URGENT Positive or negative pump

[Terry P]

Hansgrohe Raindance Select E Shower System 120 with Showertablet Select Thermostatic Mixer and Shower Rail 90cm - 27027400

This shower states can be used with a universal (negative head) pump but my pump is a gravity fed positive head installation. My question is would I be ok to use this shower with my existing pump?
