Assembly Instructions
DRILL HOLES IN RESERVOIR COVER
Drill the 2-1/2" Drain Tube Hole
1. Determine in which corner you want to drill the drain
tube hole. This is the corner directly under the tee
fitting outlet of the drain manifold.
2. Remove cover from reservoir and drill drain hole in
the corner using a 2-1/2" hole saw. Do not drill cover
over reservoir. Debris will damage pump and clog
the filter.
Drill the 1" Supply Tube Hole
1. Using a 1" hole saw, drill a hole for the 3/4" supply
tube from the pump. Drill this hole at the edge of
the porthole opposite the drain tube hole. See X's in
upper-right photo.
2. Carefully remove cover material between porthole
and 1" hole using a hand saw.
Drill the 5/16" Holes for the Air Pump Tubing
1. Take a 5/16" drill bit and drill two holes 2" apart
through cover. See photo below for location.
ATTENTION:
X marks hole locations based on reservoir
design and position.
Drill one 2-1/2" drain tube and one
1" supply tube hole. Always space holes apart as shown.
If 2-1/2" drain hole position is the other corner, drill the 1"
supply tube hole on the opposite side of the porthole.
Move cover off reservoir. Place on support to
drill the 2-1/2" drain hole.
2. Remove all debris from cover and around all holes
to prevent it from dropping into the reservoir when
cover is set in place.
