IMPORTANT:
When an appliance is found to be not working at all or
not working properly, see that the vaccine
temperature is within the recommended limits.
Do not open the lid unless very essential.
Observe temperature from time to time and if you feel
that temperature may exceed the higher limit before
the appliance is repaired - transfer the vaccines to
other working appliance/refrigerator or cold-box.
For any abnormal sound, smoke, smell etc. in the
appliance disconnect the plug from the wall socket
and notify refrigerator technician.
A) THE APPLIANCE IS NOT
WORKING
1.
Observe the green mains-on indicator light on
right on the front panel.
IF NOT GLOWING
I) Check if wall socket switch is OFF
II) Check if power supply is available at the wall
socket. This can be tested by connecting an
electric lamp or other appliances to the socket.
The lamp should glow or the appliances should
work, if supply is available at the socket.
If not available:
There may be some defect in the power supply circuit
(viz: blow-off fuse, loose connections, faulty switch or
socket, single phasing etc.) which should be rectified
through competent Electrical Maintenance
Technicians.
If power is available at the socket:
III) Check that the plug is inserted properly into the
socket.
IV) Check the plug for loose connection or
dislocation of power supply cable connections -
rectify if required.
V) Remove the plug from socket. Check the
incoming and outgoing cable connections on
the terminal strip in the compressor
compartment (see page 6, actions 2B and 2C)
VI) Even after actions as above, the green lamp is
not glowing - Notify Refrigerator Technician.
B) COMPRESSOR IS WORKING,
BUT CABINET TEMPERATURE
IS HIGHER THAN NORMAL
NOTE:
The cabinet temperature may go little higher than
normal, but should come down after some time
when:
New vaccines are stored
The lid is opened frequently or kept open for
longer duration
Unfrozen ice packs are put in for freezing.
1.
Check if recommended space is left on back and
sides of the appliance for air circulation (see page
7, action 4).
2.
Check if there is too much frost formation in the
liner chamber on the inside walls. If so, defrost (see
page 10 for Defrosting and Cleaning)
3.
Check if the compressor is cut off by the
thermostat before required temperature is attained.
If so, adjust thermostat setting (see page 8, action
2).
4.
If the compressor is observed to be running
continuously but no cooling is attained - this may be
due to leakage of refrigerant gas from the system or
defect in the unit, - Notify Refrigerator Technician.
5.
Check if the compressor tries to start but trips-off
early by the over-load protector. This may be either
due to too low supply voltage or defect in the
compressor or starting relay - put `off' the
appliance till return of normal voltage and try to run
once again. If the defect prevails, - Notify
Refrigerator Technician.
