STEP 1: Rooftop configuration

This picture shows how the rooftop configuration has to be before recovery module assembling No Hood No panel The lifting lug and the corner sheet metal have to be removed. FLEXYII_WSHP-IOM-0909-E The head guard on the left corner of the rooftop has to be flattened. Page 34

STEP 2: Lifting

For Recovery module lift, use lifting lugs localised at the top of each corner structures FLEXYII_WSHP-IOM-0909-E Page 35

STEP 3: Fitting

During installation phase, fit the support part on the interior level of the rooftop SUPPORT PART INTERIOR LEVEL FLEXYII_WSHP-IOM-0909-E Page 36

STEP 4: Check

A good fit can be controled by looking at the junction between the rooftop and the recovery module: The junction has to be at the same level. SAME LEVEL For 150 and 170 sizes, a deviation of 70mm exists between rooftop and recovery module Size 150 & 170 (see picture on the right). 70 mm In the same…

STEP 5 : Fixing

When the module is well fitted, fix the corner structures to the rooftop by using selfdrilling screws 32mm Self-drilling screws 32mm D4.8 And fix the top of the module to the rooftop by using self-driling screws 19mm Self-drilling screws 19mm D6.3 FLEXYII_WSHP-IOM-0909-E Page 38

STEP 6: Masticate

Apply mastic on side junctions and higher junction FLEXYII_WSHP-IOM-0909-E Page 39

STEP 7: Electrical wiring
