Pre-Installation Checklist
Our pre-installation guidelines are detailed on the following pages, but some of the key “do’s and
don’t s” are highlighted below:
Do’s
• Locate the pump next to the hot water
cylinder or within 5 metres of measured
pipe - 2m MAX of 15mm pipe on inlet
connections
• Ensure 100mm on all sides for ventilation
• Ensure pump is protected from frost
• If servicing two or more bathrooms, cold
water supply to the cylinder should be
ideally in 28mm pipework
• Ensure adequate usable cold water
storage - 227 Litres (50 Gal.) per
bathroom and 136 Litres (30 Gal.) per
en-suite or shower
• 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 to current regulations with their
bases level
• Hot water supply to the pump must be
via a Salamander approved anti-aeration
flange
• Always use an Essex Flange where there
is less than 1m between the top of the hot
water cylinder and base of the cold water
cistern
• 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 are the RP50TU and the
RP55SU which is in 5m (equivalent to
50kPa/0.5 bar pressure)
• We recommend the pump is activated
for at least 5 minutes every 4 weeks to
exercise all moving parts
Don’ts
• Never fit the pump to the cold water
mains
• Never fit the pump to communal risers or
cold water storage cisterns
• Never use a shared water supply or
shared cold water cistern
• Never put a non-return valve (NRV),
inverted loop, restrictive ballofix or an air
vent on supply pipe work to the pump
• The hot water supply must not exceed
65°C
• Never twist the anti-vibration (AV)
couplers or bend more than 35°
• Never use mechanical tools to tighten
plastic coupler nuts as this may cause
damage and 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 any pump
such as a secondary return pump or
boosted shower
• Never connect to a secondary return
tapping on a hot water cyclinder without
the use of dip tube into the cylinder
• Never fit to a Primatic cylinder, Andrews
type water heater, Elson Tank or Fortic
type cylinder
• It is not recommended to pump hot water
against cold mains water with a positive
head pump

1. Location of the pump
The best location for the pump is at the base of
the cylinder. 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 5m, ideally in 22mm
with no more than 2m of 15mm pipe to supply
the pump.
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).
The hot supply pipework to the pump should be
a maximum length of 5 metres in 22mm pipe
(where unavoidable, hot and cold supplies may
have maximum 2 metres of 15mm pipe).
All up and over pipe work must be vented at
the highest point on the outlet of the pump and
a non-return valve (NRV) may require fitting
to the hot outlet only (Note: this is only for the
RP50TU and RP55SU).
2.1 For pumps positioned
above the hot outlet, hot
water cylinder or in a loft
Where the pump is located above the hot
water cylinder, it must be a minimum of
600mm below the cold water cistern.The best
connection is a No-Stop Essex Flange in 22mm
with an Anti-Gravity Loop (AGL) of 400mm
(Figure 7), Alternatively, a top entry flange
may be used. If aearation causes an issue, it
may become a requirement to use an Essex
Flange.
2.2 Cold water storage
Ensure that the cold water storage capacity
is adequate for all of the household
requirements (minimum 50 gallons/227 Litres
per bathroom, 80 gallons/385 Litres 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.
Figure 1: Tank inlet and outlet position
Please follow these installation instructions carefully. Failure to install your pump in
accordance with these instructions will invalidate your warranty.

Multiple cold water storage (CWS) tanks must
be linked top and bottom in 28mm pipework
and fitted with float operated valves in all
tanks. Always link to comply with the Water
Supply (Water Fittings) Regulations 1999.
Figure 2: Linked cold water tanks
2.3 Hot water requirements
The stored hot water temperature must not
exceed 65ºC (see page 18, Stored hot water
temperature).
The hot water supply to the pump must be via a
Salamander approved method:
The best hot connection from the cylinder is
either
• A 3⁄4” No-Stop Essex Flange. See Figure 3 or
• A Salamander S flange or other approved top
entry flanges. See page 16/17.
Figure 3: Hot water supply method
3. Anti-vibration couplers
(Hoses)
The anti-vibration (AV) couplers are designed
to limit the transfer of pump vibration to the
associated pipe work. All Salamander AV
couplers are ¾” BSP x 22mm push fit with
built-in isolating valves. Note: the RP50PTis
supplied with 15mm couplers with isolating
valves on the inlets and outlets.
Figure 4: Isolating valves
Figure 5: Couplers
Ideally the AV couplers should be straight, but
they must NOT be twisted or bent more than
35º (this invalidates the warranty). See Figure
5 above.

Straight hoses must be used on the outlets.
Hoses should not be over tightened or be
tightened with mechanical tools.
4 General plumbing
The installation must comply with the relevant
requirements and local by-laws.
The pump MUST be mounted upright (shaft
horizontal, not screwed down).
Jointing compounds, Boss White, hemp or steel
wool MUST NOT be used. Solder fluxes must
not come into contact with the pump or AV
couplers.
The maximum static head should be 10m
(equivalent to 100kPa/1.0 bar pressure)
with the exception of the RP50TU & RP55U
where the maximum static head should be 5m
(equivalent to 50kPa/0.5bar pressure)
The plumbing installation must comply with
“The Water Supply (Water Fittings)
Regulations 1999” and “BS EN 806-4:2010”
buildings regulations.
5 Electrical requirements
The pump must be connected to the electrical
supply using the mains cable with the attached
plug. This plug must be connected to an
accessible socket that has been installed in
compliance with BS 7671
(I.E.T. Wiring Regulations). The plug must be
accessible at all times.
The pump must not be installed in a bathroom
unless it is installed in an enclosed space
accessible only with the use of a tool.
If the supply cord is damaged, it must be
replaced by the manufacturer, its service
agent or similarly qualified person in order to
avoid a hazard.
Higher rated fuses must NOT be used. Fuses
should be as per the table below:
Pump Fuse

Typical Installation
Right Pump
Positive Range
The selection of the Right pump positive for a
system will be determined by the resistance
of, quantity of and pressure required by, the
outlets.
To activate a positive head pump :
1 litre per 30 seconds (2 L/min) of water
should be able to flow through each side of the
pump naturally and out of the tap or shower.
This will lift the flow switches and turn the
pump on.
Where this flow cannot be achieved, a negative
head pump is required.

Right Pump
Universal - System
Operation
Negative head systems
Negative head systems exist where the natural
flow of water that goes to the outlet (tap,
shower etc.) is less than 2 L/min on either
hot, cold or both. This can happen when the
outlet, or the pipework to the outlet, is close
to or above the height of the base of the cold
water cistern. Most instances of negative head
systems occur in loft conversions or where
the cold water cistern sits on the joists in the
loft. If the distance between the bottom of the
cold water cistern and the highest point of the
system after the pump is 2 feet (610mm) or
less, it is also possible that a universal pump
will be required. Salamander’s universal range
of pumps activates the pump automatically
even where no natural flow exists.
Negative head is also needed for electric
showers, dishwashers, washing machines or
where pumped hot water meets mains cold.
Non-Return Valves
Non-return valves MUST NOT be fitted in the
discharge pipework between the pump outlets
and the system outlets unless specified by
Salamander Pumps
Pressure Vessel
BEFORE INSTALLATION OF YOUR NEGATIVE
HEAD PUMP - Fit the pressure vessel, if
packaged separate to the pump. Use the 1/2”
flat rubber washer in the 1/2” brass connection
on the top of the pump junction box. Screw the
pressure vessel into the connection hand tight.

Commissioning
Before you finish
FOR RIGHT PUMP UNIVERSALS, ENSURE
THAT THE PRESSURE VESSEL IS FITTED TO
THE BRASS CONNECTION ONTHE TOP OF
THE PUMP WITH THE ½” RUBBER WASHER
AND IS HAND TIGHT.
• Flush inlet pipework and carefully fill
pump with water by discharging water
from the outlet flexible coupler into a
container.
• Fit pump inlet filters.
It is CRITICAL to discharge water through
the pump into a container using natural flow
before connecting the pump to outlet pipework
in order to ensure the air has been discharged
from inlet pipework and pump chambers.
This will not happen if the outlet pipework is
connected to the pump. The best method is:-
• Connect discharge pipework.
• Check that all the pump isolating valves
are open.
• Fill system. Check for leaks.
• DO NOT RUN PUMP DRY – to do so will
cause irreparable damage to your pump
and will invalidate your warranty.
• Open shower mixer valve/system outlets
to maximum hot and cold to check the
natural flow (unpumped) flow of at least
2 litre per minute, individually on hot or
cold– positive head systems.
• Open hot water outlets fully for 5 to 6
seconds and then turn outlets off. Then
open cold water outlets fully for 5 to 6
seconds and turn outlets off. If flow is
poor and inconsistent repeat above steps
until flow is steady.
• Repeat 2-3 times.

Guidelines -
Cold Water Supplies and
Storage
Aeration of pump and
cylinder from a cold water
storage tank
This occurs when the incoming cold mains ball
valve is positioned above the cold feeds to the
cylinder and to the pump – aerated water is
drawn into the pump as illustrated.
Figure 15: Aeration
Chronic aeration of the pump occurs when this
problem is combined with inadequate storage
capacity and/or when the volume of water
drawn by the pump and other services exceeds
the refill rate and creates a vortex which draws
air and possibly debris into the pump.
Cold storage usable capacity
The usable capacity of cold storage is easily
calculated as the capacity of water in the cold
tank above the cold feeds to the cylinder, the
pump and other outlets – see formula.
Formula for calculation on
rectangular tank:
Depth (15”) x width (23”) x length (36”)
= 12,420 cu inches
Volume cu inches (12,420) x 0.01639
= 203.56 litres
Volume litres (203.56) x 0.22
= 44.78 gallons.
Formula for calculation on
circular tank:
Depth (15”) x radius (17”) x radius (17”)
x 3.142 (Pi)
= 13,621 cu inches
Volume cu inches (13,621) x 0.01639
= 223 litres
Volume litres (223) x 0.22
= 49 gallons.

Water Starvation Protection,
Pipework Arrangements and
Stored Hot Water
Water starvation protection
In systems where it is absolutely not possible
to increase the usable cold water storage
capacity to meet the increased demand of a
pumped system; a water starvation protection
unit (WSP) may be considered.
The WSP is a Salamander level switch which
must be positioned 102mm higher than the
highest outlet from the cold water storage
tank. When the water level drops too far the
WSP will switch off the pump until the cold
water storage level is recovered.
Figure 18: Water starvation protection unit
(WSP)
Shower head size and
Pressure
The size of a shower head dictates the bar
pressure of the pump required to deliver the
expected performance of the shower.
Shower head diameter Bar pressure
Up to 75mm 1.5 bar (150 kPA)
75 -125mm 2.0 bar (200 kPA)

Figure 19: Anti-gravity loop (AGL)
Combi boilers and water
heaters
As these appliances are invariably supplied
directly from the cold mains – they are not
normally suitable for booster pumps. The
exceptions are featured on Page 11. However,
more suitable alternatives may be found in the
Salamander MainsBooster Range.
Figure 20: Combi boilers
Horizontal cylinders
As horizontal (torpedo) cylinders are
problematic for boosted systems consult
PumpWise for guidance and correct use of an
approved top entry flange.
Figure 21: Horizontal cylinders
Approved flanges (cylinders)
The 22mm No Stop Essex and the other
approved top entry flanges with extension
pipes into the cylinder represent the best
known means of ensuring minimal aeration of
the hot supply water to the pump. The No Stop
Essex flange is in all circumstances the best
option.

Warix flange see Figure 23
A. The Vent connection MUST be from side in
Warix Flange.
B. The supply connection to the pump MUST
BE FROM THETOP of the Warix Flange via a
22mm compression elbow and thereby avoid
inverted loops.
C. In systems where there are one bathroom
and an en-suite shower. Or two or more
bathrooms the cold feed to the cylinder should
ideally be in 28mm pipework.
Figure 23: Warix Flange
Inverted loops
An inverted loop in the supply pipe-work
to the pump, particularly on the hot side as
illustrated; is likely to:
• Interfere with the initiation and smooth
operation of the pump.
• Restrict the supply water to the pump and
risk internal mechanical damage
Figure 24: Inverted loops
Water hammer protection
Water hammer most commonly occurs in
systems where there are long pipe runs
supplying solenoid activated appliances
e.g. washing machines or outlets with quick
acting/turn taps/ valve(s).The harmful
effect of water hammer shock waves can be
cushioned by fitting a pressure vessel unit,
into the supply pipework as close as possible
to the outlet from which the shock waves are
originating.
Figure 25: Water hammer protection
Pressure vessel

18
Pump hunting protection
In negative head systems all the discharge
pipework after the pump is pressurised. In
such systems there exists the possibility the
pump will hunt ON-OFF-ON etc. at intervals.
This will happen:
• If all outlets are not fully closed
• If there is a leak at a connection
• If boosted toilets are not fitted with
equilibrium ball valves
• Or as residual hot water contracts in long
pipe runs.
The irritating effects of hunting are cushioned
by the pressure vessel which is an inbuilt
feature of the Right pump universal range.
Stored hot water volume
In calculating the volume of the stored hot
water requirement it is important to consider:
• Number of bathrooms, with particular
attention to the size of the bath
• Number of persons in household
• Time spent in shower e.g. 10mins in
a 5 gall/minute shower will use up 50
galls/227 Litres of the cold water storage
capacity approx 60% of which (30
gallons/136 Litres) will be hot water from
the cylinder.
Stored hot water
temperature
Extract from BS5546:2010 (Current)
“The mean temperature of the stored water
should not normally exceed 60°C and in a
combined central heating and domestic
hot water system it is recommended that
the stored water temperature is controlled
independently from that on the primary
circuit”.
Effective control of stored hot water is simply
achieved by use of a cylinder thermostat and
zone valve or direct acting thermostatic valve
(e.g. tapstat).
In systems where the stored hot water
temperature is not controlled eg Aga solid
fuel appliance or very crudely by the boiler
thermostat, use a HWS Blending valve
controller.
HWS Blending valve
controller
The HWS Blending valve controller is designed
to protect booster pumps in systems where
the temperature of the stored hot water is
uncontrolled. (Figure 17, P14)
