Step 1: Pump location
1. Site the pump in a location where it will not freeze or be exposed to frost during cold weather.
2. Ensure adequate airflow to cool the motor. Separate the pump from other appliances that
generate heat. Install the pump in a clear space allowing 100mm at each side, end and top.
3. Care must be taken not to endanger pre-existing electrics when siting your Salamander pump
4. Ensure the pump is as close to the hot water cylinder as possible & no more than 5m in
measured pipework away.
5. Mount the pump upright (shaft horizontal, not screwed down).
6. An anti-gravity loop (Figure 4) off a NO STOP ESSEX flange MUST be fitted to all systems
where the pump is mounted above the hot outlet from the cylinder.
7. 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 figure 5)
The pump should be installed in accordance with BS7671:2008, it should also be noted
that BS7671:2008 is a guide.
In BS7671:2008 rooms containing baths or showers should be broken down into zones.
These zones are summarised as:
ZONE 0 – This is the bath or shower tray
ZONE 1 – Is considered to be the area where the individual is bathing or showering
or the area where shower water is likely to be directly sprayed.
ZONE 2 – Is the area beyond Zone 1, extending by a further 600mm.
Please refer to BS7671:2008 for further guidance.
8. Check the marker arrows on the pump to ensure correct direction of water flow.
Either end of the pump is suitable for hot or cold water.
9. Check the static inlet pressure does not exceed 10m max (1.0bar/100kPa) of water
above the pump.

10. The hot supply pipework to the pump should be a maximum length of 5 metres in 22mm
pipe (hot and cold supplies should be no more than 2 metres in 15mm pipe).
11. Exclusive hot and cold supplies to the pump with the hot from a Salamander approved
method. Exceptions, only when pump is at the base of the cylinder or within 5m, are:
• hot supply–from the vent angled at 45º, vertically down the hot connection at the vent,
at least 1.5 metres below the base of the cold water storage cistern (Figure 6).
• alternatively, the hot and cold supplies to the pump can be teed off other 22/28mm
supplies (Figure 7) provided that:
• the tee off to the pump is first call on the downward leg after the vent connection.
• the cold supply to the pump is not shared with the cold feed to the cylinder.
12. The best hot connection from the cylinder (figure 3) is either with:
a ¾inch no stop Essex flange, or a Salamander S flange or other approved top entry flange
is fitted.
13. If pump is fitted above cylinder, a No Stop Essex flange must be used.
14. Check that water storage capacity recovery meets required flow rates, particularly at peak
demand (i.e. appliances in simultaneous use).
15. All up and over pipework must be vented at the highest point on the outlet of the pump.
16. Ensure that pipe runs minimise airlocks.
17. In positive head systems, allow for increased resistance of long pipe runs with multiple
bends. The natural flow from the shower head or other outlets must be at least
2litres/minute at all times. Any supply where the natural flow is less than 2litres/minute
is classed as a negative head situation.

Negative head systems exist where no natural flow of water goes to the outlet because either
the outlet or the pipework to the outlet are 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 in 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 activate
the pump automatically even where no natural flow exists.
UK CT pumps suitable for negative head operation are:
CT FORCE 15 TU, 20 TU, 20 SU, 30 TU and 30 SU, and CT Bathroom 60BU, 80BU & 90BU.
Irish CT pumps suitable for negative head operation are:
CT FORCE 15 ITU, 20 ITU, 20 ISU, 30 ITU and 30 ISU, and CT Xtra 64HU, 69HU, 84HU & 94HU.

Commissioning
Before you finish
Fit pump inlet filters and vibration dampening feet.
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, not outlet pipes.
•Check that all the AV coupler 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) MUST be at least 1 litre in 30 seconds per side and 2 litres in 30 seconds mixed.
• 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
The hot connection must be via an
approved side or top entry flange

Step 2: Connecting the pump
Use only Salamander supplied AV couplers to connect the pump.
All associated pipework MUST be thoroughly flushed before making final connections
to the pump. Fill the pump with water before connecting to the discharge pipework.
The in-line strainers must be fitted to the hot and cold inlet supplies to the pump.
A Hose to pipework
The anti-vibration coupler nuts need
only be finger tight plus one quarter turn.
Mechanical tools must not be used to
tighten plastic coupler nuts as this may
cause damage which will invalidate the
warranty.
B Hose to pump
Do not twist or bend anti-vibration hoses
as this will invalidate the warranty.
Ensure that there are suitable means
of isolation for maintenance
Filter washers MUST be fitted to the inlets of the pump to validate your warranty.
Flat washers must be fitted to the outlets. Flat and filter washers are supplied with
the pump.

Step 3: Electrical installation
Your pump must be connected to the electrical supply using the main cable with the attached
plug. This plug must be connected to an accessible socket that has been installed in compliance
with IET Wiring Regulations.
The Plug must be accessible at all times.
If the supply cord is damaged, it must be replaced by the manufacturer, it’s service agent,
or similarly qualified person in order to avoid a hazard.
All pipe work must be cross-bonded in accordance with the IET Regulations.
The pump is supplied with a fuse fitted. Higher rate fuses MUST NOT be used.
If installed by a Part P qualified installer, the pump may be fitted via a fused mains spur without
invalidating the warranty. See Technical Specifications for fuse ratings for each model of pump.
Ensure that the pump is fully operational before hard wiring pump in this instance, this should
be done during commissioning.

Helpful guidelines
Cold water supplies and storage Recovery of cold storage
Ensure that there is sufficient water recovery to cover the water usage by the appliance
Aeration of pump and cylinder from a cold water storage cistern
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.
Chronic aeration of the pump occurs when
this problem is combined with inadequate
storage capacity and/or when the volume
of water is drawn by the pump and other
services exceeds the refill rate and creates
a vortex which draws air and possibly debris
into the pump.
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 (See fig 11).
The WSP is a Salamander level switch which must be positioned 102mm higher than the highest
outlet from the cold water storage cistern. When the water level drops too far the WSP will
switch off the pump until the cold water storage level is recovered.
Cold storage usable capacity
The usable capacity of cold storage is easily calculated as the capacity of water in the cold cistern
above the cold feeds to the cylinder, the pump and other outlets – see formula.
Formula for calculation on rectangular cistern:
Water above inlet (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

13
Anti-gravity loops
An anti-gravity loop (AGL) must always
be fitted to systems where the pump is
positioned above the dome of the cylinder
(see fig 12). The AGL which limits aeration
of the hot supply to the pump is formed by
bending the pipework downwards for
250mm, as it exits the No Stop Essex flange,
before rising again to the pump.
(See figure 14).
Combi boilers and water heaters
As these appliances are invariably supplied
directly from the cold mains – they are not
suitable for this range of pumps, unless
pumping from a cold water storage cistern
via a universal pump.
Horizontal cylinders
As horizontal (Torpedo) cylinders are problematic for boosted systems consult PumpWise
on 0191 516 2002 for guidance and correct use of an approved top entry flange.
S flange
Complete with compression pump outlet and the open vent connections. Also supplied with

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.
Please contact PumpWise on 0191 516 2002

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.

15
Pump hunting protection
In negative head systems all the discharge pipework after the pump is pressurized.
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.
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
Stored hot water temperature
Extract from BS5546:1990 (Current)
“The mean temperature of the stored water should not normally exceed 60ºC 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”.
Extract from BS6700:1997
“Under normal conditions the temperature of stored hot water should never exceed 65ºC.
A stored hot water temperature of 60ºC is considered sufficient to meet all normal requirements
and will minimise scale deposits in hard water areas”.
Effective control of stored hot water is simply achieved by use of a cylinder thermostat or direct
acting thermostatic valve (e.g. tapstat).
Maximum water temperature for CT Xtra, CT Bathroom & CT FORCE pumps is 60ºC.
In systems where the stored hot water temperature cannot be controlled e.g. Aga solid fuel
appliance or very crudely by the boiler thermostat, a Salamander approved HWS TMV must
be used.
