Grundfos that the pump be installed with sound and vibration dampening equipment such as;
flexible piping adapters and anti-vibration mounting. The pump should not be mounted in or
adjacent to living quarters. The pump can also be wrapped with sound proofing insulation to
reduce noise. (See page 16, EZ Boost System Diagram.)

EZ Boost Controller
The EZ Boost controller is a control and communication
unitespeciallydevelopedfortheBMQEboosterpumpsin
constantpressureapplications.
TheEZBoostcontrollerprovides:
• FullcontroloftheBMQEpumps
• Two-waycommunicationwiththeBMQEpumps
• Possibilityofadjustingthepressure
• Alarmindication(LED)whenserviceisneeded
• The possibility of starting, stopping and resetting the
 pumpsimplybymeansofapush-button
TheEZBoostcontrollercommunicateswiththepumpvia
powerlinecommunication,meaningthatno extracables
arerequiredbetweentheEZBoostcontrollerandtheBMQE
pump.
TheEZBoostcontrollerfeaturesthefollowingindications
(seedrawingbelow):
1. Flowindicator
