1. General

The purpose of this manual is to provide the necessary information for the installation, use and mainte-
nance of the FC series pumps.
Instructions for disassembly and assembly are also provided, together with a comprehensive trou-
bleshooting chart.

2. Preliminary inspection

After unpacking the pump make sure that no damage has occurred during shipping.
Should the pump be damaged, please inform our agent within 10 days from the delivery date.

3. Applications

FC series pumps are designed to handle liquids which are not chemically or mechanically aggressive, at
temperatures from -20°C to +130°C.
They can be used in many different applications both in the civil and industrial sector:
• Water supply.
• Sprinklers and irrigation systems.
• Heating.
• Air conditioning.
• Transfer of clean non-aggressive liquids.

4. Working limits

Maximum working pressure: 12 bar
Temperature of pumped liquid: -20°C to +130°C
Maximum ambient temperature: 40°C
Maximum number of start-up per hour: 20 (at regular intervals) up to 5,5 kW
Admissible voltage fluctuations: ±5%.

DANGER

5. Installation

DANGER
The FC electric pumps can be installed either in the horizontal or vertical position. However, avoid instal-
lation with the motor underneath to prevent water infiltration into the motor and bearings.
Provide a gate valve upstream and downstream from the pump, and leave a 5 cm clearance between the
fan cover and any large obstacle to ensure free circulation of the motor cooling air. Bleed the pump th-
rough the bleed valve. Do not install the pump at the lowest point in the system to avoid accumulation of
deposits. Fill the system completely and bleed it properly.
N.B. Twin pumps: bleed both pumps through the bleed valve on the pump body. If necessary, repeat
the operation several times.

The pump is not suitable for handling:
– liquids containing abrasives
– liquids with solid and fibrous substances
– infiammable and explosive liquids.
Handling
The product must be handled with care using suitable hoisting equipment.
Impacts can cause damage without any visible external signs. Hoist un-
packed products securely using a sling.
Ground the pump before making any other connection. The installation
technician must make sure that the grounding of the power supply system
complies with local safety regulations. Install a motor overload and
undervoltage protection upstream.
