Algorithm for shortening Freshpoint 160-E (Pro) L055/07/1 units

If the wall thickness is equal to the value L of your product, you may start with the step 1 of the unit mounting instruction. If the L value of your product is greater than the wall thickness, it may be shortened before installation. You may take the following actions: Identify the exact wall thickness in the product installation site. The shortening length for the product is equal to the difference between the L value of the product and wall thickness.

• Shorten the external coating.
• Shorten the extension node spigot for the same length as the external coating.
• Put the second stabilizing coupling on the shortened spigot an fix it using adhesive aluminum tape at least 10 mm away from the spigot cut. min 10 mm
• Insert the shortened extension node inside the external coupling to join the air flow distributing node.

To shorten the condensation heater, do the following:

• The condensation heater is installed in the operation module, not dismountable. Position the working module vertically on the table. Using nippers, remove a piece of the condensation heater of the same length value that was used to shorten the spigots.
• Using a knife, remove the external cable coating 10-15 mm long. Remove the shielding on the segment using nippers. Make a cut in the heater-resisting material as shown in the figure.
• To insulate the heater and make the cut airtight, use the insulating tube with an adhesive layer (included in the delivery set). Put on a 30-mm long section of it. Fit it using an industrial dryer. Press the overlapping part with pliers.
