III. Installation Instructions
WARNING: Only a professional is allowed to install the heat pump. Unqualified users cannot
install by themselves, otherwise the heat pump might be damaged and the user's safety
will be risked.This section is provided for information purposes only and must be checked
and adapted if necessary, according to actual installation conditions.
1. Pre-Requirements
Equipment needed for installation of heat pump:
● Suitable power supply cable for unit’s power.
● A by-pass kit and an assembly of PVC tube, stripper, PVC adhesive and sandpaper.
● A set of wall plugs and an expansion screw.
● We recommend using a flexible PVC pipe in order to reduce transmission of vibration.
● Suitable fastening studs may be used to raise the unit.
2. Location and pipe connection
IMPORTANT: The inverter pool heat pump should be installed in a good ventilation place.
1) The frame must be fixed by bolts (M10) to a concrete base or brackets. The
concrete base must be solid and fastened; the bracket must be strong enough and
antirust treated;
2) Please don’t stack substances that will block air flow near inlet or outlet area, make sure
there is no barrier within 50cm behind the main machine, or the efficiency of the heater will
be reduced or the machine may break;
3) The machine needs an appended pump (not included with the heat pump).
For the recommended pump specification-flux: refer to Technical Parameter,
Max. Lift ≥10m;
4) When the machine is running, there will be condensation water discharged from the
bottom, please pay attention to it. Please hold the drainage nozzle (accessory) into the
hole and clip it well, and then connect a pipe to drain the condensation water out.
Do not place anything within at least 1m in front of the heat pump. Leave at least 50cm of empty space around the sides and
rear of the heat pump. Do not put anything on or in front of the heat pump!

ATECPOOL SIROCCO HEAT PUMP > User Manual

The inlet and outlet water unions can’t stand the weight of soft pipes. The heat pump
must be connected with hard pipes!
3. Installation Layout
The heat pump is connected to a filtration circuit with a by-pass valve. The by-pass valve
should be half-opened (throttled), while all the other valves should be completely opened. It
is suggested that the by-pass valve only be opened half way to avoid excessive pressure
on the heat pump.
It is imperative that the by-pass is placed after the water pump and filtration. The by-pass
path usually consists of 3 valves. That makes it possible to adjust water flow which passes
through the heat pump and isolates the heat pump completely from any maintenance
without affecting flow of filtration cycle. The filter must be cleaned regularly to ensure that
the water in the system is clean and avoids blocking the filter. It is necessary that the
drainage valve is fixed on the lower water pipe. If the unit is not running during winter time,
please disconnect the power supply and let water drain out from the unit through the
drainage valve. If the ambient temperature of the running unit is below 0℃, please keep
the water pump running.

WARNING: Power supply of heat pump must be disconnected before any operation.
➢Please comply with the following instruction to connect the heat pump.
➢Step 1: Detach electrical side panel by a screwdriver to access the electrical
terminal block.
➢Step 2: Insert cable into heat pump unit port.
➢Step 3: Connect power supply cable to terminal block according to the diagram below.
4.1 Wiring:
a. Connect to appropriate power supply; the voltage should comply with the rated
voltage of the products.
b. Earth the machine well.
c. Wiring must be handled by a professional technician according to the circuit diagram.
d. Set leakage protector according to the local code for wiring (leakage operating current ≤ 30mA).
e. The layout of power cable and signal cable should be orderly and not affecting each other.
