TFT DryAir
First start-up
Preliminary checks
CAUTION! The installation and the first start-up of the unit must be TFT.
CAUTION! The power supply is constantly present in the general switch of the unit. Risk of
electric shock.
For the first start-up, perform the following checks:
1.
Make sure the power switch electrically isolates the dehumidifier and the isolator is in the OFF
position
.
2.
Open the panels of the dryer and make sure there are no foreign objects inside and in the electrical
cabinet.
3.
Ensure that the flow control dampers are fully open and that the pipes are clean and unobstructed
by objects.
4.
Check the filters and check that they are clean
.
5.
Make sure that the fan impellers can move freely
.
6.
Ensure that the fuses are properly sized
.
7.
Electrically connect the dehumidifier to the electricity grid through the general switch and switch
the main switch ON and check for the voltage at the terminal L, N or L1, L2, L3 of the dehumidifier.
8.
Start the dehumidifier for 3-4- sec with the operating mode selector in position MAN. In this time ,
verify the correct rotation of the rotor. Turn off the dehumidifier with the operating mode selector
in 0 and check the direction of rotation of the fan impellers.
9.
Install the panels, ensuring the seals are all in place.
10.
The dehumidifier is ready to be used.
11.
Start the dehumidifier and control the flow rate of the process and reactivation air. Check the flow
rates on their respective sides of the air delivery. If it is requested, adjust the air flow through a
damper installed on the flow of dry and moist air, or act on the adjustment of the frequency
converter.
12.
If it is requested, verify the performance of the dehumidifier by measuring the quality of the dry air
produced on the output of the dehumidifier and compare the values with ones reported on p. 23.
