OZELOCK AUTOMATIC WATERING

INSTALLATION & OPERATING

INSTRUCTIONS

1. HOZELOCK PARTS

- Tap

- Pipeline

Drippers

Only the items marked * are supplied

with this kit. All the parts are available

eparately. The components fall into

three groups (A,B,C).

mportant: Measure the site and plan on

paper before cutting/piercing any tube.

Many systems combine supply tube and

icro tube, but each can be used

exclusively.

. MAIN USES FOR THE PARTS:

- Tap

• Pressure regulator (2760) Connects the

utomatic watering system to the tap,

reduces the water pressure for

optimum performance of the system.

• Water Computer (2700) Optional,

battery powered, attaches to the

outside tap, turns the water on and off,

programmed to water your plants

when you are away.

- Pipeline

• Supply tube (2763 – 10m, 2764 – 25m)

Large 13mm tube used to transport

water around medium to large systems.

Make the network using Elbows (2766),

T Pieces (2767), Straight Connectors

(2768) and End Caps (2769). Secure in

place using Stakes (2770) & Wall clips

(2771). Use Flow Control Valve (2765) to

vary the flow & isolate parts of the

circuit.

Note: No one length of supply tube

should be more than 50m from the

pressure reducer

• Micro tube (2772 – 10m, 2773 – 25m)

Small 4mm tube used to transport

water around small systems or to take

water from the supply tube to the

plants in larger systems. Connect to the

supply tube using a Tube Adaptor

(2778), split the flow using T-Piece

(2777). Secure in place using Stakes

(2781) & Wall clips (2782). Use Flow

Control Valve (2776) to vary the flow.

Note: No one length of micro tube

should be more than 15m long.

• Hole Punch (2799) – Use to make holes

in the supply tube for accessories and

for joints with the micro tube. Use

hexagonal slot in the back of the hole

punch to tighten the micro jets into the

tube (and remove them).

Seal unwanted holes with Blanking

Plugs (2779).

- Drippers

• Fixed Rate Drippers (2783) – give drips

of water at a maximum rate of 4 L/H to

suit smaller plants and containers.

Use either on end of 4mm tube or fit

directly to 13mm hose.

• Pressure Compensating Drippers

(

2784/2785) – automatically compensate

to give drips of water at a rate of 4 L/H

- perfect for containers and hanging

askets, can also be used with hedges

and borders.

se 2784 in line on 4mm hose.

Use 2785 either end of line on 4mm

ose, or fit directly to 13mm hose.

•

Adjustable Sprinklers (2786,2787,2788)

– Adjustable mini sprinklers give a 360

degree spray, that can be adjusted to a

ax flow of 40 L/H. Suits large

individual plants and containers.

se 2786 in line on 4mm hose.

se 2787 either end of line on 4mm

hose, or fit directly to 13mm hose.

f using on end of 4mm hose, secure

with a 4mm stake (2781).

se 2788 end of line on 4mm hose.

•

Microjets

(2790,2791,2792,2793,2794,2795,2796) –

Produce a spray of water for complete

overage of flowerbeds with a

maximum range of 2m (diameter).

2793 & 2794 & 2795 supplied with flow

ontrol.

• Mister (2797) – Produces a fine mist to

water delicate plants or provide cooling

or increase humidity - ideal for green-

houses

• 360º Mini Sprinkler – Produces a spray

of water for complete coverage of

flowerbeds with a maximum range of

6m (diameter). Supplied with flow

control.

All micro jets should be overlapped to

avoid a dry patch beneath each

sprinkler.

All Micro jets can be fitted directly to

the supply tube for low level watering,

or can be raised up to 35cm by

combining with the High Spike (2789).

3. INSTALLING THE SYSTEM:

3.1 Connect to the tap using one of the

methods below:

a). Screw the Pressure Regulator (2760)

directly onto the outside tap.

b). Screw the Pressure Regulator (2760)

onto a water computer already fitted

to the outside tap.

c). Connect the Pressure Regulator

(2760) to an Accessory Adaptor (2289)

and snap onto a Hose End Connector

(2166) fitted to a length of hose

attached to a tap.

3.2 Connect pressure regulator to the

hose using one of the methods

below:

a). 4mm tube - use 4mm adaptor

(2760 a) and push 4mm tube through

centre

b). 13mm tube - use 13mm adaptor

(2760 b) and fit 13mm hose.

3.3 Create the network & fit drippers

a). Lay out the supply tube and/or micro

tube around the area to be watered.

The tube will be more manageable if

it is immersed in hot water or

warmed in sunshine prior to use.

Initially position it with weights until

it relaxes.

b). Cut the supply tube and/or micro

tube using scissors and create the

etwork using the required fittings

(Elbows, T pieces, End Caps). Micro

tube can be connected to supply tube

sing (2778) Straight Connectors.

c). Position flow control valves to isolate

reas and improve control of the

system if required.

). Fit drippers either directly to the

supply tube or to the end of the

icro tube.

e). Secure the system in place using

takes and wall clips.

Occasional slight leakage can occur from

he supply tube/micro tube connection

point. This usually seals over time, but

ensure the fitting is correctly inserted at

90º angle.

. CALCULATING THE CAPACITY OF THE

SYSTEM:

f fitting a large system, calculate the

flow from the supply, and therefore how

many accessories the flow will support:

4.1 Using a pressure regulator with the

tap fully on, time in seconds how

ong it will take to fill a bucket of

known volume in litres.

4.2 Multiply the number of litres in your

bucket by 3600, and divide by the

number of seconds it took to fill. This

will give you your maximum flow

rate per hour.

4.3 Each dripper has a given flow rate,

the total water requirement of all the

drippers that you use added together

should not exceed the maximum flow

rate.

E.g.:

a). A 9 litre bucket is filled in 15 secs.

b). 9 litres x 3600 = 42400

c). 42400/15 seconds = 2160

Micro jets use 55 L/H therefore with a

maximum flow of 2160 the maximum

number usable would be 39 (2160/55)

For the flow rate of the Hozelock range

of drippers see inside front cover of this

leaflet or check the individual packaging.

If more drippers are required than the

maximum flow permits, separate the

system into sections that can be run at

different times. If you wish to automate

this you will need more than one water

computer.

5. MAINTENANCE:

At the end of the season, open all flow

control valves and remove end sleeves.

Flush with water to clean, and then drain

to avoid frost damage. Remove the

pressure regulator and water computer

and store away from frost. All drippers

may be dismantled for cleaning. Soak in

an equal mixture of vinegar and water

to remove any residues.
