(9) 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 °C surrounding the pipe, which translates
to about 3% to 5% increase in run time.
(10) To get the best heat exchange of heat pump unit, it should be matched the normal rate of water flow
recommended in specification sheet.
(11) 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 .
(12) 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.
(13) 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.
(14) 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.
