MAINTENANCE AND SERVICE INSTRUCTION
Always depressurise the system and rinse off the parts before beginning any
maintenance work. Use protective goggles.
Use tweezers and wear gloves which are sufficient for cryogenic applications.
Do not touch adjacent parts with unprotected hands. Rinse off the parts once
again before starting the “daily inspection”
DAILY INSPECTION
1. Inspect the coupling surface for cleanliness and corrosion.
2. Inspect the hose unit swivel for free rotation.
3. Inspect the tank- and hose unit for faultlessness and external signs of seizure.
REGULAR SERVICE
Regular service interval is very much depending on local regulations and application
conditions. If nothing else is specified and it is a new application with unknown parameters
we recommend to make a first service after 6 months and decide then depending on the
inspection result about further intervals.
The service procedure shall be as follows:
1. Exchange sealing and washer.
2. Check the hose unit ball bearing for faultlessness.
3. Replace worn or damaged components.
Check the state of the connection surface and verify that it is clean before proceeding with
the connection.
Couple the repaired unit to a serviceable hose or tank unit as appropriate and check for
correct operation of the valve actuating and bayonet locking mechanism. Couple and
uncouple the unit(s) several times.
USE ONLY ORIGINAL MANNTEK SPARE PARTS FOR MAINTENANCE.
NOTE! Both kits are needed when doing service.
Spare part kit (S-MC5C-xx)
Seal kit (O-MC5C-06V)
xx means the material key according to the product catalogue. You will find it also as the
7th and 8th sign in the serial number (e.g. MC563Cxx).
