• Observe accident prevention regulations in force.
Position and fastening
The pump can be transported either horizontally or vertically. Make sure that the product is securely
fastened during transportation, and cannot roll or fall over.
Lifting
WARNING:
• Crush hazard. The unit and the components can be heavy. Use proper lifting methods and wear steel-
toed shoes at all times.
• Lift and handle the product carefully, using suitable lifting equipment.
• The product must be securely harnessed for lifting and handling. Use eyebolts or lifting lugs if available.
• Always lift the unit by its lifting handle. Never lift the unit by the motor cable or by the hose.
• Do not attach sling ropes to shaft ends.
Lifting equipment
Lifting equipment is always required when handling the pump. It must fulfill the following requirements:
• The minimum height (contact ITT for information) between the lifting hook and the floor must be
sufficient to lift the pump.
• The lifting equipment must be able to hoist the pump straight up and down, preferably without the
need for resetting the lifting hook.
• The lifting equipment must be securely anchored and in good condition.
• The lifting equipment must support weight of the entire assembly and must only be used by
authorized personnel.
• Two sets of lifting equipment must be used to lift the pump for repair work.

• The lifting equipment must not be oversized.
NOTICE:
Oversized lifting equipment could cause damage if the unit should stick when being lifted.
Storage guidelines
Storage location
The product must be stored in a covered and dry location free from heat, dirt, and vibrations.
Transportation and Storage
8 Flygt 3127 Installation, Operation, and Maintenance Manual

NOTICE:
• Protect the product against humidity, heat sources, and mechanical damage.
• Do not place heavy weights on the packed product.
Freezing precautions
The pump is frost-proof while operating or immersed in liquid, but the impeller/propeller and the shaft
seal may freeze if the pump is raised in a temperature below freezing.
Follow these guidelines to avoid freezing damage:
When Guideline
Before storage • The pump must be allowed to run for a short time after raising it
to discharge remaining pumped liquid.
• The discharge opening must be covered in a suitable way, or
placed facing down so that any still remaining pumped liquid runs
out.
• If present, the cooling jacket must be drained manually by
opening the air vent screws at the top of the cooling jacket.
After storage If the impeller/propeller is frozen, it must be thawed by immersing
the pump in liquid before operating the pump.
NOTICE:
Never use a naked flame to thaw the unit.
Long-term storage
If the pump is stored more than 6 months, the following apply:
• Before operating the pump after storage, it must be inspected with special attention to the seals and
the cable entry.
• The impeller/propeller must be rotated every other month to prevent the seals from sticking together.

Monitoring equipment
The following applies to the monitoring equipment of the pump:
• The stator incorporates three thermal contacts connected in series that activate the alarm and stops
the pump at overtemperature
• The thermal contacts open at 125°C (257°F).
• Ex-approved pumps must have thermal contacts connected to the control panel.
• The sensors must be connected to either the MiniCAS II monitoring equipment or an equivalent
equipment.
• The monitoring equipment must be of a design that makes automatic restart impossible.
• The label in the junction box shows if the pump is equipped with optional sensors.
Optional sensors
FLS FLS is a miniature float switch for detection of liquid in the stator housing. Due to its design it is
best suited for pumps in a vertical position. The FLS sensor is installed in the bottom of the stator
housing.
CLS CLS is a sensor for detection of water in the oil housing. The sensor initiates an alarm when the oil
contains approximately 35% water. The sensor is installed in the bearing housing/bearing holder
with its sensing part in the oil housing. The CLS sensor is not applicable to Ex-approved pumps.
NOTICE:
The CLS sensor body is made of glass. Handle the sensor with care.
One CLS and one FLS sensor can be used in the same pump, if they are connected in parallel.
The data plate
The data plate is a metal label located on the main body of the pump. The data plate lists key product
specifications. Explosion-proof products also have an approval plate. Both are described below.

Installation
Install the pump
WARNING:
• Before installing the pump, check that the cable and cable entry have not been damaged during
transportation.
• Note that special rules apply to installation in explosive atmospheres.
• Make sure that the pump cannot roll or fall over and injure people or damage property.
• Do not install CSA-approved products in locations that are classified as hazardous in the national
electric code, ANSI/NFPA 70-2005.
NOTICE:
• Do not run the pump dry.
• Never force piping to make a connection with a pump.
These requirements apply:
• Use the pump dimensional drawing in order to ensure proper installation.
• Provide a suitable barrier around the work area, for example, a guard rail.
• Check the explosion risk before you weld or use electric hand tools.
• Remove all debris from the inlet piping system before you install the pump.
Authority regulation
Vent the tank of a sewage machine station in accordance with local plumbing codes.
Fasteners
WARNING:
• Only use fasteners of the proper size and material.
• Replace all corroded fasteners.
• Make sure that all fasteners are properly tightened and that there are no missing fasteners.
Installation
Flygt 3127 Installation, Operation, and Maintenance Manual 15

Install with P-installation
In the P-installation, the pump is installed on a stationary discharge connection, and operates either
completely or partially submerged in the pumped liquid. These requirements and instructions only apply
when the installation is made according to the dimensional drawing.
Figure 4: P-installation
These items are required:
• Guide bars
• Guide bar bracket for attaching the guide equipment to the access frame or to the upper part of the
sump
• Cable holder for holding the cable
• Access frame (with covers) to which the upper guide bar bracket and cable holder can be attached
• Discharge connection for connecting the pump to the discharge line
The discharge connection has a flange which fits the pump casing flange and a bracket for attaching
the guide equipment.
• Fasteners for the discharge connection
• Anchor bolts
1. Install the access frame:
a) Place the access frame in position and align it horizontally.
b) Grout the frame in place.
2. Grout the anchor bolts in place.
Be careful when you align and position the discharge connection in relation to the access frame.
3. Place the discharge connection in position, and tighten the nuts.
4. Install the guide bars:
a) Secure the guide bars in the bracket.
b) Check that the guide bars are placed vertically. Use a level or a plumb line.
5. Connect the discharge pipe to the discharge connection.
6. Lower the pump along the guide bars.
When it reaches the bottom position, the pump automatically connects to the discharge connection.
7. Secure the motor cable:
a) Fasten the permanent lifting device to the pump and to the access frame. For example, you can
use a stainless-steel lifting chain with shackles.
b) Fasten the cable to the cable holder.
