Start-Up And Shut Down - Beko DRYPOINT RA 1300-4400 eco Instructions For Installation And Operation Manual

10.3 Start-up and shut down

During short-term shut down (max. two to three days), it is advisable to leave the dryer and the control
panel connected to the supply current circuit. Otherwise, it would be necessary at a restart of the dryer to
wait two hours, until the oil in the compressor has reached the specified operating temperature.
Start-up (see Section 8.1 "Control panel")
 Make sure that the condenser is clean (air-cooled).
 Make sure that the fan filter of electrical panel is clean.
 Ensure that the cooling-water flow and the temperature are in accordance with the provisions (water-cooled).
 The display of electronic controller shows
 Keep pressed the button
 If the temperature shown on the display is sufficiently high, verify that the refrigerating compressor starts within a
few minutes. NOTE! – With low temperatures, the refrigerating compressor will remain OFF.
 Wait for several minutes and then check whether or not the dew point temperature which is indicated on the display
of the DMC50 electronics is correct and whether or not the condensate is discharged at regular intervals.
 Switch on the air compressor.
Shut down (see Section 8.1 "Control panel")
 Ensure that the dew point temperature indicated on the display is within the permissible range.
 Shut down the air compressor.
 Keep pressed the button
Dryer remote control ON/OFF
 See instructions in Section 8.14.11
Note!
A dew point between 0°C and +10°C displayed on the electronic controller is considered to be correct
according to the possible operating conditions (flow rate, air inlet temperature, ambient temperature
etc.).
The electronic controller DMC50 adjusts compressor and fan(s) speed according to thermal load applied to the dryer.
At very low or no load conditions, compressor is switched ON and OFF by the DMC50 to keep the temperature of the
heat exchanger cold, allowing a consistent additional energy saving. The dryer needs to be switched on during the
entire compressed-air usage time, even if the compressed-air compressor works periodically.
Note!
The number of starts/stops by pressing the ON-OFF switch - pos. 1 control panel must be limited to six
per hour.
Irreparable damage can be caused by starting up the device too often.
