IntendedUse 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

andconditioningofnormalair.Thisincludestheltering,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!

Unintendeduse 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-

rioustohealth,inammable,explosive,aggressive,corrosiveordangerousinany

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.

Airconditioningunitsforthetransportofinammableorexplosivegasesmustbe

specially designed. Normal air conditioning units may not be operated in these dan-

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

Technicaldescription Wolf air conditioning units are central air conditioning units and are used for the sup-

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

themostdiverserequirementsforairconditioningtobemetbyconguration.The

transportedaircanbeltered,heated,cooled,dehumidiedandhumidied.

InformationSigns/Safety

Instructions

3062049_201610

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-typeheatexchangers(subjecttotypeandsize)andheatwheelheat

exchangersarelaidat(turned90°)fortransportation.

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

ontheoorpanels.

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.

Iftheoccurrenceoffrostatthenallocationcannotberuledout,adoptsuitablemeasures

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

Spacerequirements 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

Inback-to-backcongurationswithside-by-sideunits,leaveclearancesasstatedabove

on both sides for installation, operation and maintenance.

Install units that require a siphon (scrubber, humidier, 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).

Itisadvisabletoinstallawaterprooffoundationforunitswithhumidiersand/orcooling

coils installed above rooms containing moisture-sensitive equipment (e.g. IT rooms, etc.).

Delivery / Handling

3062049_201610

KG TopInstallationinstructions

Equipmentinstallation 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.

Appliance example - top view:

Note

When installing high or perhaps smaller appliance components (e.g. RWT, RWT duct

components or standing appliance layouts with several components above each

other),securetheseduringassembly/installationagainsttippinguntiltheyarenally

connected to other components that ensure that tipping is prevented.

Requires permanent securing against tipping over.

Note

Baseframe/foundation

base

Internalunitbaseframe

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.

10 3062049_201610

KG TopInstallationinstructions

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).

Baseframesmustbehorizontalandperpendicular;thefoundationbasemustbelevel

andhorizontal.

Weatherproofdevicesmaynotassumeanybuildingsupportfunctions

ortasksoftheroofofthebuilding(VDI38035.1/BSEN130536.2).

Thelowerbaseframemustmakefull-surfacecontactwiththebase;

padorpointcontactisnotpermissible.

Note

It is essential to ensure that the base on which the units and components are to be

assembledandinstalledislevel,horizontalandofadequateload-bearingcapacity.

Thebaseframemustbehorizontal,andthefoundationmustbelevelandhorizontal

(check with browning rod).

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.

Provideapermanentlyexiblelayerbetweentheinstallationsurfaceorfoundation/plinth

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.
