system with an encapsulated delivery system. For the installation on

open delivery systems different MARTIN®installation consoles can

be used.

If installation conditions prove to be difficult, as is the case with im-

passable static components, or using the head drum as the tension

point, Martin Engineering or a representative can help with the posi-

tioning or find customized solutions.

1.2.2 Use in EX-protection areas

Under certain circumstances the product described here can also be

used in potentially explosive areas. Contact Martin Engineering for

more information on use in potentially explosive areas.

The use of the scraper in a device protection category that is higher

than that specified or under operating conditions other than those

specified by Martin Engineering is not permissible or may be done

only if Martin Engineering has granted its approval.

The use of the product mentioned here is allowed only within the

specifications given above. Using it in a higher than specified equip-

ment category or under operating conditions other than those

named and previously specified by Martin Engineering is considered

to be inappropriate use and can only be carried out if approved by

Martin Engineering.

If the MARTIN®D2H main scraper needs to be used for a different

purpose, then Martin Engineering or one of its representatives can

help with the product configuration.
