Installation, Operating, and

Maintenance Instructions

SAFETY CONSIDERATIONS

Positive pressure storage systems are designed to

provide safe and reliable service when operated

within design specifications. When operating this

equipment, use good judgment and safety precau-

tions to avoid damage to equipment and property

or injury to personnel.

Installation, start-up, and servicing of this equip-

ment can be hazardous due to system pressures,

electrical components, and equipment location

(roofs, elevated structures, etc.). Only trained,

qualified installers and service technicians should

install, start up, and service this equipment.

Be sure you understand and follow the procedures

and safety precautions contained in this guide.

DANGER

Failure to follow these procedures will result in severe per-

sonal injury or death.

DO NOT VENT refrigerant relief valves within a building.

Outlet from rupture disc or relief valve must be vented out-

doors in accordance with the latest edition of ASHRAE 15

(American Society of Heating, Refrigerating, and Air Con-

ditioning Engineers). The accumulation of refrigerant in an

enclosed space can displace oxygen and cause

asphyxiation.

PROVIDE adequate ventilation in accordance with

ASHRAE 15, especially for enclosed and low overhead

spaces. Inhalation of high concentrations of vapor is harm-

ful and may cause heart irregularities, unconsciousness, or

death. Misuse can be fatal. Vapor is heavier than air and

reduces the amount of oxygen available for breathing.

Product causes eye and skin irritation. Decomposition

products are hazardous.

DO NOT USE OXYGEN to purge lines or to pressurize a

machine for any purpose. Oxygen gas reacts violently with

oil, grease, and other common substances.

NEVER EXCEED specified test pressures, VERIFY the

allowable test pressure by checking the instruction litera-

ture and the design pressures on the equipment nameplate.

DO NOT USE air for leak testing. Use only tracer gases

and dry nitrogen.

DO NOT VALVE OFF any safety device.

BE SURE that all pressure relief devices are properly

installed and functioning before operating any machine.

WARNING

Failure to follow these procedures may result in personal

injury or death.

DO NOT USE TORCH to remove any component. System

contains oil and refrigerant under pressure.

To remove a component, wear protective gloves and gog-

gles and proceed as follows:

a. Shut off electrical power to unit.

b. Recover refrigerant to relieve all pressure from sys-

tem using both high-pressure and low pressure ports.

c. Traces of vapor should be displaced with nitrogen

and the work area should be well ventilated. Refrig-

erant in contact with an open flame produces toxic

gases.

d. Cut component connection tubing with tubing cutter

and remove component from unit. Use a pan to catch

any oil that may come out of the lines and as a gage

for how much oil to add to the system.

e. Carefully unsweat remaining tubing stubs when nec-

essary. Oil can ignite when exposed to torch flame.

DO NOT USE eyebolts or eyebolt holes to rig machine

sections or the entire assembly.

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 heater 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 servic-

ing. IF WORK IS INTERRUPTED, confirm that all cir-

cuits are deenergized before resuming work.

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 any enters the eyes,

IMMEDIATELY FLUSH EYES with water and consult a

physician.

NEVER APPLY an open flame or live steam to a refriger-

ant cylinder. Dangerous overpressure can result. When

necessary to heat refrigerant, use only warm (110 F [43 C])

water.

DO NOT REUSE disposable (nonreturnable) cylinders or

attempt to refill them. It is DANGEROUS AND ILLE-

GAL. When cylinder is emptied, evacuate remaining gas

pressure, loosen the collar and unscrew and discard the

valve stem. DO NOT INCINERATE.
