Installation and operating instructions Wilo-Drain TMT 32M 31
INSTALLATION English
Eitherapressurehoseoranexistingdischarge
pipeline is connected to the pressure side.
Ifthemotoremergesduringoperation,the
following operating parameters must be strictly
observed:
• The max. uid temperature and ambient tem-
perature is 75°C.
• Non-immersedoperatingmode:S325%
BEWARE of burns!
The housing parts can heat up to above
100°C. There is a risk of burns! After switch-
ing it off, let the pump cool down to ambient
temperature.
Discharge pipeline connection
NOTE
The pump is only held in place here by the pip-
ing. All vibrations and torques are transferred to
the pipe system!

Work steps
1. Preparingpumps:about1h
• Connectthepipeelbowtothepressureport
usingthethreadedange/angeconnection.
2. Installingthepump:about1-2h
• Oncethepipeelbowhasbeenconnected,posi-
tion the pump at the pressure pipe. If neces-
sary,secureliftingequipmenttothepumpwith
ashackle,liftthepumpandthenlowertothe
intendedlocation(sump,pit).
• Screw the pipe elbow onto the existing dis-
charge pipeline.
• Route the power supply cable in such a way
that it cannot be damaged.
• Have the electrical connections made by a
qualiedelectrician.
3. Commissioningthepump:about1-3h
• Asdescribedinthe“Commissioning”section
Connecting a pressure hose
RISK of pressure hose becoming separated!
Uncontrolled separation or movement of the
pressure hose can result in injuries. Secure the
pressure hose appropriately. Prevent buckling
of the pressure hose.
Work steps
1. Preparingpumps:about1h
• Fitthepipeelbowtothepressureconnection
using the hose connection.
• Fastenthepressurehosetothepipeelbow
with a hose clip.
2. Installingthepump:about1-2h
• Position pump in installation location. If neces-
sary,secureliftingequipmenttothepumpwith
ashackle,liftthepumpandthenlowertothe
intendedlocation(sump,pit).
• Checkthatthepumpisverticalandonasolid
bearing surface.
Avoid sinking.
• Route the power supply cable so it cannot be
damaged.
• Have the electrical connections made by a
qualiedelectrician.
• Route the pressure hose so that it is not
damaged and fasten it at certain points (e.g.
outow).
3. Commissioningthepump:about1-3h
• Asdescribedinthe“Commissioning”section
5.3.3. Level control
Filllevelscanbedeterminedusingthelevel
controlsystem,meaningthepumpisswitchedon
andoffautomatically.Thelllevelcanberecord-
edusingoatswitches,pressureandultrasound
measurements or electrodes.
Notethefollowinginformation:
• Whenusingoatswitches,ensurethattheycan
move freely in the operating area!
• The water level must not fall below the minimum!
• The maximum switching frequency may not be
exceeded!
• Ifthelllevelsuctuatestrongly,thenalevel
control should be made on two test points as
standard. This means larger differential gaps are
reached.
Installation
Forcorrectinstallation,pleaseseetheinstallation
and operation instructions for the level control
device.
Observe the information on the maximum
switching frequency and the minimum water
level!
5.4. Dry-running protection
Toensurethenecessarycooling,thepumpmust
beimmersedwheninoperation,dependingon
theoperatingmode.Inaddition,makesurethat
no air enters the hydraulics housing.
The pump must therefore always be immersed
intheuiduptothetopedgeofthehydraulic
housingor,ifapplicable,uptothetopedgeof
themotorhousing.Foroptimumoperational
reliability,werecommendinstallingadry-running
protection system.
Correctrunningisensuredbyoatswitchesor
electrodes.Theoatswitchorelectrodeisxed
in the sump and switches off the pump when the
water level falls below the minimum coverage
level. If the dry-running protection only includes
oneoaterorelectrodeandthelllevelsdeviate
signicantly,thenthepumpmayturnonand
off constantly! This can result in the maximum
