1. GENERAL
1.1 Applications
For faster circulation of water in central heating and air-
conditioning circuits (light commercial).
• For closed circuits.
(circulators should not be used for food-processing
applications).
1.2 Specifications
• Maximum operating pressure
• Isolation class
• International pump protection
• Tension standard
(60 Hz on request).
• Water temperature range
• Maximum ambient temperature
• Water + glycol mixture
(no other liquid without
approval in advance).

(correct the hydraulic performances accordingly).
• DN orifices
• Minimum suction head (m.w.g) versus operating
temperature.

2. SAFETY
Read this instruction carefully before installing and starting
up. Pay special attention to the points concerning the
safety of the equipment as regards the intermediate or final
user.

3. TRANSPORT AND STORAGE
When receiving the material, check that there has been no
damage during the transport. If any defect has been stated,
take the required steps with the carrier within the allowed
time.
If the delivered material is to be installed
CAUTION !
later on, store it in a dry place and protect it
from impacts and any outside influences (humidity, frost,
etc...).
Handle the pump carefully so as not to alter the geometry
and the alignment of the hydraulic unit.
Never hang the pump with the electric cable.

4. PRODUCTS AND ACCESSORIES
4.1 The pump description
• SCX (3~) or SXM (1~) : single-head pump.
• DCX (3~) or DXM (1~) : double-head pump with non-return
valve on discharge to allow switching between pumps.
Hydraulic part : with threaded ports, exept with PN 10/16
flanges for DXM 40-25 and 40-45, DCX 40-25 and 40-45.
Flanged models : casing with 3 bosses for wall mounting and
flanges fitted with pressure gauge ports (Ø 1/8").
4.2 Motors
Motor 2 poles with wet rotor, self-lubricating bearings.
All models pumps are equipped with a 3 speed motor.
Anycase, the speed is visualised through a window in the
box cover (See § 5-4 "speed selection" and FIG. 2).
single-phase : 230 V (±10%), 3 speeds manually set by means
of the rotary switch, capacitor in the terminal box
(See FIG. 3).
Three-phase : bi-tension 230/400 V, with direction rotation
green-light, speed choice by a speed selector plug three
400 V (speed selector three-phase 230 V sold as an
additional accessory) (See FIG. 4).
4.3 Motor protection (thermal overload contact)
Single-phase : is equipped with a thermal overload
protection internal.
Three-phase : is equipped with a thermal overload
protection internal.
The double-head models, is also equiped of such a
protection.
4.4 Accessories (optional)
• Blank cover • Unions or PN10/16 round counter-flanges to
weld-on or screw-on • Pressure gauge kit (for flange models)
• Control box for double models (YN1200 box or MGP
module) • Speed selector 3~ 230 V (See FIG. 4b)...
5. INSTALLATION
5.1 Mounting
- Make such the circulator is accessible.
- Install isolating valves beyond the ports to allow removal of
the circulator and all work on it.
- Note the direction of flow indicated by arrows on the
casing (or on the flanges) (See FIG. 2).
- install directly on a horizontal or vertical pipe.
- The motor shaft axis must always be horizontal (See FIG. 1).
Do not insulate the motor casing. If the
CAUTION !
pump casing is insulated, make sure that
the condensates evacuation holes in the motor flange are
not blocked.
If the double pump (DCX or DXM) is installed on a horizontal
pipe, with the motor shaft axis horizontal, it will be necessary
to switch operation between the pumps from time to time to
avoid the formation of air pocket at the high point of the
casing, or else to connect an air bleed device to the port
(orifice to be done only for flange models).
