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
½
”
BSP
Min Water Pressure
15psi (100kPa)
Max Water Pressure
115psi (800kPa)
Min Water Flow
2.1 gallons/min (8 liters/min)
Max Water Temperature
104°F (40°C)
Important!
If the water pressure exceeds maximum
specification then a pressure reducing valve is required and
must be supplied and fitted by the installer.
WATER CONNECTIONS
A permanent water supply is required to be connected to the
cooler. The water connection point is located on the underside of
the cooler pan (reservoir). You must install 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.
COOLERS WITH DRAIN VALVES
For coolers with the inlet solenoid valve fitted, the water
connection is a 1/2” BSP compression fitting on the end of a
flexible hose. The flexible hose is connected to the float valve.
The 1/2” BSP Compression fitting can be directly screwed onto
the water pipe or be directly screwed 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 solenoid and float valve,
preventing them from functioning correctly.

INSTALLING THE INLET SOLENOID
For coolers fitted with a drain and solenoid valve, it is a
requirement to fit the new detachable hose set as supplied.
Any old hose sets should not be re-used.
For EXVQ model coolers, fit the inlet solenoid under the pan
(reservoir) as shown:
Ensure washers are correctly located. Do not over tighten
plastic fittings.
Insert the solenoid cable through the hole in the cooler pan
(reservoir) (behind the drain valve) and connect to the water
solenoid valve. Make sure the cable is fitted to the groove
underneath the pan so it does not get trapped by the solenoid
cover when fitted. The cable leads can be connected to the
solenoid either way around.
Important!
The cable must wrap underneath the solenoid.
ILL1676-A
Use thread seal tape between solenoid hose assembly and
brass ½” BSP to ¼” compression adaptor or ½” BSP Nut.
Note!
Tighten the solenoid valve until it seals against the rubber
washer and is in the orientation shown such that the solenoid
cover will clip on over the top.
The water solenoid is required to be installed in the direction
of flow as per the arrow indicator on the solenoid.

INSTALLATION
Run the cable to the roof space and then to the controller via
the mains power cable entry point and plug in to the rear of the
wall control.
Note!
The maximum length for the wall control cable to travel
alongside the power cable is 33’ (10m).
WARNING!
Do not let the cable, the cable ends, or the control
box get wet. Position the cable in the dropper so they will be
accessible from inside the roof space.
