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 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

Pre-installation

Installation

PumpWise guidelines


Trouble shooting


Please follow these installation instructions carefully. Failure to install your pump in accordance with these instructions will invalidate your warranty.

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.

Fig 1

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 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.

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

RSP 50 and RGP 50 are supplied with

15mm couplers with isolating valves on the inlets and outlets.

Figure 4: Isolating valves

2.3 Hot water requirements

The stored hot water temperature must not exceed 60-65ºC (see page 16, 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

• Alternatively a Salamander S flange or other approved top entry flanges. See page 16.

• Never fit to top entry flange if the pump is fitted above the cylinder.

PumpWise guidelines


Trouble shooting


Each single pump is supplied with two couplers; one angled and one straight.

The angled coupler should be attached to the pump inlet (on the side) and the straight coupler should be attached to the pump outlet (on the top).

Each twin pump is supplied with four couplers; two angled and two straight.

For all pumps, the inlets are on the side of the pump and the outlets are on the top of the pump.

The AV couplers MUST only be tightened to finger tight plus one quarter turn.

Mechanical tools must NOT be used to tighten coupler nuts as this may cause damage which will invalidate your warranty.

4 General plumbing

The installation must comply with the relevant requirements or local by-laws.

The pump MUST be mounted upright (shaft horizontal, not screwed down).

Jointing compounds, Boss White, hemp and steel wool MUST NOT be used. Solder fluxes must not come into contact with the pump or the AV couplers.

The maximum static head should be 10m

(equivalent to 1.0 bar pressure) with the exception of the ESP 50 CPV pump where the maximum static head should be 5m

(equivalent to 0.5 bar pressure).

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 BS7671

(I.E.E. 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:

ESP CPV pumps (positive head)

An ESP pump is capable of operating in positive or negative head. Should you need to switch from one to the other please follow the instructions below:

To set the pump in Negative head:

1 Turn off the power to the pump, then turn it back on.

2 The pump will run showing an amber light (L.E.D.) then will stop.

3 Wait until a green light shows on the pump and turn the power off for

5 seconds.

4 Turn the power back on to the pump.

5 The pump will repeat this sequence but do not turn off the pump, at the end of the sequence the green light will flash then go off and then come back on and stay on.

6 The pump has now been set in negative head.

To set the pump in Positive head:

1 Turn off the power to the pump, then turn it back on.

2 The pump will run showing the amber light then will stop – switch it back off immediately.

3 Wait 5 seconds then turn the pump back on.

4 The amber light will come on and go back off again. The green light will come on and go back off again. Finally, the amber light will come back on and will remain on and the pump is now in positive head.

Negative head systems

Negative head systems are those where the shower head or other outlets are above or are level with the cold water storage tank, or when the low head pressure does not provide enough natural flow to the outlet.

Salamander positive head pumps require a natural flow of only 1 litre per 30 seconds per flow switch. Negative head systems are typically loft conversions or flats with showers which have self-contained hot and cold water services. See Figure 10.

Fully automatic negative head systems are best accommodated by using an ESP CPV pump (the fully integrated option which has a built-in pressure vessel and electronic system protection).

The requirements of large systems including multiple body sprays and or boosted supplies to two or more bathrooms are best served with Right ESP CPV Super Booster with integral pressure vessels. See Figures 16, 17 and 18.

ESP CPV

ESP CPV pumps can be commissioned to operate in negative or positive head. The correct procedure for commissioning is therefore extremely important.

Commissioning

Before you finish

• 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:-

Figure 19


MAX

65˚C

• Connect discharge pipework.

• Check that all the pump isolating valves are open.

• Fill system. Check for leaks.

Helpful guidelines

Cold water supplies and storage

• 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

1 litre per minute – positive head systems.

• FOR RIGHT ESP CPV pumps see notes on page 7.

Recovery of cold storage

The typical recovery rate of a 1⁄2 inch high pressure part II BS1212 ball valve is:

15PSI (1.0 bar)

30PSI (2.0 bar)

40PSI (2.7 bar)

60PSI (4.0 bar)

0.97 galls/min

1.34 galls/min

1.58 galls/min

1.94 galls/min

• 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.

Aeration of pump and cylinder from a cold water storage tank

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 –


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

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

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.

Trouble shooting


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 ESP CPV pumps.

Extract from BS6700:1997

“Under normal conditions the temperature of stored hot water should never exceed 65°C. A stored hot water temperature of 60°C 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 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.

Stored hot water volume

HWS Blending valve controller

In calculating the volume of the stored hot water requirement it is important to consider:

The HWS Blending valve controller is

Fig 29 HWS Blending

attention to the size of the bath

• number of persons in household designed to protect booster pumps in systems where the temperature of the stored hot water is uncontrolled – see below.

Figure 33: HWS Blending valve controller to floor mounted pump

• time spent in shower e.g. 10mins in a

5 gall/minute shower will use up 50 galls of the cold water storage capacity approx

60% of which (30 gallons) will be hot water from the cylinder.

Can be off the vent if this distance is at least 1.5 metres

Stored hot water temperature

Extract from BS5546:1990 (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”.
