It is absolutely not necessary to place flammable or corrosive objects near the heat pump in order to
avoid any risk of damage or accidents.
Never place the pump near fire-fighting nozzles, never keep chemicals that are corrosive or that can
emit acid or alkaline vapors near the pump. If the pump is installed close to the sea, it must be
protected from splashes, winds from offshore or laden with sand. Protective panels arranged at the
minimum recommended distance can be used for this purpo
.
HYDRAULIC CONNECTION CIRCUIT (BY-PASS)
The circulation of the pool water through the heat pump is generally obtained using a pump already
placed at the level of the pool 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 p.
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
they 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
