Using The Unit On Construction Sites And In Workshops; Working On Or Repairing The Electrical Equipment; Working On Electrical Components; Max. Operating Pressure - Storch HotFlow Mode D'emploi

1.10 Cleaning the unit with solvents
When cleaning the unit with solvents the heating element of the heating hose must not be
activated,as an explosive air/gas mixture can develop in the hose. The container into which
the solvent is pumped must be earthed. The top of the container (bucket) must be completely
open due to the risk of explosion (no small opening through which fluid is injected).

1.11 Using the unit on construction sites and in workshops

The mains connection should only be established via a special feed point with a residual current protective
device (INF ≤ 30 mA rating).

1.12 Working on or repairing the electrical equipment

No liability shall be assumed for any repair work carried out improperly. Repairs should only be conducted
by an authorised STORCH service centre.

1.13 Working on electrical components

Remove the mains plug from the socket before carrying out any work.

1.14 Max. operating pressure

The permissible operating pressure for the heating hoses is 250 bar. Do not use the heating hoses on paint
spraying pumps with a higher operating pressure if they have not been limited to 250 bar.

2. Application overview

2.1 Operational areas

The hot-flow heating hose system has been designed as an accessory for airless paint spraying equipment
whose operating pressure does not exceed the nominal pressure of the hoses (250 bar).
The heating hoses can be utilised to heat water and solvent-based coating material to temperatures bet-
ween 20°C and 80°C to optimise the atomisation process at the nozzle. In addition to ensuring an opti-
mised spray pattern this also makes it possible to avoid the additional use of solvents. Furthermore, it also
reduces material consumption. (This depends on the coating material being used and the set parameters).
The heating hoses are suitable for stationary use in workshops or on construction sites.
Caution:
The 7.5 m long heating hose is intended for use with the AirFinish airless unit from STORCH
and should not be connected to STORCH airless units from the LP or SL series. If you are
using a device supplied by another manufacturer, check whether the airless unit is designed
for 7.5 m hoses.

2.2 Processable coating material:

Water and solvent-based paint (observe the flash point of > 21°C), two-component coatings (observe the
pot life), emulsion paint and latex paint.
If you wish to use a different coating material please contact us first as it could adversely affect the functio-
nality and safety of the unit.
Only use coating materials that are suitable for airless units and observe the information provided by the
respective manufacturer (technical data sheets):
The properties of some coating material are destroyed through excessive heating. Some material can be-
come highly viscous when heated and damage the heating conductor in the hose.

2.2.1 Coating material with sharp-edged aggregates

These aggregates have a high wearing effect on the heating wire located in the hose and also on the hose
itself. This adversely affects the service life of the unit.

3. Unit description

All heating hoses are heated by an electric heating conductor located inside the hose.
The coating material is heated by electric current flowing through the heating conductor. The material's
viscosity level is reduced as a result of the heating process. The electronic components in the temperature
regulator continuously monitor the set heating temperature. The heating capacity of the hot-flow heating
system is technically limited.
