Description and function

Description of the unit

• An automatically operating small lifting unit (Fig. 3) including all required switching and control mechanisms, with non-return valve, active carbon filter, elastic pressure port and connections for a toilet, two additional drainage fixtures and a ventilation pipe.
• The DrainLift XS-F small lifting unit is directly connected to the outflow bend of a wallhung toilet.
• The direct toilet connection and the connections for additional drainage fixtures are on the longitudinal sides of the unit, and the two ventilation ports are on the top of the tank. The fluid flows out through an elastic, rotatable pressure pipe.
• Ventilation takes place via the active carbon filter supplied into the installation room, or odour-free via a ventilation pipe through the rough.

Connections

1. Pressure pipe
2. Ventilation pipe
3. Inlet for wall hung toilet, HT pipe DN 100
4. Inlet pipe for shower/bidet
5. Inlet pipe for washbasin

Dimensions

Function

• The DrainLift XS-F has a level switch, which switches on the pump according to the water level. It is switched off automatically after a set time.
• The motor winding is protected by an overload safety device which automatically switches off the pump and switches it on again after it has cooled down.
• An integrated, mains-dependent alarm signal (buzzer) signals any operating faults which occur. An additional potential-free contact (5 A/250 V) on the board can be used to forward the signal.

Installation and electrical connection

DANGER! Risk of fatal injury!

Incorrect installation and inexpert electrical connection can pose a risk of fatal injury.

• The installation and electrical connection may only be carried out by qualified personnel in accordance with the applicable regulations!
• Observe the regulations on the prevention of accidents!

Preparing for installation

The DrainLift XS-F is designed for front wall installation (Fig. 4). The unit is installed directly beside the module for a wall-hung toilet.

• The unit must be installed in a room protected from frost.
• The installation surface must be horizontal and flat.
• The lifting unit and its electrical connection (power plug) must remain accessible for maintenance after it is installed.

**Front wall installation

**

Modules for front wall installation

• The DrainLift XS-F can be combined with all commercially available front wall installation systems. The main installation conditions for the unit are shown in Fig. 5. To guarantee accessibility, there must be a service hatch of at least 500 x 400 mm. An installation kit for making a service hatch is available as an accessory.
• If the front wall depth is 200 mm and several modules are aligned on a floor-mounted rail larger than 37 x 37 mm, a compensating plate may have to be placed under the unit.
• The plate should not be too thick, in order to ensure a sufficient fall in the drain pipe of the toilet bowl. The shower must also be placed higher by the thickness of the plate.

Modules for front wall installation

Inlet ports

The toilet connection (Fig. 4, Pos. 4) takes place directly with the outflow bend of the front wall installation and an HT bend DN 100, 15 °C, and can be either to the right or the left of the toilet basin.

CAUTION! Risk of damage!

Incorrect installation can result in damage.

• The distance between the middle of the wall-hung toilet and the unit may not be more than 350 mm, as otherwise malfunctions may occur.
• Therefore, do not use an additional connecting pipe between the toilet outflow bend and the unit.
• The middle of the toilet outflow must be 220 mm above the installation level of the unit.
• As well as a wall-hung toilet, the unit can be connected to a washbasin, a shower and a bidet; other connections are not permitted.
• The tank has one port for additional DN 50 HT pipes on each longitudinal side, located lower down, as well as two ports on the top of the tank.
• The elastic connecting sleeves supplied for connecting the outflow pipe simplify installation and are required for reasons of noise prevention.
• The inlet pipes from the shower and washbasin must be fitted with a bend (Fig. 4, Pos. 5) as close as possible to the unit, if they are connected to the low ports on the longitudinal sides.
• This bend must have a height of at least 180 mm between the bottom of the pipe and the installation level, in order to prevent sewage containing faeces from flowing back into the inlet pipe.
• Installing the lifting unit before covering the frame makes it easier to inspect the connections

Pressure pipe

The on-site pressure pipe (Fig. 4, Pos. 1) DN 25 or DN 32 (minimum clear diameter 28 mm) is connected via an S-shaped discharge elbow to the pressure outlet of the unit. The waste water pressure pipes may be made of PVC, PP or PE-HD.

Pressure pipe connection

• The pressure pipe should be laid without a fall. If laying it with a fall to the transfer point is unavoidable, a wider pipe should be laid from the highest point in order to prevent a lifting effect and associated malfunctions (Fig. 4, Pos. 2 and Fig. 6-3).
• Fasten the 1 ¼” non-return valve with a 40 x 1 ¼” adapter directly to the S-shaped pressure pipe elbow, so that the water flowing back after the pump is switched off is reduced to a minimum and the valve can be easily accessed through the inspection opening during maintenance (Fig. 6-1).

Tank ventilation

CAUTION! Risk of damage!

• Incorrect installation can result in damage.
• Improperly installed tank ventilation can cause malfunctions.
• The tank must be ventilated in order for the unit to work properly.

Tank ventilation

The ventilation insert can be positioned as in Fig. 4, Pos. 3 and Fig. 7. The filter insert can also be fed upwards or sideways through the front wall.

Fitting the tank ventilation

The tank is ventilated (Fig. 8) through an on-site HT pipe DN 50, which connects the ventilation insert (supplied) or a ventilation pipe through the roof to the unit. The unit is supplied with an active carbon filter which reduces smells in the ventilation insert. Before installation, remove the foil. To change the active carbon filter, simply remove the ventilation grille from outside.

• Always have the electrical connection performed by a qualified electrician.
• For installation in bath and shower rooms, observe the relevant local regulations [e.g. VDE 0100 Part 701 in Germany].

The unit is delivered ready to plug in and may only be connected to standard safety sockets.

• The current type and voltage of the mains connection must correspond to those stated on the name plate,
• Mains fuse: 10 A, slow-blow
• Earth the unit according to the regulations.

Mains connection

Position of the safety socket

There are two options for positioning the safety socket:

1. Within the front wall installation, behind the cover of the maintenance hatch (Fig. 11, Pos. 1). The inspection hatch must be opened in order to respond to an alarm by pulling out the mains plug.
2. Outside the front wall installation, near the maintenance hatch (Fig. 11, Pos. 2). There is immediate access to the main plug for responding to an alarm or switching off the unit in an emergency.

Installing the safety socket

For installation outside the front wall installation, a flushmounted cavity wall socket with a cut-out base is required (Fig. 12). It is covered with a commercially available cooker socket from any manufacturer. When the insert for the cooker socket is removed, the mains plug can be passed through for initial connection and maintenance.

**Switching diagram

2. Ventilation pipe
3. Inlet for wall-hung toilet
4. Inlet pipe for shower/bidet
5. Inlet pipe for washbasin

Buoyancy protection

The DrainLift XS-F cannot be flooded, which means the installation site must be secure against flooding. EN 12050- 3 requires that sewage lifting units must be protectedagainst buoyancy (Fig. 15). Place the unit in the installation room and align it to the pipes to be connected. Use a long 10 mm stone bit to drill a marking just above the tank (not above the detachable hood), so that the hanger bolt to be mounted later will touch or only have a slight gap to the tank.
After drilling, take the unit out of the maintenance hatch and finish drilling the hole. Then put in the wall plug. Only fit the hanger bolt after you have installed the system.

Preparing the connecting ports of the unit

Open the connecting ports for the drainage fixtures in addition to the wall- hung toilet (shower, washbasin and / or bidet) and for the ventilation ports using a 40 mm hole saw (Fig. 16). Then deburr the holes.

CAUTION! Risk of damage! Remove the cut-out circle; do not leave it in the tank.

Shower inlet non-return valve (not permitted in Germany)

The 40 mm non-return valve supplied (Fig. 17) is inserted in the lower inlet opening of the shower connection via the guide grooves until it snaps in.
CAUTION! Risk of malfunctions!
Malfunctions will occur if the valve is incorrectly fitted

• The valve hinge must face upwards (check the condition on delivery).
• The valve must open towards the inside of the tank.

Emergency drain connection

NOTE : The PVC hose with plug supplied can be attached to the tank for simple draining in emergencies (Fig. 23). Drill the 13 mm port on the bottom of the tank with a spiral drill (max. Ø 9 mm) (Fig. 18). Push in the hose and fasten it with the hose clip (1.5 Nm tightening torque). Make sure that the drain opening of the hose is securely sealed with the plug.

Mounting the connecting sleeves

Before installing the unit, fasten the DN 50 and DN 100 connecting sleeves to the inlet pipes using the clips (supplied) (Fig. 19).
Make sure they are correctly seated and do not leak.

Installing the unit

Place the unit in the room where it is to be installed, line it up and fit the hanger bolt for buoyancy protection. Then fit theconnecting sleeves to the tank ports using the clips. Fit the discharge elbow between the pressure pipe and the pressure outlet of the unit and fasten it with the clips (Fig. 20). Make sure all clip connections they are correctly seated and do not leak.

Prohibited substances

Attach the sticker warning of prohibited substances (Fig. 21).
Attach the sticker supplied showing instructions (symbols) for the user of the toilet somewhere clearly visible, for example above the toilet lid or on the inside of the toilet lid.

CAUTION! Risk of damage! Putting in prohibited materials can cause malfunctions, damage the unit and invalidate the warranty.
