Door Post Pipe System
Turn the elbow in the overhead spray line so that it
is pointing in the direction of the door post you have
chosen to support the pipe work. Cut a short piece of the
remaining 20mm pipe at a length that spans the distance
between the elbow in the spray line and the centre of the
doorpost. Push a barbed elbow into one end of this joining
pipe and push the opposite end of the pipe onto the
barbed elbow on the spray line (dia.2).
Assemble the Water Inlet System using the remainder
of the 20mm pipe and the parts shown (dia.3). Use 2-3
complete turns in a clockwise direction of PTFE tape to
join the Tap to the Pressure Regulator, see (dia.3 detail).
Hold this assembly up to the door post and decide on a
suitable height for the tap. Cut the Water Inlet System pipe
to match up to the elbow in the joining pipe. (Ensure that
the joining pipe is as close to the horizontal as possible).
Using the pipe clamp screw this to the door post inline
with the joint between the tap and pressure regulator
whilst holding the tap at the required height. Clip the
pressure regulator into the pipe clamp to prevent the
manifold from sliding up and down. Use the nail on pipe
clamps to x the remainder of the Water Inlet System pipe
to the door post.
Spray Nozzles
Tighten the cable ties along the ridge and use the hole
punch to punch a hole approximately in the middle of
a hoop space in the underside see (dia. 4 detail). Insert
a down tube adaptor in each hole using the punch for
assistance. Assemble the down tube and spray nozzle
(dia.4) and insert into each of the adaptors. Note the
direction of ow on the Anti drip valve.

Prestige Overhead Irrigation (if ordered).
If you ordered a Prestige Irrigation System then you will
need to t the Water Controller onto the tap of your water
source. The water controller is supplied with fittings for
either a 3/4in or 1in male threaded tap. Use the two ‘Hose
to Female Click’ ttings to run a hose between the ‘Male
Click’ ttings on the Water Controller and the Polytunnel.
You will require a hose pipe and may require extra ‘Click’
ttings depending on the type of tap being used.
TIP
The Anti Drip Valve used is designed to
prevent the sprayers from dripping when the
water supply is turned off. However, low water
pressure supplies may not close the valve and
so prevent the system form working correctly.
If so these valves can be removed to improve
the effectiveness of the system.
