f) Connect the detector to the pump
• Connect the telephone type RJ11 connector to the pump.
• Connect the 6 mm bore flexible tube to the ribbed outlet on
the pump as shown in Fig. 3.
• The arrow on the pump body shows the direction of water
flow.
g) Connect the pump
Connect the 6 mm bore flexible tube between the ribbed outlet
on the pump and the common condensate drain.
h) Mains connection
• Connect the power supply of the ICM to the mains supply
(as shown in Fig. 3) by means of:
- an interconnexion cable (HO VVF) with 0.75 mm
2
length,
provided with an electric protection and isolating device
(not supplied) conforming to IEC 345 standard on phase
and neutral
- a fuse on phase of 630 mA.
WARNING:
Before power supply, make sure that the cover of the pump
unit is properly closed.
i) Connect the alarm
The condensate level detector consists of a float which can
detect three different levels:
• Pump on level: 17 mm ± 2 mm of condensate. When this
level is exceeded the pump will start automatically.
• Pump off level: 11 mm ± 2 mm of condensate. When the
pump has been operating, it will shut off when the level falls
below this threshold.
• Alarm level: 21 mm ± 2 mm of condensate. This situation
generates an alarm from which recovery is by means of a
dry-reed output. If the alarm threshold is reached or
exceeded, the condensate drain pump keeps running.
The alarm condition applies if the condensate level is above
the alarm threshold.
The alarm condition no longer applies when the level is below
the alarm threshold.
The device includes a potential-free changeover switch with a
capacitance of 8 A/250 V (resistive load)
The alarm contact on the drain pump is a “Normally Open” or
“Normally Closed” type, and therefore:
If the condensate level is below the alarm threshold (no alarm
condition), the contact is open if the wiring is NO or closed if
the wiring is NC.
If the condensate level is above the alarm threshold (alarm
condition), the contact is closed if the wiring is NO or open if
the wiring is NC.
j) Function test
Tip a small quantity of water into the drain pan. Check that the
pump starts, draws water away and stops when the water level
falls. Add more water until the alarm operates.
k) Service
Timing: at the beginning of the season.
Clean the detection unit and the filter. Disconnect from mains
supply before opening.
Remove the lid, remove the filter, remove the float, clean the
detection unit and the float using a solution of water containing
5% bleach. Replace the float in its initial position (magnet
faced upwards), reinstall the filter, reinstall the lid and screw it
down. Carry out an operating test on the pump and the alarm. If
the air conditioner is installed in areas liable to cause of favour
extensive contamination of the condensate water, clean more
frequently.
l) Features of the condensate drain pump

m) Safety
• The alarm contact will prevent overflow (cutting-off the
cooling)
• An auto-reset thermal circuit breaker with a cut-off
temperature 70°C
• Earth connection of pump
• Safety transformer as per standard EN 60 742
• Housing made of ABS
