INTRODUCTION OF THE INHALATION EXPOSURE SYSTEM (IES): The Inhalation Exposure System (IES) is an instrument manufactured by Glas-Col that provides reproducible animal exposure to droplet-borne contaminates and infectious agents. It produces deep-lung infections that more closely simulate real-world circumstances. The system allows you to vary the concentration of airborne pathogens, the rate of airflow and the length of exposure, so experiments can be reproduced accurately.
UNPACKING: The Inhalation Exposure System is normally shipped via truck freight or by movers experienced in handling delicate equipment. 1. Open the door and carefully remove the contents of the chamber. Remove and discard empty cartons used as spacers and packing material wedged around the basket.
Figure 2. Nebulizer Connection EXTERNAL CONNECTIONS: Connect the power cable to a 3-prong, grounded 120v, 60Hz, or 240v, 50/60Hz (depending on model) AC voltage source. SPECIFICATIONS FOR EACH COMPONENT: LID: A 5/8" thick acrylic plastic lid, impervious to ultraviolet rays covers the chamber. Three latches provide sufficient pressure on the gasket to seal the lid to the tank.

BASKET: A stainless steel wire mesh basket, 10" in diameter by 8" deep, is provided. The basket is divided into two equal compartments. The basket lid is held with 2 thumb screws. Each basket compartment can hold approximately 10 to 15 mice. Basket must be inserted with baffle plate in this position.

NEBULIZER: An all glass nebulizer-venturi unit is provided for atomizing the suspension under pressure and combining with filtered air drawn in from the room to provide the proper mixture into the chamber. The nebulizer units are made as precise as possible. CONTROL VALVES: Panel mounted controls are provided for the compressed air and vacuum.
FUSES: The fuses are located on the right side of the unit. The fuses are labeled their amperage rating are listed as shown below: 099C A5212 MAIN POWER - 15.0 A VACUUM PUMP - 5.0 A INCINERATOR - 12.0 A ULTRAVIOLET LIGHTS - 1.5 A...
