Commissioning
Safety
DANGER! Danger of death!
Failure to install safety devices on the terminal box or near the
coupling can cause electrical shock or contact with rotating parts,
potentially resulting in life-threatening injuries.
• Before commissioning, all safety devices (such as terminal box
covers or coupling covers) that were removed must be reinstalled.
• Keep a safe distance during commissioning!
WARNING! Risk of injury!
If the pump/system is installed improperly, liquid may be ejected
during commissioning. Individual components may also become
loose.
• Keep a safe distance from the pump during commissioning.
• Wear protective clothing, protective gloves and protective gog-
gles.
NOTE:
It is recommended to have the pump serviced and checked by Salm-
sonCustomer Service.
Preparation
The pump has to reach ambient temperature before commissioning.
8.1
Initial commissioning
• Check whether the shaft can be rotated without any grinding. In case
the impeller is blocked or grinds, loosen the coupling screws and
tighten them with the specified torque (see the table in chapter 9.4
“Screw tightening torques” on page 43).
• Fill and bleed the system as required.
WARNING! Danger due to extremely hot or extremely cold pressu-
rised fluid!
Depending on the temperature of the fluid and the system pres-
sure, when the vent screw is opened completely, extremely hot or
extremely cold fluid in liquid or vapour may escape or shoot out at
high pressure.
• Always exercise caution when opening the vent screw.
CAUTION! Risk of damage to property!
Dry running will destroy the mechanical seal.
• Make sure that the pump does not run dry.
• To avoid cavitation noise and damage, a minimum intake pressure
must be guaranteed at the suction port of the pump. This minimum
intake pressure depends on the operating situation and the duty point
of the pump, and must be defined accordingly.
The main parameters for defining the minimum intake pressure are
the NPSH of the pump at its duty point and the vapour pressure of the
fluid.
• By briefly switching on, check whether the direction of rotation
agrees with the arrow on the fan cover (see Fig. 41, Item 2). If the
direction of rotation is incorrect, proceed as follows:
• For Y-
Δ
start, swap the winding start and winding end of 2 windings
on the motor terminal board (e.g. V1 for V2 and W1 for W2).
