Installation, Operating, and

Maintenance Instructions

SAFETY CONSIDERATIONS

Positive pressure storage systems are designed to pro-

vide safe and reliable service when operated within

design specifications. When operating this equipment,

use good judgment and safety precautions to avoid dam-

age to equipment and property or injury to personnel.

Installation, start-up, and servicing of this equipment

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-

Conditioning 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 de-energized 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.

INTRODUCTION

The 19XR Positive Pressure Storage (PPS) system has been

designed to help owners and operators of positive pressure

chillers store HFC-134a refrigerant during service and repair

work. The 19XR system conserves this refrigerant and pre-

vents the release of excessive amounts of refrigerant into the

WARNING

CHECK THE REFRIGERANT TYPE before transferring

refrigerant to the machine. The introduction of the wrong

refrigerant can cause damage or malfunction to this

machine.

Operation of this equipment with refrigerants other than

those cited herein should comply with ASHRAE 15 (latest

edition). Contact Carrier for further information on use of

this machine with other refrigerants.

ENSURE that refrigerant is only pumped to or stored in

tanks that are ASME (American Society of Mechanical

Engineers) certified for the pressures appropriate to the

refrigerant being handled.

DO NOT ATTEMPT TO REMOVE fittings, covers, etc.,

while machine is under pressure or while machine is run-

ning. Be sure pressure is at 0 psig (0 kPa) before breaking

any refrigerant connection.

CAREFULLY INSPECT all relief devices, 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 device when corrosion or build-up of foreign

material (rust, dirt, scale, etc.) is found within the valve

body or mechanism. Replace the device.

DO NOT install relief devices in series or backwards.

USE CARE when working near or in line with a com-

pressed spring. Sudden release of the spring can cause it

and objects in its path to act as projectiles.

CAUTION

Failure to follow these procedures may result in personal

injury or damage to equipment.

EQUIPMENT should be operated by certified personnel

only.

DO NOT STEP on refrigerant lines. Broken lines can whip

about and cause personal injury and damage to the

machine.

DO NOT climb over a machine. Use platform, catwalk, or

staging. Follow safe practices when using ladders.

USE MECHANICAL EQUIPMENT (crane, hoist, etc.) to

lift or move inspection covers or other heavy components.

Even if components are light, use such equipment when

there is a risk of slipping or losing your balance.

BE AWARE that certain automatic start arrangements

CAN ENGAGE THE STARTER. Open the disconnect

ahead of the starter in addition to shutting off the machine

or pump.

USE only repair or replacement parts that meet the code

requirements of the original equipment.

DOUBLE-CHECK that coupling nut wrenches, dial indi-

cators, or other items have been removed before rotating

any shafts.

DO NOT LOOSEN a packing gland nut before checking

that the nut has a positive thread engagement.

PERIODICALLY INSPECT all valves, fittings, and piping

for corrosion, rust, leaks, or damage.

DO NOT MIX REFRIGERANT from chillers that use dif-

ferent compressor oils. Compressor damage can result.

(Cautions continued in next column.)

CAUTION

DO NOT re-use compressor oil or any oil that has been

exposed to the atmosphere. Dispose of oil per local codes

and regulations.

DO NOT leave refrigerant system open to air any longer

than the actual time required to service the equipment. Seal

circuits being serviced and charge with dry nitrogen to pre-

vent oil contamination when timely repairs cannot be

completed.

atmosphere. The proper use of this equipment minimizes the

loss of HFCs.

The 19XR PPS system shown in Fig. 1 consists of a pump-

out unit mounted on a storage tank. The pumpout unit is

offered as a free-standing unit that can be used with chillers

that have an existing storage tank or with chillers that have iso-

lation valves that permit built-in refrigerant storage.

The 19XR PPS systems are factory tested and certified to

the American Society of Mechanical Engineers (ASME) pres-

sure vessel code. The tanks are constructed of certified steel

and are pressure rated at 185 psig (1276 kPa). The PPS storage

tank is equipped with dual relief valves for proper venting per

ASHRAE 15 (American Society of Heating, Refrigerating, and

Air-Conditioning Engineers) guidelines. An automatic level

switch is prewired to the control circuit to ensure proper stor-

age levels.

The 19XR pumpout unit is a complete, hermetic, compact

unit that consists of:

• a hermetic reciprocating compressor with a direct-drive

motor.

• a water-cooled refrigerant condenser.

• an oil separator.

• suction and discharge valves to control refrigerant flow.

• prewired safety and control devices.

INSTALLATION

Step 1 — Complete Pre-Installation Checks

IDENTIFY UNIT — Identify the assembly number (see

Table 1) printed on the pumpout unit and storage tank name-

plates. Check this information against the job requirements.

Figure 1 shows the PPS system and its major components.

Refer to Tables 2 and 3 for physical data.

INSPECT SHIPMENT — Inspect unit for damage before

removing unit from shipping conveyance. If unit appears dam-

aged, it should be inspected by a shipping inspector before

removal. File a claim with the shipping company if shipment is

damaged or incomplete. The manufacturer is not responsible

for damage incurred during transit.

Check all components. Notify the supplier immediately if

any item is missing. To prevent loss or damage, leave all parts

in their original package until they are needed.

Step 2 — Mount the Pumpout Unit — The

pumpout unit, if purchased separately, may be mounted

directly on the chiller or it may be floor mounted.

MOUNTING ON THE CHILLER — See instructions pro-

vided with the chiller for mounting the pumpout unit. A typical

chiller mount is shown in Fig. 2.

FLOOR MOUNTING — Select a ventilated and accessible

area, free of traffic or other hazards. Remove and discard the

4 angle supports at the base of the pumpout unit and bolt the

unit to the floor through the holes at the base of the pumpout

unit. Special isolation is unnecessary. Contact surface and

dimensions for the pumpout unit are given in Fig. 3.

Table 3 — 19XR Storage Tank Rated Dry Weight and Refrigerant Capacity

LEGEND

*The above dry weight includes the pumpout unit weight of 164 lb

(75 kg).

Step 4 — Make Piping Connections — Figure 5

represents typical pumpout unit/chiller piping connections.

Standard connections for 1/2-in. OD copper tubing are provid-

ed. Install the field-supplied FPT tee with pipe plug in the pip-

ing as shown in Fig. 5. This tee is used for refrigerant charging.

NOTE: If any field piping runs exceed 50 ft in length, use

7/8-in. OD copper tubing to minimize pressure drop.

Pumpout unit water piping connections are shown in Fig. 5.

Both connections are 3/4-in. NPT (female). A shutoff valve

should be installed in the water line. Provide a means for blow-

ing water from the condenser coil at winter shutdown to

prevent freeze-up damage. Refer to the Job Data for water

piping particulars.

INSTALL VENT PIPING TO RELIEF DEVICES — The

pumpout storage tank is factory-equipped with relief devices.

Refer to Fig. 6 and Table 4 for size and location of the relief

devices. Vent the relief devices to the outdoors in accordance

with ANSI/ASHRAE 15 Safety Code (latest edition) for

Mechanical Refrigeration and all other applicable codes.

Pumpout unit relief devices are set to relieve at 235 psig

(1620 kPa). Storage tank relief devices are set to relieve at

185 psig (1276 kPa).

1. If relief devices are manifolded, the cross-sectional area

of the relief pipe must at least equal the sum of the areas

required for individual relief pipes.

2. Provide a pipe plug near outlet side of each relief device

for leak testing. Provide pipe fittings that allow vent pip-

ing to be disconnected periodically for inspection of valve

mechanism.

3. Piping to relief devices must not apply stress to the

device. Adequately support piping. A length of flexible

tubing or piping near the device is essential on spring-

isolated machines.

4. Cover the outdoor vent with a rain cap and place a con-

densation drain at the low point in the vent piping to pre-

vent water build-up on the atmospheric side of the relief

device.

Step 5 — Make Electrical Connections — See

nameplate on compressor of pumpout unit and Table 1 for

motor electrical data. Wire unit according to the diagram inside

the control box.

Figure 7 is the wiring schematic for a complete system that

includes the 19XR storage tank and the pumpout unit. Figure 8

is the wiring schematic for the pumpout unit. Use this schemat-

ic for installations that do not include an auxiliary pumpout

storage tank.

NOTE: Use copper conductors only.

NOTES:

1. The field-supplied tubing is to be 1/2-in. OD tubing (min.) and

must be arranged and supported to avoid stresses on the equip-

ment, transmission of vibrations, and interference with routine

access during the reading, adjusting, and servicing of the equip-

ment. If the distance from the chiller to the pumpout unit is over

50 ft, then 7/8-in. OD tubing (min.) must be used. Provisions

should be made for adjustment in each plane of the tubing and

for both periodic and major servicing of the equipment. Special

care must be taken so that the safety head does not experience

tubing strain. Vent the safety head per ASHRAE 15 (American

Society of Heating, Refrigerating, and Air-Conditioning Engi-

neers), latest revision.

2. The tubing and valve from the storage tank to the pumpout com-

pressor is factory supplied when the unit is factory mounted.
