WARNING
Sudden and irreversible tissue damage can result from freezing. Wear gloves and
face protector or safety glasses in any situation where skin or eye contact with
refrigerant is possible.
Compressor lubricating oil used in this equipment is caustic. Wear gloves and a face
protector or safety glasses in any situation where skin or eye contact is possible. If oil
contacts skin, wash with soap and water.
Dangerous chemical refrigerant under pressure is used in this equipment. Use great
care to avoid contact with liquid refrigerant. Work in a well ventilated area. Heat may
cause the refrigerant to decompose and release irritating, toxic, and corrosive gases.
Prevent contact of refrigerant with flame or hot surfaces.
Approved hearing protection must be worn when operating the MTRCS diesel
engine. Failure to observe this precaution may result in severe and permanent
hearing loss.
NOTE
Refrigeration system repairs must be performed by a technician certified to perform
such duties in accordance with EPA restrictions. Performing repairs without proper
certification may be a violation of public law and subject to severe penalties.
Test the integrity of the filter-drier as follows:
1. Start refrigeration unit and operate in cool mode for 30 minutes (TM 10-8145-222-10, Operating Procedures).
2. Physically feel liquid line inlet (Figure 1, Item 1) and outlet (Figure 1, Item 2) connections of the filter-drier
cartridge (Figure 1, Item 3).
If outlet side feels warmer than inlet side, filter-drier does not require changing.
If outlet side feels cooler than inlet side, replace filter-drier per this WP.
3. Install top-left panel (WP 0013, Install).
