Intended Use
Olympic Driers are intended to rapidly dry pasteurized medical equipment,
primarily respiratory therapy and anesthesia parts. The Drier should be used after
disinfection by pasteurization or liquid chemical means.
Sterile-Driers are not intended for storing or warming solutions.
Description
Sterile-Driers use HEPA filtered, heated air to dry parts. The additional filtering
reduces the risk of contamination.

220-230V~, 50 Hz, 9A
220-230V~, 60 Hz, 9A
Assembly
This device must be connected directly to a properly grounded hospital-grade
electrical outlet.
Due to amperage draw, Model 44 requires a dedicated over-current protection device.
Supply voltage fluctuations are not to exceed 10% of the nominal supply voltage.
Only qualified technicians should assemble the device.
To assemble the Drier:
1 After uncrating, install the leveling feet, then carefully stand the drier upright.
2 Clean the metal surfaces with soap and water or liquid disinfectant. Clean the
plastic doors with soap and water.
Never use alcohol to clean the doors, as alcohol will damage the Plexiglas®.
3 After the Drier is in place, adjust the leveling feet (see Figure 2.1).

NOTE

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.
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.
