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 a concealed access.
Assess your installation prior to fitting to ensure that the unit will be situated in an accessible location.
Typical installations would have these components in an adjacent cupboard i.e. airing cupboard or in a false
wall with an access panel. Do not fit the pump cover in these locations.
Incorrect installation may invalidate the warranty.
Plumbing of the Waste Pipe

Principles of Operation

This kit has been designed for the pumping of shower waste water. The Instant Match Premium control unit uses flow
sensors to measure the flow rate of water into the shower. The control unit uses the signals sent from the flow sensors
to adjust the pump speed to match the flow of water from the shower. This minimises suction noise at the gulley. When
the shower is turned off, the flow sensors send a signal to the control unit and after a pre-set time delay the pump turns
off. After a further 15 minutes the pump will automatically switch on for a short period of time at a reduced pumping
speed, removing any run off water pooled in the shower area. The pump has the ability to run dry without causing
damage. Non-return valves in the pump head prevent smells from entering the bathroom area from the waste pipe.
Installation Warnings
Before installation please read the instructions. All electrical and mechanical components (Transformer, Pump and Sika
flow sensors) must be accessible after installation.
• The Instant Match Premium is designed to work on shower bases with a minimum of a 1:40 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 as this eliminates the risks of pooling caused by insufficient fall to the gulley.
• Forming a shower base by hand is a highly skilled task and must be carried out by a trained installer. Do not
attempt this if you are unsure and seek professional advice.
• The maximum flow rate of the shower that the pump is designed to work with is 12 ltrs/min.
• Avoid plumbing the pump outlet into the waste piping that other appliances drain into as there is a risk of
induced syphoning. Use an anti-syphon trap in these situations. (See page 7)
• In installations where the floor is being formed in the screed, we recommend the following minimum falls:
40mm in 1m, 20mm in 500cm,10mm in 250cm.
• Plumbing must comply to latest WRAS standards.
• The electrical wiring must conform to EU wiring regulations BS7671:2008 Part 7 (17th Edition).
• Pipework must be secured to prevent vibration and noise.
• Ensure that the water fall from the shower head is as close to the gulley as possible.
