Installation
CAUTION: READ SECTION 6 ENTITLED "BATH USE "before placing
the bath in service. Incorrect handling can damage the bath and void the
warranty.
This bath is not designed to be portable. Therefore, moving the bath once it has
been installed should be kept to a minimum.
CAUTION: Never move a bath that is full of fluid. This action could be
extremely dangerous and could result in personal injury to the person
moving the bath.
If the bath is going to be placed in an area where it will need to be moved fre-
quently, a special cart can be designed to accommodate the bath making the
bath much more portable. Hart sells carts designed for these baths. However,
even with a cart the bath should not be moved full of fluid. The fluid can splash
causing injury or if the bath and cart tip, the fluid could cause damage to the
surrounding area and personal injury to personnel.
If the bath must be moved, be sure to drain the fluid to prevent any injury. The
side of the bath with the compressor is heavier than the tank side. To safely
move the bath, two people are required.

Bath Environment
The Model 7012 Bath is a precision instrument which should be located in an
appropriate environment. The location should be free of drafts, extreme temper-
atures and temperature changes, dirt, etc. The surface where the bath is placed
must be level.
If used at higher temperatures where fluid vaporization is significant, a fume
hood should be used.
5.2
"Dry-out" Period
Before initial use, after transport, and any time the instrument has not been en-
ergized for more than 10 days, the bath will need to be energized for a
"dry-out" period of 1-2 hours before it can be assumed to meet all of the safety
requirements of the IEC 1010-1.
