Insert the piston assembly in the cylinder assembly.

Place the two locking plates, pos. 334, as shown,

and place the spring holder, pos. 335.

Note: Check the locking plates for burrs. If present,

remove them.

Assemble the locking plates and spring holder with

the M6 cylinder screws, pos. 336.

Tighten to 14 Nm. Add Loctite to the screws before

assembly.

After adding Loctite to the used end thread on the

M8 stay, pos. 325, mount the four stays in the flange.

Mount a threaded spindle in the piston spindle, pos.

324.

Mount one end plate, pos. 328, for adjustment of the

cylinder, pos. 327, so that the plate catches the circu-

lar cutouts in the cylinder. Then remove the plate,

pos. 328, for a while.

Note: Check the end plates for burrs. If present, re-

move them.

Mount the spring, pos. 337, and the two piston

plates, pos. 328, as follows:

Turn the lower plate, as seen in the previous picture,

and the upper one 90 degrees so that it will hit the

upper surface of the cylinder between the cuts

mentioned.

Mount the tool, and press down the spring.

Add Loctite to the threads, and mount the nuts, pos.

326.

Tighten to max. 20 Nm. Take care that the end plate

does not bend too much. Remove the tools.

Secure the spindle, pos. 324, with the circlip, pos.

329, and mount the O-ring, pos. 331. Make sure the

circlip has hit the groove.

Mount the check valve assembly, pos. 323, and pos.

318/319/320. Tighten M6 to 14 Nm.

The valve cartridge is now ready for mounting.

The valve insert must be installed so that the hole

pointing out is in a position that allows the tempera-

ture transmitter, pos. 827, to be there.

Mounting of filter cartridge

In old valve houses, a circlip must be added in a

groove as a stop for the inner cover, pos. 316. In

new houses, a stop is machined in the house.

Mount the suction filter, pos. 317, on the inner cover,

pos. 316, with the two cylinder screws (M8x16) pos.

322, and tighten to 20 Nm.

Once the O-ring, pos. 312, has been added to the in-

ner cover, carefully pull in the filter cartridge in the

suction house, pos. 300.

Mount the cover, pos. 315, and tighten the bolts

(M16) to 147 Nm.
