REFRIGERATOR COMPONENTS
Control panel: The chamber temperature and other alarms/functions can be set using the keys on
the control panel. The operational status can be checked on the temperature display and indicator [page
14].
Door switch: This switch detects the door open/close status. The LED lamp on the control panel
blinks red when the door is open.
Air intake vent: This is an air intake vent for circulating the air in the chamber. Do not block this vent.
Blocking this vent may cause unstable chamber temperature.
Glass door: Sliding type. The recessed portion on the rail enables the self-closing of the door. The
glass is pair construction.
The condensation may be found on the door frame and on the glass surface depending on the installation
environment. This is not a malfunction. This is not unusual.
The condensation on the door is dropped on the rail and exhausted to the evaporating tray.
Drawer (right side of MPR-S500RH): The allowable load is 20 kg per drawer [page 19].
Note: Never pull out the multiple drawers at a time. It may cause tipping over of the unit.
Space for temperature recorder: A temperature recorder (optional) can be mounted here so that the
chamber temperature can be recorded automatically [page 61].
Contact our sales representative or agent to arrange the installation.
Leveling foot (front): These are screw bolts used to install and fix the unit. Adjust the height of the
levelling feet by turning the screw bolts until the two front casters are away from the floor [page 16].
Keyhole: Push and turn the key clockwise through 90 degree to securely lock the door.
Shelf: The location is selectable. Set the shelves horizontally and securely. The allowable load is 20
kg (MPR-S500RH) and 50 kg (MPR-S500H) per shelf.
Items to be stored in the chamber must be placed on the shelves. Do not put stored items directly on the bottom of
the chamber.
Access port: This port is used to pass the sensor or cable of measuring equipment, or the sensor of
a temperature recorder (optional) to the chamber.
Replace the insulation and the rubber caps when the access port is not in use. Improper replacement may cause
an increase in chamber temperature or condensation around the access port.
Air exhaust vent: This is an air exhaust vent for circulating the air in the chamber. Do not block this
vent.
Blocking this vent may cause unstable chamber temperature.
Remote alarm terminal (backside): A remote alarm device (separately available) can be connected
to this terminal. The remote alarm relays the alarm to an operator in a remote location if the unit is un
attended [page 51].
Contact our sales representative or agent to arrange the installation
Circuit breaker (backside): Before starting the refrigerator, check the switch is on.(ON=“|”,
OFF=“○”)
The round button under the circuit breaker is a leakage test button. The operation check of the circuit breaker can
be performed by pressing this button. But note the power supply to the unit is disconnected when this button is
pressed.
Space for interface board: An interface board (optional) can be mounted here [page 61].
Contact our sales representative or agent to arrange the installation.
Port for servicing (back, left): This is a access port for servicing. Do not remove the rubber cap.
Switch for power failure alarm: This is a switch for power failure alarm [page 61]. Normally, set the
switch to ON. Turn off the switch when the refrigerator is no use.
This switch is provided with the optional battery kit for power failure alarm.
