SAFETY PRECAUTIONS
We at FBD are concerned about your safety. Please carefully read the following precautions before working with the
FBD553D unit. This will familiarize you with proper equipment handling techniques.
LIFTING
• To avoid personal injury or damage, do not attempt to lift the unit without help. The empty unit weighs
approximately 365 pounds (165 kg). The use of a mechanical lift is recommended.
• Use gloves to protect hands from being injured by the edges of cross bracing if lifting by hand.
• Use proper equipment and lifting techniques when lifting or moving equipment. The unit is top heavy.
Maintain unit in a vertical, upright position when lifting and positioning the unit.
ELECTRICAL
• This unit must be properly electrically grounded to avoid possible fatal electrical shock or serious
injury to the operator. The power cord is provided with a three prong grounded plug. If a three-hole
grounded electrical outlet is not available, use an approved method to ground the unit. Only qualified
electricians should perform this task and the work performed should meet all applicable codes.
• Always disconnect electrical power to the unit to prevent personal injury before attempting any
internal maintenance. Only qualified personnel should service internal components of electrical
wiring.
CARBON DIOXIDE (CO
2)
•CO2 (carbon dioxide) displaces oxygen. Strict attention must be observed in the prevention of CO2
gas leaks in the entire CO2 and soft drink system. If a CO2 gas leak is suspected, immediately
ventilate the contaminated area before attempting to repair the leak. Personnel exposed to high
concentrations of CO2 gas will experience tremors which are followed rapidly by loss of conscious-
ness and suffocation.
• To avoid personal injury and/or property damage, always secure CO
2 cylinders in an upright position
with a safety chain to prevent cylinders from falling over. Should the valve become accidentally
damaged or broken off, a CO
2 cylinder can cause serious personal injury.
