This 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.

Technical Helpline: 0845 0694 253

Thank you for purchasing this Dry-Deck 20
product. Since 1995 Whale have been the leading
manufacturer of pump kits for use with shower
trays and wet floors. 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
airing cupboard. Look at 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 i.e. airing cupboard or in a
false wall with an access panel.

Please note: incorrect installation may invalidate
the warranty.

1.1

1.1 Before mounting the pump refer to the

plumbing diagram opposite for maximum
pipe runs.

Mount the pump on a solid wall to prevent
vibration. Use a back board if this is not
possible.

The pump is mounted vertically (see
opposite) within 3 m of the gulley.

To aid servicing the head of the pump must
be above the floor by at least 150 mm
(maximum height of 500 mm).

Fix the pump in position through the feet with
the screws and washers provided.

1.2 Rotate the pump head if necessary to give a

straight run of pipe to the waste. Loosen the
clamping ring on the pump head and rotate
the head before retightening clamping ring.

Note: Do not remove the pump head.

1.3 Push fit fittings are provided to connect the

pump to inlet and discharge pipework.
All pipework in and out of the pump must be

in 22 mm.
Ensure fittings are locked after the pipe has

been pushed home.

1.4

1.4 • Only one vertical lift on the inlet to the

pump and the discharge from the pump
is allowed.

• When laying the pipe under the floor use
only slow radius bends.

• Use slow radius bends above the floor if
possible to ease the flow of water and
reduce loading on the pump.

• Use of copper pipe is recommended to
reduce risk of air leaks at connections.

• Ensure edges are burr-free. Burrs may
cause a build up of hair etc. that will
reduce flow.

• Pipework

must be secured to prevent

any vibration and noise.

• Twist lock the securing ring on the push
fit fittings (If semi rigid pipe is being used
follow the manufacturers instructions to
prevent air leaks).

1.5

The surge damper prevents water hammer

1.5 Standard Plumbing Gulley: Use silicone on

top of the seal to ensure proper sealing
beneath the tray. Using the hand tool
provided to tighten the locking flange, fit the
gulley cover into the sockets and push down
with the palm of your hand to secure.

When fitting in solid floors, remove enough
concrete for the installation of the waste
water pipe and gulley. Where copper pipe
runs under the concrete it must be lined to
protect it and prevent corrosion.

Leave the hand tool in place to prevent
building debris, grout etc. falling into the
gulley. Only remove the hand tool and fit
the gulley cover when the installation is
complete.

For alternative gulley options see page 22.

1.6

1.6 Where the situation demands or if the pipe

run is greater than that specified for the
Whale pump a macerator pump may be
used. Contact the technical helpline
(0845 0694 253) for assistance.

The discharge from the pump must go into
the top of the macerator box and not into
lower side entries.

DO NOT USE the bottom entries.
It is preferable to have two separate

discharge lines to waste and drainage when
used in the same room as a macerator
pump.

Warning: Any failure of the macerator will not
be detected by the Whale pump.

1.11a LED Display:

When not in programming mode the display
shows ‘

- -’

Water flowing through the flow sensor is
indicated by alternately flashing 'flow rate'
for flow sensor 1 and 'flow rate' for flow
sensor 2. When no water is flowing the
display flashes ‘

- -’. Flow rate is displayed

in 0.1 litre increments up to 10 ltrs and then
in 1 ltr increments.

1.11b Flow Rate Display:

When the system is not in status display
mode or configuration mode, it will display
the flow rate on the 7 segment LEDs

With no water flowing the system will
display ‘

- -’ momentarily every few

seconds
With water flowing the system will display

the following:
Sensor 1 flow rate, Sensor 2 flow rate,

Combined flow rate ... repeating
Flow rates up to 9.9 ltrs/min will be

displayed to 1 decimal place.
Flow rates of 10 ltrs/min and above will

display the rate as the nearest whole
number.

For example:

3.4 ltrs/min on inlet 1
LED show “3.4”

7.5 ltrs/min on inlet 2
LED shows “7.5”
Then total flow is displayed

LED shows “11”

1.11c Solenoid Switch:

See diagrams 1.13 and 1.14.
Aux 1 is for connection to a momentary
contact switch. When the user closes the
switch Solenoid 1 and Solenoid 2 are
energized for 30 minutes. This allows water
to flow through the shower. If the switch is
closed again the 30 minute timer starts
again.

Technical specification of solenoids.
Voltage: 24V a.c.

Power Draw: 6VA
Pressure Range: 0.2 - 10 bar

1.12a Four stages of controller operation:

1. Pump start:

The pump controller
measures the volume of water released
into the shower tray. The installer sets this
volume so that there is water in the gulley
before the pump starts thus preventing
any start up sucking noise.

2. Pumping flow rate: With the shower

running at a mid flow (8 ltrs/min) setting
the installer adjusts pump speed to match
the flow of water into the tray. This is done
by watching the level of water at the gulley
and adjusting the speed up or down as
required until the water is being pumped
away slightly faster than the flow from the
shower.

3. The pump speed-narrow setting is used to

set the pump speed at 2 ltr/min
increments above 8 ltrs/min up to the
maximum flow from the shower. This is
necessary as flow characteristics from the
pump change at higher rates.

4. Pump shut down: After the pump speed

is set the shower is turned off. When the
water is drained from the tray a gurgling
noise is heard. The electric current loading
on the pump is then stored for subsequent
use in automatically turning off the pump.

How to adjust Settings:
a.

Pressing the Mode button will
switch between the various mode
settings, indicated by small LEDs.

b. The Up and Down arrows are used

to adjust the value.

c. Press down the Mode button firmly

until the LED flashes which
indicates that the selected value
has been stored.

1.12b Switch power on to the control unit - the

LEDs will blink alternately. A simple setup
is all that is required for trouble-free
efficient performance of the Dry-Deck 20
system.

See flow chart on page 15

1.13

1. Inlet pipe size:

Programme in the size of
pipe work from the gulley to the pump.
Select 22 mm. Ignore the 15 mm setting
as this is not used for this application. With
‘22’ illuminated on LEDs hold the Mode
button down firmly until the LED blinks.

Note: This will also reset all the factory default
settings including the pump speed.

2. Pump start up:
Start delay (ltrs)

This selects the initial amount of water in
the tray before pumping starts. This should
come above the level of the gulley.
(Factory default is the minimum setting of

0.4 ltrs). Pressing the up arrow will
increase the amount of water from 0.4 ltrs
to 5 ltrs passing through the shower head
before the pump starts.

Make adjustment to this setting during final
commissioning.

Principles of Operation

Setup

1.15

3. Pumping flow rate:
Pump speed settings

Prior to making adjustments turn the
shower on

and wait till the pump runs.

Set the shower flow rate to 8 ltrs/min.
Watch the level of water within the shower

using the gulley cover as a guide. If the water
level is lowering then reduce the speed of the
pump by pressing the Down arrow. Use initial
increments of 5 until fine tuning is required.
When the water level is rising then increase
the speed of the pump by using the
Up arrow.

After making a change watch the water level.
Wait at least 30 seconds, as the system
needs to stabilise, until you see if the water is
rising or falling. When the water level is
slightly over pumping, program in the speed
setting by pressing the Mode button firmly
until the LED blinks

4. Pump speed – Narrow setting

This setting is required for higher flow rates.
a. 'Pump speed' must be set first as per

above using a mid-range flow setting.

b. Increase the flow from the shower in

increments of 2 litres and watch the
water level around the shower gulley. If
this is rising or falling over time make
adjustments until a constant level is
observed then programme in the
setting.

c. This process is repeated in 2 ltr

increments. The narrow adjustment
corrects the flow rate over a band 1
ltr/min either side of the flow rate that is
being calibrated.

5. Pump shut down:­Over Run (Auto Sense) preferred option

To set Auto Sense Over Run (indicated by
'AS' on the LED) you must turn off the
shower when you have selected this mode.
When the pump is drawing air there will be a
gurgling noise at the gulley, press down the
Mode button so the controller stores the
loading on the pump at this point.

Over Run (Fixed)

Alternatively to set a fixed Over Run delay
use the Up and Down arrows. Each digit
represents a delay of 5 seconds
(i.e. 2 =10 seconds over run).
Hold the Mode button down to program.

Commissioning Checklist

a.

All push fit fittings must have the twist
lock in the locked position.

b. Check all plumbing for leaks.
c. Check waste water plumbing for leaks

while pump is running.

d. Ensure flow sensor is unstressed.

After programming all the settings, turn the
shower on and check for correct operation.
Make final adjustment to the Start Delay if
required.

Note: 15 minutes after showering is finished, the
pump will switch on for a brief period in order to
remove any water that may have pooled.

1.14 The Whale Gulper pump uses a single
membrane to pump the water away. On the
suction stroke, water and debris are drawn in
through the inlet valve. With a chamber full of
water the pump discharges the water
through the two non-return valves on the
outlet. The two outlet valves protect the
pump against losing prime. The aggressive
flushing keeps the pump valves clear of
debris resulting in a pump which does not
require regular maintenance.

Unlike other pumps, the Whale Gulper has
the ability to run dry without causing damage
to the pump.

An additional advantage of the three
nonreturn valves in the pump head, is that no
smells can be passed back from the waste
stack into the shower area.
