Pre-installation Checklist
Our pre-installation guidelines are detailed on the following pages, but some of the key
“do’s and don’ts” are highlighted below:
Do’s
Locate the pump next to the hot water cylinder within 5m of measured pipe. 2m MAX of
15mm pipework on inlet connections may be used.
Allow 100mm on all sides for ventilation
Ensure pump is protected from frost
If servicing two or more bathrooms, cold water supply to the cylinder
must be in 28mm pipework
Ensure adequate cold water storage (227 litres (50 gal) per bathroom,
364 litres (80 gal) for one bathroom and one en-suite)
Cold water supplies to the pump must be taken from the opposite side of
the cold water storage cistern to the cold water mains inlet
Multiple cold water storage cisterns must be linked in accordance with current
plumbing regulations and the bottom of the cisterns must be at the same level
Hot water supply to the pump must be via a Salamander approved method.
AV couplers must only be finger tight plus one quarter turn
The maximum static head should be 10m (equivalent to 1.0bar pressure)
We recommend the pump is activated for at least 5 minutes every 4 weeks
to ensure pump does not seize.
Ensure that installation complies with IET wiring regulations.
All AV hoses should be fitted straight with no twists or bends.
Ensure suitable means of isolation for maintenance
Bathroom Zones: Salamander products covered in these notes cannot be installed
in Zone 0 or Zone 1. They can however be installed in areas that are accessible with
a tool. (see Step 1 Pump Location for further information (Fig 5))
