Thank you for purchasing this Dry-Deck 20
product. Whale is the market leader in pumped
shower drainage kits. These kits have the
reputation of working reliably for many years
without requiring maintenance.
The front cover shows the product installation in an
apartment with the components in an adjacent
room accessed via a cupboard. Assess your
installation prior to fitting so that the pump, surge
damper, control unit and sensors are in accessible
positions.
Typical installations would have these components
in an adjacent cupboard or in a false wall with an
access panel.
Incorrect installation may invalidate warranty.
Principles of Operation
This kit has been designed for the pumping of
shower waste water.
• The Dry-Deck 20 control unit uses flow sensors
to measure the flow rate of water into the
shower.
• The pump speed is controlled directly by the
control unit which uses the signals sent from the
flow sensors to adjust the pump speed to
match the flow from the shower. This minimises
suction noise at the gulley.
• A simple setup is required to match the pump
performance to the characteristics of the
installation.

The Dry-Deck system is designed to work on
shower bases with an adequate fall to the gulley.
Where the fall is insufficient, the water will not refill
the gulley rapidly enough and so suction noise will
be increased. We recommend the use of a shower
former i.e. Impey Aqua Dec or equivalent. This
eliminates the risks of puddling or insufficient fall to
the gulley.
Forming a shower base by hand is a highly skilled
task and should be carried out by a trained
installer. Do not attempt this if you are unsure and
seek professional advice.
