IMPORTANT INFORMATION AND SAFETY INSTRUCTIONS
PLEASE READ ALL INSTRUCTIONS CAREFULLY
When installing and using all electrical appliances, basic safety precautions should always be followed including the following:
ELECTRIC SHOCK HAZARD
To prevent electric shock, do not place cord, plugs or appliance in water or other liquid.

Do not attempt to service this product. Repairs should be done by authorized service personnel.
Do not use outdoors or in damp areas.
FIRE HAZARD
When installing the appliance, allow a minimum airspace of 100mm around the back, sides, and top of the chiller unit for air circulation. Nothing should be placed in
front of the unit and there should be a 150mm air space in frontof the warm air outlet maintained at all times
PERSONAL INJURY
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge,
unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

A standard 10amp 3pin power outlet conveniently placed within 1m of the intended location of the boiler tank. This must be installed by a qualified electrician.
Water supply
A standard Cold water supply fitted with a 15mm stop tap situated within easy access of the intended location of the boiler tank. This must be installed by a qualified
plumber.
Supply water pressure must not exceed 1000kpa with pressure regulator installed.
Water supply must be microbiologically safe.
PROPERTY DAMAGE
In situations where any water leakage could result in damage to property, the complete Schwan Installation should be installed over a Drained Safe Tray,
plumbed to an appropriate drain.

Fault Cause Action
Chiller system will not start No power / water or faulty chiller unit
Check power and water supply is on,
if so then shut down unit
Call MERQUIP
Unit chilling full time and producing
cold water
Ventilation below min requirements.
The unit is running at MAX capacity.
Increase cabinet ventilation make
sure the chill temp is not on MAX. if
still faulting shut down unit and Call
MERQUIP
Unit Chilling full time but water is not
cold.
Unit has little or no ventilation
The unit is being over used.
Check specs on unit instillation if
these are all meet and unit is not
being over used then shut down unit
Call MERQUIP
Stop tap open but unit has slow or no
cold water
Filter needs changing, water supply
is blocked or there is not enough
water pressure
Replace filter, if still slow shut down
unit and Call MERQUIP
Sparkling water has little or no fizz
CO2 bottle empty, CO2 pressure
below 3 Bar or the water temp is too
high
Adjust CO2 pressure check water
outlet temp is below 10degC then
replace CO2 bottle if fault not fixed
shut down unit and Call MERQUIP
Only gas comes out of Sparkling
water outlet
Water supply is not sufficient or there
is none at all
Safety NO WATER system has
tripped
Check to see if red NO WATER light
is on make sure stop tap is open if
fault continues shut down unit Call
MERQUIP
Still water comes out sparkling Not enough water supply or
clogged valves
Shut down unit
Call MERQUIP

Twist old filter to the left to
remove.
Remove and discard the
yellow cap from the new
filter cartridge.
Insert new filter cartridge
into the filter head and twist
to the right until the “stop”
is reached
Run the cold water for 5
minutes to clear any air
bubbles and to condition
the filter for use.
ON
Leave water supply ON
Filter has auto shutoff valve
To ensure your Schwan drinking water system continues to provide you with
fresh filtered chilled and sparkling drinking water, your Schwan filter cartridge
needs to be replaced at least every 12 months.
In some situations where there is a lot of sedimentation or chemicals in the
water supply, it may be advisable for the filters to be replaced more frequently
to avoid annoying slow water flow or chemical taste issues.

CO2 adjustment
By adjusting the knob on the regulator you can adjust the carbonation of the water. The more pressure
applied the more sparkle you get. Watch gauge on regulator and make sure the pressure doesn't ex-
ceed 5 Bar. We recommend not having the unit under 3 Bar as the unit will not produce enough sparkle.
3-5 Bar
3-5 Bar
Pressure UP
Pressure DOWN
After adjusting pressure
run tap until pump starts
then re-adjust pressure
continue process until
right setting achieved.
Pressure must not exceed 5 bar

Water temp adjustment
Water temp colder
Water temp warmer
NOTE: turning chiller on MAX chill could cause it to ice up, use MAX setting at own risk. Water
temp effects the carbonation of the sparkling water — the warmer the water the less fizz the water
will hold. The overall best setting to have chiller on is setting 6.
NOTE: Use flat blade screw driver to adjust water temp

Typical installation layout
In situations where any water leakage could result in damage to property, the
complete Schwan installation should be installed over a Drained Safe Tray,
plumbed to an appropriate drainage connection.
WARNING
NOTE
Allow a minimum of 100mm air space around the sides,
back and the front of the chiller.
Cabinet must be vented to provide air flow, see venting
diagram on next page.
The filter system and CO2 bottle must be easily accessible
for routine maintenance and changing.
The filter must be less than 600mm from the chiller inlet.
Use no more than 800mm of 1/4” water supply tube from
stop tap to chiller inlet.
Tap base must be within 700mm of chiller outlet

Venting requirements
Cabinet must have an air inlet vent at the bottom and outlet vent
no more than 200mm from the top
There must be a 100mm air space on
both sides of the under bench chiller The front of the unit must have
at least 100mm of air space
The back of the unit needs
100mm of clearance for tubing.
The amount of air space around the unit apply for both passive and fan forced ventilation

12
Top vent must be a minimum size of
220mm x 90mm and no more than
200mm from top of door
Vent
Vent must have a minimum of
60mm of air space behind
door for air flow out of cabinet
Bottom cut out of the cabinet
must be at least 200mm x
40mm
The measurements given are the minimum sizes required to provide sufficient air flow to cool the compressor, any
less air flow and the units capacity will be effected.
If there is not enough room to place the right size vents or
the cabinet temp is reaching over 27oC
the cabinet will need to be vented using a fan forced system to provide enough air flow.
