diameter halfway.
1 The minimal radius of bends for flexible ducts are as follows:
300 mm duct: 200 mm diameter
375 mm duct: 250 mm diameter
2 To prevent air leakage, wind aluminium tape round the section
after the duct connecting flange and the duct are connected.
3 Install the opening of the indoor air intake as far as from the
opening of the exhaust suction.
4 Use the duct applicable to the model of unit used (Refer to the
outline drawing.)
5 Install the two outdoor ducts with down slope (slope of 1/50 or
more) to prevent entry of rain water. Also, provide insulation for
both ducts to prevent dew formation. (Material: Glass wool of
25 mm thick)
6 If the level of temperature and humidity inside the ceiling is
always high, install a ventilation equipment inside the ceiling.
7 Insulate the duct and the wall electrically when a metal duct is to
be penetrated through the metal lattice and wire lattice or metal
lining of a wooden structure wall.
