INSTALLATION
Ensure the venturi is sitting flat in the pan (reservoir) by
checking all the venturi ribs are in contact with (D). Relocate the
tabs on the venturi back into the slots in the pan (reservoir), as
it was fitted during transport. The venturi securing screws (x2)
do not need to be re-fitted.
WATER REQUIREMENTS
Installation of the cooler water supply must conform to
local plumbing rules, regulations and standards.
The following specifications for the cooler water
supply are required:
Water Connection
Min Water Pressure
Max Water Pressure
Min Water Flow
Max Water Temperature
Important! If the water pressure exceeds maximum
specification then a pressure reducing valve is required and
must be supplied and fitted by the installer.
A permanent water supply is required to be connected to the
cooler. The water connection point is located on the underside of
the cooler.
You must install a manual quarter 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.
The water connection is a 1/2" compression fitting or a 1/4"
compression fitting. This can fit directly onto the water pipe or be
screwed directly onto the manual water shut-off valve.
Always ensure that the water pipe connection does not place
sideways strain onto the float valve.
Important! In areas subject to freezing, the water supply line to
the cooler requires a drain down facility at the lowest point in the
water supply pipe.
Important! Flush the water pipe to remove any swarf before
final fitting. Swarf can lodge in the float valve, preventing it from
functioning correctly.
