INDEX

THE ILR

One of the most important links in the cold-chain is Ice Lining Refrigerator (ILR). This is a unit which operates on the principle of vapour compression system, similar to any conventional compressor type refrigerator operating on 1 15 or 230 volts, A.C. mains supply. However, the ILR has top opening door to prevent loss of cold air during door opening.

ICE LINING

The Icelined Refrigerator and Freezer has a icebank inside the cabinet. The ice bank consists of frozen icepacks during its operation. During periods of power failure and load procedures, the ice bank acts as cold storage to protect the vaccines. The ice bank keep the temperature is not above +8°C for 30 hours.

HOLD OVER TIME

In case of power failure this unit is capable to hold the temperature (if all the ice-packs are installed) inside the Refrigeration compartment between 2 and 8°C under following conditions.

Ambient temperature: Minimum hold over:

32°C 30 hours 43°C 20 hours

POWER SUPPLY

The ILR is fitted with heavy duty compressor which requires low starting current and can also operate within a range of voltage variations.

E.g. if the normal operating voltage is 230 volts, 50 Hz., A.C., it can work even when the supply voltage occasionally go as low as 150 volts or as high as 280 volts.

THERMOMETER

To enable to measure the temperature inside the cabinet without opening the lid, a thermometer is provided with its dial on the front side. This makes monitoring of the vaccine temperature easy.

LOCKING SYSTEM

The ILR is equipped with a lock, operated with a key.

POWER-SUPPLY ARRANGEMENT

For smooth functioning of the ILR it is advisable to connect the same to a 15 Amps power plug socket outlet, wired from the mains with PVC insulated cables of minimum 2.5 mm section of Aluminium (see also page 5 under `Installation'). The larger size of the plug and socket decreases the contact resistance which in turn reduces voltage drop and provides an easy path for the current.

Safety of the personnel and the equipments can not be guaranteed unless the earth wire (green/yellow) of the cord is really earthed. It is advisable to have the earth connections to the socket checked by a competent electrician.

VOLTAGE STABILIZER

Though the ILR is capable of operating within a wide range of voltage variations, for extra safety one separate Automatic Voltage Stabilizer should be used with it.

1. GENERAL INFORMATION

Check the manufacturer's plate, at the back of the ILR and make sure that the ILR has correct voltage for local supply, i.e. 1 15 or 230 volts (fig. 1).

CAUTION Connecting the equipment to wrong supply voltage may damage it.

If you have received equipments of wrong voltage ratings, notify concerned authorities and keep the equipments repacked.

The ILR is to be installed in a well ventilated room, avoiding direct sunshine or any other source of heat. Power supply socket (15 amps socket with switch, fuse and mains indicator lamp is advisable) should be available nearest to the place of installation of the ILR.

Unscrew and remove the screws holding the side cover of the compressor compartment on the right hand side of the ILR and remove carefully the side cover (fig. 2)

EXAMINE the compressor compartment (fig. 3; Check carefully for any damage, dislocation or looseness etc. of the components, specially at locations A, B. C, and D as below and rectify if necessary.

LOCATION A (fig. 4)

Check that all 4 mounting brackets of the compressor are in place and secured.
