Zanussi Electrolux ZRB 291 W Instruction Book page 19

Fit the refrigerator door to the upper door hinge pin (d)
then slightly tilting both doors fit the pin of the double
door hinge (m) into the left drill of the refrigerator door.
Opening both doors fix the double door hinge onto the
left side using the screws (2 pieces) (c). Do not forget to
replace the plastic spacer (b) under the hinge. Be
careful that the door edges are parallel with the edge of
the mantle.
Put the appliance to its place, set it level, and apply
voltage to it.
In case you do not want to perform the procedures above,
call the nearest brand-mark service.
Technicians will accomplish the refitting expertly for charge.
