1. Location of the pump
The best possible location for the pump is
at or near the base of the cylinder at least
600mm below the bottom of the cold water
storage tank. Where it is not physically
possible to locate the pump next to the
cylinder, the pipe run from the hot water
cylinder to the pump must not exceed 4m in
22mm pipe work.
1.1 Cooling and ventilation
The pump should be placed in a position
where there is an adequate air flow to cool
the motor and separated from any other
appliances that generate heat. It should be
installed in a clear space allowing 100mm
additional space at each side, the ends and
top of the pump.
1.2 Frost protection
Loft mounted pumps must be protected
from frost damage.
2. Hot and cold supplies
to the pump
Never fit the pump directly to the cold
water mains.
Never fit to communal risers (e.g. block of
flats) or secondary circuits that are pumped.
The pump must be fed by exclusive hot and
cold water supplies (i.e. not shared with other
services) and in 22mm pipe work (Note: for
the RSP 50 a maximum of 2m of 15mm inlet
pipe work).
The hot supply pipe work should be a
maximum of 4m from the cylinder in 22mm
pipe work.
All up and over pipe work must be vented at
the highest point on the outlet of the pump
Please follow these installation instructions carefully. Failure to install your pump
in accordance with these instructions will invalidate your warranty.
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:
and a non-return valve (NRV) may require to
be fitted to the hot outlet only (Note: for the
ESP range this is for the ESP 50 CPV and
ESP 55 CPV only).
2.1 For pumps positioned above
the hot outlet, hot water
cylinder or in a loft
An anti-gravity loop (AGL) off a No stop
Essex Flange must be used when it is sited
above the dome of the hot water cylinder
as it prevents air tracking up into the pump
chamber and back siphoning of the water
again, creating air in the pump chamber.
Never put a non-return valve, inverted loop,
restrictive balofix or an air vent on the supply
pipe work to a pump.
Where the pump is servicing two or more
bathrooms, the cold water supply to the
cylinder must be in 28mm pipe work.
2.2 Cold water storage
Ensure that the cold water storage capacity
is adequate for all of the household
requirements (minimum 50 gallons per
bathroom, 80 gallons for one bathroom and
one en-suite shower room).
Ensure the cold water supplies to the cylinder
and the pump are taken from the opposite
side of the cold water storage tank from the
cold mains inlet.

OLD STYLE DO NOT USED
Fig 2
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 1.0 bar pressure) –
only exception is the ESP 50 CPV which
is 5m (equivalent to 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 60-65ºC
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
shower pump
Never connect to a secondary return
tapping on a hot water cylinder
