INSTRUCTIONS FOR USE: Original Chill ™ hot tubs
In case you are using your own pump for filling the tub, remove the pumping hose after you have
filled the tub. Many pumps do not have a return valve to prevent the water discharge from the tub
when the pumps are switched off. Before filling the tub, check that the bottom plug of the tub is
closed, ensure that the plug is in place after you have some 10 cm of water in the tub.
Minimum fill:
The tub needs to be filled at least 5 cm above the upper
connection pipes of the stove before lighting the fire in the
stove (picture on right).
Do not let a full tub freeze in the winter. Empty the tub or
ensure appropriate heating.
Do not connect the stove to the circulation pump; it cannot
ensure the pressure because it is planned only for
gravitational circulation.
Note about the minimum fill and heating the stove!
The tub stove must never be lighted when the tub is empty or not full! Heating a half-
empty tub will lead to melting the stove! You must not start emptying the tub before the
fire and embers have burnt out completely. Heating a half-empty tub will lead to melting
the stove!
The water is layered when it heats up and, therefore, it needs to be mixed so that the actual
temperature can be found. The optional cover should be in place when heating the water.
Do not leave the water unattended, in case there is a risk of subzero temperatures. The bottom
plugs and exhaust valves need to be left open, so that any water collected in the tub can be
discharged and it will not freeze at subzero temperatures.
You can use 19 mm spanners for the outer edge of the hoop tighteners. These
tighteners are used for adjusting the hoops. You do not usually need to adjust
these in a plastic tub. If the side planks dry and shrink you can adjust the hoops
accordingly. Check that the planks are situated nicely before tightening so that they will not bend
out or in between the hoops and actual tub.
LIGHTING AND HEATING THE STOVE
The use of
Micu
stoves is as easy as using any other normal stove. The door has fixed sized air
holes. Air adjustment plate for the door is sold separately. There is an installation hole in the door
and guides in the back for it. The heater does not have grates the fire is made directly on top of the
heater floor.
Use smaller and dry kindling wood for igniting the fire and then add bigger pieces as needed every
10 to 15 minutes. Maintain the fire in the stove during heating, so that the wood will burn properly
and the tub will heat with maximum power. If the fire is too small, the heating time becomes
remarkably longer.
Use any lighter fluid according to the instructions. Do not use any other fuels for lighting. We
recommend lighting pieces, e.g. Burner paraffin bags.
