Installation
1. Carefully unpack the unit, check for damage and make sure
that all of the required parts are included. The units are tho-
roughly tested before packing to insure safe delivery and
operation. If there is any sign of damage due to shipment,
return it to the place of purchase for repair or replacement.
2. Choose a mounting location near the air-conditioner or boi-
ler. The pump must be mounted level. And the inlet must be
below the lowest drain.
3. The pump should be mounted in a way that the cover (EE-
400NEO) and/or the pump unit inside (EE150 and EE300)
can be removed easily for cleaning purposes.
Connecting the piping
1. Run flexible tubing or pipe from the condensate drain on the
evaporator pan and/or drain from boiler to the inlet hole on
the pump. This drain line should have a continuous down-
ward slope to allow gravity flow. Cut the end of the line at
an angle so the end does not close off on the bottom of the
pump's tank.
2. Connect the discharge line by hand- tighten the cap nut of
the check valve in a clockwise direction. Flexible tubing
with a size of 8x2 mm will be suitable. Extend the dischar-
ge line straight up from the pump to the highest point, run
the discharge line to a drain with a downward slope.
Note: Condensates discharged from condensing boilers can
contain residual contaminants like soot & unburned hydrocar-
bons. In these systems, it is essential that the contaminated
condensates are treated before being delivered to the pump.
Failure to comply with these requirements can cause equip-
ment malfunction.
Wiring
Shut off electrical power at the fuse box before making any
wiring connections. All wiring must be done according to local
and/or applicable national codes.
1. Main power connection: All pumps are equipped with a 1.5
m power cord. Connect this cord to a constant line voltage
source, not a fan or other device that may run intermittently
2. Overflow alarm switch: The pump models EE400NEO and
EE300 are equipped with an overflow alarm switch (NO/NC)
which should be connected. The alarm contact of the EE-
400NEO will be activated with a 5s time delay.
Testing
1. Functional test: Connect the main power cord of the pump.
Manually fill the tank with water until the pump turns on.
Note: The pump is taught-in during initial operation. If the
teach-in process fails, it can be reset by pulling out the
mains plug (only EE400NEO).
2. To test the overflow alarm circuit (EE400NEO & EE300 only)
A. Kink the tube coming from the pump discharge so it can-
not pump out.
B. Pour water into the pump reservoir, filling it completely.
C. As the water level nears the top of the unit, the alarm
contact (EE400NEO, please see "Wiring", pos.2) should
activate and trigger the desired function (e.g. acoustic
signal)
D. Un-kink the tube and allow the pump to empty the tank.
As the water level goes down the overflow alarm contact
will be deactivaed and the appliance will energise again
(or the alarm will reset).
Maintenance
Warning! Before attempting any maintenance on the unit, dis-
connect the power cord from the power supply to avoid the risk
of electrical shock.
Attention: The overflow alarm circuit (EE400NEO and EE300
only) can still be under power.
If the pump does not perform as stated in above tests, remove
the tank cover of the pump (EE400NEO only). The drive unit can
be removed and cleaned now. The EE150 and EE300 can be
opened by inserting a screwdriver in one of the side slots of the
tank and levering it away (do not over-stress the material). Af-
ter that, unscrew the two Phillips screws located on top (EE150
only). Now verify that the float mechanism moves up and down
freely. If the float binds, it may be dirty or damaged. The motor
itself does not need any maintenance so do not attempt any
repairs. Also, never open the drive unit of the EE400NEO becau-
se breaking the seal will invalidate the warranty. However, the
tank and float mechanism will need to be cleaned once a year.
The tank, pump and the floats should be cleaned with mild de-
tergent using a damp cloth. Reassemble the pump in reverse
order.
Cleaning the check valve and verify its operating
1. After unscrewing the cap nut remove the discharge line
from the check valve
2. Use a SW 20 wrench to remove the check valve from the
drive unit.
3. Visually check the valve for obstructions. If damaged, repla-
ce.
4. To re-install the check valve, hands tighten it to the drive
unit. Then, tighten 1/2-turn further with a wrench.
Attention: Be careful not to over-tighten as this may distort the
O-ring seal under the check valve.
Replacement items
The discharge nipple with integrated check valve is available
for replacement. (see table)
