Dear Customer,
EN
congratulations for choosing a Syncra HF. This pump is ideal for many aquarium and
pond applications including: waterfalls, small streams, powering external filters or
gravity filters, UV sterilizers, professional filtration systems, as well as return pumps
or in sumps for large aquariums. Syncra HF have leading edge technology with a user
friendly design. The pump comes equipped with threaded inlet and outlet which can be connected
to different standard fittings and accessories available on the market.
IMPORTANT SAFETY INSTRUCTIONS
Syncra HF is made in conformity with the national and international security laws. Please read
carefully and save the following instructions to use in the best way your Syncra HF.
1) Always isolate the pump from the mains electricity before installing or carrying out any
maintenance. Power to the pump must be supplied through a Residual Current Device (RCD)
with a rated residual operating current not exceeding 30mA
2) The pump can work "Wet & Dry", in or out of water.
3) Before connecting the pump to the electricity supply, check there are any damages on cord
or plug.
4) The pump has a type Z cable link. The cable and the plug cannot be substituted or repaired; in
case of damage of them replace the entire pump.
5) ATTENTION: do not operate any appliance if it has a damaged cord or plug, if it is malfunctioning,
or if it has been dropped or damaged in any way.
6) The pump must not be used without water otherwise non reparaible damage may accure
to the motor.
7) The pump can be used in liquids or in environment with a temperature not higher than 35° C
/ 95° F.
8) Do not use the pump for uses different to those for which it has been projected as, i.e. in
bathroom or similar applications.
9) Avoid to use the pump with corrosive and abrasive liquids.
10) The pump cannot be used by people with handicaps or by children if they are not supervised by
a person responsible for their safety.
11) To avoid that accidental drips wet the plug or the socket, make a loop with the cord under the
socket level (Pic. A)
12) Avoid to take the pump by the cord during the installation or maintenance.
13) The pump can be used only in the above mentioned applications and it is only for internal use.
14) If the pump or the filter is supplied with a cable 10 metres long, or a cable more than 6 feet
long for the American type (USA), these appliances are intended for outdoor use as required by
international standards.
USE AND MAINTENANCE
Syncra HF pumps are designed favoring the almost total dismantling of its components, to
facilitate proper use and maintenance and ensure a long life. Below is the list of the individual
parts and spare parts (Pic. 2):
1 Completely submergible motor body
insulated with bi-component resin
2 Noiseless and wear-proof rotor with hub impeller
3 O-ring + threaded volute 1" Gas (Mod. 10.0),
1½" Gas (Mod. 12.0 - 16.0)
4 Volute tightening screws (4 pcs)
5 Rear pump cover
INSTALLATION
To install the Syncra HF proceed as follows:
- Connect the joint to the pump outtake to which you can Connect the hose with the appropriate
diameter.
- Place the pump in an area of the pond, easily accessible for the maintenance operations.
- The pump can work horizontally and vertically.
- If the pump is used sumersed and not in line, it must be always fully submersed (Pic. 3).
- Unwind the supply cable where it can be safe from any kind of damage.
6 Pre-filter
7 O-ring + stepped joint D25 mm and
D30 mm with female thread 1" GAS mod. 10.0
8 O-ring + joint D38 mm
with female thread 1½" GAS mod. 12.0 - 16.0
9 Mounting base ( Pond version)
10 Antivibration rubbers ( Aquatic version)
- Connect the plug to a power supply socket with the same voltage as the voltage indicated on
the technical data label.
IN LINE APPLICATIONS
It is recommended to place the pump in spaces where there is a proper ventilation and the pump is
not directly exposed to heat sources.
Place the pump so as to prevent too long idraulic pipings, which would reduce its performance.
Do not position the pump above the water level because it is not self-priming and the risk of the pump
to run dry, or of invisible air bubbles creating a vacum area is very high. Damages which are caused
by the pump running dry are excluded from warranty. To maximize the pump's efficiency, choose a
straight inlet tube to be connected to bows or elbows (Pic. 4).
We suggest to use Inlet and outlet tubes with diameter egual or bigger than the diameter of the
treathed pipe included (Pic. 5).
Do not use the pump leaving the outlet totally closed. A minimum water flow is necessary to keep
the inner motor refrigerated and not running dry (Pic. 6).
MAINTENANCE
Syncra HF needs simple but necessary periodical maintenance for its correct and safe operation.
Before starting first unplug the device from the socket and strictly comply with the safety instructions
and the following procedure:
Remove the entire pump from the pond or from the tank
Disconnect the base (9). Pond Version
Disconnect the pre-filter (6) gently pressing on the flaps on the sides, separate the volute (3) from
the pump (1) removing the screws (4), rinse everything with fresh water.
Remove the entire rotor (2) and rinse it with fresh water, using soap or vinegar and a soft toothbrush
to remove possible calcifications.
Check and clean the rotor housing in the motor body (1), the recirculation system and the lower
bushing with fresh water.
Perform the mounting operation as follows:
Insert the O-ring (a) in the housing inside the pump's body (1).
Insert the O-ring (b) in the housing on the external holed disc of the rotor (2).
Insert the rotor (2) in the pump's body housing (1) checking that the O-ring (2) is correctly
positioned in the housing of the pump body (1) to allow the correct centering of the rotor.
Insert the O-ring (c) in the external housing of the body (1).
Assembly the volute (3) to the body (1) pushing it in place and tighten the screws (4).
Assembly the pre-filter (6).
Assembly the base (9), put the pump in its original position and connect it to the power supply.
IMPORTANT: The pump is equipped with a thermal device and an electronic motor protection. In
case of malfunction which causes the locking of the rotor (due to excessive dirt or other) or operating
without water, the pump, after 20 attempts, it stops automatically. In this case you must unplug the
pump, check the water level and if the rotor is dirty. After maitenance operations, as per the above
instructions, you can plug the pump on to restart it. It may take up to a 'time If the thermal device has
switched on.
ATTENTION: do not underestimate the power of the magnet. If you slightly loose the grip and the
axis hits the rear bearing, the risk to damage the bearing is very high. A damage axis and bearing
causes high reparation costs.
SPECIAL MAINTENANCE AND REPLACING GROUP ROTOR
Remove the complete rotor (2 - Pic. I) from the pumps' body. Insert the hook inside the rotor's house
(Pic. II), snap the ceramic bearing located in the end side of the internal pump's body (Pic. III) and
pull out using a little strenght.
Rinse with fresh water and vinegar the internal sides of the pump and locate the new ceramic bearing
at the beginning of the rotor's house. (Pic. IV). Insert the O-ring (a) in the housing inside the pump's
body (1). Insert the O-ring (b) in the housing on the external holed disc of the rotor (2). Position the
rotor close to the ceramic bearing and push both inside the rotor's house (Pic. V).
Insert the O-ring (c) in the external housing of the pump's body (Pic. VI).
Assemble the volute (3) to the pumps' body (1) tightening the 4 screws.
Assemble the pre-filter (6).
