Procedure for installation and insulation assembly
(only for 2” to 4” sizes)
1. Remove the two black head covers at the ends.
2. Open the two side sections and the lower cap.
3. Install the separator in the system.
4. For cooling applications, consider using a silicon caulk
or sealant by spreading a thin layer of sealant over
surfaces A and B.
Wait for the solvent to evaporate (approx. 10 minutes).
Note that once the sealant dries it may be difficult to
remove the insulation shell in the future without
destroying portions of the insulation.
5. Reassemble the two side sections, fitting the lower cap
into one of the two sections and then connecting the other.
6. Finish the assembly with the adhesive tape provided in the box.
7. Complete with the two black head covers.
8. Fit the automatic air vent and the drain valve.
