Installation and operating instructions Wilo-DrainLift SANI-M 23
‡
Pressure pipe completely filled with water.
1. Activate the lifting unit: Insert plug into socket.
2. Select automatic mode on the switchgear.
3. Open the gate valve in the inlet and pressure pipe.
▶ The lifting unit operates in automatic mode and is controlled depending on level.
8.1 Application limits
Improper use and overstraining leads to damage to the lifting unit. The following appli-
cation limits must be strictly observed:
ƒ
Max. intake/h: 3000 l (792.5 US.liq.gal)
ƒ
Max. positive suction head: 5 m (16 ft)
ƒ
Max. pressure in the pressure pipe: 6 bar (87 psi)
ƒ
Fluid temperature: 3 ... 40 °C (37 ... 104 °F), max. 65 °C (149 °F) for 5 min
ƒ
Ambient temperature: 3 ... 40 °C (37 ... 104 °F)
8.2 During operation
CAUTION
Material damage due to pressure surges
Pressure surges can occur when switching off the pump. These pressure surges can
damage the pressure pipe and the lifting unit. Increase the follow-up time to pre-
vent the pressure surges. An extended follow-up time results in slurping operation
and the swing check valve closes more smoothly.
NOTICE
System problems when delivery head is too low
If the geodesic delivery head is below 2 m (6.5 ft), a leakage can occur in the collec-
tion reservoir. The swing check valve does not close tightly due to a lack of required
counter pressure. This can result in repeated activation (cycling) of the lifting unit.
ƒ
Open gate valves in the inlet and pressure pipe!
ƒ
The maximum inflow must be lower than the maximum output of the system.
ƒ
Do not open inspection openings on the collection reservoir and swing check valve!
ƒ
Ensure aeration and venting of the collection reservoir!
8.3 Emergency operation
8.3.1 Failure of the level control
If the level control fails, drain the collection reservoir in manual mode. For all relevant
information on manual mode, refer to the installation and operating instructions for the
switchgear.
CAUTION! Continuous duty is not permitted! Observe the operating mode. The op-
erating mode indicates the activation period and the downtime!
8.3.2 Failure of the lifting unit
If the lifting unit completely fails, pump out the sewage using a diaphragm hand pump.
1. Close the gate valve in the inlet.
2. Close the gate valve in the pressure pipe.
3. Pump sewage into the pressure pipe using the diaphragm hand pump.
