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 in the drain manifold.
2. Remove the cover from the reservoir and drill the
drain hole in the corner using a 2-1/2" hole saw.
Do not drill cover over the reservoir. Debris will
damage the pump and clog the filter.
Drill the 1" Supply Tube Hole
1. Using a 1" hole saw, drill the 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 the X's in the upper-right photo.
2. Carefully remove the cover material between the
porthole and the 1" hole using a hand saw.
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 port hole.
Move cover off reservoir. Place on support to
drill the 2-1/2" drain hole.

holes to prevent it from dropping into the reservoir
when cover is set in place.
