Switch on the heating system
➤
Roll out the hose package completely.
➤
Adjust the desired temperature in the display.
In this respect follow the notes in chapter
“3.11.2 System control”, p. “3.11.2 Sys-

➤
Switch on the heating.
Wait until the material has been heated up to spraying temperature.
The switch only lights
during the heating
phase. Once the
nominal temperature
is reached, the light
in the corresponding
switch goes out.

Pressure equalization of both components
Due to the differences in material characteristics of
and
com
-
ponents, the pressure in the system may have increased differently during the
heating phase.
For optimal working results we recommend a maximum pressure difference of
10 - 20 bar / 145-290 psi between both components.
Note!
The specified pressures
are only guide values
and,
depending on the
viscosity of the material
or the hose length used,
may need to be adapted.
Note!
The nominal tem-
peratures of the material
flow heaters are reached
much faster than the
temperatures of the hose
package. Therefore switch
on the hose package first
and the heater for the
material flow heating with
a slight delay.
To be able to achieve an
optimal spraying result,
the entire system, includ
-
ing the hose package,
must have been heated
up to the pre-set tempera-
ture,
before spraying is
started.
Attention!
If the pressure of the me-
tering pump is set too high
during the heating phase,
the pressure of one of the
components may increase
to overpressure ad thus
switch off the equipment.
You should therefore
ensure a low pressure
setting!
