1. The fit should be snug but not tight enough to push bumpers off when aerator is installed Install aerator in riser If extension risers are used it is easier to install or remove an aerator using a lift fork that is supplied in distributor s tool kit The lift fork can be screwed onto a piece of 1 threaded pipe supplied by distributor A 5 length should be adequate for most installations The lift fork should be positioned under the aerator lift handle Install Drip Loops Once aerator is installed push cable down below connector an inch or two This forms a drip loop which channels any water running down the cable away from the aerator Rotate Aerator Clockwise Looking down at installed aerator rotate it clockwise until one of the mounting brackets engages anti rotation block in aerator riser This prevents cutting off the air supply by twisting of the air hose and also eliminates electrical problems caused by twisted cables Place 4 Outside Air Hose on hose adapter attached to aerator IMPORTANT Hose must be in place to insure fresh air for optimum treatment and plant performance If one or more risers are used a longer hose is required Remove the air hose from the top of the aerator and cut a piece from a bulk coil sold separately and install it It must be long enough to fit completely on the plastic hose adapter top center of aerator over shaft and go straight up into the center of the vent Be sure hose is2. black and white lead wires iii Connect wire to internal connectors on Female half of electrical connector note color coded terminals designate power neutral and ground iv Connect two halves of connector 7 Install Foam Restrictor and Aspirator Shaft NOTE An aerator lying on its side would rest on the foam restrictor and bend the aspirator shaft or motor shaft For this reason it is necessary to either block up lower end of the aerator or allow it to overhang an object during installation of aspirator shaft a Slide foam restrictor down shaft until it stops at ground step on aspirator shaft Tighten set screw firmly The Allen key should spring but do not tighten it so much that it slips and rounds out the hex socket b Slide aspirator shaft into coupling already attached to aerator motor shaft until foam restrictor stops against coupling Firmly tighten the two set screws closest to foam restrictor The Allen key should spring but do not tighten it so much that it slips and rounds out hex socket c To ease future disassembly many distributors apply a light coating of lubricant petroleum grease to end of motor and aspirator shaft If lubricant is applied do not use too much or allow it to get into the hollow end of the connector or shaft 10 11 12 Fit Brackets If the bumpers on the bottom brackets do not press against all sides of aerator riser remove aerator and spring brackets out until all of them touch the sides
