Introduction
The Puretec Freestanding Water Chiller System is designed to run economically for many
years, dependent on the initial installation and periodical maintenance.
Flush systems for 10 minutes aer any period of non-use more than 2 days.
The Freestanding Water Chiller System is designed to operate with mains water.
Installation Note: A water dispensing appliance, like any product, has a limited life
and may eventually fail. Also sometimes failure happens early due to unforeseen
circumstances. To avoid possible property damage, this product should be regularly
examined for leakage and/or deterioration and replaced when necessary. A drain pan,
plumbed to an appropriate drain or outfitted with a leak detector, should be used in
those applications where any leakage could cause property damage, and/or the water
supply should be turned off if no one is home/present.
ALL INSTALLATION AND SERVICE WORK SHOULD BE COMPLETED BY
QUALIFIED TRADESPEOPLE. FAULTY OPERATION DUE TO UNQUALIFIED
PERSONS WILL RESULT IN VOIDED WARRANTY COVERAGE.

Installation Requirements
Installation Requirements
The following is a guide but the installer is responsible to comply with any local
regulations that may be applicable to this type of installation.
1. Install near a convenient place to connect to a mains pressure water supply of
drinking water quality and 220 - 240V/50Hz electrical supply.
2. Avoid areas exposed to excessive heat, humidity, rain, saltwater or snow or direct
contact with water spray or splashing.
3. Avoid positions of direct sunlight or solar heat.
4. Install only on flat, level and well supported surfaces.
5. Avoid tilting the machine during installation. If the machine has been tilted
excessively for more than a few minutes during or before installation, leave to
stand for approximately one hour before switching on.
6. Allow an air gap of at 100 mm each side and at the front of the machine.

2. Assemble the carafe filler by inserting the gooseneck outlet into the carafe filler
base that comes installed on the sink. Ensure the gooseneck outlet is pushed in
hard until properly sealed.
3. Connect the 40 mm drain outlet using appropriate 40 mm DWV pipe, fittings and
sealing compound to suit the installation.
4. Connect the inlet water supply to the ¼” tube fitting at the rear of the cabinet and
ensure there is an easily accessible shutoff valve on the water supply line. Fit a
pressure reducing valve to regulate the water pressure if required - max 500 kPa.
5. Switch on the water and check all tubing and fittings for water leaks.
6. Test the dispenser connections by pressing the bubbler button to ensure flow, then
by turning the carafe handle to ensure flow.
7. When new it may take up to 3 minutes to fill the system prior to dispensing water.
8. Connect the power cord to a standard 240V powerpoint and switch on the electrical
supply.
9. Refit the front panel.
10. Allow 1 hour for the water to cool before the water reaches its operational
temperature.
11. To protect the compressor, allow the unit to stand for at least 1 hour aer moving
before switching it back on.

Operation & Maintenance
Operation & Maintenance
• Frequently clean the fountain using warm soapy water. Avoid all abrasive and
corrosive cleaning materials.
• Do not pour any waste cleaning water down the drain to avoid blocking the drain
trap.
• If the chiller is not used (e.g. more than 3 days) the power can be switched off to
conserve energy.
• We recommend that the fountain is cleaned aer any period of disuse.
• Keep the area surrounding the fountain clean and dry. In the event of any leakages,
switch off the water and power and call Puretec.
• For models where a filter kit is supplied, Puretec recommends changing the filter
every 6-12 months, when taste and odour return or when you detect a decrease in
flow, whichever comes first.
Use Guidelines
• Use for mains water supply.
• Minimum operating pressure 100 kPa.
• Maximum operating pressure 400* kPa.
• Do not allow exposure to temperatures below 0 °C, protect from freezing.
• Maximum operating temperature 38 °C.
• System must be installed according to local plumbing codes on the cold water line
only.
Caution: Do not use with water that is microbiologically unsafe or of unknown quality
without adequate disinfection before the chiller.
* Where line pressure exceeds 400 kPa, an approved pressure limiting device must be
installed (350 kPa limiting valve is recommended for D20C) and must also comply with
Australian & New Zealand Plumbing Standards. (Ref. AS/NZS 3500.1:2021, Clause 3.3.4).

External Filter Kit Installation
D20C-K models include a separate water filter kit. Follow the below installation steps;
1. Select suitable location that is close to the Freestanding Water Chiller System.
Remember to allow access room for changing filters and a suitable place where
water spillage will not cause damage. Location should not be in direct sunlight.
2. Isolate water supply. Uninstall the connections on the cold water line and connect
the tubing, a Smart Tee™ (sold separately) is recommended. Reinstall the previous
connection to the tee valve.
3. Connect a pressure limiting MultiValve (sold separately) to the tee valve with a
length of White Tubing.
6. Install filter cartridge by positioning it in the desired location, marking the position
of fixing hole and fixing with bracket screw. The filter can be mounted horizontally
or vertically. Allow room for the connecting tubes. Ensure flow arrow on the filter
cartridge is in direction of the water flow.
7. Fit tubing into connectors. Allow slack in the tubing.
8. Restore the water supply and check for leaks.
9. When new it may take up to 1 minute to fill the system prior to dispensing water.
Run the system for at least 5 minutes to remove carbon fines. Water may appear
milky, but this is normal and is only tiny air bubbles that will clear aer a short
period.
