INSTALLATION
1. YOUR HENDEN MEDIA FILTER
Congratulations on your purchase of a quality product
from the Henden range of pool and spa equipment.
You are assured of many years of reliable and efficient
performance from your Henden Media Filter backed by
Henden’s Ten Year Tank Guarantee and Three Year Valve
Guarantee.*
*Refer to guarantee statement on page 9 for full details.
Henden Media Filters have been specifically designed for
the filtration of swimming pool water in conditions set
out in the Australian Standard for swimming pool water
quality (AS 3633) or equivalent. They should not be used
for any other purpose without first consulting Henden or
your local Reece Irrigation & Pools branch.
2. THE WATER DIFFERENCE
Media filtration is nature’s proven method of filtration.
Pool water enters the filter and passes through graded
media where the suspended particles are trapped and
the water is returned to the pool. As the build up of
dirt in the media increases, the flow decreases and the
water pressure rises. When the pressure reaches an
unacceptable level, the flow must be reversed to clean the
filter media bed in a process called “backwashing”. This
process discharges the dirt to waste.
3. INSTALLATION LOCATION
The filter should be placed in its permanent location,
preferably as close to the pool as possible. Position the
filter tank and pump on a level concrete slab or similar
base with minimum dimensions of 900mm x 600mm
(3’ x 2’). Do not use sand to level the concrete slab, as
it may wash away and cause vibration and inefficient
performance. Allow sufficient space around the filter for:
• routine maintenance
• adequate filter drainage
• pump ventilation
Place the pump in position on the slab and locate the
filter tank alongside with the multiport valve “pump”
port oriented towards the pump.
A minimum clearance of 400mm above the multiport
valve is required to permit easy removal.

HENDEN INSTALLATION & OWNERS MANUAL |5
4. WEATHER PROTECTION
Henden Media Filter tanks are made from UV stabilised
materials. However to ensure years of reliable service,
it is recommended that every effort be made to ensure
the filtration system is adequately protected from the
weather. For proper care and maintenance of your filter,
see the section on “Filter Care”.
4.1 Assembly
1. Look inside the tank and ensure the laterals are secure
inside the hub assembly and that the stand pipe has the
o-ring inserted correctly.
2. Half fill the tank with water to provide a cushion for the
media.
3. Make certain the under drain assembly is correctly
located onto it’s stand at the base of the tank.
4. Place the sand or media guide in the top of the
filter opening.
5. Pour the correct amount of media into the tank (refer
section 10 - Technical Data), evenly distributing it around
the central pipe. Level out the top of the media bed.
6. Remove the sand or media guide and all traces of
media from the tank flange.
7. Ensure the closure o-ring is clean and in the correct
position. If necessary, apply a thin film of o-ring lubricant
to the o-ring. Assemble the multiport valve to the tank
aligning the ports to the appropriate plumbing.
8. Apply Teflon tape to the thread on the pressure gauge
and barrel unions and screw into the multiport valve
body. 7 turns of tape are required.
CAUTION
• A non return valve is required in
between the pump and filter.
• On installations where the waste line
is more than 3 metres below pool
water level and more than 12 metres
in length, a vacuum break valve must
be fitted in the waste line close to
the filter.
• If an auxiliary pump is installed
in line downstream of the filter, it
should be protected against causing
negative pressure in the filter tank.
A flow or pressure switch which only
enables the auxiliary pump to run
when the main filter pump is running
will achieve this.
• If the pump and filter are located
below pool water level, it is
necessary to fit isolating valves in
the pipe between the pump and the
skimmer box and in the return pipe
from the multiport valve to the pool.
This prevents water draining from
the pool during maintenance.
FAILURE TO COMPLY WITH THE ABOVE
CAUTIONS MAY RESULT IN FILTER
DAMAGE NOT COVERED BY THE
GUARANTEE.
5 . PIPE CONNECTIONS
Use Teflon tape on all male threads. Piping should be
independently supported and not impose heavy loads on
the filter or pump. Using the multiport valve as a guide,
use 40mm or 50mm (1 ½” or 2”) pipe:
• from the pump to the skimmer box
• for the return pipe to the multiport valve
• from the multiport valve to the drain
DO NOT OVERTIGHTEN
The fittings and multiport valve
on this product are constructed of
ABS. Some PVC jointing compounds
are incompatible with ABS. Check
compound suitability before use.
50mm pipe must be used with the HMF2550 and
HMF2850 or if the length of piping is over 15m. 50mm
barrel unions are provided at the multiport valve for
connection of PVC pipe to “pump,” “pool return” and
“waste”.
6. COMMISSIONING FILTER
Refer to section 7 - Operating Instructions for safety
warning and multiport valve control prior to the
filter start-up.
The pool should be slightly overfilled, the filter
backwashed and then run on rinse to prevent dust and
fine particles in the media bed returning to the pool.
To do this:
1. Postion multiport valve handle to backwash.
2. Backwash the filter, then stop the pump.
3. Position the valve handle to rinse.
4. Start the pump and run until the water in the valve
sight glass becomes clear.
5. Stop the pump and position the valve handle to filter.
6. Start the pump. The filter is now in filtration mode.
To determine the correct operating conditions, check the
pressure gauge reading is 80kPa or below. Record the
clean operating pressure of your filter.
NOTE Always read these instructions
in conjunction with your media bag
instructions.

7. OPERATING INSTRUCTIONS
7.1 Multiport Valve Control
The flow of water through the filter is controlled by the
multiport valve on the top of the filter tank. The handle on
top of the valve can be moved to any one of six positions,
which have the following functions:
Valve Position Function
FILTER Normal filtration and
vacuuming through filter.
BACKWASH Clean the filter.
RINSE Used on initial filter start-up
and after backwash to prevent
dirt in the sand returning to
the pool.
WASTE By-passes the filter; used
for vacuuming to waste, or
draining the pool.
RECIRCULATE By-passes the filter to
circulating water to the pool or
to boost spa jets.
CLOSED Shuts off all flow to the filter.
Do not run pump.
CAUTION Never shift the valve handle
position while the pump is running.
This filter tank must not be operated
under vacuum. Should leaf baskets or
suction lines become clogged, blocked
or closed, filter damage not covered by
guarantee may occur (particularly if an
auxiliary pump is installed in line down
stream of the filter). Never vacuum
while backwashing.
8. NORMAL FILTER CYCLE
1. Set the valve to filter and start the pump.
2. With a clean filter, record the pressure gauge reading
or mark the needle position on the pressure gauge.
3. Operate the filter each day for a sufficient time to turn
over the water in the pool once every day. The filter
should also be operated at all times the pool is in use
and for about one hour afterwards. During the winter,
the running time may be reduced.
4. When the pressure gauge reading is 40 – 50kPa higher
than the clean filter gauge reading as in (2) above, it
will be necessary to clean or backwash the filter (refer
to section 9 - Backwashing the Filter).
9. BACKWASHING THE FILTER
When the filter gauge reading is 40 - 50kPa above the
clean filter gauge reading, cleaning or backwashing is
required. To perform the backwash operation:
1. Shut off the pump. Be sure to disconnect any automatic
vacuum cleaner.
2. Shift the valve handle to backwash.
3. Start the pump and run until the water appears clean
through the sight glass (this will take two or three
minutes).
4. Shut off the pump and turn the valve handle to rinse.
5. Start the pump and run for approximately one minute.
6. Shut off the pump and turn the valve handle to filter.
7. Start the pump; a new filter cycle has now begun.
8. If a backwash cycle does not reduce the operating
pressure of the filter, the media will need to be
changed.
WARNING - FILTER OPERATES
UNDER HIGH PRESSURE
Ensure all lids / closures / clamps
are correctly secured before operating
the system.
Never adjust clamps or change
valve settings with the system
under pressure.
Relieve all pressure from system
before working on filter.

11. FILTER CARE
The Henden media filter is the heart of the pool
equipment installation. Proper care and maintenance will
add many years of service and enjoyment to your pool.
Keep the exterior of the filter clean, using a mild detergent
and water.
12. WATER QUALITY
Maintaining balanced water chemistry is important to the
life of your pool equipment. This filter is designed to be
used with pool & spa water, balanced in accordance with
Langlier Saturation Index, with a pH level of between 7.2
and 7.6 and is regularly treated with a chlorine sanitising
agent with the level not exceeding 3 parts per million of
free chlorine.
Please consult your local Reece Irrigation & Pools branch
regularly to have your water tested.
13. TROUBLE SHOOTING
Problem Action
Reduced flow of
water into pool.
Check filter pressure gauge. If
40-50kPa above clean filter
reading, perform backwash (page
6).
Reduced
flow after
backwashing.
Check for blocked or plugged
lines which could restrict flow.
Large quantities
of media
returning to the
pool.
One of the lower laterals may
be damaged. To correct this
condition, the media must
be removed and the lateral
replaced.
Pump is
operating noisily.
Investigate for a possible air leak
in the suction line, blocked pipes
or rubbish in the pump strainer
basket. (Refer to pump manual)
Media Filter is
operating noisily
Water flow through the media
filter (and multiport valve) is
too high
The level of media in the filter
may be too high. Refer to
recommended fill line
The media in the filter may not
be level. Media in the filter needs
to be level at the fill line.
In the event of installation or operation difficulties with
your product, contact the installer of the product or your
local Reece Irrigation & Pools branch.
For assistance in locating your nearest branch contact:
reece.com.au/storefinder.
NOTE At the time of filling the tank an
adjustment to the media quantity may
be required. It is recommended that the
media does not exceed the imaginary
dashed line as shown on the diagram.
Insufficient media will:
• affect filtration performance and
require more frequent backwashing
Too much media will lead to:
• media returning to the pool
after backwashing
• media stuck in the multiport valve
causing the handle to jam
• increase in pressure which will
reduce the lifespan of the filter
• noise in the multiport valve
If in doubt, less is better than more.
