IntendedUse Intended use of the Wolf air conditioning units is exclusively restricted to their use for
ventilation purposes. The air conditioning units are to be used only for the transport
andconditioningofnormalair.Thisincludestheltering,heating,cooling,humidify-
ing and dehumidifying of the air. Compliance with the instructions supplied with the
appliance are also part of its use for the intended purpose!
Unintendeduse Uses of the appliance for purposes other than those described above are considered
unintended. Wolf GmbH accepts no liability whatsoever for damages resulting from
unintended use. The user bears the risk alone.
On no account may air be transported that contains any constituents that are inju-
rioustohealth,inammable,explosive,aggressive,corrosiveordangerousinany
other way, since these substances can otherwise be spread throughout the duct
system and the building and impair the health of people, animals or plants living there
or even kill them.

ger areas unless there are remarks to this effect in our technical documents.

ply and exhaust ventilation of rooms. The modular structure of the appliances allows

KG TopDelivery / Handling
Delivery KG Top air-handling units are delivered to site as transportable subassemblies.
On receipt of the incoming goods, check the unit or components to ensure no damage
has occurred in transit.
If damage is evident or if there is a suspicion that damage might have occurred, the
recipient must make a note to this effect on the freight papers and have this countersigned
by the carrier.
Notify WOLF immediately of such circumstances.
Always transport the equipment upright.
Exception:Plate-typeheatexchangers(subjecttotypeandsize)andheatwheelheat
exchangersarelaidat(turned90°)fortransportation.
Otherwise the internal components will suffer damage and this can result in malfunctions.
Handle the appliances with slings.
Tall appliances on a small footprint (e.g. RWT) are connected with an increased risk of
tipping over during unloading and handling on site.
This requires additional measures
on site to prevent tipping over (e.g. securing with straps).
If a forklift or rollers are used to move the units, always ensure that the forks or rollers are
located underneath the frame sections at all times, so that weight is never allowed to rest
ontheoorpanels.
With lifting eyes (available on request), use slings at minimum centres L between lifting
eyes. Ensure that the slings are of uniform length.
Always use a crane lifting beam to lift appliances with more than 4 lifting eyes.
On no account may cladding panels be removed in order to lift the device, since the
cladding panels are structurally integrated in the device's bracing system.
No additional loads may be lifted together with the transport unit supplied by Wolf.

Final location Always install KG air-handling units in rooms where frost cannot occur.
Iftheoccurrenceoffrostatthenallocationcannotberuledout,adoptsuitablemeasures
to prevent water-containing components from freezing. If an outside thermostat is
installed ensure it is adequately insulated to prevent the air-handling unit from shutting
down inadvertently (see frost protection measures, page 25).
KGW air conditioning units are designed to be installed outdoors.
Note
Spacerequirements Make sure a clear space equal to at least the width of the equipment units is available
on the operator side; this is the minimum space necessary for installation, operation
and maintenance (see the table below).
Footprint of space required for installation, operation and maintenance:
Fan section 0.8 x appliance width
Cooling coil, heating coil, KVS 1 x appliance width + 250 mm
Filter section up to KG 96 1 x appliance width
from KG 130 0.5 x appliance width
Inback-to-backcongurationswithside-by-sideunits,leaveclearancesasstatedabove
on both sides for installation, operation and maintenance.
Install units that require a siphon (scrubber, humidier, cooling coil, plate-type heat
exchanger, mist eliminator) in such a way as to ensure correct installation and operation
of the siphon (make adequate provision for the foundation height).

Equipmentinstallation Appliances for weatherproof installation must not take on any static load or act as a
substitute for the roof of the building.
When assembling and installing combined ventilation and extract appliances with heat
recovery (KGXD, RWT), observe the correct sequence of assembly and installation
(see diagram). For this, one complete appliance train should always be assembled/
installed completely. The second appliance should then be installed from the heat
recovery onwards.
This offers the most effective prevention of alignment errors and installation inaccuracies.

WOLF internal unit base frames (suitable only for internal installation) are always sup-
plied loose (in advance).
Base frames delivered loose are knocked down for shipping and must be assembled,
aligned and secured to the base on site in accordance with the instructions enclosed
with the base frame.

KG TopInstallationinstructions
A base frame or plinth is required for air-handling units installed as weatherproof version
to support the appliances and their components.
The height of the base frame or plinth is subject to the local snow depth; however, it
should be at least 180 mm.
Subject to the prevailing wind force, secure the appliances with bolts to the base frame
or plinth (observe the transmission of structure-borne noise).
Baseframesmustbehorizontalandperpendicular;thefoundationbasemustbelevel
andhorizontal.

It is essential to ensure that the base on which the units and components are to be
assembledandinstalledislevel,horizontalandofadequateload-bearingcapacity.
Thebaseframemustbehorizontal,andthefoundationmustbelevelandhorizontal

To prevent the inspection doors from jamming, the lower base frame must make full-
surface contact with the base; pad or point contact is not permissible.

and the air-handling unit to prevent the transmission of structure-borne noise from the
appliance to the building. Preferably, this intermediate layer should take the form of
insulation strips that are positioned longitudinally underneath the appliance frame or
underneath the base frame.
