DAILY

Take temperature readings from the thermometers

and note down the temperature and the time of

reading.

Keep the temperature records systematically. It is

suggested that minimum 2 readings should be taken

(in the morning and afternoon) preferably at the same

hours of each day.

If the temperature is observed to be below or above

the required range, adjust the thermostat by steps,

allow the ILR to run for about one hour under

observation. If required, adjust the thermostat further

until the required temperature range is obtained.

To make the inside colder, the thermostat knob is to

be turned clockwise to a higher setting.

To make the inside warmer, the thermostat knob is to

be turned anti-clockwise to a lower setting.

Check if the inner blower is running (by feeling the air

flow with your hand).

WEEKLY

Check if ice formation has started around the

evaporator and the ice bank. Prepare for defrosting.

Check if the gasket if not broken and if it seals tight

against the frame.

Check if the ballast container in the lid is not frozen.

MONTHLY

Clean the compressor compartment:

a) Put off the switch, if any, and take out the plug

from the wall socket.

b) Take out the side-cover of the compressor

compartment (see page 5, actions 1 ). Clean the

interior of the compressor compartment with a

soft brush.

c) Check the mounting brackets of compressor and

the bolts of the fan, if they are tight. If not, rectify.

d) Fit back the side cover (see page 8, actions 4)

Clean the lid seal.

If possible, put a standard mercury thermometer

inside the cabinet and compare the readings with

those of the dial thermometers and see if they are

correct.

Dial thermometers with incorrect readings may have

to be re-adjusted or replaced, as incorrect readings

may lead to wrong storage temperature and loss of

the potency of the vaccines preserved.
