g. Door Operation with Liquids Cycle.
(1) Allow ample cooling time to prevent possible thermal shock or liquids
boiling over when the door is opened or when the load is removed. After a complete
cycle, check to ensure that the chamber pressure gauge is at zero. Failure to observe
this warning when sterilizing a liquid load may cause violent agitation of the liquid. This
may result in the liquid boiling over or flasks exploding.
(2) Wear an elbow length heat resistant glove to protect you against
escaping residual steam when you lower the verti-glide door. After the liquids cycle has
completed, lower the verti-glide approximately one inch from the top for the residual
steam to escape. After 15 minutes, carefully remove the flasks. Be careful not to
agitate the load.
h. Wire Sizes. The sterilizer uses the following five applications for wire sizes
and types.
(1) A high voltage supply (120 volts alternating current (vac) or greater) is
used for pumps which are in excess of 1/4 HP. These wires are marked with red letters
and are at least 16 American wire gauge (AWG).
(2) Ground wires (protective and functional) are required by code to be 16
AWG. Although both protective and functional earths may be the drain wire for the
shielded cables, protective earths have a G/Y insulation, while functional earths have a
black insulation.
(3) Neutral wires are 16 AWG. These wires are marked as NEUT (neutral)
in black letters. The one exception is the 14 AWG wire located in the power box.
(4) The 120v control lines are 18 AWG with red lettering. The one
exception to this is the 14 AWG wire located in the power box.
(5) Low voltage control lines (less than 30v) are 16 AWG with violet
lettering. On some models, wires terminating at the control board are 18 AWG.
