6. INSTALLATION
General items of attention:
- The optimal ambient temperature shall be within +20°C and +25°C (maximum tolerable
+35°C)
- With every freezer a pair of spacers is delivered, which can be mounted at the backside of
the freezer.
- During the cooling, the high temperature (1
e
) stage compressor will operate at first, as well
as the ventilator which cools the condenser. After ± 6 minutes the low temperature (2
e
)
stage will switch on.
- It’s possible that the low temperature stage switches on/off several times before the final
temperature has been reached. After some time (depending on the capacity of the freezer
and on the ambient temperature) the set temperature will be reached.
- The potential free contact, which is situated at the back of the freezer, can be used to signal
an eventual alarm at distance (for example to the technical service).
- We advise to keep the door open as short as possible to avoid freezing and temperature
leaps.
- If the ultrafreezer is kept on stock fo a long while, the battery may be out of power. So,
loading the battery can take some time.
- The RJ connection, at the back of the freezer, can be used to connect the freezer to a local
network (Ethernet).
Water-cooled condenser, see chapter 4:
- Connect the water supply tube to the water connection (4).
- Take care that there is sufficient water pressure available (+/- 4 bar) and that the quality of
water is as clean as possible (it should not be extremely chalky).
- For safety reasons you can choose to arrange a water lock in the water inlet (for example: in
case there will be more than 5 liters flowing through, it will switch off the water supply
automatically, think for example about a laundry machine connection).
- The advisable water temperature is +15°C.
- Connect the water drainage to the return water system(1).
- Open the water drainage and check it for leakages. Remember to check the drainage also
when the freezer is functioning.
- Take care that there are no nods in the water tubes and check that they are mounted
properly.
Water- and air-cooled condenser:
- Connect the power cable to a 220V outlet, fitted with a 16A slow fuse.
- Install the enclosed spacers to the back of the engine room, see page 7.
- LOAD will appear in the display.
- When LOAD is off, switch on the freezer as mentioned in paragraph 7.
