Operating Instructions WBL-118 Refrigerated bath and circulator
9
Do not disassemble or exchange assembly parts and electric circuits by unauthorized
personnel! Hazard of electric shock!
In case of damaged shipment and dent, deformation or distortion of the enclosure,
contact authorized local MRC distributor or MRC personnel.
2.1.2 Installing
Install the equipment on a rigid, nonflammable surface and well-ventilated place. The bench should
be 600~800mm high for ease of operation. Keep enough space between wall and back, sides of
the equipment for better ventilation. If the equipment is installed on an unstable surface or floor,
abnormal noise may be generated.
The voltage, frequency and current of the power supply must be rated at least the same as those
designated on the name plate of the equipment. The switch board is recommended to be on the
back right side of the equipment and equipped with outlet matching the power plug of the
equipment with protective ground (PE).
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!
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

for single phase equipment must not be
reversed!
Socket for power supply must be equipped with protective ground (PE) to prevent
against hazard of possible electric shock.
2.1.3 Connecting to an application system where necessary
The external circulating pipe, including flexible tubing and hose, shall be connected only after the
equipment and application system are well seated and installed. The length and distribution path
shall be as short as possible and be so arranged that no kink and other mechanical stress develops
during normal use which otherwise may result in thermal and/or liquid hazards!
