1.3 Installation
The MS-40 has been designed as a completely self-contained portable leak
detector and therefore has the capability to work in a wide range of
environments. However, before installation in a work area, certain
requirements must be met.
• A properly grounded electrical supply (115V/60Hz/10A,
230-240V/50Hz/5A, 100V/50Hz/10A, or 100V/60Hz/10A as
labeled on rear of unit) must be available for the unit.
• A user supplied helium supply is usually necessary for the unit
(but not for all testing, e.g., sealed parts should already be pre-
bombed with helium). The MS-40 can use either a Mass 3 or
Mass 4 helium supply. Virtually any standard purity helium
may be used during leak testing. Depending on the type of leak
testing that will be performed, a spray probe (for vacuum
testing), a sniffer assembly (for sniff testing) or a test cup (for
pressure bombing testing) will be necessary. All of these items
are available directly from Vacuum Instrument.
• The recommended ambient temperature range for the unit is
from 10°C to 40°C. Also, excessively humid environments
should be avoided.
• Depending upon the immediate environment, an external
exhaust facility may be necessary. A bulkhead is installed on
the rear of the MS-40 that is intended for user-provided 3/8”
polyflow tubing. Note that the bulkhead is not connected to the
internal exhaust filter of the unit but must be connected by the
User. The tubing is then attached to a functional exhaust system.
WARNING!
Only qualified service personnel should operate the unit when either
the front or rear panels are open. Potentially lethal high voltages are
continually applied to the circuit boards and other areas within the
unit during its operation. Although these areas are shielded and well
marked, failure to follow this precaution may possibly lead to severe
injury or death.
