The oil that came out of the circuit during the repair must be properly collected (rags, ....) and treated
appropriately. Do not throw freely in the environment.

FEATURES AND REQUIREMENTS
1.1
THE 3010 ¾” VALVE
,
The 3010 ¾” valve is a two speed mechanical valve with the following features:
pump flow : 12-23 l/min
pressure range 12-50 bar
oil temperature range : 10
– 70°c
1.2
THE FLUID
GMV
use and recommend an hydraulic fluid that :
-
Thanks to classification as ISO-L-HFDU category according to ISO 6743-4 and
its biodegradability index > 70%, according to standard OECD 301 B, is
acceptable from an environmental point of view.
-
Thanks to the synthetic base and its viscosity index (>180), higher than the
traditional mineral oil, allowing greater stability, ensuring better performance
against wear and aging on systems as lifts for persons and goods, in
accordance with the environmental directive 2006/118/EC.
-
Thanks to a flash point above 300°C compared to the 140°C of the traditional
mineral oil it is safer and reduces the risk of fire.

INSTALLATION OPERATIONS
WARNING
During installation operations never disable safety devices or directly power the pump motor.
2.1
HYDRAULIC CONNECTIONS
-
Before starting the installation, you should verify the structural and spatial limits within which you will
work. Consider the mounting methods you are going to use. It is therefore advisable to consider in
advance all conditions affecting the different working procedures and therefore do not take any action
without first considering the consequences. Make sure that the products received are complete with
everything you need and that all products and parts are not damaged during transport.
-
Data written on the label should be compared with the order form.
-
During the storage period, keep the material in the original container, protected from weather and direct
sun exposure, in order to prevent accumulation of water / condensation which may occur inside the
package. (See Technical data for the range of temperature and humidity). After removing the product,
the packaging material must be properly disposed of, as required by local law. Before recycling should
verify the nature of the various materials and recycle as prescribed.
-
GMV is not responsible for any damages caused by manual modifications (or changes) of the
packaging material done by others.
-
Any use of the facility, which is different from the original proposal situation should be discussed with
GMV. An application or use not permitted by GMV (patent legal reasons, technical or otherwise) is
under the installer responsibility and may affect the warranty.
-
For the installation or replacement of the hydraulic system components, observe the following points
-
Always place the elevator on the puffers;
-
Make sure the elevator cannot operate accidentally, blocking the main electrical switch;
-
Before opening any part of the hydraulic circuit, remove or unscrew the caps is always necessary to
bring the oil pressure to zero.
-
In case of welding operations,be care to prevent any contact between the oil and the piston rod, its
seals and other resilient parts that could be damaged;
