SPECIAL SERVICE INSTRUCTIONS
There are rare occasions when the refrigerant charge must be evacuated from a case in order to perform service work. In
those situations, Federal Industries recommends that the refrigerant charge be evacuated into a recovery system to prevent
the possibility of hydrofluorocarbons (HFC’s) from being released into the atmosphere.
If moisture or liquid is observed around or under a Federal Industries case, an immediate investigation should be made by
qualified personnel to determine the source of the moisture or liquid. The investigation made should determine if the case
is malfunctioning or if there is a simple housekeeping problem.
Moisture or liquid around or under a case is a potential slip/fall hazard for persons walking by or working in the general
area of the case. Any case malfunction or housekeeping problem that creates a slip/fall hazard around or under a case
should be corrected immediately.
