heat pump compressor will start.
6. Once the heat pump is running, turn off the filter
pump. The heat pump should turn off immediately.
7. If the heat pump continues to operate when the
filter pump is off, turn the thumb wheel on the
water pressure switch in a clockwise direction
until "NO FLOW" is displayed on the control and
the heat pump shuts down.
8. Check the setting of the water pressure switch by
starting and stopping the filter pump and checking
the control display and operation of the heater
between each flow change.
9. If the water pressure switch cannot be adjusted
to accommodate the conditions listed above,
an external flow switch must be added to the
plumbing system to ensure that the heat pump will
not operate without the proper flow through the
heat exchanger.

Water Chemistry

Proper chemical balances are necessary for
sanitary bathing conditions as well as ensuring your heat
pump's long life. Be sure to keep your chemical and
mineral concentration levels within the values indicated
in Table 3.
note For spas, it is also necessary to perform water
changes in addition to chemical treatment. It is
recommended to change the spa water every
60 days for light usage and every 30 days if
usage is heavy.

Winterizing

Failure to winterize could cause damage to the
heat pump and will void the warranty.
attention
La garantie sera annulée si l'appareil n'est pas
hivernisé convenablement.
preCauCiÓn
La falta de acondicionamiento de la bomba de
calor para el invierno podía causar daños y
anular la garantía.
In areas where freezing temperatures occur, you
should protect your pump, filter, and heat pump from
the elements. Perform the following steps to completely
drain the heat pump (see Figure 16).
1. Turn off the electrical power to the heat pump at
the main breaker panel.
2. Shut off the water supply to the heat pump.
3. Disconnect the water inlet and outlet unions
located on the lower front panel of the heat pump.
The heat exchanger will drain through these water
connections.
