8Hydraulic connection8.1.1 Installing the air vent valve under the roof Push long solar hose (40 in (1000 mm) Fig. 52, [2])onto the supply connection on the collector array andfix in place using hose clamp. Feed solar hose together with the sensor cablethrough the penetration (Fig. 52, [1]) and through theroof insulation.12Perform the same procedure with the return connection. Firmly screw R¾ hose fitting with O-ring (Fig. 52, [5])and double nipple with O-ring (Fig. 52, [3]) into the airvent (Fig. 52, [4]). Push hose fitting onto the solar hose as far as it willgo and fix in place using hose clamp (Fig. 52, [6]).6543NOTICEFor the return connection, you must installthe hose fitting and hose pipe adapter(from the connection kit) into the longsolar hose. Connect header pipe to the hose pipe adapter(Fig. 52, [3]).8.1.2 Installing the air vent valve on the roof Push short solar hose (4 in (55 mm)), Fig. 53, [1])onto the supply connection on the collector array andfix in place using hose clamp. Firmly screw R¾ hose fittings with O-rings(Fig. 53, [3]) into the air vent (Fig. 53, [4]). Insert hose fittings (Fig. 53, [3]) into the solar hoses(Fig. 53, [1] and [5]) as far as they will go, and fix inplace using hose clamps (Fig. 53, [2]). Insert hose fittings with compression ring(Fig. 53, [6]) into the solar hose as far as it will go,and fix in place with hose clamp. Feed solar hose together with the sensor cablethrough the penetration (Fig. 53, [7]) and through theroof insulation. Connect header pipe to the hose pipe fitting (¾ in (18mm)) (Fig. 53, [6]).NOTICEFor the return connection, you must installthe hose pipe adapter (from theconnection kit) into the long solar hose.63043965.60-1.SDFig. 52 Installing the solar hose to the supply connection1 Penetration2 Solar hose 40 in (1000 mm)3 Double nipple with O-ring4 Air vent body5 Hose fitting with O-ring6 Hose clamp71Fig. 53 Connecting the air vent valve on roof1 Solar hose 4 in (55 mm)2 Hose clamp3 Hose fitting with O-ring4 Air vent body5 Solar hose 40 in (1000 mm)6 Hose pipe adapter ¾ in (18 mm) with compression ring7 Penetration23 4352636Logasol SKN 3.0 - We reserve the right to make any changes due to technical modifications.
