SQ253 Valve Combination 4.4 Condensate separator The condensate separator consists of a glass bulb, lower and upper cover plates in stainless steel each with a connection opening and O-rings between the glass bulb and covers. Since the condensate vessel is blown out with each flushing process, no maintenance work is required. When replacing the various parts, it should be ensured during assembly that the four threaded bolts with hexagon nuts are tightened evenly and that the O-rings are correctly seated. If any leaks occur: • First, slightly, but evenly tighten the threaded bolts. • Check the glass bulb for any damage. • Check the O-rings. Copyright ® SIEMENS Page 70 04/04
SQ253 Valve Combination 4.5 Four-way ball valve The 4-way ball valve is constructed in steel with an electrical actuator drive to DIN ISO 5211/3337. The ball valve material is complete in PEEK. The full sealing tightness is achieved by a pressure-aided, maintenance-free sealing system. The actuator drive is also maintenance-free and fitted with an anti-blocking motor with temperature monitoring. 4.5.1 Removing the 4-way ball valve • Remove inside the housing of the 4 Way-valve. Loosen the 2 screws inside the valve box and remove the valve from the drive. Note: Attention must be paid to the connecting cable. This is so long that the complete unit can be lifted out. 4.5.1.1 Checking the limit switches: • Remove the complete unit as described above. • Check the position of the 4 limit switches • The control is provided by the OP3 in the control cabinet. • A selected position is approached by entry in the CTR 16 (e.g. Measure). • Assembly takes place in the reverse sequence. Important! When setting the limit switches, pay attention to the 24VDC control voltage. Copyright ® SIEMENS Page 71 04/04
