Notes on safety
Caution
These Installation and Maintenance Instructions apply only to WOLF KG and KGW
Standard air-conditioning units.
The persons charged with the installation, initial operation or maintenance of the
equipment must read these instructions before commencing work.
Compliance with these instructions is mandatory.
Non-compliance with the installation or maintenance instructions voids the WOLF
guarantee.
The following symbols and warnings are used in these Installation and Maintenance Instructions:
Non-compliance with notes marked in this way can endanger persons.
Non-compliance with notes marked in this way can result in damage to the air-
conditioning unit or its components.
In addition to the warnings in these Installation and Maintenance Instructions,
adhesive warning labels are affixed to the air-conditioning unit.
Compliance with these warnings, too, is mandatory.
- Installation, initial operation, maintenance and operation of the air-conditioning
unit must be entrusted to adequately qualified and trained persons.
- All work on electrical systems must be performed by a trained and qualified
electrician.
- Work on electrical systems is subject to VDE regulations and the regulations
of the local power utility.
- Operate the air-conditioning unit only within the nominal range specified in the
WOLF technical documentation.
- Use as designated by the manufacturer is use solely for the purposes of
ventilation.
Atmospheric air is the only permitted medium.
This air must be free of noxious, flammable, explosive, aggressive, corrosionpromoting or otherwise hazardous constituents.
(Air-conditioning units rated "Ex-Schutz" in compliance with VDMA Guideline
24169/1 (suitable for use in hazardous environments) can be used to handle air
mixed with explosive gases, vapours or mists in accordance with the equipment
ratings for hazardous-environment classes 1 and 2).
- Do not remove or bypass safety devices or monitoring devices, or render such
devices ineffective in any other way.
- Do not operate the air-conditioning unit unless it is in perfect working order.
Faults and damage detrimental to or potentially detrimental to safety must be
repaired immediately by a specialist.
- Use only genuine WOLF components as replacements for damaged or defective
parts and components.

Delivery to site / Transportation
Delivery to site
Transport
Caution
KG 15-250 and KG/KWG 630-1000 series air conditioners are delivered to site in
transportable units.
Check all incoming goods for signs of damage in transit.
Make a note of all damage or suspected damage on the waybill and have this
damage report countersigned by the delivering freight forwarder.
Immediately report the situation to WOLF.
The equipment must always be transported right way up, in other words in the
position corresponding to the as-installed position.
Exception: KGXD 160/250 upright is transported on its side (turned through 90°).
Use straps of adequate load-bearing strength to carry the suspended load.
If you use a fork-lift or rollers to move the equipment, always make sure that the
forks or rollers are beneath the frame sections, not beneath the floor panels.
If you suspend the load by means of eyebolts (on request), make sure that the
length of each rope run is at least equal to the distance between the eyebolts L.
Make sure all ropes are the same length.
The weatherproofed KGW 630 to 1000 air-conditioning units are fitted with lifting
eyes as standard.
Always use cross-bars when lifting items of equipment fitted with more than four
eyebolts.
Clearances
Clearance on the operating side should be at least equal to the width of the unit
to permit access for installation, operation and maintenance (see list below).
Space required for installation, operation and maintenance:
Fan section 0.8 x width of unit
Chiller, heater section, KVS 1 x width of unit + 250 mm
Filter section up to KG 100 1 x width of unit
KG 160 and larger 0.5 x with of unit
In a side-by-side configuration, allow the clearances as stated above for installation, operation and maintenance on each side.
Those units which require a siphon (washer, humidifier, chiller, KGX/KGXD, drip
separator) must be installed in such a way as to ensure correct installation and
operation of the siphon (do not forget to allow for height of foundation).
In Germany, special statutory conditions apply to extractor systems for enclosed parking lots. Comparable legislation may apply in other countries.

Notes on installation
Foundation Install the units and components on a surface which is smooth, level and of
Caution
adequate load-bearing strength.
KG 40-250:
The base frames must be horizontal and the foundations must be smooth-topped
and horizontal.
Make sure that the bottom of the frame is in full-face contact with the supporting
surface: spot support is not permissible.
Insulating strips
(by others)
Permanently elastic inserts must be placed between supporting surface or
foundation and air-conditioning unit or, more accurately, base frame, in order to
prevent the operating noise of the air-conditioning unit carrying into the building as
structure-borne sound. By prefence, these inserts should be in the form of
insulating strips placed lengthways under the sectional frame members.

The units and components must be installed on a base frame or strip foundation.
Height to suit local snowfall, min. 200 mm.
X = width or length of unit, as appropriate - 20 mm
The base frames must be horizontal and the foundations must be smooth-topped
and horizontal.
Make sure that the bottom of the frame is in full-face contact with the supporting
surface: spot support is not permissible.
Permanently elastic inserts must be placed between supporting surface or
foundation and air-conditioning unit or, more accurately, base frame, in order to
prevent the operating noise of the air-conditioning unit carrying into the building as
structure-borne sound. By prefence, these inserts should be in the form of
insulating strips placed lengthways under the sectional frame members.
Do not set down the unit on a flat surface, as this would damage the drip nose (see
drawing). Use wooden battens of adequate thickness as supports to avoid this
difficulty.
