CAUTION
ZKH 20
is a pump for lifting condensation water from an air
conditioning system, a condensation boiler or from refrigeration
units. Include a neutralisation device if necessary (see the
manufacturer’s instructions for your boiler).
The pump starts automatically and has a high level of
performance, safety and reliability provided that all the
installation and maintenance instructions described in this notice
are strictly followed.
Please take particular note of the information marked by :
« » Indication that a risk of electrical origin exists,
« » Instructions for use only by qualified professionals.
ZKH 20
contains a pump. The tank of the
ZKH 20
is fitted with a
float which controls the operation of the motor. When the
condensates enter the tank, the pump starts up.

INSTALLATION
ZKH 20
has wall fixings.
The unit should be easy to access for testing and
maintenance.
The unit must be installed level. Adjust the installation
using a spirit level before fixing the unit.
Make sure that the equipment is protected from damp while ins-
talling it.

CONNECTION AT THE COVER INLET
The unit has 1inlet 28 mm in diameter. To connect the water to be
drained off, connect the water inlet to one of the inlets. If neces-
sary, use the rubber adaptator
X 19, 32, 40 mm.

CONNECTING TO THE DISCHARGE PIPE
The
ZKH 20
discharge pipe must be connected to the flexible
hose
(supplied : length 5 m). This hose should be used to form
the vertical section of the discharge pipe. A
• Place the flexible hose onto the non-return valve of the
ZKH 20
(see diagram
5
b
).
• Position the flexible hose in the most vertical position
possible to avoid it kinking.
• It is advisable to make a smooth bend to avoid the hose
kin-king.
The
ZKH 20
is fitted with a non-return valve to prevent re-
activation.
ELECTRICAL CONNECTION
The electrical installation should be carried by a qualified person.
The unit should be connected to a fully earthed electrical
supply. All wiring must conform to BS7671, 1992 requirements for
electrical installations. The
ZKH 20
requires a 220/240V single
phase AC 50 Hz supply (UK specification).
The condensate pump power plug must be easily accessible.
Check whether the earth resistance is lower than 38
Ω
.
Protect the condensate pump via an RCD with a rated response
current of not more than 30 mA.
5c
ALARM
ZKH 20
is fitted with a detection system that can
trigger an alarm if the water level rises too high
(audible or visual alarm, 1.5V to 230V), see diagram
5c
:
1
. Brown wire: shared wire
2
. Black wire: normally off
3
. Blue wire: normally on
To fit the alarm, connect the blue and brown wires
of the alarm to the respective terminals on the
ZKH 20
.
