When looking at a whirlpool bath you must establish the reference point, which is the suction cover. When standing directly in front of the bath the suction cover should be right beneath you. (The Mito™ is an exception to this rule. For this unit the suction cover will be across from you.) Having located the suction cover:
On an end-drain bath, the right hand or left hand designation refers to the location of the drain.
On an end-drain bath, the pump and motor location will be at the opposite end from the drain.
On a center-drain bath, the right hand or left hand designation refers to the pump and motor location.
An Authorized Jacuzzi Bath Dealer or Distributor can provide you with additional information for your particular application.
