Install the new packing, (timer). Fasten the holder, (timer). Install the thermo-element with new O-ring. ! Before installing the thermo-element, press down the piston with the timer holder being installed to the head, (T=40-45N.m), and check that the piston returns up through the spring load. ! The standard thermo-element release temperature shall be 5-8 degC(41-46.4 degF). (Thermo-element released at 15-18 degC (59- 64.4 degF) is available as option. Take care not to mistake the specifications: see diagram below.) ! Do not pull out the piston housed in the thermo-element manually. If it is extracted manually, discard it since the re-use of the piston is no longer possible. !
Do not tighten the thermo-element with excessive tightening torque, (T=30-35N.m). ! Do not tighten t he cooling water plug with excessive tightening torque, (T=22-25N.m). ! Take care not to catch impurities in the seal washer. Install the holder with new O-ring, (timer).
