1/ START UP
a/ Mains connection (Fig.10)
Connect the cable to the mains network in accordance with local wiring rules.
Identify a protective earth (ground) terminal.
b/ Safety switch connection (Fig.10)
IMPORTANT (EU): The high level safety switch comes with a dry contact rated NC at 250 V at 2 A inductive and 5 A resistive.
IMPORTANT (USA): High level safety switch comes with dry contact NC to be connected only to class 2 circuit not to exceed 42V
peak.
For a NC configuration (Fig.10), we recommend to use this contact to cutout the application, preventing condensate overflow.
c/ Hydraulic connection (Fig.7-8-9)
The pump unit should be installed horizontally, where the condensate drain pipe can enter into one of the 4 Ø30 mm (1 3/16'')
inlet holes at the top end of the pump or into one side or the other (see fig 7). The discharge connection is made through the
check valve, to which a tube of Ø int.10 mm (Ø 3/8'') should be fixed. For Ø int. 6 mm (Ø1/4'') pipe, a Ø 6 x Ø 10 mm (1/4'' x
3/8'') adaptor can be used. In this case, the flow will be reduced. The acceptable curvature of the tube's radius is 60 mm max. (2
3/8''). To fit or dismantle the valve tube, it is preferable to withdraw the check valve beforehand. Drilling for ACC00940 (Fig.7):
drill only on the mark provided for that purpose on one side or the other of the tank in order to avoid any detection system failure.
Please do not test continuously the pump. In case of too close operating cycles, the motor thermal protection can activate and
disable the pump during about 15 minutes.
d/ Installation / Settings (Fig.6-9)
The pump can be installed either on the ground, on a wall (fixing screws provided) or hanging from the ceiling, using the fixed slot
holes on the casing (to hang the pump from the ceiling it is necessary to use two threaded ro + nuts). It is possible to choose the
side of the water exit. To ensure proper ventilation of the motor, the pump must be free of any obstruction. Be careful not to bend
the flexible discharge tubing. A reinforced tube can be used. For the reduction in flow due to pressure loss, consult the flow chart.
When the pump is installed with a boiler (
discharge recommended, to avoid freezing pipes.
2/ USE
a/ Operation
Pour water into the pump. Check that the pump starts and stops once the water level begins to fall. To check the safety switch
operation, continue to pour water into the pump until the safety switch is set OFF (use a testing meter).
b/ Cleaning
The pump must be disconnected from the mains power supply before any maintenance work is carried out. The inside of the
pump should be cleaned regularly. Remove the tank and clean it with a mild cleaning solution such as water with 5% bleach (see
fig 11, the upper part can remain attached to the wall during this operation). At the same time, check that the float is clean and
free to move. Re-install the tank and re-check the operation (
to clean the tank every 6 months.
