Safety System
Thermostat Independent electronic
circuit; thermal cutoff shuts
the heater OFF to ensure
hose end air remains below
56°C (53°C ± 3°C typical)�
Alarm system Over-temperature (≤56°C,
53°C ± 3°C typical): red
Over-Temp indicator symbol
will flash alternately with
the "Wrench" symbol,
alarm sounds, heater and
blower shut down, operating
indicator lights turn OFF,
and control panel becomes
unresponsive� Remove from
service�
Under-temperature (<3°C
of selected temperature/
setting for 3 minutes):
blue Under-Temp indicator
symbol will flash alternately
with the "Wrench" symbol,
alarm sounds, heater and
blower shut down, operating
indicator lights turn OFF,
and control panel becomes
unresponsive� Remove from
service�
Fault "Wrench" symbol displays
and alarm sounds� Heater and
blower shut down, operating
indicator light turns OFF
and control panel becomes
unresponsive� Service
required�
Overcurrent protection Dual input fused lines� Fuses
are to be accessed and/
or replaced only by service
personnel�

Guidance and manufacturer's declaration – electromagnetic emissions
The model 675 is intended for use in the electromagnetic environment specified below� The customer or the user of the model 675 should
assure that it is used in such an environment�
Emissions test Compliance Electromagnetic environment - guidance
RF emissions, Group 1 The model 675 uses RF energy only for its internal function� Therefore, its RF emissions are very low
CISPR 11 and are not likely to cause any interference in nearby electronic equipment�
RF emissions, Class A NOTE: The EMISSIONS characteristics of this equipment make it suitable for use in industrial areas
CISPR 11 and hospitals (CISPR 11 class A)� If it is used in a residential environment (for which CISPR 11 class
B is normally required) this equipment might not offer adequate protection to radio-frequency
Harmonic Class A
communication services� The user might need to take mitigation measures, such as relocating or
emissions, IEC
re-orienting the equipment�
