Notice on Maintenance
Service Information
General Work Area
Inform others working in the immediate vicinity about the nature of the work being performed. Avoid working
in confined spaces. Section off the area around the workspace. Ensure conditions within the area are safe by
removing potentially flammable material.
The manual contains specific information for service personnel who will perform maintenance on the product.
Ventilated Area
Ensure the area is adequately ventilated before opening the system or performing any refrigerant work.
Maintain adequate ventilation while working. Effective ventilation will safely disperse any released refrigerant
into the atmosphere.
Refrigeration Equipment Checks
Ensure all electrical components are compatible with the product and built to the correct specifications. Follow
manufacturer maintenance and service guidelines at all times. When in doubt, consult the MRCOOL

Technical
Department, at [phone], for assistance.
If using flammable refrigerants, conduct the following checks:
1. Ensure ventilation machinery and outlets are operating adequately and are not obstructed.
2. If an indirect refrigerating circuit is being used, check the secondary circuit for the presence of refrigerant.
3. Check that equipment markings are visible and legible. If they are not, replace with markings that are legible.
4. Ensure refrigeration pipe or components are installed in a position where they are unlikely to be exposed to
any substance which may corrode refrigerant containing components, unless the components are
constructed of materials which are inherently resistant to corrosion, or are suitably protected against
being corroded.
Electrical component repair and maintenance should include initial safety checks and component inspection
procedures.
DO NOT connect the circuit to an electrical supply If a fault exists that could compromise safety.
It must be corrected before the circuit can be connected.
