DO NOT REUSE disposable (nonreturnable) cylinders or attempt to refill them. It
is DANGEROUS AND ILLEGAL. When cylinder is emptied, evacuate remaining
gas pressure, loosen the collar, and unscrew and discard the valve stem. DO NOT
INCINERATE.
CHECK THE REFRIGERANT TYPE before adding refrigerant to the machine. The
introduction of the wrong refrigerant can cause machine damage or malfunction.
Operation of this equipment with refrigerants other than those cited herein should
comply with ANSI/ASHRAE-15 (latest edition). Contact Carrier for further informa-
tion on use of this machine with other refrigerants.
DO NOT ATTEMPT TO REMOVE fittings, covers, etc., while machine is under pres-
sure or while machine is running. Be sure pressure is at 0 psig (0 kPa) before
breaking any refrigerant connection.
CAREFULLY INSPECT all relief valves, rupture discs, and other relief devices AT
LEAST ONCE A YEAR. If machine operates in a corrosive atmosphere, inspect the
devices at more frequent intervals.
DO NOT ATTEMPT TO REPAIR OR RECONDITION any relief valve when corrosion
or build-up of foreign material (rust, dirt, scale, etc.) is found within the valve
body or mechanism. Replace the valve.
DO NOT install relief devices in series or backwards.
USE CARE when working near or in line with a compressed spring. Sudden
release of the spring can cause it and objects in its path to act as projectiles.
