LEGAL NOTICES
WARNING CONCEPT
These instructions contain information for your personal safety and to prevent material damage. Information for your
personal safety is denoted by a warning triangle. Information pertaining to material damage only has no warning
triangle. The warnings are grouped according to these levels of risk:
DANGER indicates that death or serious injury will result if proper precautions are not taken.
WARNING indicates that death or serious injury can result if proper precautions are not taken.
CAUTION with warning triangle denotes that minor injury can result if proper precautions are not
taken.
CAUTION without warning triangle denotes that material damage can result if proper precautions
are not taken.
BEWARE denotes that an undesirable event or state can result if the relevant advisory is not heeded.
Should there be more than one level of risk, the warning for the highest level of risk is always used. A warning about
personal injury with a warning triangle may also include a warning about material damage.

1 SYSTEM OVERVIEW
The GS62 was developed for the ventilation of rooms with outside windows in single and multiple occupancy
houses, hotels and guest houses. It is an air extraction system that works without heat recovery and with direct
current.
Application areas
The GS62 is fitted into the outside wall of a building and can be used for:
• Bathrooms / toilets
• Kitchens
• Utility rooms
• Hallways
Variants
The base element of every variant is the combination of wall mounting sleeve (1), fan housing (2) with integrated
fan (3) and the GS61 PSU.
GS62 base element GS61 PSU
The GS62 can optionally be connected to the following modules, offering extended functionality as compared
to a standard On/Off switch*):
• R60 controller
• Delay switch
• Hygrostat
Note - The description and connection options of these modules are in additional,
accompanying installation and operating instructions for the GS61 air extraction system.
Interior room side
The ventilation system is covered by a baffle on the interior wall side. Inside baffles can be
ordered:
• in colors white/silver/stainless/gold (material: is plastic, curved shape)
• in opaque glass (straight shape)
• as a frame for affixing a glass or ceramic tile (material: plastic, straight shape)
*) The On/Off switch is not included in the delivery

Exterior room side
In the direction of the exterior room side, the ventilation system can be closed either with a
• protective hood (white/gray/bare1) ) or
• the GS62-Corner 500 / GS62-Corner 1000, depending on preference and practical requirements
The GS62-Corner is used mainly when a building is retrofitted with insulation as part of renovation measures.
The air duct is embedded in the insulation and the airflow is directed out in the window reveal.The wall opening
for the ventilation system must therefore be in close proximity to the window. The GS62-Corner 500 is used
for a 250 … 450mm distance, the GS62-Corner 1000 for a 451 .. 950mm distance, between wall opening and
window reveal.
Validity
The installation and operating instructions apply for these elements:
*) Install only after coating (by customer) with Nano Set ,included
**) Not stock items (lead time on request)

OPERATING CONDITIONS
3 OPERATING CONDITIONS
Caution - Only use the GS62 in rooms that are free of aggressive and caustic gases, and
extreme dust exposure.This will ensure reliable functioning of the fan.
3.1Telescopic tube
Standard variant
The length of the standard variant of the telescopic tube is 550mm, meaning it can be used for maximum wall
thicknesses of 550mm. For wall thicknesses of 325 ... 550mm, the telescopic tube is continuously adjustable.
The sleeve can be shortened by a maximum of 150mm for wall thicknesses shorter than 325mm.
Note - The minimum permitted wall thickness when using the standard variant of the telescopic
tube is 150mm.
The sleeve of the telescopic tube on the interior wall side is covered by the fan housing and an Inside baffle.
Extension
An extension is available as an option for walls having a thickness from 550mm to 1000mm (maximum). The
extension is a second telescopic tube without fan. The order number for the extension is under Validity in Sec-
tion System overview.

3.2 Flat duct (GS62-Corner)
The length of the flat duct (GS62-Corner 500) is 500mm, and so can be used for gaps between wall open-
ing and window reveal of 250 ... 450mm. If the gap between wall opening and window reveal is greater than
400mm, a flat duct 1000mm in length can be ordered as an option (GS62-Corner 1000).
Note - The maximum permitted gap between wall opening and window reveal is 950mm.

Note - Keep a minimum distance of 100mm from the center of the wall mounting sleeve to
walls, to components in the interior area as well as to fixtures and fittings.
Wall holes and cable laying
Danger - Make the opening for the wall mounting box outside protective areas 0 to 2 of the
room. This will ensure that no moisture can penetrate in.
1. Make two holes in the masonry - one (Ø75) for the wall mounting box and one (Ø115) for the telescopic
tube. Ensure that the hole for the wall mounting sleeve of the GS62 is at an angle of 1-2° to the outside
wall so that condensation is drained away reliably.
2. Lay the 2-wire connecting lead (red/white) for the wall mounting box in the cable duct such that the cable
ends project out of each wall opening by at least 150mm. This ensures that the PSU and switch can be
connected with terminal blocks.
Note - The dimensional drawings for all holes are in Section Dimensional drawings.

2. Align the telescopic tube at an angle of 1-2° to the outside wall Use
polystyrene or wood wedges for securing.
Note - GS62 with protective hood:
Ensure that the two elements for securing the protective
hood (4) to the outer wall protrude no more than 2mm.
GS62 with GS62-Corner:
Ensure that the telescopic tube protrudes 10-15mm on the outside
wall.This ensures that the flat duct can be fitted correctly. Before inserting the telescopic tube,
turn the two brass sleeves upwards and affix the all-round sealing tape (included) at a distance
of 8mm from the outer edge of the telescopic tube (see Figure 11: no.
)
3. Use 2-component foam to fully foam the free area between the masonry and
telescopic tube (2).
4. Cut the installation foam inside and outside flush to the wall.
5. GS62 with GS62-Corner: Stick sealing tape all around the projection of the telescopic tube.
Caution
- The GS62 is not suitable for drying out buildings. Do not use the GS62 whilst con-
struction work is being carried out in the building. Close the telescopic tube to protect the fan.
This safeguards reliable functioning of the GS62 following completion of building work.

Note: The polystyrene spacer, if still in, and any dirt residue must be removed from the tele-
scopic tube before the fan housing is fitted. Also, the 2-wire cable for connecting the fan to
the PSU must be wired at the designated place (7).
1. Remove the housing screen (1) and housing cover (2) from the fan housing (3). Undo the two screws to
remove the housing cover. The housing screen is clipped on.
2. Before final installation, drill four holes (Ø 6mm) in the wall for the wall attachment (9). To do this, position
the fan housing into the telescopic tube (6) from the interior wall side, align it and mark the places for
drilling at the four external holes for wall attachment (9) of the fan housing. Remove the fan housing, drill
the wall holes and insert the dowels (included).
3. Position the fan housing (3), including nonreturn valve (5), into the telescopic tube (6) from the interior
wall side. Before pushing the housing all the way to the wall, route the 2-wire cable for the fan and PSU
connection through the cable feedthrough hole (7).
4. Push the fan housing all the way to the wall and attach it to the masonry using the four screws (included)
at the four external holes for wall attachment (9).
5. Connect the cable in the fan housing to the connectors provided. Information on this is in Section Elec-
trical connection on Page 23.
