STEP 3: SEALING ON THE BACK OF THE EVAPORATOR
Preparing the sheet metal for the backside
1. Glue the 24 cm long stripe of the sealing tape centered
at the inside of the straight sheet metal as shown. The
overlapping shall be between 2 and 5 mm.
Caution!
Do not touch the sheet metal parts without wearing
work gloves as the acidic hand sweat etches the
fingerprints even into stainless steel surfaces and to
avoid injuries.
Before gluing check the correct orientation of the part
and the positioning of the sealing tape. The gluing must
be done carefully to ensure that the gaps are closed,
and no water can splash through.
Assembling of the sheet metal for the back side
1. Assemble the sheet metal at the back of the evaporator
at the inside of the plastic water basin as shown.
2. To do this insert the metal sheet first at the left side
between the plastic wall and the metal bracket of the
evaporator (1.)
3. To check: Correct orientation of the part is when the 2
short bends left and right of the sheet metal are at the
bottom and point in the direction of the evaporator.
4. Move the sheet metal down (2.) and at the same time
move it to the right (3.) until it fits in the yellow marked
area.
5. Glue the protruding ends of the butyl round cord to the
sheet metal as shown to close the gap in this area.
Caution!
Before gluing check the correct orientation of the part
and the positioning of the sealing tape. The gluing must
be done carefully to ensure that the gaps are closed,
and no water can splash through.
Sealing in the middle with the sealing tape
1. Press the sheet metal to the plastic wall, fold down the
sealing tape and glue it to the plastic and EPP part as
shown.

Sealing left and right with 2 other sealing tapes
1. Use the 2 pcs. of 5,5cm long sealing tapes to seal the
gap between the sheet metal and the plastic wall at the
left and the right in the same way as shown.
STEP 4: SEALING IN FRONT OF THE EVAPORATOR
Preparing the sheet metal
1. Glue 2 pcs. of the 11cm long stripes of the sealing tape
at the other sheet metal part as shown. The
overlapping shall be between 2 and 5mm and the
sealing tape shall be positioned at the inside edges of
the sheet metal (blue arrow).
Assembling of the front-sheet metal
1. Assemble the sheet metal in front of the evaporator at
the inside of the plastic water basin as shown.
2. To do this insert the sheet metal first at the right side
between the plastic wall and the metal bracket of the
evaporator (1.)
3. Move the sheet metal down (2.) and at the same time
move it to the left (3.) until it fits in the yellow marked
area.
Caution!
Before gluing check the correct orientation of the part
(correct position of the cut out marked with the yellow
arrow) and the positioning of the sealing tape. The
gluing must be done carefully to ensure that the gaps
are closed, and no water can splash through.

Sealing with the 2 protruding ends left and right
1. Glue the protruding ends of the butyl round cord to the
sides of the sheet metal as shown to close the gap in
this area between the sheet metal and the plastic water
basin.
Caution!
Before gluing check the correct orientation of the part
and the positioning of the sealing tape. The gluing must
be done carefully to ensure that the gaps are closed,
and no water can splash through.
Sealing with the 2 pre-glued sealing tapes left and right
1. Press the sheet metal to the plastic wall, fold down the
sealing tape and glue it to the plastic and EPP part as
shown (at the left and the right side).
Caution!
Before gluing check the correct orientation of the part
and the positioning of the sealing tape. The gluing must
be done carefully to ensure that the gaps are closed,
and no water can splash through.
Sealing in the middle at the top
1. Glue one of the 13 cm long stripes of the sealing tape
centered at the front of the sheet metal as shown.
Position it at the edge of the bending (yellow arrow).
2. Press the sheet metal down to the plastic part, fold
down the sealing tape and glue it to the plastic and EPP
part as shown.
Caution!
Before gluing check the correct positioning of the
sealing tape. The gluing must be done carefully to
ensure that the gaps are closed, and no water can
splash through.

Sealing in the middle at the bottom
1. Glue the other pcs. of the 13 cm long stripes of the
sealing tape at the EPP part as shown. The overlapping
shall be between 5 and 8 mm and the sealing tape shall
be positioned centered.
2. Fold the sealing tape down and glue it to the EPP part
and the other sealing tape that was glued before.
Caution!
Before gluing check the correct positioning of the
sealing tape. The gluing must be done carefully to
ensure that the gaps are closed, and no water can
splash through.
Sealing of the side walls with the sealing tapes
1. Use 2 pcs. of 3cm long sealing tapes to seal at the sides
of the sheet metal the gap between the plastic part and
the metal sheet as shown.
Caution!
Before gluing check the correct positioning of the
sealing tape. The gluing must be done carefully to
ensure that the gaps are closed, and no water can
splash through.
Sealing of the right side with the last sealing tape
Use 1 pcs. of the 3 cm long sealing tapes to seal the
gap between the sheet metal and the plastic wall at the
right side of the sheet metal.
Caution!
Before gluing check the correct positioning of the
sealing tape. The gluing must be done carefully to
ensure that the gaps are closed, and no water can
splash through.
2. When the sheet metals with the plastic part are
completely sealed follow the working steps on page 1
& 2 in the reverse order and use the new screws to fix
the outer housing.
Caution!
Place the plastic clip with the temperature sensor at the
same position at the evaporator (Page 2).
Make sure the cables do not touch any components on
the control PCB (heat sink, etc.) and that the cable of
the water level switch will not touch the edge of the
sheet metal after reconnection.
Check whether the condensate hose and cables are
routed and fixed at the same (correct) position.
NOTICE: When reassembling the unit make sure that no cables are pinched and all lose parts (cable tie residues, etc.) are removed fromthe system.
Check the function in a concluding test run.
