Water inlet

6.6. Air Connection

Before the unit is connected to the air
supply, the pipe system must be care-
fully rinsed in order to remove coarse
impurities.
• The unit requires an air supply boosting
- an inlet pressure of 2-6 bar
- a minimum capacity of 70 l/min.
• The air supply pipe is connected directly with a
quick fitting for easy dismantling. In all units an in-
let valve with 1/4" thread is fitted (layout drawings).

Supply of Detergent

See drawing no 110003498
• Place the can with detergent in the can holder
• Check the suction filter for impurities.
• Put the suction lance- into the can below product
level and avoid suction of air.
• After pre-rinsing, check again that the lance is suf-
ficiently below product level and avoid suction of
air during foam or spray operation.
• After use of and when changing product as well
as after use of the unit, remove the suction lance
from the can.

7. Operation procedures

7.1. Start up

7.1.1.

Start

1. Make sure that the water and air supply to the
unit is open. For air see layout drawing.
2. Use the unit according to the "User Guide".
7.1.2.

Stop

1. Close the water supply (layout drawing).
2. Close the air supply (layout drawing).
3. Deactivate chemical supply by pulling up the suc-
tion lance .
7.1.3.

Adjustment of detergent

Remove cover from the unit.
Adjustment of detergent can be done by means of the
limiting nozzle (layout drawing).
The limiting nozzle is placed in the suction nipple of
the non-retur valve (110003769) and can be replaced
with a smaller or larger nozzle depending on the con-
centration needed.
7.1.4.

Adjustment of air

Remove the cover from the unit. Press and hold down
"down arrow".
Adjust the air pressure on the reduction valve until an
appropriate foam quality is reached.
When setting the regulator, carefully
pull up the knob and turn it clockwise
for pressure increase and counter clock
wise for pressure decrease.

7.2. Maintenance, trouble shooting and Service

Maintenance Instructions
1. Quick couplings; it is recommended to lubricate
all couplings parts regularly, approx. once a
month) by water proof grease to prevent leaks
and damage of o-rings.
2. If the quick couplings leak, o-rings should be
replaced.
3. Depending on usage, maintenance should be
undertaken by an authorised service engineer at
least once a year in order to prevent defects and
