Continued
A drain pan is fitted to all units and a peristaltic pump is fitted as standard for units size 0 to 4
and will require customer connection to an appropriate waste system from the pump outlet.
It is important that the unit be mounted level. Failure to do so may mean the pump sensor is
not level and so compromise its operation. The pump has been design for use with water only.
As standard the position for the primary pump output is next to the controls section. Should
this position be inappropriate an alternate position is available on the opposite side of the
unit (see below). The necessary pipework to use this secondary position is already in place but
it will need to be connected to the outlet on the pump.
Doors and panels removed for clarity
Before the unit is fully operational it is recommended to perform an initial test to confirm the
pump and sensor are operating correctly. Ensure that all debris is removed from the
condensate drainpan. Manually add enough water to the drain to ensure the pump sensor float
switch is activated. Turn the unit on and check that pump starts and then stops as the water
level decreases.
The EVC Size 5 drain pan is fitted with an internal spigot suitable for connection with a Ø15 mm
push-fit straight connector, to be supplied by others. Terminate through the case onsite as
required, ensuring that any swarf is removed. Connect to an appropriate waste system ensuring
the connection is trapped correctly.
