Danger to the unit
➤
A change of the mixing ratio may have the consequence of the change of the pres-
sure ratio and a required change of the maximum allowed compressed air pressure.
The installed safety valve must be changed. In this case you get from
an
exchangeable nameplate with the new now valid data of the 2K-unit.
We recommend strongly to consult
in this case.
➤
The unit should never be operated without safety valve!
Should the safety valve need replacing, please see the machine card for its order
number.
With new safety valves take care that these are set and leaded at the maximum allow-
able inlet compressed air pressure of the
DUOMIX (see nameplate/machine
chart) corresponding to the mixing ratio.
➤
During operation, ensure that sufficient feed of material is available to the pump in
order to avoid heating due to friction, caused when the material pump runs dry.
Observe closely:
➤
no empty feed containers may be present during operation.
➤
the suction system may not be clogged, buckled or defect in any other way.
➤
if the unit stops processing material, shut it down immediately.
➤
The maximum operating pressures are to be adhered to in principle for all
parts (eg. pump, heater, hoses, gun, safety valve).
By differing allowable operating pressures, the lowest value is always the maximum
allowable operating pressure for the entire system.
General example:
Pump
up to 420 bar
Material hose
up to 600 bar
Spraying gun
up to 500 bar
The maximum allowable operating pressure for this example would be 420 bar.
Danger through explosion
➤
Never spray solvents or materials containing solvents into a narrow-necked can or
barrels with bung hole!
DANGER OF EXPLOSION!
➤
Please, always use an open container. Due to possible electrostatic charges, it is
imperative to ensure that the spraying gun has contact to the container walls when
working with metal containers.
It is possible for a static charge to occur due to the high flow speeds during the airless
spraying procedure. Static charges can lead to fire and explosions.
The equipment must, therefore, always be appropriately grounded (picture 2.3).
The original
DUOMIX is fitted with a ground cable as standard. If lost or
defective, please, order an immediate replacement (for order no. please refer to the
machine card).
➤
Never use this equipment outdoors during a thunderstorm.
➤
Due to electrostatic charges, only conductive material hoses should be used. All
original
material hoses are conductive and compatible with our equipment.
The maximum admissible working pressure on the hoses must correspond to the
maximum operating pressure of the unit.
