DO NOT place the unit to shrubs which can block air inlet. These locations deny
the unit of a continuous source of fresh air which reduces it efficiency and may
prevent adequate heat
delivery.
b.
How Close To Your Pool?
Normally, the pool heat pump is installed within 7.5 metres of the pool. The longer the
distance from the pool, the greater the heat loss from the piping. For the most part ,the piping
is buried. Therefore, the heat loss is minimal for runs of up to15 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 0.6 kW-hour,(2000BTU) for every 5 difference in
temperature between the pool water and the ground surrounding the pipe, which translates to
about 3% to 5% increase in run time.
c.
Swimming pool Heat pumps Plumbing
The Swimming Pool Heat Pumps exclusive rated flow titanium heat exchanger requires no
special plumbing arrangements except bypass(please set the flow rate according to the
nameplate). The water pressure drop is less than 10kPa at max. Flow rate. Since there is no
residual heat or flame Temperatures, The unit does not need copper heat sink piping. PVC pipe
can be run straight into the unit. Location: Connect the unit in the pool pump discharge (return)
line downstream of all filter and pool pumps, and upstream of any chlorinators, ozonators or
chemical pumps. Standard model have slip glue fittings which accept 32mm or 50 mm PVC pipe
for connection to the pool or spa filtration piping. By using a 50 NB to 40NB you can plumb 40NB.
Give serious consideration to adding a quick coupler fitting at the unit inlet and outlet to allow
easy draining of unit for winterizing and to provide easier access should servicing be required.
