PERFORMANCE CURVES
WORKING CONDITIONS
This pump is designed to handle a neutral liquid without suspended solids with a temperature below
50 °. During operation, the electrical parts of the pump are live. Any intervention on the machine or
equipment can only be carried out after disconnecting them from the mains .

RECOMMENDATIONS AND WARNINGS
The electrical installation must be performed by a qualified professional, in compliance with
the technical and safety regulations in force. This pump is not equipped with a thermal switch,
so it must be installed under a thermal relay and differential protection in compliance with the
technical and safety regulations in force. In order to prevent electric shocks in case of damage
to the electrical wiring, always connect the pump to the system ground . (fig. A)

>75 cm
copper rod / bar placed in depth
fig. A
fixing by welding or screw
Do not connect the pump with damp or wet cables. This pump is not self-priming, so do not run the
pump empty. If this happens by mistake, immediately disconnect the power supply, then wait for
the engine to cool and then fill it with clean water . (fig. B)
fig. B
fig. C
Do not cover the motor body with rags or similar, this could cause a fire. Before proceeding with
the installation, check that the moving parts rotate freely: insert a screwdriver into the recess of the
motor shaft on the side of the fan protection grid and try to rotate the blades (fig. C). If the
movement is difficult to strike gently with a hammer the screwdriver in order to unlock the rotation.
Tampering or modification of the same determine the immediate end of the validity of the
guarantee and can cause serious damage to the machine and to the user .
INSTALLATION
The pump must be installed in a well-ventilated and dry place, protected from bad weather
and exposure to temperatures above 40 ° C. The pump must be installed in compliance with
the EN 60335-2-41 electrical safety standard: any electrical appliance powered at 230 V must
be installed at a minimum distance of 3.5 m from the edge of the pool. The base of the pump
is equipped with holes to be anchored to the ground: fix the pump on a flat and solid surface
by adopting suitable bolts for use to avoid vibrations. The pump must be installed in a
horizontal position in order to allow the correct operation of the bearings. The pipes for
transporting water to and from the pump must be fastened without burdening the connection
points with the pump :

recommends anchoring them to third-party structures using suitable supports. (fig. D) The
connection pipes must not have a diameter smaller than that of the pump outlets and must be
installed perpendicularly and well centered with respect to the pump connection, to prevent the
pump and the pipe from being subjected to improper stress. In case of direct suction via basin
piping, check that the suction piping is perfectly hermetic and completely immersed, at least for
half a meter, in order to avoid the formation of vortices. The use of foot valves with strainer at the
head of the suction pipe is recommended. The diameter of the delivery pipe must be sized in order
to comply with the design flow rate and pressure at the outlet point. The suction pipe must be
installed with a slight inclination of 2% towards the pump, in order to avoid the formation of air
pockets. It is recommended to use a non-return valve between the delivery port and the flow
control valve in order to avoid dangerous water hammer in the event of a sudden stop of the
pump. This recommendation becomes mandatory in the event that the water delivery column is
longer than twenty meters. (fig. E)

ELECTRICAL WIRING
WARNING
The electrical installation must be performed by a qualified professional in compliance with the
technical and safety regulations in force. It is recommended to use an H07 RN-F type
connection cable with a section suitable for the electric consumption of the pump motor and
the number of conductors required for the number of motor phases, plus the grounding cable.
The single-phase motors are equipped with thermo-amperometric protection: they are
connected directly to the power supply network. The three-phase motors must be protected
with an automatic switch (eg. Magnetothermic) calibrated to the plate data of the electric
pump. Install a high sensitivity differential switch (0.03A) as additional protection.
Observe the connection diagram below:

MANTEINANCE MANUAL
AMBRA pag. 6 di 8
www.cpa-piscine.it
Ver01–2021-06-18
The pump can be properly grounded by checking that the electrical connections and clamps
are tight. The pump is able to support a voltage variation equal to ± 10% with respect to the
nameplate data: failure to comply with this condition will result in a reduction in the useful life
of the pump. Check the presence and correct positioning of the gasket in the wiring terminal
box in order to avoid the accidental entry of water into the motor and into the live electrical
parts.
START
Before starting the pump for the first time, check the calibration of the electrical protection
devices of the motor and that the protective devices against electrical and mechanical contacts are
correctly positioned and fixed. Do not use the pool at the time of the first check of the pump
installation.
Perform the following procedure to properly prime the pump before starting the pump :
1. Open the prefilter cover;
2. Fill the pump with clean water through the prefilter until the water comes out through
the intake duct;
3. If the basket moves during these operations, do not forget to place it again inside the
prefilter to prevent coarse-grained particles from infiltrating the pump which could
damage it;
4. Close the prefilter checking the correct coupling of the cover gasket with the pump
body.
WARNING
Dry running causes irreparable damage to the mechanical seal: in the event of an accidental dry
start, immediately disconnect the power supply, then wait for the engine to cool and then fill it with
clean water. Start the pump and check, in the three-phase version, that the direction of rotation is
correct: this should be done clockwise when looking at the pump from the fan side. If this is not
the case, invert the phases in the connection terminal after disconnecting the power supply to the
pump (fig. C). Avoid contact, even accidental, with the moving parts of the machine during its
operation or before its complete stop.
RACOMMENDATIONS
The pump should not be started more than twenty times in an hour so that the motor is not
subjected to excessive thermal stress. Before proceeding with any maintenance operation, check
that the machine is disconnected from the power supply and that the start-up devices are blocked .
MAINTENANCE AND CLEANING
Under normal use conditions the pump does not require maintenance operations, however it could
be useful to clean the hydraulic parts if you notice a loss of pump efficiency. The pump must not be
disassembled by unqualified personnel or by unauthorized technicians.
In any case, all operations must be carried out only after having disconnected the pump from the
electricity mains and after having turned off the ignition devices. .
PERIODIC CHECKS
Check periodically:
-The correct fastening of the mechanical components and the condition of the machine support screws
-The correct position, fastening and condition of the power conductors and insulating components
- The temperature of the machine and the electric motor. In the event of an anomaly, stop the machine
immediately

− The vibrations of the machine. In case of anomaly, stop the machine immediately
− The state of deterioration of the components, periodically replacing those worn by normal use (eg
O-rings, gaskets, bearings)
−In models with pre-filter, regularly clean the basket from the impurities collected to avoid
pressure drops and motor overheating in case of obstruction of the suction mouth .

Risk of freezing: if the pump remains at a temperature of less than or equal to 0 ° C for a long
time, the pump body must be completely emptied through the special drain located below the
pump body in order to prevent breakage and damage to the hydraulic components (fig. G). Then
clean with clean water, dry, remove and store in a dry place. The aforementioned operations are
also recommended for long periods of inactivity in normal temperature conditions. After a long
period of inactivity, repeat all the operations described for the first start-up .
