Operation Manual for heat exchangers

10. Responsibilities of user

There are a number of requirements for the user. These include, but are not limited to:
• amend local rules and regulations of accident prevention and environmental protection to the manual that are not included in the norms.
• expand the manual to local languages
• train and instruct personnel
• assure that relevant regulations, specification and law are adhered to
• assure that the unit is installed professionally
• The device, equipments and all exchange parts must be disposed of properly and according to environmental regulations. Regional laws are to be
respected.

11. Installation instructions

To make the installation as easy as possible, the unit includes a cut-out schematic that shows all openings for air entry and outlet as well as mounting
holes.
The unit has to be hooked up by a licensed electrician.
During installation, pay attention that the openings for the air inlet and outlet are completely open. The provided gasket has to be used around the cut-
outs to ensure leak-tightness between the cabinet and the unit.
To allow for unrestricted drainage of the condensate out of the air conditioners, all units without condensate evaporation are equipped with a hose that
guides the condensate through the floor panel. For further guidance of the condensate, a hose (10mm inner diameter) can be connected.

12. Commissioning / Start-up

The unit may only be commissioned by trained personnel. All relevant local laws and regulations have to be adhered to.
Damages that result from improper installation void the warranty.
During installation the cabinet has to be completely without power.
Thoroughly inspect the unit for damages and test the functionality.
The unit must be installed upright – deviations of more than 5% can impair the functionality and damage the unit.
The cabinet has to be sealed to IP 54 (per EN 60529) or higher. If this cannot be achieved, the desired interior cabinet temperature may not be reached
and a disproportionally high amount of condensate may occur.
The connection between the cabinet and the air conditioner has to be sealed air-tight.
Voltage, frequency and fuses have to be provided per the technical data listed on the type plate of the unit.

13. Water quality

The cooling medium (water, refrigerant etc.) may not be contaminated with coarse- or corrosive particles. In cases of severe contamination a filter must
be implemented.
With a flow temperature of less than 10°C, glycol must be mixed with the coolant. This causes the device to lose power.
When water is implemented for cooling, it is recommended that the following hydrological data must be complied with as far as possible:
Hydrological data
pH-value
Carboxylic acid
free carbonic acid
aggressive carbonic acid
Sulfides
Oxygen
Chloride ions
Sulfate ions
Nitrates und Nitrites
COD
Ammonia
Iron
