, and tighten equally in diagonally opposite pairs to
ensure that the diaphragm retainer held firmly in place.
Note: Tighten three times to 5Nm with a torque driver to prevent damaging the cross

(15) Place the pump head gasket and pump head cover on the pump head in that order,
and tighten the six hexagon socket head cap screws (M5 x 16L) equally in diagonally
opposite pairs to 5Nm with a torque wrench.
