⚠
The water in the PROBOIL tank may be up to 98°C and as such represents a scalding risk if handled without due care. We
recommend that the boiler is switched off on the front panel before draining any stored water. It will take approximately 8 hours
(overnight) for a full 98°C tank to naturally cool to a touch safe temperature of 46°C. Do not open the drain valve until the hot water
is at atmospheric pressure. Should you need to drain the boiler without allowing it too naturally cool, then you must take adequate
care and use personal protective wear to prevent accidental scalding from hot water, surfaces and steam drained from the front
drain valve.
1) Use the Hotkey to drain hot water from the tank until no more water can be dispensed.
2) Ensure the boiler (A1) is turned off at the front control panel and allowed to cool down.
3) Remove the slotted screw (A10) from the access plate (A11) at the bottom of
the boiler front panel, place it somewhere safe so it does not get lost
accidentally.
4) Remove the slotted screw (A10) from the access plate (A11) at the bottom of
the boiler front panel, place it somewhere safe so it does not get lost
accidentally.
5)
Place a washing up bowl or bucket on the floor below the level of the drain.
Note: a 5 litre vessel capable of holding hot fluid safely is required.
6) Connect the adaptor (A13) and drain hose (A14) to the valve and hand tighten. This part was supplied with the product
originally, if it has been lost then a ½" female hose can be connected to the drain valve (A14) instead.
7) Turn lever (A12) to open valve and allow water to drain into washing up bowl or bucket.
8) Once all the water has drained from the unit close the drain valve (A12).
9) Gently shake the drain hose (A14) then disconnect the drain hose.
10) Place coiled drain hose (A14) into the compartment and replace cover (A11)
using the hand screw (A10).
⚠
take care not to move the drain valve (A12) from the closed position
when replacing the drain hose (A14).

11)
Safely and carefully dispose of the drained waste water.
12) Turn the power off by unplugging the power lead (A2) at the mains.
13) Ensure to fully turn off the ½" (15mm) x ½" (15mm) x ¾" 3 way isolating tee (E4). Note: Off position shown in
'Parts and contents' drawing.
14) Disconnect connection lead (X4) from data connection lead (A6).
15) Disconnect ¼" blue tube (C10) from ¾ BSPF x ¼"" push fit (C13).
