Initial Operation; Connecting The Heating Hose To The Airless Unit And Spray Gun - Storch HotFlow Mode D'emploi

An excessively high volume flow rate (nozzles too large) or very low temperatures of the coating material
prior to use can be the reason for the temperature of the coating material not being reached. The ambient
temperature also has an influence on the heating properties of the hose.

4. 4 Initial operation

4.1 4.1 Connecting the heating hose to the airless unit and spray gun

The HotFlow 7.5 m heating hose system (art.no.: 691505) should not be connected to the following
STORCH airless units: LP 400, LP 460, LP 540, LP 690 and SL 1100.
The heating element on the hose is connected to the airless unit (note: the maximum operating pressure is
250 bar). If the heating hose is mounted on the hose reel, connect it to the airless unit using the connec-
ting hose supplied. The spray gun is to be connected to the other end. Firmly tighten all of the hose con-
nections using the corresponding tool. Attach the nozzle holder and selected nozzle onto the spray gun and
screw it firmly in place.
4.2 4.2 Connecting the temperature regulator to the mains supply and the heating hose
Before establishing the connection to the mains supply make sure that the mains voltage corresponds with
the details on the unit's type plate. Only connect the unrolled temperature regulator cable to a 230 V out-
let. Pressing the green „RESET" button causes the red control light to illuminate. The temperature regu-
lator is switched off by pressing the blue button. Now connect the control cable of the heating hose to the
temperature regulator.
4.3 1.1 Setting the temperature
The temperature can be increased or decreased in 1 degree increments using the membrane buttons at the
bottom left and right (marked with a triangle). After the desired value has been selected press the SET but-
ton within 3 seconds in order to save the value. If you want to adjust the value quickly, press and hold the
arrow buttons. If the power supply is interrupted, the calibrated temperature specified above will serve as
the basis value when the unit is restarted. This safety feature prevents a potentially sensitive coating mate-
rial from being overheated accidentally. The heating process can take several minutes to reach the desired
material temperature. This depends on the initial temperature of the coating material and the surrounding
environment (approx. 15 to 20 minutes). Please note that the outlet temperature is approx. 10% below the
selected temperature.
4.4 1.1 Displays and error messages
Displays
HI = Measured value is higher than the display range
LO = Measured value is lower than the display range
Error messages
F0 = Heating interruption (2)
F1 = Synchronisation error (1)
F2 = Error when saving (1)
F3 = Error during calibration (1)
F¯ = Window (upper limit) exceeded (2)
F– = Measurement defective (2)
F_ = Window (lower limit) not reached (2)
(1) = Static error display, restart by interrupting the power supply necessary
(2) = Error display flashes alternately - check cable - restart via mains
