Figure 31. Removing Condenser Filter
NOTE
Belt life will be increased if new drive belts are tightened after two or three weeks of operation.
4.7 CONDENSER CLEANING
The condenser requires periodic cleaning. To clean the condenser, refer to the following steps:
A.Lift the condenser filter off the freezer cover panel. Visually inspect the condenser filter for dirt (see Figure 31).
B.If the condenser filter is dirty, vacuum or brush clean, rinse with clean water and allow to dry before replac ing on freezer.
NOTE
If the condenser is not kept clean, loss of refrigeration efficiency will result.
4.8 PREVENTATIVE MAINTENANCE
It is recommended that a preventative maintenance schedule be followed to keep the freezer clean and operating properly. The following steps are suggested as a preventative maintenance guide.
WARNING
Hazardous Voltage and Moving Parts
Never attempt to repair or perform any maintenance on freezer until all main electrical power to freezer has been disconnected. Failure to disconnect electrical power before servicing may result in serious injury or death.
The United States Department of Agriculture and the Food and Drug Administration require that lubricants used in food zones be certified for this use. Use lubricants only in accordance with the manufacturer's instructions.
A.Daily Checks
Check for any unusual noise or condition and repair immediately.
B.Monthly Checks
1.Check drive belts for wear and tighten belts if necessary. (Refer to Section 4.5.)
2.Check the condenser for dirt. (Refer to Section 4.6).
4.9 EXTENDED STORAGE
Refer to the following steps for winterizing the freezer or for storing the freezer over any long period of shutdown time.
A.Clean thoroughly with warm detergent all parts that come in contact with mix. Rinse in clear water and dry all parts. Do not sanitize.
NOTE
Do not let cleaning solution stand in freezer barrel or mix pump during the shutdown period.
B.Remove, disassemble, and clean the front door, auger shaft, and mix pump. Leave disassembled during the shutdown period.
C.Place plastic auger flights in a plastic bag with a moist paper towel. This will prevent flights from becoming brittle if exposed to dry air over an extended period of time (over 30 days).
E.Place the mix pump
F.Disconnect from the source of electrical supply in the building.
4.10 ERROR CODES
The following error condition codes will display on the control panel when the freezer is experiencing a problem. The error condition code directs you to the system location of the malfunction.
ERRORCODE | MALFUNCTION |
01 | Program Board |
02 | High Torque Error |
03 | Extended Run Time Error |
04 | Clean Error |
05 | Freezing Cylinder Sensor |
06 | (not used on F431 models) |
07 | Drive Motor Current |
08 | Cab Sensor |
09 | High Pressure Cutout |
Any error causing condition must be corrected, then the power turned off, and back on before the freezer will return to normal operation.
