4. Mark the position of the hole in each clamp on the
equipment pad.
5. Use a masonry drill bit and drill a hole in the cement
with a diameter as determined by the concrete
anchor, at each of the marks on the equipment pad.
The hole should be approximately 1/2-in. deep.
6. Insert a bolt anchor into each of the holes. Be sure
the anchors are set completely into the holes.
7. 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.
8. 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 and Plumbing

The image below shows the standard plumbing layout
with a single UltraTemp
®
image from right to left for the standard plumbing
sequence.
Arrangement of pool system components (other than the
standard plumbing image below), and the location of the
heat pump (above or below the pool water surface) can
affect the operation of the heat pump's water pressure
switch.
The pressure switch can be adjusted to accommodate
this effect if the heat pump water connections are no
more than six (6) feet [1.8 m] below the pool water
surface.
See instructions for pressure switch adjustment on page
6. 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.
Note: Be advised that when pool equipment is located
below the pool surface a leak can result in large-scale
water loss or flooding. Pentair is not responsible for such
water loss or flooding or damage.

Automatic Flow Control Valve

The inlet/outlet header of the heat pump comes equipped
with an internal automatic flow control valve. The
automatic flow control valve maintains the proper flow
through the heat pump at rates up to 120 gpm (456 lpm).
If the filter system flow rate is higher than 120 gpm (456
lpm), install a manual bypass valve, see image below.
Note: Be advised that if your circulation pump is over 2
HP or if the total flow exceeds 120 gpm (456 lpm), you
will have to add an external bypass valve. Excess water
flow will damage the heat exchanger.
