The condenser and condenser filter require periodic cleaning.
To clean, refer to the following procedures.
WARNING
DISCONNECT FREEZER FROM ELECTRICAL
SUPPLY SOURCE BEFORE SERVICING.
1. Remove the Phillips head screw from the bottom of the
right side panel, and then slide the panels down and
out.
2. To remove the condenser filter, grasp the top and pull
off. Visually inspect for dirt. If the filter is dirty, shake or
brush excess dirt off the filter and wash in warm, soapy
water. Once the filter is clean rinse thoroughly in warm,
clear water and shake dry, taking care not to damage
the filter in any way.
3. Visually inspect the condenser for dirt by shining a light
through the coil from the back (inside) of the condenser
(Figure 28).
Figure 27. Condenser and Filter
4. If the condenser is dirty, place a wet towel over the front
(outside) of the condenser.
5. Using compressed air or a CO2 tank, blow out the dirt
from the back (inside) of the condenser. Most of the dirt
will cling to the wet towel.
NOTE
This procedure will result in a very loud noise.
6. An alternative method of cleaning the condenser is to
use a condenser brush and vacuum.
NOTE
If the condenser is not kept clean, loss of refrigera-
tion efficiency will result; causing extended run time
or soft product consistency.
Water-cooled condensers need an unrestricted supply of
cold, clean water.
3.14 EXTENDED STORAGE
Refer to the following steps for storage of the freezer over
any long period of shutdown time:
A. Turn the CLEAN-OFF-ON switch to the OFF posi-
tion.
B. Disconnect (unplug) from the electrical supply
source.
C. Clean thoroughly with a warm water detergent all
parts that come in contact with the mix. Rinse in
clear water and dry all parts. Do not sanitize.
NOTE
Do not let the cleaning solution stand in the
hopper or in the freezer barrel during the shut-
down period.
D. Remove, disassemble and clean the front door, mix
inlet regulator and auger parts. Place the auger
flights in a plastic bag with a moist paper towel to
prevent them from becoming brittle.
E. On water cooled freezers, shut off and disconnect
water supply at rear of freezer; run compressor for
2-3 minutes to open water valve, and blow out all
water first through inlet then outlet line, using air or
carbon dioxide.
