ENGLISH

The pump must only be connected 

to outlets that are installed accord-

ing to specifications and are protected with at 

least 10 A (slow) and FI-safety switches 

(30mA).

APPLICATION

Submersible pumps from the US se-

ries are suitable for pumping domestic 

waste water without stones. 
When using the pumps, the relevant na-

tional laws, regulations and stipulations 

must be adhered to, for example:

   

∙ Domestic contaminated and waste 

water (e.g. EN 12056 in Europe)

   

∙ Installation of low voltage systems  

(e.g., VDE 0100 in Germany)

For non-standard utilisation conditions, 

further regulations must be observed 

(e.g. VDE 0100 in Germany, part 701: 

bathrooms and shower rooms; part 

702: swimming pools and fountains and 

part 737: outdoor use).
Where no explosion protection is stipu-

lated for the pumping of foul wastewa-

ter at the installation location, US 75, 

US 105, US 155 may also be used.

Modes of operation

with the pumped medium at a tempera-

ture of 104°F (40°C) or 194°F (90°C) 

in the case of HE and HES hot water 

pumps:
Motor submersed: continuous opera-

tion S1 

Motor at the surface: short duration 

operation S2; see “Technical Data” 

Motor at the surface; intermittent op-

eration S3; see “Technical Data”
The submersible pump is frost-resistant 

down to -20°C when stored in dry condi-

tions. When installed, however, it must 

not be allowed to freeze in the water.

Transport

The pump must always be lift-

ed by the handle and never by 

the power supply cable! The 

pump should only be lowered into deep-

er chambers or pits using a rope or 

chain.

ELECTRICAL  

CONNECTION

Only qualified electricians may 

carry out electrical works to 

the pump or the controls. 

The relevant standards (such as EN 

standards), country-specific regula-

tions (such as VDE in Germany), and the 

regulations of the local power supply 

companies must be observed.

Attention ! 

Never put the mains plug or 

a free lead end in water! If water gets 

into the plug, this can cause malfunc-

tions and damage.
Observe the operating voltage (see the 

type plate)!  
The pump is provided with a wind-

ing thermostat. In case of unaccept-

ably high temperatures it switches off 

the pump to protect it against possible 

damage. Unacceptably high tempera-

tures may result e.g. from dry running 

or mechanical or electrical overload.  

The pump is switched on again 

automatically after cooling 

down - risk of injury! For this 

reason, always disconnect the device 

from the mains before remedying the 

fault! In order to do this, unplug the 

pump from the mains supply or remove 

the pre-fuses of the pump controls!

US 62 to US 105

Observe the operating voltage (see the 

type plate)! Only connect the pump to 

sockets that have been installed prop-

erly in accordance with the regulations 

and are fitted with a 16 A (delay) fuse.
Pumps without built-in level control can 

also be operated automatically through 

the use of our level controls. Our ready 

to connect level controls can be in-

stalled without specific electrotechnical 

skills.

US 151 to US 253

Observe the operating voltage (see the 

type plate)! Only connect the pump to 

sockets that have been installed prop-

erly in accordance with the regulations 

and are fitted with a 16 A (delay) fuse.
The pump must only be operated with 

the standard motor protection plug. 

Models without motor protection plug 

must only be operated using the level 

controls with integrated motor pro-

tection that are approved by JUNG 

PUMPEN. These pumps must be con-

nected by a qualified electrician.
