3. Commission and Check Water Connections
• Before plugging the tank into the power socket, the system must be full of water
and tested for leaks. Open all water valves to allow water to flow to the boiling
water tank.
• Pull the tap handle out to release the safety lock (see Section 5) and turn towards
the red marker to fill the tank, this will take approx 1 minute. When the tank is full,
water will flow from the spout.
• Check water flows smoothly from the tap to ensure all air has been purged from
the system (this could take up to 1 minute).
• Repeat the process for the cold water side turning the handle towards the blue
marker. Safety lock release is not required to dispense cold water.
• Test the pressure relief valve by twisting the red cap until water flows from the
valve.
• If it is discharging whilst the heater is turned off this is a sign that the incoming
pressure exceeds the 4.2 bar rating of the pressure relief valve. A pressure reducing
valve is required (not supplied).
• When the air is purged, the tap is closed and the system is fully pressurised, inspect
all connections for leaks.
• Flush each filter through ensuring the water runs clear.
• Ensure there are no obstructions in the expansion zone between the manifold and
the tank.
4. Electrical Connection
• Ensure that the installation area is dry.
• The boiling water tank is supplied with a pre-wired (1m) BS plug.
• Insert the plug into a suitable socket and turn the power socket on at the switch.
• The boiling tank will take up to 13 minutes to heat up from cold, depending on
incoming water temperature.
