-
Cut the box on the shorter side of the installed piping for better access to the self-tapping locking bolts.
-
Secure the installed piping with self-tapping bolts
Ø
4 x 22 mm (part of the mandatory accessories delivery
– box 2) against each other as shown in Fig. 15 – 4, at a distance of 20 mm from the edge of the unit, see
Fig. 16.
-
Tighten the self-tapping bolts with a reasonable force to prevent damage to the plastic tube and the
socket of the unit.
-
Orient the length-adjusted piping – assembly with a damper
before sliding it onto the socket of the unit:
o
The blue dot located on the tube body must be directed towards the blue dot on the body of the
unit (the damper must be positioned towards the unit),
o
Blue dots (on the tube and on the unit) must be also positioned in one axis to ensure the axial
alignment of the tube with the damper and unit.
-
Slide the assembly so oriented onto the top socket of the unit by rotating it back and forth while pushing
it down, into the groove.
-
After fitting the tube onto the top socket, check its perpendicularity to the back of the unit and the correct
orientation of the blue dots.
-
Seal the installed piping on the sockets around the perimeter and apply the MS polymer-based sealant to
form a corner joint across the entire socket thickness.
-
Secure the installed piping with self-tapping bolts
Ø
4 x 22 mm against each other as shown in Fig. 15 – 4,
at a distance of 20 mm from the edge of the unit, see Fig. 16.
3.2.6. Gluing Insulating Pads
-
For proper sealing of the piping and unit in relation to the opening in the wall (construction module),
apply a polyethylene insulating pad, which is included in the unit packaging, to the installation template.
-
Remove the adhesive foil from the pad's back side.
-
Attach the pad in line with the installation marks drawn on the installation template.
CHECK POINT
-
Before continuing work, check that the piping fits correctly:
o
piping without a damper (only a tube) is installed on the lower socket,
o
piping with a damper is installed on the upper socket:
the damper is positioned towards the unit,
blue dots (on the piping and on the unit) face each other and are axially aligned,
o
both the tubes are perpendicular in all the directions to the rear of the unit,
o
both the tubes are sealed with MS polymer-based sealant in socket grooves,
o
sealant is applied between the outer wall of the socket and the inner wall of the tube,
o
both the tubes are fitted with sealant to the sockets via a corner joint over the entire thickness of
the socket,
o
supply (with damper) and exhaust piping are secured with self-tapping bolts.
o
The insulation pads are glued to the installation template
-
IF ANY CHECK POINT IS NOT OBSERVED, FIX IT.
