Pump Installation Before mounting the pump refer to the plumbing diagram opposite for maximum pipe specification. Mount the pump on a solid wall to prevent vibration. Use a back board if this is not possible. Note: If mounted to a stud wall pump vibration may cause noise through the resonance of the wall.
Plumbing of Waste Pipe Inlet and Outlet pipe must always be in 22mm. Min 1:40 fall Horizontal to waste pipe - To increase pump life ensure that 1 ⁄ ” or 1 ⁄ ” pipe is used with a gravity fall where the pipe length is greater than 1m.
Plumbing Gulley Gulley Options: For conventional gulley options for wet floor and walk in showers see page 22 and 23. Note: The Gulley must be purchased separately from your distributor. Use silicone on top of the seal to ensure proper sealing beneath the tray. Using the hand tool provided to tighten the locking ring.
Control Unit Location of Control Unit: Tighten all cable entry grommets, even unused ones, to seal the Control Unit. Locate the control unit outside the showering area in accordance with BS7671: 2008 Part Connect Control Unit to 240V a.c. supply via 7 (17th Edition).
Flow Sensor Plumbing Connection Sika sensor Flow Sensor • Fit the flow sensors with the arrow in the direction of flow to the shower, downstream of any other connections to the water supply. • Ensure flow sensor is accessible. • The flow sensors must be mounted in a straight length of unstressed pipe.
Flow Sensor Electrical Connections • Switch off the power to the control unit Sika sensor Connections before making connections. • Feed wires through cable grommets prior to connection to the control unit. • Strip wires 10mm and twist prior to inserting into spring loaded contracts.
Pump Set Up 3. Pump Speed: A simple set up is all that is required for trouble-free efficient performance of the Dry-Deck 20 system. 1.10 This sets the speed of the pump in relation to the flow rate from the sensors. Prior to making adjustments turn the shower on and wait until the pump runs.

Pump Operation 1.11 The Whale pump uses a single membrane to pump the water away. On the suction stroke, water 1.12 and debris are drawn in through the inlet valve.
Auxilary Functions 1.12a Solenoid Switch: Specification for 12V dc Solenoid Driver See diagram 1.13. Transformer The Solenoid SW terminals are to provide water shut off to the shower by the use of an additional Part No: SDA421T momentary contact switch and auxiliary solenoid Solenoids (Not Supplied with kit) drive transformer.
1.12b Pump Run Switch: See diagram 1.14. The pump run SW terminals are provided as a means by which the pump can temporarily be operated, without the shower operating, using an additional momentary contact switch. When the momentary contact switch is pressed the pump runs for 2 minutes then enters the over run cycle.
1.13 Where the situation demands or if the waste 1.16 From pump 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 advice. The discharge from the pump must go into the top of the macerator box and not into lower side entries.
