1.2 Damage Requiring Service
Disconnect the product from all power sources and refer servicing to Qualified Service Personnel
under the following conditions:
a. When any cable or plug is damaged.
b. If any liquid has been spilled onto, or objects have fallen into, the product.
c. If the product has been exposed to rain or water.
d. If the product does not operate normally even if you follow the operating instructions. Adjust
only those controls that are covered by the operation instructions. Improper adjustment of other
controls may result in damage and will often require extensive work by a qualified technician to
restore the product to its normal operation.
e. If the product has been dropped or the enclosure has been damaged.
f. When the product exhibits a distinct change in performance. This indicates a need for service.
Do not substitute parts or modify instrument.
Because of the danger of introducing additional hazards, do not install
substitute parts or perform any unauthorized modification to the product.
Return the product to a service facility designated by Granville−Phillips for
service and repair to ensure that safety features are maintained. Do not use this
product if it has unauthorized modifications.
Proper Grounding:
All components of a vacuum system used with this or any similar high voltage
product must be maintained at Earth ground for safe operation. The power
cord of this product shall be connected only to a properly grounded outlet. Be
aware, however, that grounding this product does not guarantee that other
components of the vacuum system are maintained at Earth ground.
Complying with the usual warning to connect the power cable only to a properly
grounded outlet is necessary but not sufficient for safe operation of a vacuum
system with this or any similar high voltage producing product.
Verify that the vacuum port to which the Mini−Convectron Gauge is mounted
is electrically grounded. It is essential for personnel safety as well as proper
operation that the envelope of the gauge be connected to a facility ground. Use
a ground lug on a flange bolt if necessary.
Replacement Parts − When replacement parts are required, be certain to use
the replacement parts that are specified by Granville−Phillips or that have the
same characteristics as the original parts. Unauthorized substitutions may
result in fire, electric shock or other hazards.
Safety Check − Upon completion of any service or repairs to this product, ask
the Qualified Service Person to perform safety checks to determine that the
product is in safe operating order.
