Pressure-type Chlorinator or Brominator
The pressure-type chlorinator or
brominator takes a small amount of water from
the outlet side of the filter, adds chemicals to it
and returns this highly concentrated solution to
the pool. The check valves must be highly re-
sistant to corrosion. Use only a check-valve ei-
ther supplied or recommended by the chlorina-
tor (brominator) manufacturer.
The p-trap should be installed higher than
the top of the chlorinator (brominator) to
prevent migration.

Any automatic distribution system of chemical products, chlorine, bromine or others,
must be installed after the outlet of water from the heat pump. The warranty of the
heat pump will be voided for any installation that is not in accordance with
this rule.
Basic Connection
This connection method is strongly recommended
to enhance the life-span of your pool heat pump.
If you connect the unit this way, you have to pour
chemicals directly into the pool or the spa, as far as pos-
sible from the water supply point.
Do not pour chemicals in the skimmer or at the
bottom of the pool, if you have a drain, because of
the possibility of migration of the chemicals to the
heater.

Chlorinators, Brominators and Other Automatic Systems
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 Maintenance on p.12.)
