5. PERIODIC OBSERVATIONS / CHECKS / ACTIONS
DAILY
1.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 (see Action 2 on page 8) by steps, allow the appliance 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
2.Clean the exterior of the appliance with a clean dry cloth.
WEEKLY
1.Examine the inner compartment and see if frost formation is more than 1 /4" (6 mm). If so, DEFROST the appliance as described earlier (see page 10).
If it is observed that Defrosting is required to be done each week:
a)Examine the rubber seal on the lid, if it sits properly. Any gap between the cabinet and seal can be checked by placing a visiting card between them. The card should resist being pulled out freely. If the card can be pulled out freely, there exists a gap. Such gap will allow outside air to go in and form frost early. In such cases the lid should be adjusted or the seal should be changed.
b)Restrict and reduce frequency of opening the appliance. Open only when absolutely necessary.
MONTHLY
1.Clean the compressor compartment:
a)Put off the switch, if any, and take out the plug from the wall socket.
b)Take out the plastic grid 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, if they are tight. If not, rectify.
d)Fit back the plastic grid (see page 7, actions 3)
2. Clean the lid seal (see page 11, action 5b).
3.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
