2.2 Safety instructions
Observe the operating instructions for the spray device!
Material flow heaters are only used in conjunction with an
appropriate spray device depending on the design (high-pressure or
low-pressure) in high- or low-pressure processes and with appropriate
spraying accessories.
Inappropriate use can lead to severe injury.
➤ Read the operating manual of the spraying device and its accesso-
ries that are in use and follow the instructions the manual contains.
2.2.1 Operating pressure
WARNING
Unit components that do not comply with the maximum permissible oper-
ating pressure can burst and cause serious injury.
➤ The specified maximum operating pressures must generally be com-
plied with for all unit components. In case of varying operating pres-
sures, 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 Power supply
WARNING
Use in an area where solvent vapours exist can cause the power cable to
become porous or cracked.
➤ Therefore, the power cable must be inspected visually for damage
before each operation.
➤ Never make repairs to the power cable. It must be replaced completely
by a qualified technician.
WARNING
➤ Before connecting the Fluid Heater to the electrical supply, check to
ensure that the point of hook-up is functioning correctly and no faults
are present.
➤ In case of power failure, disconnect the power supply to prevent the
Fluid Heater from switching on independently.
