14. Installation of shelf boards and samples (Do not put samples directly on the
bottom of the chamber.)
The models DNF301/401/411 and DNF601/611 have two shelf boards
One of those boards is screwed to the lowest shelf rung on the shelf pillar inside at the time of
factory shipping.
Put other shelf boards to places you want in the bath.
Placing the sample directly on the bottom of product may disturb the air circulation and make
the normal temperature control difficult, resulting in burn of the sample by abnormal
temperature and fire. Always place the sample on the shelf plate and never place it directly on
the bottom.
Do not use the shelf plates other than dedicated ones. Otherwise normal temperature control
cannot be achieved.
