AquaEdge® Water-Cooled, Custom-Design Centrifugal Chiller Unit 17DA | Safety and Maintenance Instructions

DANGER

• DO NOT USE OXYDEN to purge lines or to pressurize a machine for any purpose

• NEVER EXCEED specified test pressures

• DO NOT VALVE OFF any safety device

• BE SURE that all pressure relief devices are properly installed and functioning before operating any machine.

WARNING

• DO NOT USE eyebolts or eyebolt holes to rig machine sections or the entire assembly

• NEVER OPERATE an open-drive machine, pumpout unit or other equipment without coupling (or belt) guards in place.

• DO NOT work on high voltage equipment unless you are a qualified electrician

• DO NOT WORK ON electrical components, including control panels, switches, starters, or oil heaters until you are sure ALL POWER IS OFF and no residual voltage can leak from capacitors or solid-state components

• LOCK OPEN AND TAG electrical circuits during servicing, IF WORK IS INTERRUPTED, confirm that all circuits are deenergized before resuming work

• DO NOT syphon refrigerant by mouth

• AVOID SPILLING liquid refrigerant on skin or getting it into eyes. USE SAFETY GOGGLES.

• NEVER APPLY an open flame or live steam to a refrigerant cylinder.

• DO NOT REUSE disposable (nonreturnable) cylinders nor attempt to refill them

• CHECK THE REFRIGERANT TYPE before charging machine

• DO NOT ATTEMPT TO REMOVE fittings, covers, etc. while machine is under pressure or while machine is running.

• CAREFULLY INSPECT all relief valves, rupture discs and other relief devices AT LEAST ONCE A YEAR.

• DO NOT ATTEMPT TO REPAIR OR RECONDITION any relief valve when corrosion of build-up of foreign material (rust, dirt, scale, etc.) is found within the valve body or mechanism. Replace the valve.

• DO NOT VENT refrigerant relief valves within a building: vent to outside.

• DO NOT install relief valves in series or backwards

• USE CARE when working near or in line with a compressed spring.

CAUTION

• DO NOT STEP on refrigerant lines

• DO NOT climb over a machine

• USE MECHANICAL EQUIPMENT (crane, hoist, etc.) to lift or move inspection covers or other heavy components.

• DO NOT WELD OR FLAME CUT any refrigerant line or vessel until all refrigerant has been removed from the vessel

• BE AWARE that certain automatic start arrangements CAN ENGAGE THE STARTER

• DO NOT VENT OR DRAIN water boxes containing industrial brines, liquid, gases or semisolids without permission of your Process Control Group

• DO NOT LOOSEN water box cover bolts until the water box has been completely drained

• DOUBLE CHECK that coupling nut wrenches, dial indicators or other items have been removed before rotating any shafts

• DO NOT LOOSEN a packing gland nut before checking the nut has a positive thread engagement

• PERIODICALLY INSPECT all valves, fittings and piping for corrosion, rust, leaks, or damage

• PROVIDE A DRAIN connection in the vent line near each pressure relief device to prevent a build-up of condensate or rain water.
