Seal the Base
- After the unit is completely installed, apply a bead of caulking around the base of the
fountain to ensure no wind enters through the base of the unit.
NOTE:
Sealing the bottom of the unit from cold air is an important aspect of the unit's thermal
performance.
N.
Drain Plug
– Insert the pre-assembled drain plugs firmly into the drain holes from inside the trough
at each end. Wetting the plug can aid in installation.
O.
Valve Frame and Cover
– Before installing the
valve chamber frame, the weather seal must be
installed on the frame (right). The seal is installed by
removing the paper backing from the adhesive side
and then starting at the midpoint of the frame leg;
attach the seal to the frame. Work your way around
the frame with the seal as close to the inside edge as
possible and then up the other leg to the halfway
point. At this time cut any extra foam seal as needed
then repeat for other side.
The frame can then be attached to the casing and
trough using the T-bolts and nuts provided in parts
bag. The T-Bolts slide into the four T-shaped holes
(shown below) located near the center of each trough
railing. Twisting the base of the T-bolt, once inserted,
helps the bolt sit upright while installing the frame. A
washer should be used on the head of the screw as
well as under the nut. Tighten securely.
