Periodic Maintenance; Daily; Weekly; Monthly - Dometic TCW 3000 SDD Installation, Operation And Maintenance Manual

PERIODIC MAINTENANCE

DAILY

• Take temperature readings and note down the temperature and the time of reading. Keep the
temperature records systematically. It is suggested that minimum 2 readings should be taken (in the
morning and afternoon) preferably at the same hours of each day.

WEEKLY

• Evacuate the condensation water as described before.
• If it is observed that quantity of condensation water is increased :
• Examine the gaskets on the lid, if they sit properly. Any gap between the cabinet and gaskets will
allow outside air to go in and form condensation. In such cases the hinges should be adjusted
or the gaskets should be changed.
• Restrict and reduce frequency of opening the TCW3000SDD. Open only when absolutely
necessary.

MONTHLY

• Clean the unit from any dust :
• Switch off the TCW3000SDD and disconnect it from power supply.
• Clean the condenser on the back side of the unit with a soft brush or a vacuum cleaner.
• Clean the lid seal.

TROUBLE SHOOTING

IMPORTANT :
If a TCW3000SDD is found to be not working at all or not working properly see that the vaccine
temperature is within the recommended limits. Do not open the lid unless very essential.
For any abnormal sound, smoke, smell etc. in the TCW3000SDD disconnect from the power supply
and notify refrigerator technician.
The electronic displays an error message :
F1/ F2 : Probe failure. The unit will continue to work in "ON/OFF-mode" to keep the temperature in the
desired range - notify Refrigerator Technician.
E1 : Voltage protection cut-out. The voltage is outside the cut-out setting - check power supply.
E3 : Compressor start error. The compressor cannot start. Keep the unit switched on. This problem
might occur if the solar generator doesn't deliver enough power (cloudy day, shadow on solar
panels, bad positioning of solar panels etc.). Check the actuals situation of the panels, and if the
problem persists after necessary corrections, notify Refrigerator Technician.
E4 : Minimum compressor speed error. Keep the unit switched on. This problem might occur if the
solar generator doesn't deliver enough power (cloudy day, shadow on solar panels, bad
positioning of solar panels etc.). Check the actuals situation of the panels, and if the problem
persists after necessary corrections, notify Refrigerator Technician.
E5 : Thermal cut-out of electronic unit. The ambient temperature is too high, the electronic unit will
run too hot. Switch the unit off. If after one hour the problem still persists, notify Refrigerator
Technician.
HIGH :
The measured temperature is high than +40°C.
LOW :
The measured temperature is lower than -40°C.
