WARNING
Do not open the junction box when energized.
NOTICE
•
During non-operation the unit must be stored dry.
Relative humidity <60%, temperature >15°C.
•
If applicable connect and switch on the space heater.
•
When dismantled it is advisable to place a desiccant bag
inside the junction box
6.3 Adjusting TSH thermal switch (if present) with auto reset
The TSH is adjusted to 80% of maximum.
If an adjustment is needed, then load the heater with maximum power and the lowest
airflow according to specification.
1. Set the TSH on maximum temperature.
2. Wait until airflow and temperature is constant.
3. Adjust the temperature scale down on the TSH step by step with app 10°C at the time;
wait to see if TSH switches off for 10 min. adjust again 10°C continue this procedure
until TSH cuts off the heater.
4. Adjust the TSH scale up with10°C.
5. Test the heater with full load and switch off airflow. TSH must switch off before maxi-
mum allowed temperature for heater is reached. The mechanical TSHH is nonadjusta-
ble.
6.4 Test procedure for TSH/TSHH thermal cut-off
TSH/TSHH are subject to factory test at JEVI.
In case an additional test of the TSH/TSHH thermal cut-off is required in connection with
the commissioning process, the following procedure is recommended:
1. Insert a temperature sensor close to the TSH/TSHH for control of temperature.
2. Warm up the sensors to the set temperature by using a heat gun.
