HOW TO INSTALL THE AIR DIFFUSER

1. See picture (top right hand corner) to help you identify the flat spot on the bottom drain.
2. Drill a hole and place the bulkhead fitting in. (It has a gasket inside) Apply silicone to secure it from leaking.
3. Put Teflon tape on the 1/2" PVC Male Adaptor. Add silicone. Screw in to the bulkhead fitting continuously.

....connect the 1/2" PVC pipe all the way to the air pump.
4. Drill a hole on the center of the cover and add a 3/4" fitting.

HOW TO INSTALL THE W. LIM BOTTOM DRAIN ON A PRE-FORMED POND
PRE-DILL:
1. On the Bottom Drain cover, there are 3 screw holes marks. Drill the holes to fit the 1/4" PHIC Flat screws.
2. Turn the cover over. Align the BDR ring on top of the 3 newly-drilled holes (ring should have 16 hole marks
.....facing up) and drill 3 holes through the ring, making sure the new holes do not cut through the 16 hole marks.
PROCESS:

1. Put the ring in the most bottom (deepest) part of the pre-formed pond. Use a marker to draw two circles: one on the
>>the outside edge of the ring and the other on the inside ring.

2. Remove the ring. Drill and cut around the inside circle to make a hole to fit the mouth of the Bottom Drain.

3. Place the ring above the hole of the pond. Insert the three 1/4” PHIC screws facing up from under the ring. Secure
>>with one nut, and put another nut on the screw. You will use the third nut to install the cover later (see #6).

4. Underneath the pond, put the Bottom Drain right under the hole. Bolt the 16 Self Tapping screws from the ring,
>>through the pond onto the Bottom Drain.

5. Use a gasket and/or silicone between the ring and the pond to seal tightly.

6. Before installing the cover, adjust the second nut to leave only a little space (1/2" more or less) this is to prevent the
....smallest fish from getting sucked into the bottom drain. Bolt the cover with the third nut.
