This kit has been designed for the pumping of shower
waste water.

• When the shower is turned on the ow sensor(s)
measure the ow rate of the water into the shower.

• The pump speed is controlled directly from the control unit
which uses the signals sent from the ow sensor to adjust
the pump speed to match the ow 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.

• When the shower is nished the pump will automatically
switch on after 15 minutes to remove any water pooled in
the showering area.

• The pump has the ability to run dry without causing
damage to the pump.

• Before installation please read the instructions.

• Plumbing installation must comply with the plumbing
regulation as specied in the latest WRAS leaet for
plumbing systems.

• The electrical wiring must conform to
BS7671: 2008 Part 7 (17th Edition).

• Contact the Technical Helpline
(0845 0694 253) if you need further assistance.

The front cover illustrates the product in typical Digital
Smoothflow installations (Mixer Shower Installation).

Assess your installation prior to fitting so as to ensure
that the pump, Digital Smoothflow Control Box and flow
sensor(s) will be situated in an accessible position.

Typical installations would have these components in an
adjacent cupboard i.e. airing cupboard or in a false wall
with an access panel.

Incorrect installation may invalidate
the warranty.

Before installation read the instructions

All electric and mechanical components (control unit, pump
and ow sensors) must be accessible after installation.

• The maximum ow rate the pump is design to work with is
8 Itrs/min for 15mm (electric shower) and 12 ltrs/min for
22mm mixer shower installations.

• Avoid plumbing the pump outlet into the waste piping that
other appliances drain into as there is a risk of induced
s

yphoning. Use an anti syphon trap in these situations.

• With installations where the oor is being formed in the
screed, we recommend the following minimum falls:
30mm in 1m, 15mm in 500cm, 7.5mm in 250cm.

• Plumbing installation must comply to latest WRAS
regulations.

• The electrical wiring must conform to EU wiring regulations

• Mount pump, head down, as shown. See Fig 1.4

• Mount the pump on a solid wall to prevent vibration.

Note: If mounted to a stud wall pump vibration may cause noise through
the resonance of the wall. In these situations mount the pump on a
bracket off the oor. The pump may be mounted horizontally on the oor
if required.

• The shower oor must have a fall of at least 1:40.

• Pump, ow sensor and control box must be
accessible after installation.

• Use a maximum of one vertical lift to the pump and
one vertical rise from the pump. See Fig 1.3

• The pump inlet should point towards the gulley and
the gulley outlet should point towards the pump to
keep connecting pipework as straight as possible.

• Rotate the pump head if necessary to connect the
gulley to the pump by the most direct route. Loosen
clamping ring screw, rotate and retighten as shown.

See Fig 1.5 and 1.6

• Do not combine pump discharge with other
appliances as there is a risk of induced syphoning.
Use an anti-syphon trap where necessary.

• Whale

®

pump is IP45 compliant. Locate pump in
accordance with BS7671: 2008 part 7 (17th Edition).
The pump may be installed in zones 1, 2 or 3.

• Electric Shower Installation – Maximum ow rate

8 ltrs/min, (15mm pipework on the inlet to the pump/
22mm pipework on the outlet).

• Mixer Shower Installations – Maximum ow rate

12 ltrs/min, (22mm pipework on the inlet to the pump/
22mm pipework on the outlet).

Note - An additional ow sensor (Part No. SDP223T) and 22 mm
ttings are required.

• Use slow radius bends where possible. Use formed
bends or elbow ttings – not stem elbows.

• Inserts should not be used with plastic waste pipe.

• Ensure pipe edges are burr-free.

• Pipework must be secured.

• Push home pipe into push-t ttings and
‘Twist Lock’. Do not stress pipe at connection.

Plumbing Specification

1.5 1.6

Maximum pipe length for typical installation

- extra elbows will reduce performance.

Pipe from gulley to pump must be 15mm for
electric shower installations and 22mm for
mixer valve installations. Failure to do this
will effect pump performance.

WARNING

• Before running water through the system ensure that
the shower area and gulley are completely free of debris.

• For pump mounting instructions. See Fig 2.3, Page 7

Orientate gulley so that it exits towards the pump inlet
to avoid unnecessary bends.

• When tting in solid oors if copper pipe is used, it must be
sheathed to prevent corrosion.

T

ray Gulley

• The tray gulley has a 35 mm prole to enable the shower
drain to t into a screed oor without penetrating the
damp-proof membrane. See Fig 1.7

• Use silicone on top of the seal to ensure proper sealing
beneath tray.

• Use the hand tool provided to tighten the locking ange.

See Fig 1.8

• Fit the gulley cover into the sockets and push down to
secure. See Fig 1.9

Wetoor Gulley

• The wet oor gulley has a 40 mm prole to enable it to t
into a screed oor without penetrating the damp-proof
membrane. See Fig 2.0

• Where no tray former is used the gulley has two lugs either
side of the discharge pipe to enable the gulley to be xed
to the oor whilst screed is laid around the gulley.

• Where a tray former is used these lugs can be broken off
easily and the gulley mounted into the
160 mm gulley opening.

• The gulley has a conventional clamping ring to
accommodate vinyl ooring.

• The gulley cap clicks into place and may be easily removed
for cleaning if required.

Other Gulley’s

• The pump may be used with gravity style gullies. Use
reducing couplings to achieve 22mm pipe run to pump.

Top Tip: Leave the hand tool in place to prevent building debris,
grout etc. falling into the gulley. Only remove the hand tool and t
the gulley cover when the installation is complete and the shower
area has been thoroughly cleaned.

• The outlet of the pump may be connected into the
waste pipe, e.g. former bath waste. Black rubber
ttings are provided for this.

• In conned bathrooms pump discharge may go into
the sink waste pipe using suitable adaptors.
See Fig 2.1 for McAlpine examples and their catalogue for
other variants.

U

se with a Macerator Pump

• Discharge from the Whale pump must go into the

top of the macerator box. Do not use the bottom entries.
See Fig 2.2

• It is preferable to have two separate discharge lines
to waste as any failure of the macerator will not be
detected by the Whale pump.

• Avoid plumbing the pump outlet into the waste piping that
other appliances drain into as there is a risk of induced
syphoning. Use an antisyphon trap in these situations.

Use the backplate as a

template to mark the position

of the mounting holes.

Use a 6 mm bit to drill holes

at marked points and insert

No 6 wall plugs.

Use pliers to open up desired cable entry
point on backplate. Don’t use top centre

entry. X = DO NOT USE

To t cover, locate bottom lug into

backplate, and pivot cover forward until

top clips click into place.

To remove cover, use two hands to push backplate clips together.

As clips disengage, the cover will fall forward and may be lifted away.

If the pump is misaligned on the backplate
or pump head is not parallel with backplate
the push-t connectors may prevent the
front cover from tting properly. Adjust
pump, pump head or connecting pipework
to achieve a good t.

Use of elbows on pump inlet and outlet
should be avoided. If the situation demands
that they are used, ONLY use John Guest
push-t elbows. Other types are not readily
demountable and may foul the cover.

Fix pump to wall using No 8 screws. Use crimps supplied to terminate 24V d.v.

cable from transformer, connect to pump and feed cable through entry point.

Hold cable in place using adjacent cable bracket.

STATEMENT OF LIMITED WARRANTY

The products manufactured and supplied by the Company (“Products”), are warranted to be free from material defects in
design, workmanship and material under normal use (“Defects”) for (unless otherwise extended in advance in writing by
the Company) a period of 3 years from date of purchase, save that this warranty shall not apply where the Defect is
attributable to defective materials supplied by third parties. In such event, the only remedy of the buyer of the Products
(“Buyer”) will be against that third party.

This warranty applies only to Products that are properly installed and used in accordance with all oral and written
maintenance and operation instructions provided by the Company. The Company shall not be liable for a breach of any of
the warranties in this Statement of Limited Warranty if the Buyer makes any further use of the Products after giving the
Company notice of any Defect or the Buyer alters or repairs such Products without the written consent of the Company.

Products that have been disassembled or modied (without prior written approval of the Company), are not covered by

this warranty.

All Products are covered by a 3 year limited warranty (detailed below) from (unless otherwise extended in advance in
writing by the Company) date of purchase (“Standard Warranty”). In addition to the Standard Warranty, these Products
will be covered by a further warranty of 2 years but only when the registration form is completed and returned
(“Additional Warranty”). The period of such Additional Warranty shall commence automatically the date the Standard
Warranty expires.

In the event that any of the warranties offered by the Company are breached, the Company shall (at its discretion) repair,
replace or issue a spares kit for the defective Product subject to prior examination at Company premises. If the Company
complies with this paragraph, it shall have no further liability for a breach of the warranties in respect of such Products.
Adjustment or replacement of defective parts made under this warranty will not extend the warranty period applicable
either under the Standard Warranty and/or the Additional Warranty.

The Company shall not bear any costs of removal, installation, transportation, or other charges that may arise in

connection with a warranty claim by the Buyer. Such costs shall be the Buyer’s sole responsibility.

No claim in respect of defective Products will be valid unless the alleged defective Products are returned at the Buyer’s

expense to the Company for inspection, together with proof of purchase.

Non-stock/ special order items are non-returnable by the Buyer in any circumstances, and this warranty does not apply to
prototype models.

EXCLUSIONS:

The Company shall not be liable for any indirect loss or for any special, incidental, punitive or consequential damages
suffered by the Buyer and/or any third party, whether this loss arises from breach of a duty in contract or tort or breach of
a statutory duty or in any other way, including, without limitation, loss arising from the negligence, default, breach of duty,
non-delivery, delay in delivery or defects or errors in the work undertaken by the Company pursuant to the terms of this
Statement of Limited Warranty or in connection with any other claim arising in connection with manufacture and/or supply
of the Products.

In particular, the Company shall not be liable (without limitation) for:

• Loss of prots, increased production costs or other economic injury or loss;

• Loss of contracts or opportunity; and/or

• (insofar as is permitted by applicable law) damage to property of the Buyer or any third party.

The Company shall under no circumstances be liable for any breach of its obligations hereunder and/or under any
contract governing sale and purchase of the Products (“Contract”) resulting from causes beyond its control including but

not limited to res, strikes, lockouts, insurrection or riots, terrorism or civil disorder, embargoes, wrecks or delays in

transportation, requirements or regulations of any governmental authority, tempest, earthquake or other natural disaster,

ood, bursting or overowing of water tanks, failure or shortage of power, fuel or other utilities, or loss of data and/or

communications due to causes such as those referred to in this paragraph.

R

This statement sets out the Company’s entire liability in respect of the Products and the Company’s liability under this

statement shall be in lieu of all other warranties, conditions, terms and liabilities, express or implied, statutory or otherwise
howsoever except any implied by law which cannot be excluded.

All warranties, conditions and other terms implied by statute or common law (save for the conditions implied by section
12 of the Sale of Goods Act 1979) are, to the fullest extent permitted by law, excluded from the Contract.

Subject to the remaining provisions of this Statement of Limited Warranty, the Company’s total liability in contract, tort

(including negligence or breach of statutory duty), misrepresentation, restitution or otherwise, arising in connection with
the performance or contemplated performance of the Contract and supply of the Products shall be limited to the Contract
price.

Nothing in this Statement of Limited Warranty shall operate so as to exclude or restrict the Company’s liability for death

or personal injury caused by its negligence.

The Company shall NOT be liable for any condition, warranty or representation made by a distributor or other person

acting on behalf of the Company unless expressly conrmed by the Company in writing.

This Statement of Limited Warranty shall be governed and construed in accordance with Northern Irish law and all disputes
arising in connection hereto shall be submitted to the exclusive jurisdiction of the Northern Irish Courts.
