I 2.0 LIMITS AtID PRECAUTI0 tis 2.1 Equipment 2.1.1 The maximum number of compressor starts must not exce< i ten (10) per hour to avoid damage to the compressor and associated controls.
2.1.2 Never run a comprecsor without demineralized water - even when checking motor rotation.
Normal water prime in one-third to one-half a casing.
2.1.3 Never start a compressor when the water level is above the casing centerline.
