Inspecting the Heaters
Venting
Standard Driers vent to room air and no special venting is required. If special
venting is desired, a vent adapter is available as an option (see Figure 2.4).
The vent requires a four-inch (10-cm) hose. Connect the hose to the vent adapter
using a standard hose clamp, then connect the opposite end of the hose to a hospital
exhaust vent at normal atmospheric pressure.
Figure 2.4 Optional vent adapter
Inspecting the Heaters
If a sterile drier fails to heat, a heater might have come loose during shipping.
Model 43 Driers have two heaters; Model 44 Driers have four heaters.
Required Items:
Heater (part no. 401572)
1.4-in. Nut Driver
To check the heater:
1Press the power switch to the OFF (O) position, and then unplug the power
cord.
2Remove the upper white door seal and loosen—but do not remove—the screws
just inside the Drier door, behind the door stop (see Figure 2.5).
Optional vent adapter
(back or side)
NOTE
#
If removing the heaters, ensure that the proper voltage and wattage heater is replaced into
the correct socket. For example, place the 500-watt heater in the Model 44 120V~ Drier in
the right plenum nearest the blower; the three 400-watt heaters fill the remaining sockets.
For proper operation and correct locations, see the wiring diagrams appropriate for the
device’s electrical configuration (see Appendix A).
