Safety Information; Condensate Drainage - KORADO KORAFLEX Variant F2V Instructions D'installation

SAFETY INFORMATION

• Trench heater operating voltage = 24 V DC.
• Fan operating voltage = 24 V DC, control voltage 0 - 10 V DC.
• IP rating: IP 20.
• Electrical installation design must be carried out by suitably qualified person in accordance with the relevant standards.
• Trench heater installation must be carried out by persons with the relevant technical qualification.
• Prior to commisioning the electrical components must he thoroughly inspected in accordance with relevant standards of the respective country.
The user is obliged to provide regular inspections of all electrical components in the periods given by relevant standards of the respective
country.
• ALL WORKS ON THE ELECTRICAL EQUIPMENT WITHIN THE MEANING OF STANDARDS OF THE RESPECTIVE COUNTRY MUST BE
CARRIED OUT BY RELEVANTLY QUALIFIED PERSONS DULLY ACQUINTED WITH THE RESPECTIVE EQUIPMENT.
• Trench heaters must be disconnected from power supply before commisioning and before all maintanance works.
• Disconnect all trench heaters out of operation for a longer time (eg. in summer) from power supply.
• Trench heaters are designed for dry environment.
• The producer will not be held responsible to any defects, caused by installing these trench heaters in humid environments (swimming pools,
conservatories...).
• Electrical wiring must be carried out according to the trench heater electrical diagram.
• Fix the input power cord.
ALTERATIONS OF THE PRODUCT
• No changes and technical alterations of the products are allowed without prior consultation and approval of the producer. Unauthorized
alteration can have a negative impact on function and safety of the product.
• When handling the product, avoid any steps not given by the Installation instructions provided.
• Do not add any 230 V AC power supply into the trench heater.
CONNECTION TO HYDRAULIC SYSTEM
• Connection ½ G".
• We recommend to connect the trench heater to the hydraulic system using the lockshield and thermostatic valve.
• Bleed the system and check it for leakages.
• Carry out the leak test.
• Protect the system from freezing.

CONDENSATE DRAINAGE

• Where F2V and F4V trench heaters are used for cooling, the condensate will occure on the heat exchanger, depending on cooling medium
temperature and on humidity and temperature in the room.
• F2V and F4V trench heaters are equipped with a canal for condenstate drainage. Connect the drainage hose to the drainage pipe (D=18mm) on
the drainage tank. Fasten the hose by a clip and check for leakage.
• F2V 11/20 condensate drainage pipe leads to the window, F2V 13/34, F4V 13/34 to the side.
• Minimal condensate drainage pipe gradient must be greater than 2 % with no interruptions or rising sections.
• Where possible, equip the drainage pipe with a U-bend to prevent odour.
• Check the drainage system for leakage before concreting.
