WARNING ! WARNING
DO NOT WELD OR FLAMECUT any refrigerant line or vessel until all refrigerant (liquid and vapor) has been removed from chiller. Traces of vapor should be dis- placed with dry air or nitrogen and the work area should be well ventilated.
Refrigerant in contact with an open flame produces toxic gases.
DO NOT USE eyebolts or eyebolt holes to rig machine sections or the entire assembly.
DO NOT work on
LOCK OPEN AND TAG electrical circuits during servicing. IF WORK IS INTER- RUPTED, confirm that all circuits are deenergized before resuming work.
DO NOT siphon refrigerant.
AVOID SPILLING liquid refrigerant on skin or getting it into the eyes. USE SAFETY GOGGLES. Wash any spills from the skin with soap and water. If liquid refrigerant enters the eyes, IMMEDIATELY FLUSH EYES with water and consult a physician.
NEVER APPLY an open flame or live steam to a refrigerant cylinder. Dangerous over pressure can result. When it is necessary to heat refrigerant, use only warm (110 F [43 C]) water.
