9. MAINTENANCE AND REPAIR
9.1. MAINTENANCE
Periodical checks recommended by GCE should be done at least annually
by the provider of the product. This should include leakage and functional
tests of TU.
• Proceed with functional and leakage tests as described in chapter 6.2.
If any leakage or damage is found, use procedure described in chapter
9.2.
• Clean TU from possible contamination.
• Check the presence and status of the labels. In case of bad legibility,
contact GCE or distributor of GCE products.
Use only original spare parts.
All sealing and o-rings must be stored by provider or operator in a dry,
dark and clean storage during the complete lifetime.
9.1.1. PERIODICAL EXCHANGE OF COMPONENTS
TU variants for Air800 or N2 intended for use of running the surgical tools
must have some components (o-ring in quick coupler) exchanged every
three years. Please contact service for exchange (chapter 9.2).
All TU variants (including the above mentioned) must have some compo-
nents (quick coupler, check valve of TU, spring, o-rings in housing of TU
exchanged every ten years. Please contact service for exchange (chapter
9.2).
9.1.2. SEAL TYPE IDENTIFICATION
By servicing, repairing or replacing of internal components of the terminal
unit (H), it is easy to identify whether it is a version with internal O-ring seal
or a version with metal-to-metal seal. After removing the button (B), cover
(C) and quick coupling (D), a set of markings is visible on front surface of
terminal unit. In addition to the gas type, the batch number and the data
code, there is an indication which type of seal is used inside. Marking „S“
(as Soft) means O-ring seal, marking „M“ (as Metal) means metal-to-metal
seal.
9.2. REPAIR
Service, repair and spare parts exchange can only be done by a person
that has the appropriate certifi cates according to the required national
standards and laws for mounting and repairs of concerned gas medical de-
vices. Standards valid for such installations and testing are ENISO7396-1
