1.4 Distance from the pool
Normally, the pool heat pump is installed within a 7.5 meter radius of the pool. The greater the distance
from the pool, the greater the heat loss from the piping. Since the piping is buried for the most part,
heat loss is minimal for distances of up to 30 meters (15 meters to and from the pump= 30 meters total),
unless the soil is wet or the water level is high. Heat loss per 30 meters could roughly be estimated at 0.6
kw-hour (2000 BTU) for every 5
temperature difference between the pool water and the soil

surrounding the pipe
which translates to an operation time increase of 3-5

1.5 Installation of the check-valve
Attention- When using automatic chlorine and PH dosage systems, it is of uttermost importance to protect
the heat pump from high concentrations of these chemicals that could corrode the heat exchanger.
Therefore, such systems should add the chemicals in the conduits located DOWNSTREAM of the heat
pump and it is recommended to install a check-valve in order to prevent backflow when there is no water
circulation.
Damage to the heat pump caused by disregarding any of these recommendations will invalidate the warranty.
