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.
Water Connections and Plumbing
The image below shows the standard plumbing layout
with a single UltraTemp
®
Heat Pump unit. Follow the
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.
Location of the heat pump above or below the pool water
surface can also affect operation of the switch.
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.
See instructions for pressure switch adjustment on the
next page. 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.
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 con-
crete anchor, at each of the marks on the equip-
ment pad. The hole should be approximately 1½
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.
