Plumbing Specification
1.3
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.
• 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 flow rate
8 ltrs/min, (15mm pipework on the inlet to the pump/
22mm pipework on the outlet).
• Mixer Shower Installations – Maximum flow rate
12 ltrs/min, (22mm pipework on the inlet to the pump/
22mm pipework on the outlet).
Note - An additional flow sensor (Part No. SDP223T) and 22 mm
fittings are required.
• Use slow radius bends where possible. Use formed
bends or elbow fittings – 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-fit fittings and
'Twist Lock'. Do not stress pipe at connection.
1.4
• 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 floor. The pump may be mounted horizontally on the floor
if required.
• The shower floor must have a fall of at least 1:40.
• Pump, flow 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
1.5
• Do not combine pump discharge with other
appliances as there is a risk of induced syphoning.
Use an anti-syphon trap where necessary.
