SAFETY PRECAUTIONS
This symbol
words "Danger" or "Warning" indicates the risk level deriving from
failure to observe the prescribed safety precautions:
DANGER
Warns that failure to observe the pre-
risk of
cautions involves a risk of electric
electric shock shock.
DANGER
Warns that failure to observe the pre-
cautions involves a risk of damage to
persons and/or things.
WARNING
Warns that failure to observe the precau-
tions involves the risk of damaging the
pum and/or the plant.
1. GENERAL
These instructions are for correct installation, and optimum
performance of the TIPER and TIPER 2 Pumps, so they
should be read carefully.
These are single-stage centrifugal pumps designed to
operate with compact hydromassage equipment. They are
equipped with a total-emptying system to prevent the dis-
charge of residual liquid in each start-up.
Insulation rated over 3.750 volts between the motor and the
pump.
These units are designed to operate with clean water at a
maximum water temperature of 50° C.
Built of top quality materials, they are subjected to strict
hydraulic and electrical controls and are carefully veri-
fied.
Correct installation is ensured by following these instruc-
tions and those of the wiring diagram; otherwise,
overloads may be produced in the motor. We decline
responsibility for any damage caused by not following
these instructions.
2. INSTALLATION
The pumps should be installed horizontally, securing
them with screws through the holes in the supports to
prevent undesirable noise and vibration.
The suction pipe of the pump should be as short as
possible.
3. PIPE ASSEMBLY
The suction and discharge pipes should have a diameter
equal to or greater than that of the intake tapping of the
pump.
Avoid traps as, in addition to affecting efficiency, they
impede total overall emptying.
The suction and discharge pipes should not rest on the
pump in any case.
Seal all the connectors and unions well. Avoid any dripping
on the motor, which would unfailingly damage it.
together with one of the following
4. ELECTRICAL CONNECTION
The electrical installation should have a multiple
separation system with contacts opening at least
3 mm.
The protection of the system should be based on a
differential switch (I fn = 30 mA). The supply cable
should comply with EEC standards (2) or be of type
H07 RN-F as per VDE 0250.
Single-phase motors have built-in thermal protec-
tion.
To choose the supply cable diameter see Fig. (1).
The diagrams in Fig. (1) simplify correct electrical
connection.
The electric connection must be carried out by
qualified staff following strictly the "EN 60335-2-60"
standard.
Be sure that the earth cable connection is correctly
made.
Be sure that the earth bonding lug between the
bath and the pump is correctly made.
5. CONTROLS PRIOR TO INITIAL START-UP
Verify that the pump shaft turns freely.
Check that the mains voltage and frequency are
according to the name plate.
The hydromassage assembly should be equipped
with a system to prevent the pump from starting
up if a minimum water level is not present. The
pump should wait until the water reaches that
level.
Check the rotating direction of the motor, which
should concur with that indicated on the fan cover.
If the motor does not start up, try to locate the
problem in the table of most common faults and
their possible solutions that is provided further
on.
THE PUMP SHOULD NEVER OPERATE DRY.
6. START-UP
Start electrically the pump only when the suction and dis-
charge pipes are connected to the corresponding inlets
and outlets.
Check that there is no obstacle in the pipes.
Apply voltage to the motor and suitably adjust the jets to
obtain the desired flow.
7. MAINTENANCE
Our pumps for hydromassage facilities do not
require any special maintenance or programming. If
the pump will be idle for a long period of time, it is
recommended to disassemble, clean and store it in
a dry, well-ventilated place.
