1 IMPORTANT FACTS: READ BEFORE COMMENCING PUMP INSTALLATION

A Water storage capacity.

1.11 The water storage capacity must be sufficient to meet the flow rates required

by the pumped equipment and any other water using fittings and appliances,

which may be operated simultaneously. DO NOT RUN PUMP DRY.

1.12 Ensure the pump is primed as described in the priming section before

starting, damage to the shaft seal will result otherwise. See Section 4 –

Plumbing.

B Water temperature

The water entering the pump must be controlled as follows:

1.13 The maximum allowable water temperature is 65 oC.

1.14 The minimum allowable water temperature is 4 oC.

1.15 Ambient temperature: The pump must be sited in a location where the

maximum ambient temperature does not exceed 50 oC (55 oC CH 4–50 only).

1.16 DO NOT fit a pump if the hot water is heated via a method whereby the water

temperature cannot be controlled, such as solar or solid fuel you must consult

the TechAssist team on +44 (0) 800 31 969 80.

C Pipework – general

1.17 Pipework design: Care should be taken in the design of pipework runs to

minimize the risk of air locks e.g. use drawn bends rather than 90obends.

1.18 DO NOT allow contact with oil or cellulose based paints, paint thinners

or strippers, acid based descalents or aggressive cleaning agents.

D Plumbing installation regulations

1.19 The plumbing installation must be installed by a qualified person and in

accordance with local regulations.

E Electrical/installation regulations

1.20 Check the mains voltage and frequency corresponds to the values on the

pump rating plate.

2 LOCATION  GENERAL

2.11 Access: For emergencies and maintenance the pump must be

easily accessible.

2.12 Protection: The pump must be located in a dry position, frost free

and protected from freezing.

2.13 Ventilation: Ensure an adequate air flow to cool the pump.

Separate the pump from other appliances that generate heat. An

80 mm (3 “) air gap must be maintained around the pump.

2.14 Safety: The motor casing can become very hot under normal

operating conditions. Care must be taken to ensure it cannot be

touched during operation.

2.15 Water retention: Site the pump in a location where in the unlikely

event of a water leak, any spillage is contained or routed to avoid

electrics or areas sensitive to water damage.

2.16 Pump position: The pump must be positioned on its mounting feet and as

close to the water source as possible.

2.17 Mounting foot securing: This pump is fitted with cast feet. If there is a

requirement to secure the pump via the feet, the following points should be

noted.

The pump should be mounted on a horizontal surface only, with the outlet

facing vertically upwards.

The mounting bolts used to secure the pump must be fitted with a plain

washer to distribute clamping load evenly across load bearing face of foot

(not supplied).

3 ELECTRICAL INSTALLATION  EARTHING

3.11 Regulations: The electrical installation must be carried out in

accordance with the current local regulations by a qualified person.

3.12 Safety: In the interests of electrical safety a 30 mA residual current

device (R.C.D. not supplied) should be installed in the supply circuit.

This may be part of a consumer unit or a separate unit.

3.13 Before starting work on the electrical supply ensure power supply is

isolated.

3.14 DO NOT allow the supply cord to contact hot surfaces, including the

motor shell, pump body or pipework. The cord should be safely

routed and secured by cable clips.

3.15 Earthing: This appliance must be earthed via the supply cord, which must be

correctly connected to the earth point located in the terminal box.

3.16 Connections: The pump must be permanently connected to the fixed wiring

of the mains supply using the factory fitted supply cord, via a dedicated

double pole switched fused spur off the ring main.

3.17 Wiring of connection unit:

WARNING: This appliance must be earthed.

The wires in the mains lead (supply cord) are coloured in accordance with the

following code:

Green and Yellow: Earth

Blue: Neutral

Brown: Live

As the colours of the wires in the mains lead of this appliance may not

correspond with the coloured markings identifying the terminals in your

connection unit proceed as follows:

zThe wire which is coloured green and yellow must be connected to the

terminal in the connection unit which is marked with the letter E or by the

earth symbol: or coloured green or green and yellow.

zThe wire which is coloured blue must be connected to the terminal which

is marked with the letter N or coloured black.

zThe wire which is coloured brown must be connected to the terminal

which is marked with the letter L or coloured red.

3.18 Wiring diagram:

Fig. 5

3.19 Fuse: CH 4–30, 40, 50 use a 13 Amp fuse, CH 4–60 should use a 16 Amp fuse.

3.20 Supply cord replacement:

The internal wiring within the terminal box is routed and secured

to ensure compliance with the electrical standard IEC 60335–1. It

is essential that prior to any disturbance of this internal wiring, all

cable routing and securing details are carefully noted to ensure re-

assembly to the same factory pattern is always maintained.

3.21 If the supply cord is to be changed or damaged, it must be replaced by a

special cord available from Stuart Turner or one of its approved repairers.

3.22 Cable Gland Fitting Instructions:

To enable correct assembly of the cable gland the

‘O’-ring (Fig. 5 item 1) must be placed over the cable

before the clamping insert (Fig. 5 item 2) can be

tightened.

Note: Cable diameter range:- 9.2 mm to 11.9 mm.

3.23 Supply Cord Extension:

The pumps are fitted with a supply cord to the

following specification:-

All models ..............HO7RN-F3 G 1.5 mm – 10 Amp rated cable.

If the supply cord is to be extended, a cord of the same specification should

be used. Any connections or junction boxes used should be specifically

suited for the application and installed in accordance with the manufacturers

instructions.

We recommend the use of a footvalve and strainer when a suction lift is

required, to reduce priming time.

4.14 System flushing: The pipework system should be flushed out

prior to the pump being connected to ensure any contaminants/

chemical residues and foreign bodies are removed from elsewhere

in the system.

4.15 Priming:

Never operate pump with inlet and/or outlet isolating valves in the

closed position. Damage will occur!

The pump must be primed (filled with water) before starting.

4.16 Turn on the isolating valves.

(a) Loosen vent plug and allow an even flow of water this may take a

few seconds.

(b) Re-seal vent plug, nipping tight.

The pump is now ready to start.

4 PLUMBING

4.11 Pipework: For optimum performance pipework use 28 mm dia., 22 mm can be

used but will result in reduced pump performance.

4.12 Isolating valves: Separate isolating valves (non restrictive) must be fitted to

allow easy pump service.

4.13 This pump has a self priming ability once filled with water. It can therefore be

used to draw water from a storage tank either above or below the pump

position.

switch off and repeat priming process.

4.17 Maintenance:

This product is maintenance free for its life, however it is a mechanical

product and will eventually show signs of wear. Spare parts are available, for

more information phone the Stuart Turner TechAssist team on
