2 Safety Instructions
2.1 General
These installation and operating instructions are a part of the
product, and contain basic information that must be observed
during installation, operation and maintenance. For this reason,
the installer and specialist personnel or operators must read
these instructions prior to set-up.
Please observe both the general safety instructions listed
under section 2 and the special safety instructions detailed in
the other sections.
A copy of the EC Declaration of Conformity is provided with
these instructions. This declaration shall be deemed void in the
event of a modification that has not been agreed with us.
2.2 Identification of notes in the operating instructions
General hazard symbol
Warning! Danger of personal injury!
Observe the relevant accident
prevention regulations.
Warning! Danger from electrical
voltage! Prevent hazards arising from
electrical energy. Observe
the instructions in local or general
regulations (e.g. IEC, VDE, etc.), and
those of the local energy supplier.

Manual
HE OEM 2 | 40-XX | 60-XX
This symbol indicates useful information
for handling the product. It indicates
potential diculties and aims to ensure
safe operation.
Signs attached directly on the product, such as:
• direction of rotation arrow
• type plate
• identification of connections must be strictly observed and
kept in an easily legible state.
2.3 Personnel qualification
The personnel used for mounting, operation and maintenance
must have relevant qualifications. Areas of responsibility and
monitoring of personnel must be guaranteed by the
owner/operator. If personnel do not have the necessary
know-how, they must be trained or instructed
accordingly. This device can be used by children at or above
the age of 8 years, as well as by persons with reduced physical,
sensory or mental capabilities, or who lack experience and
knowledge, if they are supervised or have been instructed
concerning the safe use of the device and if they understand
the hazards arising from its use. Children may not play with the
device. Cleaning and maintenance operations may not be
carried out by children without supervision.

2.4 Danger of not observing safety instructions
Not observing the safety information can endanger persons,
the environment and the system. Not observing the safety
instructions shall result in the loss of any and all claims to
warranty.
Potential dangers include:
• Hazards to persons through electrical and mechanical eects.
• Failure of important system functions.
• Hazard to the environment from escaping fluids resulting
from a leak.
• Failure of prescribed repair and maintenance work.
2.5 Safety-conscious working
Observe the safety instructions detailed in this manual, along
with the current national accident prevention regulations.
Should the system operator also have their own internal
regulations, these must also be observed.
2.6 Safety instructions for the operator
• Any existing touch guard protecting moving parts may be
neither removed nor shut down while the system is in
operation.
• In the event of a fluid leak, any fluids must be collected or
diverted in a way that prevents hazards to persons and the
environment from arising.

Manual
HE OEM 2 | 40-XX | 60-XX
• Prevent hazards arising from electrical energy.
• Observe the instructions in local or general
regulations (e.g. IEC, VDE, etc.), and those of the
local energy supplier.
• In the event of hazards arising from the system due to
contact with hot or cold parts, these parts must be fitted
with a touch guard.
• Keep flammable substances away from the product.
2.7 Safety instructions for installation and maintenance work
The system operator is responsible for ensuring that all
installation and maintenance work is carried out by qualified
personnel. These persons must also have familiarised
themselves in advance with the product using the operating
instructions. Conducting work on the pump is only permitted
when the system is shut down.
Ensure that the device is securely disconnected from the
power supply. Disconnect the device plug to achieve this.
Prescribed instructions for shutting down the device can be
found in the operating instructions. All protective mechanisms,
such as a touch guard, must be correctly reattached after work.
2.8 Unauthorised conversion and production of spare parts
Modification or conversion of the product is only permitted
after prior consultation with the manufacturer. Only use
original spare parts for repairs. Only use accessories that have

Manual
HE OEM 2 | 40-XX | 60-XX
been approved by the manufacturer. The manufacturer shall
bear no liability for any consequences resulting from the use of
other parts.
2.9 Unpermitted operation
If the pump is disconnected from the power supply, wait at
least 1 minute before reactivating. Otherwise, the pump's
inrush current limit has no eect, which can lead to functional
errors or damage to any connected heating controller. The
pump's operational safety can only be ensured
if it is used as intended. Please observe section 4 of
these operating instructions here. Ensure compliance
with the limit values detailed in the technical data.
3 Transport and Storage
After receiving the product, inspect it immediately for damage caused in transport. Should you
detect any transport damage, assert a claim with the haulier.
Incorrect transport and storage can lead to personal injury or damage to the product.
• Protect the product against frost, moisture and damage during transport
and storage.
• Only carry the pump by the pump housing, and never by the connection cable
or terminal box.
• If the packaging weakens due to moisture, this can lead to the pump falling
out and causing severe injury
 Intended use
These high eciency pumps are designed to circulate hot water in central heating
systems and are also suitable for pumping low density liquids in industrial and
commercial applications They are also suitable for solar installations
