HYDRAULIC CONNECTION CIRCUIT (BY-PASS)
La circolazione dell’acqua della piscina attraverso la pompa di calore è generalmente ottenuta
using a pump already placed at the level of the pool's filtration circuit (in order to avoid the
attachment of an additional pump).
For this reason, it is advisable to design a branch circuit from the filtration circuit and equip it
with three valves:
▪
An adjustable opening valve, positioned between the delivery and return connections: this allows you
to adjust the ratio between the water flow that passes through the heat pump and the water flow that
does not pass through it, so to obtain the debt incurred through the heat pump (compare the table).
▪
A valve positioned near the pump, on the water inlet pipe.
▪
A valve positioned near the pump, on the water outlet pipe.
These last two valves are usually always in the open position, they must be closed only when
it is necessary to intervene on the pump circuit or to disassemble it.
The by-pass connections must be strictly located downstream of the filter to minimize greasing
of the exchanger, and upstream of any injection of chemical products for disinfestation and pH
regulation (provide a space of 1.5 meters of pipes such as minimum) to minimize the risk of
corrosion of the exchanger.
The injection of chemical products must be strictly subject to filtration. Make sure that the
installation cannot cause accidental siphoning of the chemical product tanks since the filtration
does not work.
Be very careful not to introduce impurities (pebbles, earth ...) into the pipes. These would risk
clogging the exchanger during start-up.
The heat pump is equipped on one of its sides with two union joints for the entry and exit of
the pool water. The water inlet and outlet pipes are to be glued on these joints. Allow to dry
thoroughly before starting the water circulation circuit.
Physico-chemical parameters of the pool water:
the pool water treatment chemicals currently on the market are compatible with the materials used
for the construction of the heat pump, provided that the physico-chemical characteristics of the
water comply with the following recommendations:
•
pH between 7 and 7.4
•
hydrometric title (TH) below 20 ° C
•
Cyanuric acid content (stabilizer) below 80 ppm
•
Free chlorine concentration from 1.0 to 1.5 ppm
•
Concentration of free bromine from 1.0 to 1.5 ppm
