's instruction to your system is also critical to the heater's life
.
The location of chemical
If an automatic chlorinator or brominates is used, it must be located downstream of the heater.
A trap must be installed between the chlorinator and the heater to prevent chlorine return into the
heat pump. (See below pictures)

(1) Typically, the pool heat pump unit should be installed aside the pools, less than 7.5 meters distance. If it is
installed farther away, the pipeline system will cause greater heat loss. The most of pipeline are installed under
ground ,although the pipeline system has to do thermal insulation ,but tunnels and the soil around will still occur
heat exchange ,for example
,
each 30 meters ( 15 meters to and from the pump=30 meters total)
,
unless the ground
is wet or the water table is high
.
A very rough estimate of heat loss per 30 meters is 0.6KW per hour (2000BTU) for
every 5
℃
surrounding the pipe
,
which translates to about 3% to 5% increase in run time
.
(2) To get the best heat exchange of heat pump unit, it should be matched the normal rate of water flow
recommended in specification sheet.
(3) It is required to increase the discharge pipe to prevent freezing in cold season ,to put “T” fitting and ball valve to
facilitate changing the water in winter or emptying the water out of system to prevent freezing when HP stop
operating at the ambient temperature below zero ,otherwise the unit may be damaged .
(4) It is suggested to install the quick adaptor in front of water in-out connection, which could discharge water easily
to prevent water freezing, and be convenient for maintenance and service.
(5) When unit running ,there will be some condensation water discharged from the bottom ,please hold the
drainage nozzle (accessory ) into the hole and clip well ,and then connect a pipe to drain the condensation water out
.
(6) If water pressure is over 10 KPA ,or water flow rate is more than 11 cubic meters through heat exchanger ,it is
necessary to install the by-pass pipe in water system.
