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 OR no further than 4m away in
22mm pipe work
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 pipe work
Ensure adequate cold water storage
(50 gallons/bathroom, 80 gallons 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 tank to the cold
water mains inlet
Multiple cold water storage tanks must
be linked in 28mm pipe work and the
bottom of the tanks must be at the
same level
Hot water supply to the pump must be
via a Salamander approved flange
AV couplers must only be finger tight
plus one quarter turn
The maximum static head should be
10m (equivalent to 100kPa/1.0 bar
pressure) – only exception is the
RP50TU which is 5m (equivalent to
50kPa/0.5 bar pressure)
We recommend the pump is activated
for at least 5 minutes every 4 weeks
Don’ts
Never fit the pump to the cold
water mains
Never fit the pump to communal risers
Never use a shared water supply
Never put a non-return valve (NRV),
inverted loop, restrictive balofix or an
air vent on supply pipe work to the pump
The hot water supply to the pump must
not exceed 60ºC
Never twist the anti-vibration (AV)
couplers or bend more than 35º
Never use mechanical tools to tighten
coupler nuts as this may cause damage
and will invalidate your warranty
Never use jointing compounds,
Boss White, Hemp or steel wool
Solder fluxes must not come into
contact with the pump or AV couplers
Never install in a bathroom unless in
an enclosed space and access is only
possible with an appropriate tool
Never pump directly to or from another
pump
Never connect to a secondary return
tapping on a hot water cylinder
BEFORE INSTALLATION OF YOUR NEGATIVE HEAD
PUMP:
Please fit the pressure vessel if packaged seperate
to the pump. Use the
½ “ flat rubber washer in the
½ “ brass connection on the top of the pump junction
box. Screw the pressure vessel into the connection hand
tight.
