  1. Locate the sparger manifold and inspect it for damage and/or debris inside the supply fitting (upturned 90° elbow shown in image). If any debris is found, remove it before proceeding. An easy way to remove material from the inside of the tubing is to immerse the manifold in hot tap water until the tubes are filled. Quickly lift the sparger out of the water and pour the water and any trapped debris out through the 90° elbow. This should not be necessary since the unit was thoroughly cleaned prior to shipping.
  1. Glue the air supply riser tube (the longer of the two gray pipes shipped with the etcher) into the upturned elbow.

  1. Working from the top, wash out the tank with hot tap water to remove any debris that might have accumulated during shipping. DO NOT USE A DETERGENT OR CLEANER! You do not need to dry the tank interior before proceeding.
  2. Insert the sparger manifold into the tank as shown. The air supply riser should be on the opposite end of the tank from the float switch. BE VERY CAREFUL not to knock the float switch during this operation!
  1. Push the manifold until it rests evenly on the bottom of the tank with the end up against the wall where the float switch is mounted. Note that there are holes in the sparger cross members that should match up with the heater hole in the end of the tank.

  1. The stainless steel cartridge heater is installed like all other threaded fittings. A liberal bead of liquid vinyl is applied to the female threads of the moulded coupling located on the side of the tank, as well as to the lead threads of the cartridge heater.
  1. The heater should be screwed into the coupling until it is hand tight. While inserting the heater, make certain that the shaft threads into the matching hole in the sparger assembly. Tighten the screw clamp until it is very tight against sides of the tank coupling.
  2. Using a crescent wrench, tighten the cartridge heater one additional full turn.
  3. Allow the liquid vinyl to dry before proceeding (at least 15 minutes)

  1. After the liquid vinyl is dry, the tank is almost ready for filling and leak testing. Before proceeding, make sure that the float on the float switch slides freely and that no liquid vinyl has dripped into the tank. If some of the sealing vinyl has dripped into the tank or onto the sparger, it can be easily peeled away after it has dryed.

  1. Wipe down the cover with a clean cloth wetted with warm tap water to remove any debris or contamination that may have collected.
  2. Set the cover into the flange around the top of the tank. The air supply riser tube should feed through the 3/4" dia. hole in the plate.
