Series 651 Environmental Chamber 17
Installation
Environmental chambers are installed in load units using a mobile cart designed
for the chamber. The chamber is installed from the rear of the load unit.
Most of the environmental chambers have U-plugs. Removable sections (U-
plugs) in the top and bottom walls of the chamber allow the cart-mounted
chamber to be placed in position around the specimen and grips. Each U-plug
consists of two pieces, one stationary and the other removable. The front piece is
removed to install the environmental chamber after the specimen and all of its
instrumentation are installed in the load unit. When the specimen is ready to be
tested, the U-plugs are replaced.
Note The Model 651.05-02 and Model 651.04-01 Environmental Chambers
have no U-plugs. These units must be installed before the grips and
specimen are installed.
