The Advance Humidity Pump is supplied with a length of silicone tube to be fitted around the pump rotor.
This length will wear and need periodic replacement. It can also become flattened if left unused for some
time because the inside walls of the tube will stick to each other around the rotor and prevent water
passing through. Either replace this length of tube with a new 140mm (5 ½”) length or remove it and roll
it between finger and thumb to ‘un-stick’ it.
4.5
Cut a 190mm (7 ½”) length of silicone tube and fit to the pump inlet hose nipple (at the right end of the
pump). Pass this tube through the hole in the yellow moulding down into the water tank. Allow a loop as
shown to prevent kinks.
4.6
Cut a suitable length of tube to go between the incubator and the humidity pump e.g. 300mm (12"). Fit
one end to the outlet hose nipple on the pump.
4.7
Fill the pump water tank with clean water to no higher than the bottom of the yellow moulding.
4.8
Fit the rigid plastic tube onto the end of the silicone tube. The time taken for the system to prime can be
greatly reduced by sucking some water through most of the length of the tubes. This is easier if one hose
nipple is released from its slot so that the tube is loose around the pump rotor.
4.9
Pass the rigid plastic tube through the hole in the side of the incubator base. Pull it through and then push
it through the hole in the side of the water pot.
4.10
Cut a piece of the evaporating card to about 45mm wide (1 3/4") by 120mm long (5") and fold it in half
lengthwise. Fit it over the central rib in the water pot and position the end of the rigid plastic tube so that
it firmly touches the evaporating card. This will ensure all pumped water is soaked up by the card.
