1.1. Marking

1.2. Simplified analysis of potential sources of electric shocks

With the use of non-flammable products (as defined in the standard EN 50059-2018 Annex C),

the risk of ignition is by definition nil or low, but on the other hand, these products contain large

quantities of water which quickly store quantities of energy sufficient to cause electric shocks

that would exceed the limits as defined in the standard EN 50059-2018 Annexes A and B.

That is why the ISOCUBE insulating cabinet is equipped with systems to prevent this type of risk.

Potential source of elec-

tric shock Measures Means applied

arises. On a temporary basis, conduction caused by condensation may arise.

•The ISOCUBE isolating cabinet must be installed indoors, outside installation is strictly pro-

hibited.

• The ISOCUBE insulating cabinet must be installed outside the coating area.

• The hand-held electrostatic projection equipment can only be used in designated pro-

jection spots in accordance with Standard EN 16985 or under equivalent ventilation con-

ditions.

• This equipment must not be used in a cab or an application room for solvent-based paints,

flammable liquids or ones which form explosive atmospheres.

• The use of this equipment in a work area for the application of electrostatic flammable

products or ones which form explosive atmospheres is dangerous.

• The ISOCUBE consists of the projection spray gun, the control module, the hose, the pump

and the product tank, which must be considered as a whole. Any technical change can

increase the stored electric energy in the whole set to a dangerous degree. It is strictly for-

bidden to modify the equipment.

• Install the isolating cabinet away from any explosive zone.

• Servo-control the isolating cabinet to the “on” position of the booth’s suction fan.

• Correctly connect the control module to the installation’s ground terminal.

nected to the circuit by the crocodile claw.

• Connect all metal parts of the installation (paint pumps, containers, stools, spin coaters,

etc., which positioned within three meters of the spray gun to the ground.

• Keep the spray zone clean and free of all unnecessary components.

• The floor where the operator works must be antistatic (either unclad concrete flooring or

a metal grating). Never cover the floor with an insulating covering. In potentially explosive

locations, the floor assemblies must be antistatic, in accordance with Standard EN 61340-

4-1.

• The use inside the booth of an uncovered flame, any incandescent object, a device or

object capable of generating sparks other than the gun is strictly prohibited.

It is also prohibited to store in the vicinity of the booth or in front of the doors flammable

products or containers in which such products had been stored.

• The jars and cans containing paint or solvent must be systematically closed after use.

• The supply pump of the paint used must have a maximum ratio of 18:1 for the Nanogun

Airmix® H2O 120 bar and 34:1 for the Nanogun Airmix® H2O 200 bar. The pump’s air inflow

must be equipped with a safety relief valve (supplied) to limit pressure to a maximum

value of 6.5 bar.

•Inside an explosive zone, it is prohibited to use electrical or non-electrical equipment that

has not been certified, like electrical extension cables, surge protector power bars,

switches, etc.

1.6. Rules of use

• Verify the extraction ventilation system efficiency on a daily basis.

• Once a week, verify the adequate operations of the ventilation system servo controls.

• Correctly ground all metal parts of the booth, along with the parts to be painted. The

resistance relative to the ground must be less than or equal to 1MΩ (for a 500-V voltage

measurement). This resistance must be regularly checked and, in any case, at least once

a week.

Index revision : B - September 2019 8 7120

• Ensure that anyone entering the spray zone is wearing the antistatic shoes in accordance

with Standard EN 61340-4-3. The measured insulation resistance must not exceed 100MΩ.

Index revision : B - September 2019 9 7120

2. Description

This equipment is designed for the application of water-based or water-thinnable hydrosoluble

paint or varnish. The liquids sprayed must be non-flammable and highly conductive to

electricity.

To apply paints of this type electrostatically, the most simple and most effective way is to place

the liquid under high voltage, and electrically isolate the paint supply system.

The ISOCUBE isolating cabinet consists of:

•of a Nanogun Airmix® H2O spray gun (Item1) (see RT Nr 7118),

• an electropneumatic box (Item 2) including the GNM 6080 control module (Item 3),

•A pump unit (Item 4) supplying the gun,

• A 60kV short circuiter located on the top of the cabinet,

• a stirrer (Item 5) as an optional extra.

• a product pressure regulator (not shown) as an option.

The ISOCUBE cabinet is equipped with safety systems that protect the operator against elec-

trical shocks, by blocking access to the parts under high voltage.

3. Characteristics

(*) - The measurement of the viscosity of a water-soluble paint using a consistometric cup leads

to very significant errors. In effect, these paints are thixotropic: their viscosity decreases with the

intensity of agitation and with the time for which they are stirred. At rest, these paints are highly

viscous substances; in contrast, in movement, they become not very viscous substances. The

viscosities shown are indicative for paint stirred just before being measured with a cup.

(**) - Any other use is prohibited

4.6. Start-up

WARNING : The complete start-up is done by "double clicking" the green button.

The first press triggers the compressed air supply for the pump, the regulator (if present) and the

ventilation of the cabinet.

This makes it possible fill, flush and/or bleed the product circuit quickly, and this action is func-

tional even if the door is open or unlocked.

The second press triggers the power supply to the GNM 6080, the compressed air required for

the spray gun, for the stirrer if it is present, for the short circuiter and its ventilation, and the

ISOCUBE is then ready to operate. If the door is left open or not locked, this second press has

no effect.

4.6.1. Placement of the paint drum

• Place the paint drum on the receptacle in the isolating cabinet, covered in its cover. It is

important to put the cover on to avoid the hose coming out under the effect of the pres-

sure of the product.

• Make sure that there is no product dripping onto the receptacle for the drum.

4.6.2. Priming the pump

WARNING : To start the pump, you must:

• Open the door in order to allow the equipment to discharge to the earth.

• Pour the vaseline oil into the cup (= cylindrical part in which the piston rod is located),

except FLOWMAX type pumps which do not require lubrication.

• If there are priming difficulties (pasty coating product), start the priming with water to fill

the hoses, then replace the water with the coating product.

• It is important, for the life of the pump, not to allow it to run unprimed(operating at more

than 30 cycles/min).

4.6.3. Ventilation

Check internal ventilation:

• Switch on the Isocube cabinet. Press the

green button once. Open the door.

•Place a finger on the ventilation outlet at

the top left of the cabinet. A light blast of

air must be perceived (pressure 0.1 bar +0.1

-0).

Booth ventilation: see § 1.5 page 7 alinéa 3.

4.7. Settings and operating modes

•Compressed air pressure (Item 1):

The equipment has an air exhaust valve which bleeds the air from the network if the pres-

sure is greater than 6.5/7 bar.

In this case, you will hear the noise of air bleeding: lower the air pressure in the network.

•Product pressure regulator (Item 2):

The regulator product is virtually never used in the 200 bar version and is very rarely used

in the 120 bar version. This setting is also easily accessible depending on the stop. The

product supply pressure at the spray gun is directly adjusted by actuating this pressure

regulator.

•Pressure pump power supply(Item 3):

The supply pressure of the pump must be adjusted in the following manner

For the 120 bar versions: From 0 to 6.5 bar based on the product to be sprayed

Pressure of the product coming out of the pump = air pressure x 15

For the 200 bar versions: From 0 to 6.5 bar based on the product to be sprayed

Pressure of the product coming out of the pump = air pressure x 30.

•Air pressure on the stirrer (Item 4) (option) :

Between 2 and 4 bar depending on the viscosity of the product, and the rotation speed

of the propeller must be adjusted using the needle valve on the engine.

•Spraying air supply pressure(Item 5):

From 1.4 to 6 bar depending on the product's viscosity and flow (see RT Nr 7118).

Beyond 4 bar, the de-solvation of the product and the production of mists can increase

significantly.

WARNING : Do not modify the pressure setting of the valve, as the proper functioning of the

pump depends on it. It is very important to use de-oiled and drained compressed air to

ensure the proper functioning of the equipment.
