GENERAL INFORMATION
General conditions
Product liability
In relation to product liability the current rules under Danish
law shall apply.
The Seller shall never be held liable for operating losses,
loss of earnings and other indirect losses.
Product liability insurance which includes cover against
injury and property damage has been taken out.
Any disputes between the parties shall be settled by the
Maritime and Commercial Court in Copenhagen (Sø- og
Handelsretten) in pursuance of Danish law
Transport and storage
Transport and storage must be in the range of limited
environmental condition:
Temperature between -10 and +40°C / 14 and 104°F
Relative air humidity between 30 and 70 %
Air pressure between 70 and 106 kPa
(See symbols page 8)
Warning!
Do not modify this equipment without authorization of the
manufacturer.
Installation in corrosive surroundings
Special guidelines must be observed when installing the
rail system around swimming pools, etc.
The surfaces of the brackets used, traverse travelling
trolleys, etc., must be painted. Hoists must be supplied
with a special surface treatment.
All fixing elements, nuts, washers, threaded rods, must be
acid-proof.
Acid-proof threaded rods and dual-component adhesive
must be used for installation in concrete, tiles, etc.
Through-going threaded rods or acid-proof screws must
be used for installation in wood.
Particular care should be taken to avoid damaging the
surface of painted components.
Washers made of synthetic material must be used in
between painted surfaces and nuts and ordinary washers.
Damaged paint must be repaired after installation, and
visible threaded rods, nuts, washers, etc., must be covered
with paint.
Hidden threaded rods, nuts, washers, and brackets in the
rail track must be treated with a silicone coating.
Wherever possible, nuts must be fitted with protective
caps.
There must be no swarf, dirt, or other impurities in the
rail system as they will accumulate moisture and lead to
corrosion.
Bearings in traverse travelling trolleys must be treated with
a silicone coating before installation.
Guldmann recommends that in corrosive surroundings like
swimming pools, bathing environments etc., regular safety
and service inspection at rail systems and ceiling hoists
must be performed every ½ year. A complete overhaul of
the rail system (replacements of brackets, fixings etc.) can
be necessary approx. every 5 year.
Guldmann products are designed for use in these environ-
ments with the following maximum values of;
Water quality:
pH....................................... 7,6
Free chlorine, mg/l .......................... 2,0
Bound chlorine, mg/l ........................ 0,5
Air humidity:
The relative air humidity in the room should be approx.
70% at an outdoor temperature of approx. 20 degree C
and approx. 50% at an outdoor temperature of approx.. 0
degree C.
Note!
Quality designation for bolts, etc.
A4/AISI 316 = acid-proof
A2/AISI 304/rustproof 18.8 = not acid-proof
Torque settings
All bolts and nuts are tightened with torque in accordance
with applicable rules – M8 = 27 Nm, M10 = 54Nm.
Hilti HUS-H 8 x 65 screws are tightened with a torque of
35 Nm.
Hilti HUS-H 8 x 85 – 150 screws are tightened with a torque
of 45 Nm.
The two M10 nuts at the GH Plasterboard Wall bracket are
thightened with a torque of 30Nm.

GENERAL INFORMATION
General conditions
Placing a new Hoist in an existing rail system.
Please notice, before placing a new hoist in an existing rail
system it must be ensured:
• The rated max load of the rail system, must be equal or
higher than the max load of the new hoist.
– If there is no max load mentioned on the rail system,
the rail system must then be checked according
to the guideline in the Installation guide (distance
between bracket according to max load)
– If the brackets are not visible, then a load test with 1,5
x max load of the hoist must be performed minimum
20 min. The deflection of rails must not be higher than
1/200 of the length of the rail.
– If it is not possible to do any of the above mentioned,
please contact Guldmann or their representative.
• If the rail system can not be rated to the same max
load as the hoist, then extra brackets must be installed
according to the Installation guide (distance between
bracket according to max load).
Class I equipment
Fixed rail systems are class I equipment and must be
installed by a qualified technician or by Guldmann Service
Team.
Equipment is disconnected from Supply Mains by breaking
the mains breaker switch.
Class II equipment
Mobile equipment is class II epuipment (marked with dou-
ble-encassed symbol) and can be connected to the mains
direct by the user.
Equipment is disconnected from Supply Mains by detach-
ing the mains plug from the wall outlet.
Emergency stop device
The emergency stop device must be reset in order to con-
nect power to the product. To do this, push the yellow reset
button.
Spare parts
Only original spare parts must be used according to UL
approval.
Installing heavy duty rail systems
Bracket types must be chosen in accordance with the list
of components, certain types of bracket must not be used
in connection with these installations.
A heavy duty model traverse travelling trolley must be used
in connection with room-covering rail systems rated 500 kg
(1100 lbs).
The distance between brackets must be adapted to the
type of rail in question in accordance with the instructions.
Two installation elements, a glue anchor or expansion bolts
must be used per bracket when installing the system in a
concrete ceiling or wall, in accordance with the instructions.
Ceilings and walls made of materials other than concrete
must be carefully inspected and tested for suitability.
Special care should be taken when testing at 1.5 x the
rated load.
The strape shall be inspected at an annual inspection.
The patient is protected by free fall safety mechanics if the
timing belt failes.
The hand control and cable must be free from the hanger,
patient or any other object before the hoist is activated up
or down.
Note!
GH3 hoists may not be installed higher than 3000 m above
sea level.
Environment:
Condition of operation must be in the range of:
Temperature between -10 and +40°C / 14 and 104°F
Relative air humidity between 30 and 70 %
Air pressure between 70 and 106 kPa
(See symbols page 8)

GENERAL INFORMATION
Power supply
GH3 is equipped with batteries that require regular
recharging.
Fixed rail systems
Fixed rail systems must be installed by a qualified installer
or by Guldmann Service Team.
Equipment is disconnected from Supply Mains by breaking
the main breaker switch.
Use of Class I power supply to fixed rail systems is
Recommended (Fig. 1), but can be installed as Class II
where local legislation allows it (Fig. 2).
Fig. 1)
Class I power supply must be installed with ground wire.
Note: Class I power supply must only be used in perma-
nent installation.
Fig. 2)
Class II power supply must be installed without ground
wire and can be installed both permanently in mains power
outlet and with socket mains power plug.
Portable rail systems (free-standing)
Portable rail systems must be installed with class II power
supply for portable installations (Fig. 3).
Power supply for portable installations Class II (marked with
the double-encased symbol ) can be connected to the
mains direct by the user.
The transformer is disconnected from the supply mains by
detaching the mains plug from the wall outlet.

Protection against electric shock
Electrical installations
Protection against electric shock
These precautions apply to installations made in Denmark.
Local requirements may differ.
Guldmann ceiling hoist and rail systems are manufactured
and installed in accordance with the regulations of Medical
Electrical Equipment IEC/UL 60601-1.
Guldmann has a UL/DEMKO approval of its products
which confirms that they meet the requirements contained
in IEC/UL 60601-1.
This regulation defines how medical equipment must be
classified and also how it must be protected so that
danger of electric shock does not arise when handling
the products.
Guldmann transformer for fixed installed rail system is clas-
sified as equipment in Class I – High Voltage Regulation,
Medical Electrical Equipment.
Reference is made to Fig. 701A – Area Division 0 to 3.
Installation of the rail system is carried out with safety
voltage – designated SELV. The safety transformer
with a nominal voltage of 33 V AC voltage.
In accordance with the High Voltage Regulation,
Chapter 701 – AREAS WITH BATHTUBS OR SHOWERS
Chapter 701.4 Protection for safety reasons
When SELV is used (safety voltage), protection against
direct contact must be in place regardless of the size of
the voltage, i.e. to min IP2X.
The geometry of the live rails meets the requirements for
protection against contact.
Regarding installation of Guldmann rail systems
in bathroom environments
Guldmann power supply (transformer) and rail with
charging liner must be installed in accordance with
the illustrations in Fig. 701A & 701B and guidelines
interpreted here below.
Guideline for transformer:
• Transformer class 1 must be installed above 3 m
(9 3/4') if installed directly over areas 2 and 3.
Or above 2,25 m (7 1/4') if not installed directly above
areas 2 and 3 (outside area 3)
• Transformer class 2 must be installed above 2,25 m
(7 1/4') (area 3) if the mains power is protected by a
residual-current circuit breaker max. 30 mA (RCCB)
(HPFI-breaker “DK”).
Guidelines for single rail and room covering rail system:
• Single rail system without charging liner must be
installed above 2,25 m (7 1/4'), ground connection of rail
(area 3 and outside area 3)
Guidelines for rail system with open end:
• The rail with charging liner must be installed with end
cover and with a minimum clearance of 100 mm (4").
to the charging liner from the open rail end. (to apply to
IP20).
If e.g. cleaning by hosing, the power supply and charging
area must be located completely separate from the area in
which splashing with water may occur.
For single rails the grounding may be located as required
either in the bathroom or in the adjacent room.
Note
These rules have been issued by the Electricity Council
and form part of the High Voltage Regulation.
There may be special local requirements for the installation
of rail systems in medical treatment areas.
Any special requirements carried out without the partici-
pation of Guldmann are at the purchaser’s own risk.
See illustrations on page 20 + 21.
