Chlorinators, Brominators
and Other Automatic Systems
IMPORTANT:
Any automatic distribution system of chemical products, chlorine, bromine or others, must be installed
after the outlet of water from the heat pump.Your heat pump can be damaged, and your warranty voided, if you install
an automatic chemical distribution system before the outlet from the heat pump.
The use of a brominator or a chlorinator tends to lower pH and total alkalinity because of the chemicals in it. If you use
such a product, you must check the quality of the water regularly. (Addition of sodium bicarbonate is recommended to
restore the balance.) (See the section Water Chemistry on p. 9.)
Off-Line Chlorinator or Brominator
The off-line chlorinator or
brominator takes a small amount
of water from the inlet side of the
filter, adds chemicals to it and
returns this highly concentrated
solution to the pool. The check
valve must be highly resistant to
corrosion. Use only a check valve
either supplied or recommended
by the chlorinator (brominator)
manufacturer.
Salt Chlorinator
Salt chlorinators, like in-line chlorinators, must be installed as the last component on the pool return line (the heat pump
must be installed before the chlorinator or the warranty will be void). Salt levels used with salt chlorinators will not harm
titanium heat exchanges.
Whenever using a salt chlorinator, we recommend the use of a check valve so chemicals do not backup into the heat
pump.
Multiple Unit Connection
Multiple installations can be used in parallel or in series.We recommend series installation for a quicker temp rise. For some
larger pools, it may be necessary to install two units in parallel. In multiple installations, double the distances recommended
in the table on page 5. Never place two heat pump models coil against coil, fan against fan or coil against fan as the heat
pumps cannot work properly. Such an installation voids your warranty.

Basic Connection
The heat pump installs
after
the pool pump and filter, but
before
any chlorinator or
chemical feeder. To avoid
chemical damage to the heat
pump, do not pour chemicals
directly into the skimmer or
main drain. Refer to the
maintenance section of this
manual for additional infor-
mation.
