1. WehoPuts miniature wastewater
treatment plant – general
1.1 General
The WehoPuts miniature wastewa-
ter treatment plant is a bio-chemical
domestic wastewater treatment
system intended for year-round use.
All wastewater is directed into the
treatment plant without separate
pre-treatment. Treated water then
fl ows or is pumped to the discharge
point.
Further information on the point
and manner of discharge must be
received from the local environmen-
tal authorities before installation.
The WehoPuts treatment plant
has been designed to suit a certain
number of persons and quantity of
wastewater (calculated based on
150l/person/day).
If household water is taken from a
private well, its quality must meet
the general recommendations to
secure good operation of the treat-
ment plant.
Information on the function of the
WehoPuts treatment plant is avail-
able from the display in the plant
control unit and the signal lamp on
the machine room ventilation pipe.
NOTE! The signal lamp must be
monitored carefully. When the signal
lamp is on, the treatment plant is
functioning normally. When the
light is fl ashing or has gone out, the
treatment plant has a malfunction
and the message on the control unit
display must be checked immedi-
ately!
To simplify plant operation
monitoring, the WehoPuts 5 and 10
treatment units off er an optional
GSM modem allowing for treatment
plant remote monitoring using GSM
phones. The GSM modem must be
specifi ed when ordering the treat-
ment plant, as well as the need to
use more than one GSM phone.
The WehoPuts treatment plants
have a 2-year warranty starting
from the purchase date. The war-
ranty covers structural, manufactur-
ing and material errors reported to
and verifi ed by the manufacturer.
Detailed warranty conditions can
be found in the warranty certifi cate
supplied with the treatment plant.

1.2 Operational safety
The tank lid must always be care-
fully locked.
Only the electrical con-
nections and cleaning
process control proce-
dures specifi ed in the installation
and operation manual may be
performed during maintenance.
When fi lling the chemical container
and handling the chemical pump,
the corrosiveness of the chemicals
used (pH 2) must always be taken
into account. Therefore, special
protective equipment such as rub-
ber gloves and protective glasses
must be worn. The safety data
sheet must be studied in advance.
The treatment plant is equipped
with device-specifi c automatic
fuses and ground fault switches.
Treatment plant grounding is done
through the building’s main distri-
bution board.
NOTE! The control box casing may
only be opened by a professional
electrician.
1.3 Foreign material and debris
in wastewater
Normal household wastewater,
such as domestic water and toilette
fl ushing water, is directed into the
treatment plant.
Debris washed down with waste-
water may clog or damage the
treatment plant pumps and stop
the entire treatment process. To
ensure the disturbance-free op-
eration of the plant, the following
materials and items must not be
fl ushed down with wastewater:
•
bottle caps and other small
metal items
• cigarette
butts
