equipment is recommended but locally approved equipment of suitable rating may be used. While lifting,
the equipment adjusts the center of gravity, so that it is balanced properly.
Do not place fingers or hands etc into the suction or discharge pipe outlets and do not touch the impeller, if
rotated this may cause severe injury. To prevent ingress of any objects, retain the protection covers or
packaging in place until removal is necessary for installation. If the packaging or suction and discharge
covers are removed for inspection purposes, replace afterwards to protect the pump and maintain safety.

SAFETY INSTRUCTIONS WHILE ASSEMBLY & INSTALLATION
Shaft alignment must be checked again after the final positioning of the pump unit and connection to
pipework as this may have disturbed the pump or motor mounting positions. If hot liquids [above 80
° C] are
being pumped, alignment should be checked and reset with the pump and motor at their normal operating
temperature. If this is not possible, KBL can supply estimated initial offset figures to suit extreme operating
temperatures. Failure to support suction and delivery pipework may result in distortion of the pump casing,
with the possibility of early pump failure.

SAFETY INSTRUCTIONS WHILE COMMISSIONING & OPERATION
Never attempt adjustments while the pump is running, unless otherwise specified in the operation,
maintenance manual.
Do not touch any moving or rotating parts. Guards are provided to prevent access to these parts, where
they have been removed for maintenance they must be replaced before operating the equipment.
Check that pump is primed. Pump should never be run dry as the pumped liquid acts as lubricant for the
close running fits surrounding impeller and damage will be incurred.
Failure to supply the stuffing box or mechanical seal with cooling of flush water may result in damage and
premature failure of the pump.
Do not touch surfaces, which during normal running will be sufficiently hot to cause injury. Note that these
surfaces remain hot after the pump has stopped, allow sufficient time for cooling before maintenance. Be
cautious and note that other parts of the pump may become hot if a fault is developing.
Do not operate water pumps in temperatures below freezing point, without first checking that the pumped
fluid is not frozen and the pump is free to turn. Pumps in these environments should be drained down
during inactivity and re-primed before starting.
In addition to local or site regulations for noise protection, KBL recommend the use of personal ear
protection equipment in all enclosed pump rooms and particularly those containing diesel engines. Care
must be taken to ensure that any audible alarm or warning signal can be heard with car defenders worn.
Be aware of the hazards relating to the pump fluid, especially the danger from inhalation of noxious and
toxic gases, skin and eye contact or penetration. Obtain and understand the hazardous substance data
sheets relating to the pumped fluid and note the recommended emergency and first aid procedures.

SAFETY INSTRUCTIONS WHILE MAINTENANCE & SERVICING
Do not attempt repairs of the pump or its accessories which you do not know. Use proper tools.
Before attempting any maintenance on a pump particularly if it has been handling any form of hazardous
liquid, it should be ensured that the unit is safe to work on. The pump must be flushed thoroughly with
suitable cleaner to purge away any of the product left in the pump components.
This should be carried out by the plant operator and a certificate of cleanliness obtained before starting
work. To avoid any risk to health it is also advisable to wear protective clothing as recommended by the
site safety officer especially when removing old packing, which may be contaminated.
