INSTALLATION, OPERATION AND DISASSEMBLY/
REASSEMBLY PROCEDURE FOR ANTI-CORROSIVE
CYLINDER SERIES 435 CONFORMING TO ISO 6431
FEATURES
Anti-corrosive type CIX cylinders are designed for use in
aggressive environments:
• Chemical, saline or humid atmospheres
• Food processing industries, such as dairy, cheese mak-
ing and meat processing environments: high resistance to
lactic acid.
STORAGE
The cylinder must be kept in its original packaging as long
as it is left unused. Do not remove the protective covers
from the ports.
STORAGE CONDITIONS
- protected from exposure to weather;
- temperature : -40°C to +80°C
- relative humidity: 95 %
After storage at low temperature, the cylinders must gradu-
ally be brought to room temperature prior to pressurisation.
OPERATING CHARACTERISTICS
• Air quality
- air or neutral gas ≤ 50 µm
- min. dew point: - 5°C
• Max. pressure: 10 bar.
Excess static pressure of 15 bar allowed once for 1 s.
• Fluid and ambient temperature: -10°C to +80°C
(with/without position detector)
• Position detector: PVC cable 0,3 m + stainless steel
screw-type external connector Ø M12, 3 pins, IP69K
(PNP), cat. no.: PNP-QDS-M12-F
• Lubricants
This type of cylinders can be operated with or without lubri-
cated air. However, once the cylinder is used in a lubricated
air circuit, lubrication must be maintained throughout the
cylinder's lifetime.
- Oil quality: non-detergent oil, without aggressive additives.
- The use of silicone-based lubricants is prohibited.

PUTTING INTO OPERATION
• The cylinders can be mounted in any position.
• These cylinders are NOT guiding units.
Any constraint on the rod will shorten their performance
and lifetime.
• Speed for optimum life: ≤ 1 m/s
• Max. allowable speed: 2 m/s (at 20°C)
• Adjustable pneumatic cushioning:
- Captive adjustable cushioning screws
CAUTION
Cumulating aggressive operational conditions, such as
max. pressure, min. temperature, will diminish the products'
performance.

CLEANING
CIX type cylinders are designed to withstand high-pressure
wash-downs and bactericidal additives. Metal brushes or
objects that may impair the surface fi nish of the cylinders
(Ra = 0,6) must not be used for cleaning.
MAINTENANCE
WEARING PARTS
(Z1)
Disassembly
1- Unscrew the front and rear covers.
2- Remove the rod/piston unit from the cylinder barrel.
(Be sure to note the mounting direction of each
seal)
3- Carefully remove the lip seals (5).
4- Remove all other seals from the covers (1),(2),(3) and (4).
5- Clean the rod, piston, the inside of the barrel and all seal
grooves (do not use corrosive agents or solvents).
6- Do not disassemble the piston.
Reassembly
For best results, it is recommended to use grease spe-
cifi cally designed for lubrication in the food industry.
1- Lightly coat the lip seals and the piston grooves with
grease.
2- Insert the lip seal into the piston groove (fi g. A).
Observe correct mounting direction.
3- Insert the seal with a circular movement using a fl at tool.
(fi g. B)
4- Check the correct position of the seal (fi g. C).
5- Assemble the 2nd seal by repeating points 2,3 and 4.
Observe correct mounting direction (see fi g. D).
6- Lightly coat the outside and inside of the piston (*) and the
entry of the barrel with grease.
7- Place the piston diagonally into the bottom part of the bar-
rel (fi g. E).
8- When inserting the piston into the barrel, take care not to
damage the lip seals with the internal threads on the ends
of the barrel.
9- Use a fl at tool to push the lip seal with a circular
movement into the cylinder (Fig. F). Do not use a
screwdriver.
10- Place the piston back into the barrel (fi g. G).
11- Lightly coat the seals, scraper (1), rod seal (2), O-rings
(4), cushioning seals (3) and their grooves in the covers
with grease.
12- Place seals (1), (2), (3) and (4) into their respective
grooves and observe correct mounting direction.
13- Check the external threads on the covers and the inter-
nal threads on the barrel for cleanliness (including lack of
grease).
14- Lightly coat the external threads on each cover with Loc-
tite 542® and screw the covers by hand into the barrel
until they reach their mechanical stop.
