Operating Instructions WBL-118 Refrigerated bath and circulator
5
Pull the temperature of the heat transfer liquid as close as possible to the ambient
before attempting to shut down the equipment, except when operations as such are
prohibited for the specimen or the application system! Warning, Hazards of burn and
possible electric shock resultant from unattended hot temperature or condensing and
degraded dielectric strength!
The minimum distance away from the ventilating holes at the back or sides of the
equipment to the wall, furniture or other installations shall be 300mm! The inlets of
fresh air and outlets of exhausting air of the immersion controller shall be kept clear
of any obstacles, so that no close-loop of the air circulating may develop.
Keep the equipment away from hot-air emitting source, direct sunshine, strong
magnetic field and electric sparks!
Neither contamination of high concentration dust or corrosive gas, nor strong airflow
surrounds!
Voltage, frequency and current for power supply must meet the requirements as
designated on the nameplate! Use power socket matching the power plug of the
equipment. Hot line
（
L
）
and neutral line
（
N
）
for single phase equipment must not be
reversed!
For possible wet location conditions, where cycle of evaporating and condensing,
overflowing or spillage may occur and for protection against hazard of possible
electric shock, use power socket with appropriate IP protection and additional
residual current circuit breaker (RCD) with rated breaking capacity!
Socket for power supply must be equipped with protective ground (PE) to prevent
against hazard of possible electric shock!
Connect the power from behind the equipment. Plug in and remove the cable by
directly holding the plug. No dragging of cable in any part. Protect the cable from
being damaged by contacting with the hot surface of the equipment or mouse etc!
Caution, Hazard of overflowing or low level!
Never attempt to initiate the equipment if no heat transfer liquid is filled or filling
volume is lower than the minimum level as specified; Never move the equipment if
the bath tank is fully filled with the heat transfer liquid; The liquid level may change
with the heating and cooling of the equipment, and with the immersion or removal of
the specimen!
Disconnect the application system from the equipment only after proper draining of
the heat transfer liquid, especially when the application system is charged to
maximum volume by additional filling of the liquid!
