Thank you for purchasing this Whale® product.
For over 40 years, Whale® has led the way in the design and manufacture of freshwater and waste systems
including: pumps, plumbing faucets, showers for low voltage applications. The company and its products have built a
reputation for quality, reliability and innovation backed up by excellent customer service.
Typical Installation
The Watermaster® IC is designed for use in recreational vehicles to simplify the supply of freshwater to caravans
and motorhomes, where a Whale® High Flow Watermaster® pump is used to supply the taps and showers.
The Watermaster® socket (already installed or available separately)
must be
mounted so that the rear of the socket
is accessible from within the vehicle.
Ensure at least 30mm clearance below the socket to allow for wiring. Following a “once only” calibration the
Watermaster® IC unit removes the need for adjustment of the pressure switch, removes the requirement to have a
surge damper in the system and switches off the pump when it runs dry. For information on our full product range

This product is designed for use with freshwater. If it is intended for use with any other liquid, it is the user’s
responsibility to ensure that the materials are fully compatible with the liquids to be used and that a system of safe
working practice is applied to installation, use and maintenance.
