DRAIN PIPEWORK

CONDENSATE PUMP
FLEXIBLE HOSE
CONDENSATE PUMP FLEXIBLE HOSE
• The unit is fitted with a condensate pump to ensure condensate removal.
• To insure that there is condensate flow, the drain tube must be installed with a fall of 2 % without obstructions,
or without rising sections.
• To avoid any unpleasant odours from the drainage system a trap must be fitted with a trap depth of no less than
50 mm.
• The condensate pump has a maximum lift of 200 mm. The rising tube must always be vertical.
• On completion the drain line must be insulated.
DRAIN TUBE
• The drain tube is connected to drip tray.
• This drain tube is supplied with a cap; the cap can be removed when it is necessary to remove any water that
accumulates in the drip tray.
INSTALLATION METHOD
1. The unit should be positioned centrally within the room. The
ceiling must be horizontal to ensure that the condensate water
can drain away thoroughly. The unit must be installed in a
position where there is sufficient strength in the structure to
support the weight of the unit.
2. Ensure there is sufficient space around the unit to service it.
Where there is a false ceiling ensure that there is enough space
to provide access. Where there is a false, panelled ceiling ensure
that there is sufficient space adjacent to remove the panels.
