6.4. Checking Air and Fluid Pressure

To be sure the system is functioning normally, the following inspection sequence can be run:

· Preparation

  1. Position the unit on a bowling lane (see 'Mounting the Unit onto a Bowling Lane').
  2. Make sure the start indicator  within the start button  burns continuously. (If this is not the case, go to 'TROUBLE CHECKS').
  3. Press the illuminated green start button . The air pump will be switched on and after a few seconds the unit will start moving. The start indicator  will flash.
  4. As soon as the unit starts moving, briefly press the start button  to temporarily halt the conditioning session; the air pump will stay on.

· Check Air Pressure

  1. Check the pressure of the atomizing air: 0.7 - 0.8 bar. This pressure is indicated on the lower pressure gauge in the control compartment.
  2. If necessary, the pressure can be regulated with the pressure regulator next to the pressure gauge: pull the knob, turn it and press it back.
  3. Check the pressure of the external air flow: 0.1 - 0.2 bar. This pressure is indicated on the upper pressure gauge in the control compartment.
  4. If necessary, the pressure can be regulated in the same manner as described at item 2.

· Check Fluid Pressure

  1. Disconnect the (blue) tube connected to the fastener on the upper right hand side of the oil tank. To do this, push the tube into the fastener, hold back the quick-disconnect ring, then pull back the tube out of the fastener.
  2. Connect the supplied pressure gauge to the loose tube end: push the tube end firmly into the fastener of the pressure gauge, then pull back the tube to secure the connection.
  3. Check the gauge reading: 0.2 - 0.35 bar.
  4. If necessary, the fluid pressure can be adjusted with the black precision pressure regulator on the regulator unit which is located in the control compartment at the right hand side: loosen the butterfly nut, turn the regulator shaft, then tighten the butterfly nut. HINT: back-trace the disconected tube to find the precision pressure regulator.
  5. Connect the tube back to the fastener on the tank. As described at item 2, press the tube firmly into the fastener, then pull it back to secure the connection.

· Detect Leaks in Air System

  1. Resume the conditioning session by briefly pressing the flashing start button.
  2. Leave open the control panel and check during the full duration of the conditioning session the pressure of the atomizing air (lower pressure gauge). The pressure should not fall below 0.6 bar. Also, the indicator needle may not (start to) vibrate. If this does happen, the air system should be checked for leakage.
