4. If the temperature difference exceeds the threshold of tolerance ±5°C, adjust the setting of the
fan of the reactivation air in the control system, acting on the frequency converter or through
the damper. Wait until the temperature display has stabilized after each adjustment.
Control of the reactivation heating coil
Hot water coil.
1. Make sure that the stop valves are closed.
2. Connect the heating coil of reactivation air to the water distribution system.
3. Open the valve for the water supply.
4. De aerate all remaining air from the coil and the piping system.
5. Check that the water flows into the coil, sensing with a hand that the coil and the pipes heat up
evenly.

Steam coil.
1. Check that the stop valves are installed and closed.
2. Connect the preliminary heating coil of the regeneration air to the steam source.
3. Open the valves to supply steam.
4. Read the pressure gauge and check that the pressure of the steam supply is correct.
5. Visually inspect the pipes connections and preliminary heating coil of the regeneration air and
check for leaks.
6. Read the steam temperature on the thermometer and make sure the temperature is correct with
respect to the line pressure.
7. Open the control valve manually, very slowly to test the system of the condensate drain line.
