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
4

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.
1.
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)

3.
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.

LOCATION B (fig. 5)
Check that the incoming electrical connections of the
power supply cord to the terminal strip are tight.
LOCATION C (fig. 6)
Check that the outgoing electrical connections from
the terminal strip are tight.
LOCATION D (fig. 7)
Check that the mounting brackets of the fan are tight
and also that the fan blades are free to rotate.

4.
Refit side cover of the compressor compartment into
position refixing the screws holding the side cover (fig. 8)
5.
INSTALL firmly the ILR on a level
floor, preferably on wooden
blocks or on a wooden platform to
protect it from damp and dirt.
(fig. 5)
Leave sufficient space on all sides
of the ILR, keep it away from the
walls for good circulation of air
around it, see below:
Back and left side should be
minimum 3 cm away from the
walls (fig. 9a)
Hinges can be pushed against the
wall
Right side should be minimum
10 cm away from the wall (fig. 9b)
6.
The ILR has 4 supporting legs. If
the ILR is not in a level and stable
position, adjust this by adding
wooden blocks or similar under
the legs.

1.
Open the lid of the appliance. Unscrew the the lid
ballast container. (fig. 11)
2.
Unscrew the cap of the lid ice accu and fil it with clean
water.
3.
Unscrew the 3 frame screws and remove the plastic
Refrigerator innerliner. (fig. 12)
4.
Remove all 36 ice-packs from the ice bank and the 5
ice-packs in the refrigeration compartment.
5.
Plug in the appliance for test. The green lamp
indicates that the unit is under power. (fig. 13)
6.
Check in the compressor compartment that the
compressor starts and the fan on the left side is running.
7.
Check that the blower in the bottom of the dividing wall
is running. Check by pushing with your fingers to the
flap thermostat, if a free moving to open and close the
cold air channel is granted.
