Overview
The HPX system combines a high-quality self-priming pump, advanced pump control with dual-stage
sediment iltration and ultraviolet water treatment to provide clean, safe pressurised water for your
home. The housing is designed and manufactured in NZ to meet our harshest conditions yet blend
into the landscape and protect your equipment.
Cartridge pre-iltration removes sediment that could reduce ultraviolet (UV) eectiveness and water
clarity.
The incorporated Greenway® UV Advance Series™ ultraviolet technology system is a natural
puriication process that’s completely eco-friendly, chemical-free and kills 99.9% of bacteria,
including E. Coli, Giardia, and Cryptosporidium. This process is critical for untreated water supplies
such as rain tanks, bores or other back up water supplies.
Note: water quality will adversely aect the performance of your UV disinfection system, and the
following levels should be utilised as a guideline for pre-treatment requirements of the inluent water
supply before UV treatment:
• Iron Total iron count must be less than 0.3 ppm (0.3 mg/L)
• Turbidity Count must be less than 1 NTU
• Tannins Count must be less than 0.1 ppm (0.1 mg/L)
• Manganese Count must be less than 0.05 ppm (0.05mg/L)
• Hardness Count must be less than 120 ppm (7 grains per gallon)
• %UVT (transmittance) Must be greater than 75%
The HPX system cartridges and lamp need regularly replacing to maintain optimum performance.
This is a simple procedure when following instructions. For replacements, contact your nearest
Davies Pumps Filtration stockist.
Your new HPX system incorporates a failure warning feature that warns you of a lamp failure by a LED
warning light and an audible alarm. The alarm sounds when the lamp is due to be changed to ensure
eective treatment is maintained. A green LED indicates that the system is operating correctly.
Your HPX will arrive thoroughly tested from the factory and require minimal
installation to save you time and money.

Always use soft gloves or a clean cloth when handling the UV lamps and quartz sleeves to prevent oil
deposits on the surface. Oil deposits from your hands can create hot spots on the surface, leading to
premature bulb failure.
Fit the UV sleeve
• Unscrew the VuCap.
• Remove the UV chamber retaining nut.
• Remove UV sleeve from packaging using a lint-free cloth, slip the O-ring approximately 10mm down
over the open end. Ensuring the sleeve is centrally located, carefully insert the closed end into the
chamber and slide into the central locator at the far end.
• Insert the spring into the sleeve.
• Fit the lower half of the VuCap to the chamber
• Reit and tighten the retainer nut, ensuring the O-ring and sleeve are irmly in place for a
complete seal.
Ultraviolet Sleeve & Lamp Installation
Fit the UV Lamp
• Remove the UV lamp from the packaging with a lint-free cloth.
• Connect the UV lamp plug to the bulb.
• Insert the UV lamp into the sleeve until it rests on the spring.
• Connect the top part of the VuCap over the lamp lead and connect to the lower VuCap part
on the chamber.
• For systems that have not had any prior treatment, lushing the pipework with a suitable
sanitiser is recommended. The sanitiser can be added to the water source or the ilter
housings and allowed to sit overnight before thorough lushing of pipework.

Initial Setup
• Now all plumbing connections are complete, check the ilter housings are tight, the UV
lamp is itted, and the taps are open.
• Prime the pump through the iller port in the pump casing until full.
• Switch the power on at the supply and switch on the pump socket. The pump will run
and leave the discharge open until all the air has purged out and the system is primed.
• Switch on the UV and wait 23 minutes to allow the bulb to heat up.
• Close the discharge valve, and the pressure gauges will rise, and the pump will turn o.
• The system is now ready for normal operation. Open the discharge valve and check the
taps in the house are all working.
Final System Operation
• The recommendation is to leave the UV on at all times to ensure all water is being treated.
Leaving the UV unit on can mean the water in the chamber will heat up when not in use,
and condensation may appear on the UV chamber; this is normal.
• The HPX system is supplied with either the HG3.1 auto controller or the HG8 variable
speed/constant pressure controller. For speciic instructions on adjusting the controllers,
please see pages 30 or 34
• The controller has a digital pressure gauge. There is a second gauge after the iltration
units – this is to show the pressure dierential over the ilters and indicate if they are
blocked (the more signiicant the dierential, the more blocked they are).
• If the system is not going to be used for some time, we recommend switching the power
and taps o to prevent property damage in case of a component failure.
• If there are freezing conditions, the pump, ilters, and UV chamber must be drained of
water to prevent damage.

Cartridge Replacement Procedure
The HPX is itted with a dual 20” cartridge ilter system. The irst ilter (right side) is a
20-micron polyspun cartridge and the second (left side) is a 5-micron polyspun cartridge.
The irst cartridge is to remove large particles, and the second cartridge is to remove smaller
particles which would reduce the UV eectiveness.
The ilter cartridges will require regular replacement to maintain optimum eectiveness.
Replace them 36 monthly or when there is a noticeable pressure drop. The cartridges may
also require lushing or replacement if the system has not been used for a long time.
Caution: Only use genuine replacement cartridges, or potential damage may not be covered
by warranty.
To change the ilter cartridges, please adhere to the following procedure:
• Turn the water supply o using the shut-o valve located inside the HPX unit.
Relieve the pressure by opening a downstream tap or pressing the red pressure-relief
button on the ilter housings.
• Unscrew the ilter bowls. Use the spanner to assist if they are tight. Remove the cartridges
and dispose of them according to local guidelines.
• Clean the bowls with warm water and soap. Check O-rings and replace if damaged. Lightly
lubricate with food-grade lubricant or similar.
• Remove all packaging from new cartridges and install them into the bowls, ensuring they
center on the base location.
• Hold bowls upright while screwing back into the housings. Ensure that the ixture in the
housing heads is located centrally to the cartridges to make a good seal. Tighten the bowls
until irm. HAND TIGHTEN ONLY. DO NOT OVERTIGHTEN.
• Open a downstream tap to allow air to be released and slowly open the water supply
allowing all air to be purged. Let the pump run for 23 minutes to purge air and lush the
system.
• Close the downstream tap and check for leaks.
• Reit the door

UV Lamp Replacement Procedure
During normal operation of the system, the green power LED light will be illuminated, and the
display will indicate the number of days remaining until lamp replacement is required.
The following instructions for general maintenance of the system and UV lamp replacement/
quartz sleeve cleaning or replacement. An accredited service technician must complete all other
system repairs.
Caution: Only use genuine replacement lamps, or potential damage may not be covered by
warranty.
WARNING
• The lamp heats up after continuous use and can burn your skin if touched, allow the lamp to
cool for at least 5 minutes before removing.
• Do not operate the UV lamp outside of the reactor as it emits powerful ultraviolet light that
can cause permanent damage to the skin and eyes. Never look at the lamp when the unit is
turned on.
• Handle the UV lamp by the ends only, do not touch the bulb of the lamp with your ingers.
• If the lamp’s surface becomes dirty, use a clean lint-free cloth and isopropyl alcohol to
remove the dirt or oil. Dirt or oil deposits on the surface may lead to premature failure of
the bulb.
Your UV system includes a visible/audible lamp failure indicator. In the event of a failure of the
UV lamp, the red LED light will lash, and a loud beeping will be audible from the electronic
ballast of the unit. The lamp life countdown timer will stop counting.
Please note that if these conditions occur and you are on an untreated water source, you
should immediately stop using the water for potable applications until the lamp is replaced and
disinfection of the distribution lines is completed.
The ultraviolet lamp has an approximate life of one year (9000 Hours). The built-in 365-day
countdown timer displays the number of days remaining until lamp replacement is required.
When the countdown timer reaches 0-days, an intermittent audible alarm will be activated, and
the display will indicate alarm A3.
To allow time to obtain a replacement UV lamp, the audible alarm can be silenced for seven days
by pressing and holding the button on the ballast for 25 seconds. After seven days, the alarm
will sound again if the lamp has not been replaced. This can be done a maximum of four times
which allows a total of 28 days to obtain a replacement UV lamp. After four times, the alarm can
no longer be silenced until a replacement lamp is installed. Then the lamp life alarm is reset to
365 days by pressing and holding the button for 10 seconds.
UV Lamp Replacement Procedure
• Remove the door and lid from your HPX system.
• Turn the water supply o using the shut-o valve located inside the HPX unit.
Relieve the pressure by opening a downstream tap or pressing the red pressure-relief button
on the ilter housings.
• Unplug the ballast from the electrical outlet. Allow at least ive minutes for the UV lamp to
cool.

• Carefully lift the lamp out of the chamber quartz sleeve by gently rotating/lifting the
lamp free.
• Disconnect the plug from the lamp and discard the lamp in an approved manner.
• Remove the new lamp from the packaging using a lint-free cloth and reconnect the
plug. Lower the new lamp into the sleeve and reconnect the VuCap.
• Open a downstream tap to allow air to be released and slowly open the water supply
allowing all air to be purged. Let the pump run for 23 minutes to purge air and lush
the system.
• Close the downstream tap and check for leaks.
• Plug the ballast into the electrical outlet.
• Ensure that the UV lamp is operating by checking that the green power LED light is
illuminated. The red lamp failure LED light should be o, and no audible alarm should
be active.
• The ballast display will show the number of days until lamp replacement is required.
If a new lamp was installed, press and hold the button on the ballast for 10 seconds to
reset the countdown timer.
• Reit the lid and door.

UV Sleeve Maintenance/ Replacement Procedure
Mineral deposits and sediment build-up on the quartz sleeve will aect the system performance
by decreasing the UV light transmitted through the quartz sleeve into the water column.
The proper maintenance and replacement of the pre-iltration required for the UV system will
reduce the accumulation of mineral and sediment residue on the quartz sleeve.
The quartz sleeve can be cleaned with a commercially available, non-abrasive, scale remover
(acidic) and a lint-free cloth. Cleaning of the quartz sleeve should be done regularly to ensure
maximum system performance. The amount of cleaning required will vary depending upon local
water conditions.
All traces of the cleaning solution must be fully removed from the sleeve before it is reinstalled
in the system. Take care to prevent any cleaning luid from coming into contact with the inside
surface of the quartz sleeve.
Caution: Only use genuine replacement UV sleeves or potential damage may not be covered by
warranty.
• Remove the door and lid from your HPX system.
• Turn the water supply o using the shut-o valve located inside the HPX unit.
Relieve the pressure by opening a downstream tap or pressing the red pressure-relief button
on the ilter housings.
• Unplug the ballast from the electrical outlet. Allow at least ive minutes for the UV lamp to
cool.
• Unwind the VuCap and release it from the chamber.
UV Sleeve Maintenance/ Replacement Procedure
• Remove the sleeve retainer nut and the sealing o-ring.
• Using a lint-free cloth, carefully lift the sleeve out of the chamber.
• Remove the spring and put it in a safe place for reitting.
• Carefully clean the sleeve using an alcohol-based cleaner – see details above. (UV sleeves
should be replaced every three years to maintain optimum performance)
• Reit the sealing o-ring to the sleeve’s open end, insert it into the chamber, and secure it with
the retainer nut.
• Insert the lamp and it the VuCap.
• Open a downstream tap to allow air to be released and slowly open the water supply allowing
all air to be purged. Let the pump run for 23 minutes to purge air and lush the system.
• Close the downstream tap and check for leaks.
• Plug the ballast into the electrical outlet.
• Ensure that the UV lamp is operating by checking that the green power LED light is
illuminated. The red lamp failure LED light should be o, and no audible alarm should be

Pump & Controller Maintenance
The pump and controller do not require any special maintenance and should operate for many
years before requiring service.
A periodic visual check is suicient to detect any problems before they cause failure. Look for
leaks or unusual noises as this may indicate seal or motor bearing failure.
It is recommended that any pump or controller servicing is done by a service agent.
Always ensure power and water is disconnected before doing any servicing.

Pump User Instructions
Surface Pump installation and Operating Instructions
Installation
Your Davies pump should be mounted on a irm level foundation in an area that is not susceptible
to looding or is exposed to the weather or wet areas.
Make sure your pump is situated in an area that is well ventilated; the maximum ambient
temperature must not exceed 40oc. (FIG C)
Connections
Piping
The piping must be ixed or anchored so as not to transmit any thrust, tension or vibration to the
pump.
The inlet pipe must be as short as possible, not smaller than the inlet of your pump and must be
correctly sized for the distance covered. All connections on the suction side must be perfectly
sealed and be able to withstand the suction created by the pump. Ensure that it does not rise
higher than the pump to prevent air locks.
If your pump is sucking from below itself a foot valve or check valve must be installed. If the pump
is being used with a pressure tank, a check valve must also be installed. Other applications may
also require a check valve. (FIG D)
A gate valve and pressure gauge should be itted to the discharge of the pump to maintain
optimum operating pressure.
The pressure in the pump must not fall below the minimum rated head of the pump during normal
operation.
Electrical
Before connecting your pump to the mains power supply, check that it is suicient to cope with
the motor consumption – see details on the pump. All single phase pumps under 10A are supplied
with cord and plug for New Zealand electrical outlets. Make sure the power supply is the same as
the details on the speciications label.
Single phase pumps have an internal overload but must also be installed with a Residual Current
Device (RCD).
Three phase pumps must be installed with overload protection supplied by the user and be set
around 510% higher than the full load amps shown on the speciication plate.
Electrical connections must be carried out by a qualiied electrician.
Starting
Before starting your pump, check the motor shaft turns freely, the electrical connections are tight
and secure, pipe connections are tight and thread seal tape or thread sealant has been applied.
Priming
Fill the pump body and the inlet pipe through the priming port with the liquid that is going to
be pumped (be sure the liquid is compatible with the pump, e.g. viscosity, suspended solids,
corrosive) (FIG A)
Put the priming plug back in and tighten.
Switch on the pump, if it is 3 phase observe the rotation -is it according to the rotation arrow
(FIG B), if not it will need to be changed. Now check the pressure gauge, if it reads zero after
1020 seconds the pump will need to be primed again.
Operation Instructions
Operation
Now that your pump has pressure, check that it is running within its operating parameters, if
the pressure is below the minimum head the gate valve on the discharge will need to be closed
slightly to allow the pump to run at a higher pressure. If the pressure is below the minimum
head stated on the name plate it will damage the pump.
Pressure systems
If the pump is being used as a pressure system (pressure switch and pressure tanks system)
the air pressure in the pressure tanks needs to be set correctly to allow the system to work
properly and protect your pump.
To set the air pressure in the tank, irst allow the pump to build up pressure to the turn o
point, with the pump now o open a tap to allow the pressure to drop slowly, observe the
pressure gauge on the system and note the pressure when the pump turns on. The air pressure
in the tank will need to be set at 25 psi below this point.
To check the air pressure in the pressure tank, switch o the pump, turn on the tap and allow
the pressure to drop to zero.
With a tyre air pressure gauge check the pressure in the tank and set it accordingly i.e. let
some air out of the tank or put some in with a tyre pump or air compressor to achieve the
desired pressure.
Check the pressure in the tank every 6 months.
If your pump is being used with an Auto controller there are no adjustments that need to
be carried out, the controller will automatically switch the pump on and o according to the
demand and protect the pump in the event of dry-run.
Maintenance
Surface pumps do not require any special maintenance apart from periodic visual checks for
any leaks or unusual noises.
Any leaking or unusual noises must be reported immediately as long term damage can occur.
If there is risk of freezing, the pump and pipe work must be completely emptied. (FIG E)
Always turn o the power to the pump before any maintenance or repair work is carried out.
