Caution
Never operate the machine if the safety and monitor-
ing devices have been removed or damage, or if they
do not work.
2.8. Pumped fluids
Each pumped fluid differs in regard to composition, cor-
rosiveness, abrasiveness, TS content and many other
aspects. Generally, our products can be used for many
applications. For more precise details, see chapter 3, the
machine data sheet and the order confirmation. It should
be remembered that if the density, viscosity or the gener-
al composition change, this can also alter many parame-
ters of the product.
Different materials and impeller shapes are required for
different pumped fluids. The more exact your specifica-
tions on your order, the more exactly we can modify our
product to meet your requirements. If the area of applica-
tion and/or the pumped fluid change, we will be happy to
offer supportive advice.
When switching the product into another pumped fluid,
observe the following points:
•
Products which have been operated in sewage or
waste water must be thoroughly cleaned with pure
water or drinking water before use.
•
Products which have pumped fluids which are haz-
ardous to health must always be decontaminated
before changing to a new fluid. Also clarify whether
the product may be used in a different pumped fluid.
•
With products which have been operated with a lu-
bricant or cooling fluid (such as oil), this can escape
into the pumped fluid if the mechanical shaft seal is
defective.
Danger - explosive fluids!
It is absolutely prohibited to pump explosive liquids
(e.g. gasoline, kerosene, etc.). The products are not
designed for these liquids!
2.9. Sound Pressure
Depending on the size and power (kW), the pump has
a sound pressure of about 40dB (A) to 70dB (A) during
operation. However, the actual sound pressure depends
on several factors. These are, for example, the type of
installation and set-up, mounting of accessories, piping,
operating point, immersion depth, and much more.
3. General description
3.1. Application
Compact automatic pump designed to remove conden-
sate water from furnace burners, gas or oil condensing
boilers, air conditioners, refrigeration display cabinets and
de-humidifiers where drainage by gravity is not possible.
Attention: Regulations of water authorities or other relevant au-
thorities must be obeyed when condensate is being disposed of.
Condensate from condensing boilers being operated with stan-
dard heating-oil (not low on sulphur) may not be disposed of into
the canalization without being neutralized. This is also true for
condensing boiler systems exceeding 200 kW.
Maximum liquid temperature should be 50°C.
3.2. Types of use
The condensate pump is designed for intermittent oper-
ation.
3.3. Construction
The condensate pump H76K consists of a collection tank
with a single phase motor and an integrated float switch,
3 inlets and pressure side connection with integrated back
water valve. An additional float switch activates a safety
switch with optional closing or opening contacts. A device
for wall mounting, 1.8 m of cable and 6 m of discharge
hose are also included.
