WATER REQUIREMENTS
WATER SUPPLY INSTALLATION
The cooler requires a permanent water supply to be connected.
An Inlet Solenoid Valve, controlled by the water management
system, allows water into the cooler when required.
INSTALLATION OF THE WATER SUPPLY MUST CONFORM
TO LOCAL PLUMBING RULES, REGULATIONS AND
STANDARDS.
The following specifications for water supply are required:
Water Connections:
½" BSP (Aus/Eur), ½" NPT (USA)
male connection supplied suitable for a compression fitting.
Water Supply:
100kPa (15psi) - 800 kPa (115psi)
10L/min (2.6 gal/min) MINIMUM
20L/min (5.3 gal/min) RECOMMENDED
Water Supply Temperature:
40°C (105°F) MAXIMUM
Water Supply Salinity:
100 to 1150μS/cm
WATER SUPPLY PRESSURE REGULATION
The Installer must provide a pressure regulator in the water
supply line adjacent to the cooler to regulate water supply
pressures between 100kPa (15 PSI) and 800kPa (115 PSI).
Important! Water pressures which are lower than 100kPa (15
PSI) will prevent the inlet solenoid valve from opening.
Important! Water pressures which are higher than 1200 kPa
(175 PSI) and/or water temperatures which are higher than
40ºC (105ºF) risk inlet solenoid valve failure.
If a non-return valve is installed in the water supply line, it
is recommended that a suitable pressure relief valve is also
installed between the cooler and non-return valve to limit the
pressure rise associated with the heating effects of ambient
temperature and solar radiation.
WATER SUPPLY ISOLATION
The Installer must provide a manual 1/4 turn ball type shut off
valve (do not use a stop cock) in the water supply line adjacent
to the cooler, subject to local plumbing regulations. This allows
the water supply to be isolated whenever work needs to be
done on the cooler.
In areas where temperatures can cause water supply pipes
to freeze, a drain down facility should be provided during the
installation. This drain down facility must be activated prior to
freezing conditions, to avoid possible damage to the cooler
components.
WATER SUPPLY FILTRATION
The Installer must provide an inlet water filter in the water
supply line, external to the cooler, to prevent any debris from
entering and damaging cooler components.
Important! Flush the water pipe to remove any contaminants
(swarf, filings or dirt) before final fitting. Contaminants can
lodge in the inlet solenoid valve, preventing it from functioning
correctly.
The cooler's water management system is designed to use
water that is suitable to be classified as 'potable' and fit for
human consumption. If alternative water (including rain water) is
to be used that contains unusually high or low levels of salinity,
hardness, acidity or chemical contaminants, then additional
filtration or treatment systems should be employed to render the
water 'potable'.
WATER HAMMER
Not all installation pipeworks are the same, and some may
require additional prevention against water hammer.
If water hammer is a problem, it is the responsibility of the
Installer to fit an appropriate water hammer arresting device
external to the cooler.
WATER INLET SOLENOID VALVE
The installation kit contains the inlet water solenoid valve kit and
a hose set which must be fitted on-site.
It is a requirement to fit the new detachable hose set supplied.
Any old hose sets should not be re-used.
Follow the instructions provided in the kit to fit the valve and
covers.
Plug the solenoid power cable into the main control board
