STARTUP AND OPERATION

5.1 INITIAL STARTUP

Ensure a suitable supply of compressed air between

4,1 bar (60 psi g) and 16 bar (230 psi g) pressure is

available and check that the dryer cannot be

overﬂowed.

IMPORTANT NOTE

Control air pressure is to be below 10 bars. If the

working pressure is above 10 bars then use a pressure

regulator and set it below 10 bars. (Pressure regulator

is not supplied with the dryer.) Inlet temperature must

be between 4.4°C (40°F) to 49°C (120°F) at all times.

IMPORTANT NOTE

Ensure all valves are opened and closed gradually.

Proceed as follows: (Refer to Figure 3-2)

5.2 WITHOUT THE BY-PASS LINE

Close inlet and outlet valves.

Introduce air to the dryer by opening the inlet valve

slightly, wait for the dryer to fully pressurize then fully open the

valve. Allow dryer to fully pressurise, then

gradually open the outlet valve.

Turn on the ON/OFF switch at the bottom of the dryer. The green

LED on the panel will illuminate and the dryer will start cycling in

10 seconds. The mini- PLC screen shows the operations at that

moment. The dryer is now on stream.

5.3 USING THE BY-PASS LINE

With the inlet and outlet valves closed and the by- pass valve open, introduce air to the

dryer by opening the inlet valve slightly, wait for the dryer to fully pressurize then fully

open the valve.

Allow the dryer to fully pressurise, then open the outlet valve while simultaneously clo-

sing the by-pass valve.

Turn on the ON/OFF switch at the bottom of the dryer.The green led on the panel will illuminate and the

dryer will start cycling in 10 seconds. The mini-PLC screen shows the operations at that moment. The

dryer is now on stream.
