2. SAFETY
Read this data sheet carefully before installing and starting up. Pay
special attention to the points concerning the safety of the
equipment for the intermediate or end user.
2.1. Symbols used in the manual
Warning
Instructions concerning electricity
Calls attention to a potential risk that might affect
the safety of people.
3. TRANSPORT AND STORAGE
When taking delivery of the equipment, check that it has not been
damaged in transit. If anything is found wrong, take the necessary
steps with the carrier within the allowed time.
If the equipment delivered is to be installed at a later time,
store it in a dry place and protect it from impacts and
outside influences (moisture, frost, etc.).
When handling the single-phase circulator, do not use the capacitor
housings for lifting.

5. INSTALLATION
5.1. Mounting (see FIG. 1)
- Make sure that the circulator is accessible.
- Install directly on a horizontal or vertical pipe.
-
The motor shaft axis must always be horizontal.
- Note the direction of flow indicated by the arrows on the flanges
(or on the casing).
- Install isolating valves beyond the ports to allow removal of the
circulator and all work on it.
Do not insulate the motor casing. If the pump
casing is insulated, make sure that the
condensates evacuation holes in the motor flange are not blocked.
If the double pump (C2000N) 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 an air pocket at the high point of the casing, or else to
connect an air bleed device to the port (1/8” dia.) provided for the
purpose (
see FIG. 1
).
The terminal box must not be placed in the 6-o’clock
position on an ice-water circuit, for C2000N (see Fig. 1).
Comment:
The three bosses (drilling, if specified on order) on the
casing are to allow wall mounting; this decouples the pump (which
is heavy) from the pipe and avoids crushing the anti-vibration
sleeves (dimensions,
see FIG. 2
).
