Installation Instructions
Water supply Requirements
•Cold water inlet only, working water temperature 1-40 °C. Protect from freezing at all times.
•Supply pressure ≤500kPa. An approved pressure limiting valve must be installed by a licensed
person in situations where supply pressure could exceed 500kPa.
•Contamination could be present in the water system before the product is installed. Flush the
water system after installation and consult an expert if water treatment is required at the
source.
Environment Requirements
•The Hydroguard can be installed indoors or outdoors, but should be protected from harsh
chemical or salt air environments to prevent premature corrosion.
•The mounting xture must be solid and capable of supporting the weight of the product when
lled with water.
•Minimise exposure of the lter housings to direct sunlight and protect the system from
freezing at all times. Ambient temperature 1-40 °C.
Product and Position Preparation
Remove all packaging and dispose of it responsibly. Check all components are present and
undamaged.
Select a suitable location to install:
•The wall tting needs to be suiciently strong to support the weight of the product when lled
with water.
•Avoid locations where the unit is in direct sunlight or at risk of freezing.
•Check the location has suitable access to the supply and building plumbing, and be within x m
of a suitable power outlet. A licensed plumber or electrician may be required if appropriate
xtures are not available.
•At least 80 mm of clearance below the lter housings is required for the replacement of lter
cartridges. Refer to diagram below.

Mounting Installation
Installation steps:
1. Mark the desired location for the mounting xings. See Product and Position Preparation
2. Drill the holes and install the anchors (not included).
3. Align the mounting plate with the anchors and lower into place.
4. Tighten the xings to hold the system securely in place.
Plumbing Installation
If installing on a mains water supply, an approved backow prevention valve must be
installed by a licensed plumber according to local regulations.
1. Ensure the water supply is o. Connect the inlet and outlet plumbing to the product 1”
(25mm) connections. Unions (not supplied) are recommended at the inlet and outlet for easy
disconnection and maintenance. An isolation valve should be installed upstream and
downstream of the product to allow easy maintenance of the product.
2. Check that lter cartridges are installed in both housings. The 5 micron sediment lter should
be in the rst housing, and the CTO lter should be in the second housing (next to the UV
sterilizer).
3. Check that 2 sealing O-rings are clean, undamaged and assembled correctly to the lter
housing. If the O-rings are not lubricated, use 100% silicone food grade lubricant to assist
with assembly.
4. Screw the lter housings into the housing caps. Do not overtighten the housings.
5. Slowly turn on the water supply and check for leaks at all connections in and around the
product.
6. If there are no leaks, increase the supply pressure up to the maximum of 500kPa. Check for
leaks again and then open an outlet downstream to ush water through the line for 3-5
minutes. Check again for leaks and then close the downstream outlet.

Maintenance Instructions
Before any maintenance turn o the water supply to the product and open a downstream xture for a
few minutes or until the water ow stops. Close the downstream xture, and then press the red
buttons on top of the lter housing caps to release the pressure in the system. You may now begin
maintenance. Place a tray underneath, if required, to catch any water that splashes.
To resume ow after maintenance, slowly turn on the water supply to the product and check for
leaks. Open a xture downstream of the product for 3 minutes to ush water through the system and
remove any air pockets. Close the xture downstream and then check for leaks again. You may now
resume water usage.
Filter Cartridge Replacement
Replacement of the lter cartridges is recommended at least every 1 year, or as required due to the
supply water quality.
Steps to replace the lter cartridge (recommended at least every 1 year or as required):
1. Read the general maintenance instructions before
starting the lter cartridge replacement.
2. After isolating and release the system pressure. Loosen
the lter housing from the cap using the spanner to assist
(turn clockwise when looking from above).
3. Carefully unscrew the lter housing, taking care as the
weight of the lter housing with water can be heavy.
4. Empty excess water from the housing and remove the
lter cartridge. Please dispose of the lter cartridge
responsibly.
5. If necessary, clean the housing with dish soap and warm
water and then rinse thoroughly.
6. Remove all packaging from the replacement lter
cartridge. Record the model number of the cartridges you
use & install date in the maintenance log at the back of
this manual.
7. Insert the lter cartridge into the lter housing. For CTO
lters, ensure that the rubber seal on the top and bottom
are rmly in place before inserting into the housing.
Ensure the lter cartridge is correctly seated on the spigot
at the base of the lter housing.
8. Check O-rings are clean, undamaged and assembled
correctly to the lter housing. Replace if necessary and
lubricate using only 100% silicone food grade lubricant.
9. Hold the lter housing vertically whilst screwing the lter
housing back into the cap. Ensure the top spigot is
aligned with the center of the lter housing. Hand tighten
the housing until rm, being careful not to overtighten. Do
not overtighten the housings.
10. Read the general maintenance instructions on how to
restart ow after replacing the cartridges.
