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 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.

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, it must then be checked according to the guideline in the installation manual (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. The deflection of rails must not be higher than 1/200. • 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 there must be installed extra brackets according to the installation manual (distance between bracket according to max. load). 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 over 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.

Note! GH3 rails with charging liners must not be used in corrosive or dusty surroundings (areas around swimming pools and at riding schools). Quality designation for bolts, etc. A4/AISI 316 = acid-proof A2/AISI 304/rustproof 18.8 = not acid-proof

Electrical installations Protection against electric shock

Electrical installations These precautions apply to installations made in Denmark. Protection against electric shock Local requirements may differ. Guldmann ceiling hoist and rail systems are manufactured and installed in accordance with Medical Electrical Equipment UL 60601-1. Guldmann has a UL/DEMKO approval of its products which confirms that they meet the requirements contained in 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 ceiling hoist and related rail system are classified as equipment in Class I – High Voltage Regulation, Medical Electrical Equipment, Chapter 14.

Regarding installation of Guldmann rail systems in bathroom environments Guldmann power supply (transformer) must not be installed and charging of hoist must not be carried out in Areas 0, 1 and 2. Power supply and charging area must be located outside Area 2, but hoist and rails may be used inside the area. 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. If the rail system is only installed in the bathroom and not in other rooms outside the bathroom, the rails do not need grounding. Grounding must be done if the rails continue outside the bathroom and the lower edge of the rail is less than 3.0 m/ 120” above the floor.

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 24 V AC voltage. In accordance with the High Voltage Regulation, Chapter 701 – AREAS WITH BATHTUBS OR SHOWERS

Excepted are: Single rails hanging higher than 2.25 m/90” above the floor and not continuing into Area 0, 1 and 2. For single rails the grounding may be located as required either in the bathroom or in the adjacent room. The parallel rails do not need to be grounded.

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 meet the requirements for protection against contact.

Any special requirements carried out without the participation of Guldmann are the purchaser’s own risk.

Chapter 701.413.1.6 Additional equalizer Note Metallic pipes and ducts (Guldmann aluminium rails) which are only found in these four areas and are not conductive when in contact with earth or parts outside the areas do not have to be connected to the equalizers.

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.

GH3 – Before service start

Taking the hoist down from rail 1. When the trolley is applied with a pick-up for charging, unplug the plug and remove the wire from the groove.

2. Remove side cover on hoist, place your hand under the hoist and pull out the 2 connection shaft, yellow handle, out.

3. The hoist can now be taken down from the rail.

16

service

GH3 – Before service start

Before changing any Printed Circuit Board (PCB) or cables, you must use a anti-static set and unplug all batteries.

Place the hoist so the top cover is not damaged while working on the hoist.

17

service

GH3 – Demounting covers

Demounting side covers

Release the side covers from the top of the hoist by means of a gentle push on the fixing points on each side. The covers are tipped free of the hoist and can be removed.

Demounting finger protection Untighten the two srcrews on the finger protection.

Move the two clips down and remove the finger protection.

GH3 – Demounting covers

Demounting bottom cover Untighten the 3 screws on both sides of the hoist.

Release the 2 clips in both sides of the hoidst.

If the hoist is equiped with IR, the IR wire must be unplugged to remove the bottom cover.

GH3 – Replacement of lifting strap

Demounting the lifting strap Lower the strap completely so you can get hold of the slip at the top of the hoist.

Pull the strap out so you can take the pin out and take the strap out of the hoist from the bottom of the hoist.

21

service

GH3 – Replacement of lifting strap

Mounting the strap Take the new strap and introduce it through the strap wheel until you can reach the slip from the top of the hoist. Note: It is important to mount the strap correctly. Place the strap with the fold turned away from the led.

Replace the pin in the strap and pull the strap down from the bottom of the hoist, so that the pin and strap are replaced in the strap wheel.

If you have problems getting the strap through the strap wheel, it is because the strap wheel is a bit turned over.
