Tank 80% Full
Overfill sensor indicated the recovery cylinder is full. Replace
recovery cylinder.
Input Closed
Cannot zero the displayed pressure because pressure sensor not
open to atmosphere. Open input port.
Output Closed
Cannot zero the displayed pressure because pressure sensor not
open to atmosphere. Open output port.
High Voltage Warning
Voltage was above 250 VAC. Motor stopped. Ensure power network
voltage is between 200 and 250 VAC @ 50 Hz.
Low Voltage Warning
Voltage was below 200 VAC. Motor stopped. Check power network
to ensure voltage is between 200 and 250 VAC @ 50 Hz.
High Pressure Cutoff
Output (cylinder) reached dangerous pressure. Motor stopped.
Ensure all valves after the output port are open. The cylinder may need
to be cooled or replaced to reduce pressure.
Low Pressure Cutoff
Input reached final recovery vacuum. Motor stopped. It’s normal
to see this after RECOVERY or SELF PURGE is complete. Ensure valves
before the input port are open and the knob is not set to CLOSED.
Motor Fault 1
Motor temperature above operating range. Motor stopped.
Extremely high ambient temperature, extended liquid recovery time,
or high cylinder pressure can be the cause. Allow time for the motor to
cool down before resuming, and throttle the RECOVERY (page 21).
Motor Fault 2 (“throttle” shows on display)
Motor current (amps) rose above operating range. Motor stopped.
Extremely high ambient temperature, harsh liquid slugging, extended
recovery time, or high cylinder pressure can be the cause. Throttle
RECOVERY and start the motor. If fault occurs again, throttle even more
and start the motor (page 19).
Motor Fault 3
Motor stopped for unknown reason. If this occurs repeatedly, there
may be something wrong with MR45INT.
Fault 3 (“PLug O F S” shows on display)
80% overfill Sensor not detected. Plug sensor cable into cylinder.
Other Symptoms
MR45INT never reaches 25 cmHg or 50 cmHg.
Check for a leakage before the input port.
Recovery cylinder should be below 3200 kPa for 25 cmHg vacuum.
Recovery cylinder should be below 1600 kPa for 50 cmHg vacuum.
Input port shows frost or signs of leakage.
Ensure the grooved input fitting is hand tight before tightening the
hex nut (page 32).
Recovery is slower than normal.
There could be an input blockage. Check mesh screen filter for
blockage. Ensure knob is set to RECOVER.
Display does not turn on when plugged in.
Ensure power cord and outlet are okay.
Ensure power switch is flipped ON after plugging into power.
Excessive noise during liquid recovery.
MR45INT is experiencing a high load. Rotate the knob of MR45INT
to throttle the refrigerant flow.
Overfill sensor not working correctly.
Check for loose connection. Overfill sensor may be broken. Verify
overfill with scale. If overfill sensor is bad, mark tank for disposal.
