INSTALLATION
The installation instructions contained in this manual are designed for use by qualified personnel only, trained especially
for installation of this type of heating equipment and related components. Some states require installation and repair by
licensed personnel. If this applies in your state, be sure your contractor possesses the appropriate license.
Anchor Clamp Installation
Installation of the anchor clamps is recommended in all
installations. Installation of the anchor clamps is required
in Florida (see Florida Building Code 301.13).
Anchor clamps hold the heater to the equipment pad in
order to withstand high winds caused during extreme
weather (i.e. hurricanes).
Note: Anchor clamps are included with the heater. They
can be found attached to the wood pallet that the heater
is shipped with.
To install the anchor clamps:
1. Be sure the heater is in its permanent location on the
equipment pad.
2. Place the clamps at the base of the heater in the eight
(8) locations, shown in Figure 5.
Note: Bolts and washers are not included with
the heater. The installer must provide 1/4" x 2-1/4"
stainless steel anchor bolts and the appropriate
size washers to mount the clamp to the concrete
equipment pad. Be sure to check local codes.
3. Fit the hook of each clamp into the slots in the base
panel of the heater.
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 concrete equipment pad.
The hole should be approximately 2-3/4" (7 cm.) deep.
6. Position the anchor clamps so that the holes in the
clamps are over the drilled holes in the equipment pad
and the other end of the clamp is secured inside of the
heater base.
7. Insert an anchor bolt through each clamp into the anchor
and tighten to secure the clamp and heater to the
equipment pad. See Figure 6.
Note: Anchor bolts should be tightened to around
four (4) ft/lbs.

System Layout
The image below shows the standard plumbing layout with
a single UltraTemp ETi™ Hybrid Heater unit. Follow Figure
7 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
heater (above or below the pool water surface) can affect
the operation of the heater's water pressure switch.
The pressure switch can be adjusted to accommodate this
effect if the heater water connections are no more than six
(6) feet [1.82 m] below the pool water surface.
See instructions for pressure switch adjustment on pages
10-11. If the heater is installed outside of this range, an
external water flow switch may need to be installed in the
plumbing upstream of the heater.
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.
