OPERATING INSTRUCTIONS

1. Operating conditions

Standard construction
- For water circulation in spas, hydromassage bath-
tubs and whirlpools.
- For clean water with a maximum temperature of
60 °C (140 °F). Limit the water at the inlet to the
bathtub to a maximum temperature of 50 °C
(122 °F).
- Maximum water level in the bathtub or spa:
2,000 mm above the pump.
- Maximum permissible hydrostatic pressure and
pump discharge pressure: 2.5 bar (36.2 psi).
- Maximum ambient temperature: 40 °C (104 °F).
Sound pressure: < 70 dB (A).
To isolate the motor from pumped water the
Compact Spa pumps are made with high qua-
lity plastic materials. Correct pipe connection and
necessary precaution during installation along
with use in accordance with the limits specified
will ensure trouble-free operation .
Follow these instructions.

2. Installation

The Compact Spa pumps must be installed
with the rotor axis horizontal and feet downwards
in piping layouts in which the filling and drai-
ning of the pump is obtained through
the pipes, with filling and draining of the
bathtub or spa.
Whirlpool tubs must be constructed so
that the water cannot remain in the
system after the tub has been drained.
To allow for self-draining, mount the pump on a
base positioned at a level equal to or higher than
the bathtub or spa suction port and, to allow for fil-
ling, with the delivery port positioned at a level
lower than that for normal filling (under the over-
flow discharge).
Installation beneath the skirt of a bathtub or spa
which is closed externally with protection panels
must provide at least one slot with a 5-10 mm
aperture (preferably between the panel and the
floor) suitable for air recirculation for ventila-
tion of the motor.
Mount the pump on a base located at least 40
mm (1 1 / 2 inches) above the intended mounting
surface. For outdoor spas or whirlpools, the pump
and electric parts must be installed within an
enclosure for protection from the weather and
flooding and installed on a base located at least
100 mm (4 inches) above the mounting surface.
Make sure installation allows access for servicing
and inspection, disassembly or replacement of
the pump.
Follow standards for safety (some safety
standards are indicated in the section 4).
3. Pipes
Connections of pipes to the pump ports.
Use pipes made of PVC type, plastic material.
The pump ports are designed to allow for direct
cemented joints (fig. 1). The external thread
allows for connection with an optional, remova-
ble union coupling (fig. 2).
Fig. 1 Cemented joint.
Fig. 2 Threaded union coupling.
To join the pipe to the pump or to the union
coupling, use an adhesive or cement suitable
for the ABS material. Follow carefully the
instructions of the product chosen .
