Build Rev 2

System enclosure, cooling system and pump intake filter

Changes to the enclosure modifications in Rev2 include the following:

  • No cutouts in the face of the enclosure for the prototype digital relay timers.
  • Cutouts for new control panel are in the lid of the box. Panel is flush mounted to the top surface of the box. Lid liner requires cutouts as well.
  • Power to the solenoids is 24V . Solenoid plugs are mounted below left enclosure clamp; Photos are provided.
  • 110VAC supply to the power module is made through a flush mount plug. An extension cord is now provided. In the prototype, this same plug was used as a 12V DC output to the solenoid valves. We are no longer doing that from Rev2 forward.
  • Toggle bolts and power supply rail mount system used in the prototype no longer needed. New power module is a drop-in unit with aluminum back plane. Four bolts fasten it to the floor of the enclosure. Sandwich back plane between jam nuts to elevate it off of the sound damping mat. Use aluminum back plane specified in the new parts list as a drill template. Shock mount rubber backing recommended beneath back plane.
