8.1.3.2 Starting your ice machine
Check that the starting procedure of your
GENEGLACE is carried out as described in the sec-
tion ‘’ Diagram of operation’’.
Check that the distribution tank is correctly fi lled with
water.
Adjust the back pressure valve to the reference
suction pressure for your GENEGLACE (in the case
of connection to central refrigeration plant).
Adjust the superheater 4 to 6 °K see section ‘’Adjus-
ting the expansion’’.
Check the correct oil carry-over to the compressor
(in the case of refrigerating system with a dedi-
cated
compressor).
After a few minutes of operation, check that ice is
forming over the full height of the drum swept by the
reamer.
If this is not the case, see the section ‘’Faults’’.
8.1.4 Other checks
Check that the ice is stripped correctly.
If after a few minutes of operation the generator
makes a signifi cant noise when the ice is stripped or
the ice has diffi culty in releasing itself, see sections
‘’Faults and Addition of salt’’.
Check that the wipers are performing their function
(no
water
fl owing into the ice store). To adjust the
wipers see section’’ Adjusting the wipers’’.
Check, by simulating the presence of ice while
pressing on the switch, that the ice safety detector is
operational.
If required, adjust the salt dosage. See section
‘’Addition of salt’’.
Important
The high ice safety detector is, as its name indi-
cates, a safety device for the generator and not a
control device. For this reason, it should never be
used for the purpose of controling the quantity of
ice in the bin.
8.1.4.1 Addition of salt
Check that the salt addition system is operating correctly.
8.2 Recommended uses
In the case of an independent refrigerating system, leave
the power supply of the system switched on during periods
of stoppage : the crankase heater must remain live.
In the same case, after a long period without electrical
power, power on at least 3 hours before starting-up.
Avoid short duration run and stop periods. It is preferable
to leave the machine operating for 4 hours rather than
short-cycling it 4 times 1 hour on and 1 hour off.
During prolonged stoppages (more than a week), it is
advisable to run the machine for 1 hour without adding
salt and to drain and dry the base.
Management of a stock of ice :
The basis for calculating the effective volume is : 500 kg
about of freshly fl aked ice for 1m
3
of storage.
To keep the ice fresh, do not keep it for more than 2
days.
The ice storage container must be emptied at least once
a week so that the user has no diffi culty in extracting the
ice. There is also a risk of damage to the GENEGLACE,
by a build-up of ice in the generator.
8.3 Start-up report
A start-up report at the initial start up will :
-
enable you to check the correct operation of your
installation by noting a few key points of operation.
-
Open all right for warrantly.
You will fi nd an initial start up report at the end of this
notice, it has four headings.
-
Points to note : description of the inspection or check
to be carried out.
-
Values : generally a physical quantity to be measured
and entered or a box to be ticked as checked.
-
Where to note : the exact location of the note or check
to be made in relation to the fl uid diagram attached
to the note.
-
How to note : for the purpose of helping you to make
the most accurate note possible by means of a
precise
procedure.
