All equipments are tested at the manufacturer. Any warranty claims will cease if any modication is executed
on the equipment without prior consent of the manufacturer.
For any claim acceptance the following conditions shall be fullled:
• The rst commissioning of the equipment must be done by a technician trained or authorized by the
manufacturer or by a professional partner.
• Only trained and professionally skilled staff shall carry out any maintenance work
• Original spare parts may be used only.
• All the maintenance works must by carried out in regular terms.
NON OBSERVANCE OF THESE CONDITIONS WILL CAUSE LOSS OF WARRANTY AND ITS TERMINATION IN CONSEQUENCE.
The unit can be easily switched off through a sepatate ON/OFF level on the integrated display.
System installation must be executed in line
with Machinery Safety Directive No.: (98/37/EC),
Low Voltage Directive (73/23/EEC), Directive on
Electromagnetic Compatibility (89/31/EEC), and it
should meet the common rules which are in force for
technical applications, and should comply with the
corresponding national regulations as well.
!WARNING
The equipment must be grounded. Any maintenance
or installation work carried out on the live equipment
parts, in any case, may not be carried out if the
equipment is connected to the electric power supply
utility.
!WARNING
Equipment is under pressure!
Any gas discharging is dangerous and may lead to
accidents.
!CAUTION
The user is responsible exclusively for equipment
operation and employment, and for necessary intime
maintenance execution ,in the given extent, and in
line with this manual, by means of professional staff.
!CAUTION
The equipment must be situated in dry area on
suitable, and horizontal footing.
Temperature in this area may not drop under zero
point, as we can prevent only in this way any water
circuit freezing.
!WARNING
The system is unable to absorb any mechanical load
applied by components installed externally. Such
additional load may cause incorrect operation or
damage to the equipment, or may cause accidents.
There is a loss of all warranty rights in such case, at
the same time.
!WARNING
The packaging must be disposed in line with the
law being in force. The manufacturer delivers the
equipment in recyclable wrappingmaterials and so it
minds environmental protection.
It is compulsory to follow the instructions presented
in this manual, because in case of any consequential
damage, occurred in consequence of unprofessional
manipulation, all the warranty terms granted will
cease. The contents of this manual, and of any
other document delivered with this equipment, is the
manufacturers proprietorship.

Warning
For this operation execution an electric heating rod
must be installed into the service water tank!
IMPORTANT!
With normal use, and regular hot water consumption,
no measures against Legionellas are necessary
to take because the service water tank is heated
regularly!
By this Time program activation, however, you may
carry out a cyclic bacteria removal from the service
water tank.
Highlight one day per weak for this purpose, in
compliancewith the description mentioned above, by

MAINTENANCE
!WARNING
Never let the cooling media drain freely out to
the atmosphere during system discharging.
Use appropriate scavenging tool for cooling
medium exhaustion. Any cooling mediumyou
must provide to the supplier for its professional
disposal.
!WARNING
Ensure professional disposal of the old
compressor-oil. Hand it over to the supplier for
this purpose.
The old compressor oil never dispose together
with other used oils (like engine oil etc.).
Prior to maintenance work start, study the safety
instructions, presented in this manual, carefully !
Responsibility for regular and in-time execution of
any works, in connection with maintenance, bears
the equipment operator. The equipment operator
may sign an agreement on maintenance execution
with a local service provider. If it comes to equipment
damage, in consequence of a botched up repair, all
the granted warranty rights will cease.
This service manual is valid for standard equipment
only, and it does not contain any maintenance works
to be done on modied equipment components.
Maintenance intervals
The maintenance should be carried out by qualied
personnel exclusively according to he following table
for maintenance execution. All detected shortages
must be xed.
Cooling medium lling-in
The cooling medium must be lled-in to the system
in liquid form, that insures the lling-in process
correctness.
For equipment lling-up we can use the valve on the
suction side of the compressor, as well as the valve
installed to the pipe for liquid.
Any insufcient lling-in may evoke losses in
performance and maylead to low pressure failure
which evokes switch-off of the whole system.
However, any equipment overlling will lead to hot
gas temperature increase, and so to needlessly high
power consumption. Beside this, it can cause a high-
pressure failure, when all the equipment is switched
out too.
Compressor
The compressor is equipped, from the manufacturer,
by oil lling necessary to its operation. Under
common operation conditions the oil lling may
hold in the system for the whole lifetime of the
equipment . As far as it is not necessary to carry out
any repairs on the system, no oil relling is required.
Any compressor replacement may be done only by
authorised servicing partner.
General requirements
The system is designed for continuous run and so it does not require any regular servicing.
(See the following table)!
