INSTALLATION OF UNIT EDK 22/25 - The tubes (coolant and condensate) can be brought out on the left-hand or right-hand sides. In the case of the coolant tubes,it is necessary to drain the Gas and Liquid from the tubes at point 3 and to re-weld the tubes in the required configuration.
Location of the Indoor Unit CAUTION: The indoor units are supplied with a dry nitrogen charge at a pressure of 0.3MPa - The indoor unit is designed for installation in a double ceiling supported by four anchor points used to attachment and leveling.The diameter of screws for installation of indoor unit :maximum 18mm, minimum 10mm.
REFRIGERANT PIPING - Outdoor unit on an upper level. - Fit a siphon on the Gas line every 5m - Outdoor unit on an lower level. H E AT P U M P - F o r ONLY models ,provide a trap at the base of the column (Gas line) in this case of installation.
PIPES TO BE MADE ON SITE - This operation should be performed expertly by qualified professionals (refrigeration engineer) (brazing,vacuum,charge,etc...). As the bulb is close to the tubes to be brazed,it is recommended that the bulb is protected by covering it with a damp cloth during brazing.
