Info
Assembling the heatable hose occurs in reverse order. Tighten the hose fitting only by
hand first. Permit the heatable hose and the manual application unit to heat up to approx.
100 °C before finally tightening the screws.
While tightening the hose fitting, make sure that the spray hose does not become twisted.
Refer to the circuit diagram in Chap. 2.2 when connecting the electrical lines.
When replacing the half shells, make sure that the flat portion of the arresting bars on the
inside of the half shell are seated properly on the corresponding counter pieces at the
heating cylinder.
