2.2 Safety notes
Please remember that the unit works at high pressure and may cause
life-threatening injuries if used inappropriately!
Always observe and follow all instructions in this operation manual and in the
separate operation manuals of individual unit components and/or the option-
ally available accessory devices.
2.2.1 Operating pressure
WARNING
Unit components that do not comply with the maximum permissible operat-
ing pressure can burst and cause serious injury.
➤The specied maximum operating pressures must generally be complied
with for all unit components. In case of varying operating pressures, the
lowest value is always the one to be taken as the maximum operating
pressure for the entire unit.
➤Material hoses and hose assemblies must comply with the maximum
operating pressure, including the required safety factor.
➤Material hoses must be leak tight and free of kinks, signs of abrasion or
bulges.
➤Hose connections must be tight.
2.2.2 Risks caused by the spray jet
WARNING
The material is discharged from the spray gun under very high pressure.
Due to its cutting effect the spray jet can cause severe injuries by penetrat-
ing the skin or entering into the eyes.
➤Never point the spray gun at yourself, other persons or animals.
➤Do not hold your ngers or hands in front of the spray gun!
➤Do not reach with your hands into the spray jet.

2.2.3 Risks caused by electrostatic charging
WARNING
The high ow velocities associated with the Airless spraying method may
cause electrostatic charging. Static discharges can cause re and explosion.
➤Make sure that the unit and the object to be coated are earthed correctly!
➤Always use open containers!
➤Never spray solvents or materials containing solvents into cone-top cans
or drums with bunghole!
➤Stand the containers on a grounded surface.
➤When using metal containers watch out for contact between spray gun
and container wall.
➤Only use conductive material hoses. All original material hoses from
WIWA are conductive and perfectly adapted to our equipment.
2.2.4 Explosion protection
WARNING
Units that are designed without explosion protection must not be used in
workshops that come under the explosion protection ordinance.
Explosion-protected units meet the explosion protection requirements of Di-
rective 94/9/EC for the explosion group, unit category and temperature class
specied on the type plate or in the declaration of conformity.
The operator is responsible for determining the zone allocation according to the
Directive of EC 94/9/EC, Appendix II, no. 2.1-2.3 when observing the measures
of the responsible inspecting authority. The operator is responsible for checking
and ensuring that all technical data and markings according to ATEX corre-
spond with the necessary requirements.
Please note that several unit components have their own type plate with sep-
arate marking according to ATEX. In this case the lowest explosion protection
of all attached markings applies for the entire unit. Applications where mal-
functioning of the unit can lead to danger to personnel must be provided with
appropriate safety measures by the operator.
However, if agitators, heaters or other electrically accessories are additionally
mounted, one must check the explosion protection. Plugs for heaters, agitators,
etc. that do not have explosion protection, may only be plugged in outside of
areas that fall under the explosion protection ordinance, even if the accessory
equipment as such is explosion protected.
WARNING
Heating up cleaning agents can cause an explosion. This may result in seri-
ous injury to persons and damage to property.
➤Pay attention to the ashpoint and the ignition temperature of the clean-
ing agent.
➤Switch off the material ow heater if you need to perform the following
work: Cleaning, pressure testing, decommissioning, maintenance and
repair.

Unit description
3 Unit description
The FLEXIMIX 2 is an electronically controlled two-component coating unit with
a freely adjustable mixing ratio.
The metering pumps feed the individual components to the metering valves.
The stroke length measuring system on the metering pumps thereby sends
signals to the unit control. The unit control then opens or closes the hardener
metering valve (component B) in accordance with the mixing ratio specied,
and injects the hardener into the freely owing standard component.
For the application of materials with higher viscosities the unit can be equipped
with optional accessories (e.g. feed hoppers, feed pumps, material preheating
systems or material ow heaters).
Please refer to the enclosed machine card (technical data) for the specica-
tions of your unit.
3.1 Intended use
The FLEXIMIX 2is intended for the metered application of low to medium
viscous dual component materials with pot life values in excess of 3 minutes in
commercial and industrial applications.
Any other use is considered to be unintended. If you intend to use the unit
for other purposes or with other materials and thus not for the purpose for
which it is intended, you must ask WIWA for permission – otherwise the
warranty will be invalidated.
Intended use also includes compliance with the technical documentation and
adherence to the prescribed operating, servicing and maintenance guide-
lines.
3.2 Unit conguration
The FLEXIMIX 2is available in three basic types, which differ primarily by the
sizes of the metering pumps:
➤the PHOENIX series with a delivery rate of up to 72 cm² per cycle depend-
ing on pump combination (see Fig. 8 on page 20).
➤the PROFESSIONAL series with a delivery rate of up to 306 cm² per cycle
depending on pump combination (see Fig. 9 on page 21).
➤the HERKULES series with a delivery rate of up to 550 cm² per cycle de-
pending on pump combination (see Fig. 10 on page 22).
By default, all components of the unit are mounted together on one frame.
In the version with wall brackets the rack is omitted. Instead, the unit's compo-
nents are mounted on separate wall brackets. However, this has no inuence
on the function of the unit.
The three basic types of FLEXIMIX 2are each available in two versions:
➤the standard version is equipped with a control cabinet which is designed
for the control of two metering valves,
➤the „Plus“ version is equipped with a control cabinet which is designed for
the control of up to four metering valves.
