6. Drill a hole in the cement using a masonry drill bit, with a
diameter as determined by the concrete anchor, at each of the
marks on the equipment pad. The hole should be approximately
1½ in. deep.
7. Insert a bolt anchor into each of the holes. Be sure the anchors
are set completely into the holes
8. Position the anchor clamps so that the holes in the clamps are
over the bolt anchors. Be sure that the clamp hooks are over the
lip of the heat pump base, see
Figure 5
.
9. Insert an anchor bolt through each clamp into the anchor and
tighten to secure the clamp and heat pump to the equipment pad.
Water Connections
Plumbing layout
See
Figure 6
, illustrating the standard plumbing layout with a single heat pump unit. Following the diagram
from right to left, the plumbing sequence is as follows:
Pool > Skimmer and Main Drain > Pool Pump > Filter > Heat Pump > Chlorinator > Pool
NOTE:
For normal installations, do not install a shut-off valve or any kind of variable restriction in
the water piping between the heat pump outlet and the pool/spa.
The heat pump must be protected from back-siphoning of water. If there is any chance of back-siphoning,
provide an optional manual bypass valve between the pool and the heat pump outlet. Arrangement of pool
system components other than as illustrated in
Figure 6
and the following diagrams can affect the operation
of the heat pump’s water pressure switch. Location of the heat pump above or below the pool water surface
can also affect operation of the switch. In general, the pressure switch can be adjusted to accommodate
this effect if the heat pump water connections are no more than six (6) feet below the pool water surface or
no more than fifteen (15) feet above it. See instructions for pressure switch adjustment (
page 16
) in the heat
pump start-up section of this manual for more information. If the heat pump is installed outside of this range,
an external pressure switch may need to be installed in the plumbing upstream of the heat pump. Call the
Pentair Water Heat Pump Technical Service department at (800) 831-7133 for details.
Be advised that when pool equipment is located below the pool surface a leak can result in large-scale water
loss or flooding. Pentair cannot be responsible for such water loss or flooding or the damage caused by
either occurrence.
