SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can be hazardous due
to system pressure and electrical components. Only trained and qualified
service personnel should install, repair, or service air-conditioning
equipment.
Untrained personnel can perform basic maintenance functions of cleaning coils
and filters and replacing filters. All other operations should be performed by
trained service personnel. When working on air-conditioning equipment, observe
precautions in the literature, tags and labels attached to the unit, and other
safety precautions that may apply.
Follow all safety codes, including ANSI (American National Standards
Institute) Z223.1. Wear safety glasses and work gloves.
Use quenching cloth for unbrazing operations. Have fire extinguisher available
for all brazing operations.
It is important to recognize safety information. This is the safety alert
symbol ****. When you see this symbol on the unit and in instructions or
manuals, be alert to the potential for personal injury.
Understand the signal words DANGER, WARNING, CAUTION, and NOTE. These words
are used with the safety-alert symbol.
DANGER identifies the most serious hazards which will result in severe
personal injury or death. WARNING signifies hazards which could result in
personal injury or death. CAUTION is used to identify unsafe practices, which
may result in minor personal
injury or product and property damage. NOTE is used to highlight suggestions
which will result in enhanced installation, reliability, or operation.
WARNING
Electrical shock can cause personal injury and death. Shut off all power to
this equipment during installation and service.
There may be more than one disconnect switch. Tag all disconnect locations to
alert others not to restore power until work is completed.

- Verify the correct hail guard part number is provided for the desired rooftop unit size. See Table 2, “Package Usage,” on page 2.
- The units associated with this hail guard kit are shipped with a center post located on the end of the unit. It should have been removed during unit installation. This post is located approximately 1.5 ft from the left corner post on the end of the unit. Remove this post if it has not been removed already.
- Insert plastic inserts into both corner posts (6 inserts) and center post (2 inserts) located by the control box as indicated in Fig. 3.
- Align the hail guard panel with the respective section of the outdoor coil and insert the top edge of the panel under the lip of the top cover.
- Use the long 7/8 in. gasketed screws to secure the hail guard in the plastic inserts (8 locations). Use the shorter serrated screws to secure the panels to the remaining holes in the vertical direction. Use shorter serrated screws to secure the panels along the bottom of the panels.
