2. Check fixing screws periodically, and if any loose, fix it.

** Remove the plug from power line before cleaning. Use soft dry tissue to clean the bath interior and avoid any splashing or washing!
If any water or other conductive material fall into the equipment containing electric and/or electronic parts and components, disconnect the power immediately. Power on only after water or foreign material is completely evaporated or removed.
4.2 Regular check of the STB**
Regular check of the STB is required for safe operation. Intervals of six months for normal use, or the first time powering up after repairing or standstill for long period, are recommended for regular check of the functionality. Check the STB as follows:

1. Fill the tank with water to level just over the highest point of the heating coil;
2. Set the temperature at 10°C above the ambient and/or the liquid, so that it keeps heating, LED is continuously on;
3. Initiate the temperature control as for normal use, i.e. the pump is circulating (forced convection models only) and heating is in full capacity;
4. Drain the bath so that the heater and the STB are exposed to the air completely. Make sure no liquid spraying out from the circulating return, dripping from the drain device on the bench or floor;
5. The liquid evaporates immediately from hot surface of the heater. Keep running dry for a couple of seconds until the Stb warning is displayed. Caution, Never run dry for more than 90s!
6. Close the drain device, and fill the tank with water. The STB resets automatically once temperature resumes to below designated limit value.

Caution, Risk of burn hazard and liquid spillage!
Do not touch hot surface of the heater! Keep away from evaporating hot steam! Use protective gloves or glasses if necessary!
Never run dry for more than 90s! Overheating of the coil may damage the heater or degrade its insulation strength!
**** The first time powering up after repairing or standstill for long period, or at 6 months intervals under normal use, check the functionality of the safety temperature limiter (STB)!

4.3 Checking and replacing the fuse
With the mains plug connected and power switch in “on” position and if no LED and digits display, check the fuse first. If any doubt that checking and replacing fuse is necessary, use a fuse with the same size and capacity as rated and do as follows:

1. Make sure the mains plug has been removed;
2. Loosen the screws for the bottom cover and remove the bottom cover. Check or replace the fuse (81) as shown in Fig 5;
3. Replace the cover and fasten the screws.

Do not disassemble or exchange assembly parts and electric circuits! Hazard of possible electric shock!
Except for replacing the fuse, there is no other part necessary for customer to disassemble or repair. If repairing is desired, contact with authorized engineer.
Always remove the mains plug from the power socket when performing checking or replacing the fuse, and never use any fuse different from the original one. Secure the fuse once checked or replaced. For servicing or maintenance, call authorized service engineer.
4.4 Clear error, warning and alarm
When the equipment displays Er01 or Er02, check the connections of the Pt100 where necessary. Er01 and Er02 are indications for short-circuit and open- circuit of the temperature sensor PT100.
For inspection, remove the screws for the bottom cover as for checking and replacing of the fuse (Fig 5). Check the wire connecting terminals of the PCBA for the temperature sensor (82), and make sure no short-circuit or open- circuit occurs (loose connection, for example). If necessary, a multimeter may be used for the resistance of the Pt100. The value of the sensor is 100Ω@0°C and +0.385Ω/°C. At 26°C ambient, the resistance of the sensor is about 110Ω.
In most cases, loose wiring and terminating rather than open-circuit of the Pt100 sensor could trigger an error and alarm. Once fixed, those alarms will disappear when switching on the power again. If alarm still exists with Pt100 checked or replaced, and for servicing or maintenance, call authorized service engineer.
When the equipment displays Stb, try first to pull down the temperature of the heater or the heat transfer liquid and find the cause of the over temperature. The STB resets automatically once temperature resumes to below designated limit value. Reboot the controller by powering off and on again, press (Fig 4-60) and , the normal operation of the temperature control will resume. If warning still exists with STB checked or reset, and for servicing or maintenance, call authorized service engineer.
When the equipment displays alarm ourh, cut off power and deal with the equipment after bath temperature goes down close to ambient, then turn on power again. If alarm still exists with Pt100 checked or replaced, and for servicing or maintenance, call authorized service engineer.
When the equipment displays SPuP, forced convection models only, the equipment can’t work normally, cut off power, find the cause of the over temperature. Reboot the controller again, if the equipment displays SPuP again, press (Fig 4-60) and ,the normal operation of the temperature control will resume. If warning still exists, and for servicing or maintenance, call authorized service engineer.
