The AccuBoost unpumped range consists of a pressure vessel and integral base. The
AccuBoost pumped range consists of a pressure vessel and an electrically operated pump
attached to the integral base. The pump control reacts to the mains water pressure and
draws water from the mains. In both cases, the amount of available water in the property is
increased as well as helping to stabilise the pressure.
AccuBoost products are designed to assist the flow and pressure of the mains water supply
within domestic or small commercial applications. The pressure vessel stores mains cold
water at pressure, which is then released into the system to assist the incoming mains water
when an outlet is opened. AccuBoost is ideal for enhancing the performance of combination
boilers, unvented hot water cylinders, electric showers and mixer showers where there is poor
pressure and/or flow.
Unpumped Units
Unpumped units require an incoming mains water static pressure of 2 Bar/200 kPa or above.
The unpumped models will increase the available flow rate by delivering additional flow
from the pressure vessel. Once the water within the vessel has been depleted, the flow will
continue at the natural mains unassisted flow rate.
Pumped Units
For applications where the flow rate and/or the pressure of the incoming mains water is low
(below 12 L/min and/or less than 2 Bar/200 kPa static pressure), the pumped models will
increase the incoming flow rate up to 12 L/min as well as delivering additional flow from the
pressure vessel. Once the water within the vessel has been depleted, the pump will continue
to deliver 12 L/min at a higher pressure than the incoming mains.
Should the natural flow of the incoming mains exceed 12 L/min, the pump is equipped with a
bypass to enable the mains to fulfill more of the demand or refill the vessel.
The pumped units require a minimum unassisted supply of 2 L/min to operate. The pump is
capable of producing a maximum pressure of 4.0 bar (400 kPa) at closed head.

6. Installation Instructions
All AccuBoost models are designed to be connected directly to the cold mains water supply
within the property. Pumped models should ideally be connected directly after the stopcock.
Unpumped AccuBoost units can be located within the building, loft areas, outbuildings,
garages or basements - but the location must be dry and frost free. When locating AccuBoost
the following points should be considered:-
Access & maintenance:
- For maintenance purposes and emergency situations, the AccuBoost unit (and pump if
applicable) and any isolation valves must be easily accessible.
- A clearance of 100mm above the pressure vessel is advised to allow access to the valve
for air precharge pressure checking and adjustment.
- It is advised to fit a water maintenance bypass when installing an AccuBoost unit. This
allows the property to have a water supply available whilst any maintenance is carried out.
See Figures 1-4 on pages 4 & 5 for further details.
6.1 Location
Pipework:
- AccuBoost pumped units should ideally be installed directly after the mains stopcock. Any
outlets before the AccuBoost pumped unit will not benefit from the AccuBoost unit.
- The length of pipework from the incoming main to the AccuBoost unit should be kept as
short as possible. Longer pipe runs may impact on the performance of the unit.
- The isolating valves on the supplied anti-vibration hoses should be accessible once the
unit is installed.
- All pipework must have adequate insulation to protect against frost and freezing.
- On pumped versions the flow direction is clearly marked on the brass end of the pump.
Please refer to Figure 6 on page 9.
Safety:
- During normal operation the casing of the pump can become very hot and may take some
time to cool down. Measures should be taken to ensure it cannot be touched.
- The pump should never be covered so as to stop airflow for ventilation.
- Care should be taken to ensure nothing can fall on or puncture the pressure vessel and
pump.
- The AccuBoost unit is stable in normal operation, however should there be a risk of the unit
being pulled over, additional retaining methods such as a retaining strap should be
installed (not supplied).
- The AccuBoost unit must be installed in a dry location.
- In the unlikely event of a water leak, the AccuBoost unit should be positioned so that water
can be contained or directed away from any electrics or other sensitive areas.
- A pressure reducing valve should be fitted on the installation to ensure that the pressure
does not exceed the safe working limit of the AccuBoost system (8.6 Bar/860 kPa) and to
provide optimised performance.

7
AccuBoost unit thermal protection:
- The AccuBoost has an operating ambient temperature range of 4°C to 49°C.
- If installed in a loft area, garage, outbuilding or any position where temperatures may fall
below 4°C or rise above 49°C thermal protection must be provided.
- There is a possibility that the sun or other appliances that generate heat could warm the
water within the pressure vessel. This should be considered when choosing a location for
the AccuBoost unit.
- The AccuBoost range of products are designed for use with cold mains water only.
- The AccuBoost units are capable of a maximum water temperature of 35°C and a
minimum of 4°C. The cold water should be stored and distributed below 20°C to prevent
Legionella growth.
6.2 Water temperature
Ventilation:
-Ensure adequate airflow to cool the motor. Ideally, leave 100mm air gap around the pump.
- The AccuBoost unit and pump should be positioned away from other appliances that
generate heat.
Loading/support:
- The AccuBoost unit should be installed on a smooth, flat, level surface so that the pressure
vessel is vertical.
- The base of the unit should be fully supported across the entire base to ensure maximum
stability and safe loading. Refer to Figure 5
- The floor/mounting surface must be able to withstand the maximum full weight of the
AccuBoost unit (please refer to the technical specification for the weights of each unit).
Additional supports should be added to the support surface if required.
Figure 5

8
- Once a suitable location has been identified, the unit should be removed from the
packaging and inspected for any damage
- Carefully move the unit into position
- A maintenance bypass containing full bore isolation valves (not supplied) should be
installed to AccuBoost pipework to allow any maintainence to be carried out without
disrupting the mains water supply to the property. See Figures 1-4 on pages 4 & 5.
- For unpumped versions it is advised to install an inline strainer before the AccuBoost unit.
Pumped versions have an inline strainer incorporated into the design of the pump.
- A double check valve and pressure reducing valve (not supplied) must be installed after
the stopcock on both pumped and unpumped installations. See Figures 1-4 on page 4-5.
NOTE: the maximum system pressure of the AccuBoost system is 8.6 Bar/860 kPa. If this
pressure is exceeded irrepairable damage to the unit, serious injury, death or property
damage could occur. This will also invalidate the warranty of the product. Please consider
pressure spikes that can occur and the fact that the mains pressure may vary at different
times of the day/night.
6.4 System connections
6.3 Pipework
General plumbing:
- Ensure pipework runs are as short as possible and minimise potential for airlocks.
- To meet the requirements of the water supply (water fittings) regulations, a type EC-
verifiable double check valve should be fitted. Refer to Figures 1-4 on page 4 & 5.
- Ensure the combined mains pressure and pump pressure does not exceed the maximum
system pressure of 8.6 Bar/860 kPa. A pressure reducing valve (not supplied) should be
used on the incoming mains before the AccuBoost unit.
- All outlets connected between the mains stopcock and AccuBoost unit must be protected
by non-return valves to prevent backflow of water and air into the AccuBoost unit.
- All pipework must be cross-bonded in accordance with IET Regulations.
Secure pipework:
- All pipework to and from the AccuBoost unit should be supported with pipeclips.
Flux:
- Solder joins must be completed and flux residues removed prior to the AccuBoost unit
installation. Solder flux must not come into contact with the presure vessel, pump, base,
anti-vibration hoses or any part of the AccuBoost unit. Flux damage will invalidate any
warranty.
- All associated pipework must be thoroughly flushed before making final connections to
the AccuBoost unit.
Natural water flow:
- A minimum mains water static pressure of 2 Bar/200 kPa is recommended for unpumped
units. Performance and refill times will be improved when the flow rate is higher.
- Pumped versions are usually recomended when the natural flow rate is below 12 L/min or
the mains static pressure is below 2.0 Bar/200 kPa. For pumped units there must be at
least 2 L/min of natural water flow.

9
- Unpumped units use the same pipework to the pressure vessel for both filling and
emptying the vessel. This should be connected to the mains as shown in Figures 1 & 3.
- Pumped units have a seperate inlet and outlet. Arrows on the brass end of the pump
clearly show the inlet and outlet, refer to Figure 6. The included anti vibration hoses should
be used to make the connections between the pipework and AccuBoost unit. The supplied
flat washers should be used when attaching the hoses. The hoses should be finger tight
plus one quarter turn. Do not twist or bend the hoses so that they kink as this will restrict
the flow and also invalidate the warranty.

To maintain optimum performance of the system, a pressure differential of approx. 1.5 Bar
between the mains water static pressure and air precharge pressure within the vessel should
be maintained. The air precharge of the vessel should never be less than 0.5 Bar.
- Pumped units have the air precharge pressure set at the factory to 1.5 Bar/21.75PSI.
This will deliver optimum performance for the pumped units. The actual air precharge
pressure may vary due to storage conditions and the length of time in storage. The air
precharge pressure should be checked and adjusted if necessary.
- Unpumped units require the incoming mains water static pressure (when no outlets are
drawing water) to be measured and the air precharge in the vessel adjusted accordingly.
Refer to the following steps and Table 1.
Checking air precharge pressure:
- Before checking the air precharge pressure of the vessel make sure that the electrical
supply to the pump has been isolated (for pumped versions), the mains water supply to the
unit has been switched off via the stopcock, all water has been emptied from the vessel
and that an outlet such as a tap is left open to allow any residual water to escape.
- Fully unscrew and remove the valve cover located on the top of the pressure vessel to
expose the Schrader air valve.
- Using a tyre pressure gauge, check the air pressure within the vessel.

Valve cover
Schrader

11
Adjusting the air precharge pressure:
- To reduce the air precharge pressure in the vessel, depress the centre of the Schrader
valve to release air pressure. Only release a small amount of pressure at a time and then
the remaining pressure should be checked again. Continue to do this until the correct air
precharge pressure is achieved. If too much pressure is removed, the air pressure must be
increased as per below.
- To increase the air precharge pressure in the vessel, attach a suitable car or bicycle pump
and insert air into the vessel. The pressure should be checked during the process to ensure
the required air pressure is not exceeded.

7. Final Commissioning
- Flush all air from pipework before connecting AccuBoost unit
- Connect AccuBoost unit to pipework
- Close all outlets and ensure isolation valve(s) are open to and from the AccuBoost
- Turn on stopcock to begin filling the vessel
- Turn on the electrical supply to the pump (if applicable). The pump will begin to run to help
fill the vessel
- Open each outlet that is supplied by the AccuBoost system until all air has been expelled
- Close all outlets and allow the vessel to fully fill. The fill time of the vessel depends on
the mains water flow and also the size of the vessel
- The pump (if applicable) will continue to run even when all outlets are closed, until the
vessel is full and the correct system pressure has been reached
- The AccuBoost (including pump if applicable) and all system pipework should be checked
for leaks whilst the vessel is filling, when the vessel is full and while water is being drawn
from an outlet. Any leaks should be rectified and then the checks performed until no leaks
are present.
Note: The pump responds to the pressure within the system. When the system pressure drops
below the pre-programmed level due to an open outlet, it will automatically turn on. If a small
amount of water is drawn from the system that does not allow the pressure to drop below
the pre-programmed level, the pump will not turn on. When outlets are closed the pump will
continue to run until the vessel has filled to the correct pressure.
If you have any queries regarding the installation of AccuBoost please call PumpWise on
0191 516 2002
It is critical to discharge water through the pump into a container using natural flow before
connecting the outlet of the pump to the pipework. This ensures the air has been discharged
from the inlet pipe work and pump chambers. The best method is :-
- Connect the inlet pipework to the inlet anti-vibration hose
- Check that all isolating valves on anti-vibration hoses are open
- Turn on stopcock and allow water to flow from the pump outlet anti-vibration hose into a
suitable container (such as a bucket)
- Turn off the stopcock and connect the pump outlet anti-vibration hose to the pipework
DO NOT RUN PUMP DRY- to do so will cause irrepairable damage to your pump and will
invalidate your warranty

Disconnect electrical supply before working on pump (on pumped versions). Turn off
water supply to the unit, completely empty the vessel of water by opening outlets before
attempting any maintenance.
Cleaning the filters
The inline strainer filter and filter washer (pumped units) should be cleaned at regular
intervals to allow the free flow of water into the system. It is recommended that the filters
are cleaned at least once a year. The filter should be cleaned as follows: -
1. Isolate pump electrically (on pumped versions)
2. Isolate the mains water supply via the stopcock
3. Release system water pressure by opening an outlet (tap) and allow the vessel to
fully empty
4. Unscrew the inline strainer filter cover (some residual water may be released when
cover is unscrewed)
5. Remove the filter and clean out any debris
6. Replace filter and tighten cover, ensuring that the o-ring makes a watertight seal
7. For pumped units, the filter washer on the inlet to the pump should also be cleaned.
Loosen the inlet nut as shown below in Figure 12.
Remove the filter washer and clean out any debris.
Replace the filter washer.
Tighten the nut.
8. Open the mains stopcock and any isolators. Turn on electrical power (on pumped versions)
9. Check for correct operation and ensure there are no leaks in the system

If an unpumped unit has been installed and there is a requirement for a pumped version, a
pump can be retrofitted (Salamander Pumps part code ACC-UPG-KIT), as long as all of the
criteria within this manual are adhered to. IMPORTANT NOTE: ONLY A SALAMANDER PUMPS
ACCUBOOST PUMP (ACC-UPG-KIT) CAN BE RETROFITTED - DO NOT ATTEMPT TO FIT ANY
OTHER PUMP INCLUDING THOSE FROM THE OTHER SALAMANDER PUMPS RANGES. For
more information, please consult PumpWise on 0191 516 2002.
To fit the pump: -
1. Isolate the mains water supply via the stopcock and release system water pressure by
opening a system outlet (tap) and allow the vessel to empty.
2. Remove the brass vessel connector.

3. The brass vessel connector should be checked to ensure that it contains 1x washer, 1x
flow regulator and 2x non-return valves. If the vessel connector does not contain these,
they should be inserted as shown. Correct orientation of the non-return valves and flow
restrictor is crucial for correct operation, refer to Figure 14 below for correct orientation.
The correct flow restrictor for the size of the vessel should be used, please refer to
Table 2 for the correct flow restrictor for the vessel size. A flow restrictor kit is available
from Salamander Pumps, part code FLO-RES-KIT. Reconnect the brass vessel connector to
the vessel.

4. Attach the 4 anti vibration feet to the pump (one per corner). Place a pump retainer
over 2 of the anti vibration feet. Repeat for the other side.
5. Position the pump so that the retainer fixing holes line up with the holes on the vessel
base. Insert the 4x fixings and tighten so that the pump is secure.
6. Connect the straight end of the vessel hose to the vessel port on the pump and connect the
angled end of the vessel hose to the brass vessel connector.
Note: a pumped unit should be installed after the stopcock and before any outlets. Any
outlets between the stopcock and the AccuBoost pump will not benefit from the AccuBoost
unit. If there is not space to install the pump and vessel by the stopcock, the pump can be
installed by the stopcock and the vessel installed elsewhere. Please note, in this scenario
the vessel outlet on the pump must be capped off and the vessel connected to the existing
property pipework. In this scenario, the overall performance of the system may be reduced.
7. Continue to follow the Installation instructions on page 6.

If additional water storage capacity is required, multiple vessels can be installed in a system.
NOTE: ONLY ONE PUMP CAN BE FITTED PER INSTALLATION. Additional vessels should be
connected via a “T” on the vessel port of the pump (for pumped versions). A Salamander
Pumps vessel connector kit (part code TNK-CON-KIT) can be purchased separately to allow
multiple vessels to be connected. The precharge air pressure within all vessels in the system
should be set to the same value.
Please see typical installation examples below: -
