Open Centrifugal Refrigeration Machines

Centrifugal liquid chillers are designed to provide safe
and reliable service when operated within design speci
fications. When operating this equipment, use good
judgment and safety precautions to avoid damage to
equipment and property or injury to personnel.

Be sure you understand and follow the procedures and

safety precautions contained in the machine instructions

as well as those listed in this guide.

A DANGER

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
literature and the design pressures on the equipment

nameplate.
DO NOT VALVE OFF any safety device.
BE SURE that all pressure relief devices are properly

installed and functioning before operating any machine.

A WARNING

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
circuits are de-energized before resuming work.

DO NOT syphon refrigerant by mouth.
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

refrigerant cylinder. Dangerous overpressure can result.
When necessary to heat refrigerant, use only warm
(110 F/43 C) water.

DO NOT REUSE disposable (nonreturnable) cylinders
nor attempt to refill them. It is DANGEROUS AND
ILLEGAL. When cylinder is emptied, bleed off remain
ing gas pressure, loosen the collar and unscrew and

discard the valve stem. DO NOT INCINERATE.

CHECK THE REFRIGERANT TYPE before charging

machine. High pressure refrigerant in a low pressure
machine can cause vessels to rupture if the relief devices
cannot handle the refrigerant volume.

DO NOT ATTEMPT TO REMOVE fittings, covers, etc.

A SAFETY GUIDE

while machine is under pressure or while machine is
running. Be sure pressure is at zero psig before breaking
any refrigerant connection.

CAREFULLY INSPECT all relief valves, 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 valve when corrosion or 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. The accumulation of refriger

ant in an enclosed space can displace oxygen and cause
asphyxiation.

DO NOT install relief valves in series or backwards.
USE CARE when working near or in line with a.

compressed spring. Sudden release of the spring can
cause it and objects in its path to act as projectiles.

A CAUTION

DO NOT STEP on refrigerant lines. Broken lines can
whip about and cause personal injury.

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 compo
nents. Even if components are light, use such equipment
when there is a risk of slipping or losing your balance.

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

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.

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
that 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.

INTRODUCTION

General — All persons concerned with the start-up

and operation of the centrifugal refrigeration
machine should be familiar with the equipment
involved. This instruction book is intended to
cover general rules for start-up procedures.

Because of machine variations it is not possible
to prepare an instruction book covering all minor
details. This instruction book will fulfill normal
requirements. Additional information may be ob
tained by application to Carrier Machinery and
Systems Division Service Supervisor in the nearest
district office.

Special attention should be given to precaution
ary instructions emphasized in this book to avoid
start-up difficulties. These precautions are, in
general, applicable to all sizes of 17DA centrifugal
refrigeration machines.

Instructions for the prime mover if not in

cluded with Carrier Air Conditioning instructions
should be obtained from the manufacturer.

MOTOR DRIVE — Disconnect the main motor
leads at the starter to check out the safety controls
without operating the motor. Disconnecting the
leads to the starter holding coil will accomplish the
same purpose. Place a volt-ohmmeter across the
open leads. The volt-ohmmeter will indicate when
the safety control circuit is de-energized as each
safety control is tripped.

TURBINE OR GAS ENGINE DRIVE - These
drives are shut down by interruption of power to
their respective control valves or other devices.
Apply a volt-ohmmeter across these open leads and

check out all safety controls as just described.

LEAK TEST AND DEHYDRATION

Check the absolute pressure on the refrigerant

side of the machine. The final operation of the

17DA Installation Instruction is to leak test the
machine and dehydrate it to the point where it
maintains a pressure of 0.21 psia (equivalent to

29.48 in. mercury vacuum referenced to a 30 in.
barometer). Refer to Carrier Standard Service Tech
niques, Form SM-1.

If the machine absolute pressure is higher than
the above values, repeat the Evacuation and De
hydration pumpdown operations until the machine

proves to have a leak rate or vacuum loss at a rate
less than 0.1 in. mercury column in 24 hr.

CHARGE MACHINE WITH WATER

When the machine has been proved leak tight

and dry, it may be filled with water, brine or other
process fluid as the case may be. Vent aU lines and

check for leaks.

It is advisable to install indicators on the

coupling halves between the compressor and drive

or gear to check for alignment drift while charging
with water and refrigerant. The weight of these
materials will always cause a shift in the position of
the machine components. Before and after indi

cator readings will give a good clue to the direction

final alignment should take.

CHARGE MACHINE WITH OIL

The 17DA machine has an integral lubrication
system mounted on the common base with the
compressor. A parallel auxiliary oil pump system

may also be furnished. Charge the oil system with

35 gal. of oil per Carrier Specification PP16-0
(Table 4). If oil other than this is used, the

replacement oil must be nearly equivalent.

Ensure that there is adequate lubrication prior
to the operation of all equipment. Check the gear
and drive manufacturer’s instructions for proper
initial lubrication procedure. If the drive
machinery is to be operated before operating the

compressor, disconnect the shaft coupling and'
secure the shroud to prevent damage to the drive
shaft or the coupling.

Oil pressure from the main oil pump is set at a

pressure 35 psi greater than the back-of-seal oil
pressure. If, for any reason, the oil pressure falls to
23 psi above the back-of-seal oil pressure, the
auxiliary oil pump starts and maintains oil pressure
at a safe level.

Prior to operating the compressor and speed
increasing gear (if used), coupling alignment and
separation must be checked.

1. Ensure that coupling alignment is within
coupling manufacturer’s specified tolerances.

2. The hub separation tolerances are normally

stamped on coupling and vary depending on
coupling size.

3. When checking hub separation, electric motor
shaft must be in center position of shaft float.

If realignment is required, follow instructions

supplied by coupling manufacturer. Carrier Standard
Service Techniques, Form SM-15, Rev A, also de
tails realignment techniques.

OPERATE DRIVE

It is good practice to operate the drive sep
arately before operating compressor. Refer to drive
manufacturer’s instructions for drive protection
devices and settings. Check turbine overspeed at
this time. Reassemble couplings after operating
drive separately.

SET PURGE VALVES AND SWITCHES

Open all the purge service valves behind purge

console. Place purge operating valves in NORMAL­AUTOMATIC position (shown on chart inside
console door). Place purge switch in AUTO,
position.

CHECK WATER SUPPLY

Be certain that chilled water, condensing water
and oil cooler water supplies are available and that
pumps will run before operating compressor.

CHECK AIR SUPPLY, PNEUMATIC MACHINES

Make sure that control air is 35 psig.

START-UP

Preoperation Settings — Complete these settings

before starting compressor for first time.

Drive Operation — Refer to drive manufacturer’s

start-up instructions. Complete drive starting

requirements before operating compressor.

If drive is wired for automatic starting, it will
start when compressor START button is pushed.
Starting procedure of manually started drives may

be initiated after START button is pushed.

Compressor Operation

1. Place control switch in ON position. Con
denser pressure, bearing temperature and
refrigerant temperature indicating lights on
control console should come on.

2. Place capacity control switch in MANUAL
position.

3. Open oil cooler water plug cock. Check fqr
water flow at open sight drain.

4. Open bleed valve on inboard side of the

compressor.

5. Open all valves and energize heater on seal oil
drain pot.

6. Open all valves in chilled water and condenser
water circuits.

WARNING: No brine over lOOF must be
allowed to flow thru the cooler.

7. Ensure that there is water in the cooling tower.

8. If the auxiliary equipment such as chilled
water pump, condenser water pump, and

cooling tower fan are not wired into control
console circuit, start these items manually

before starting the compressor.

9. Start oil pump.

10. Close bleed valve on inboard side of the
compressor.

11.17DA compressors are equipped with an
AUTO-MANUAL control station. The initial
start should be on manual control from this
station.

12. Start compressor.
a. Bump electric motors by pushing the

START and STOP buttons in quick
succession. Compressor rotation must be
counterclockwise when viewed from drive
end.

b. Run turbine or engine drives at slow

speed.

13. Listen carefully for unusual mechanical noise
while coasting down.

14. Shut down.

Charge Refrigerant

WARNING: When liquid Refrigerant-12 is in
jected into a low vacuum of 29.48 in. mercury

it will unmediately flash to a gas at a tempera
ture lower than minus 100 F. It is for this
reason that water must be circulating before

charging liquid refrigerant. Non circulating
water would quickly freeze and damage the
machine. If an auxiUaiy' refrigerant storage tank

(receiver) is furnished, liquid refrigerant may be

charged directly into this evacuated receiver

without danger.

Large machines run with liquid refrigerant in

the cooler so refrigerant is charged into the cooler

or low-pressure side of the machine. For general

instructions on how to handle refrigerant refer to

Carrier Standard Service Techniques, Form SM-1.
Use the Charging by Weight method, cross check
ing with the machine’s refrigerant sight glass pro
vided on the back of the cooler shell, and the

suction pressure gage.

Charge refrigerant as follows:

1. Start Cooler and Condenser water circulating
pumps.

2. Charge the first refrigerant in the vapor state,
continuing until the machine pressure exceeds
35 psig. The refrigerant temperature corre
sponding to this pressure is high enough to

prevent water freezing damage and will also
satisfy the refrigerant low-pressure cutout
safety switch setting (31.5 psig). Now turn the
refrigerant bottles or drums over and begin
charging the refrigerant in the liquid phase.
Continue charging liquid refrigerant until about
2/3 of the estimated full load charge is in the
machine.

3. Adjust control station to operate at MANUAL.
Ensure that the guide vanes are closed as
indicated on the main guide vane indicator.

4. Set Subcooler Level Controller as follows:

a. Set Proportional Band at 35%.
b. Set Level-Set adjustment at 50%.
When stable operation is achieved, readjust

Level-Set to maintain the Hquid level at the

midpoint of the sight glass on the Level

Controller. Recheck this level when full load is

reached and reset if necessary.

5. Start the compressor. Observe the machine’s
operation for 15-20 min before increasing the

load. During this period, make the following

checks and adjustments :
a. Check oil pressure.
b. Adjust water flow thru oü cooler so that

bearing temperatures stay between 150 F
and 170 F approximately.

c. Watch bearing temperatures carefully. This

is the first time that the machine has been
run under refrigeration load. Bearing tem
peratures may level off at some temperature

slightly higher than 170 F hsted above. This
may be the normal stable condition for this
bearing. High thrust bearing temperature
will shut the machine down at 180 F.

6. Slowly open the guide vanes, by manual con
trol, thus increasing the load. Do not exceed
the current rating of the electric motor. Watch
for other signs of overloading a turbine or
engine drive.

7. Add Uquid refrigerant, trimming the charge off
at the point where the machine reaches design
operating temperature and pressure conditions.

WARNING: Excessive overcharge may cause
liquid refrigerant carry-over into the com
pressor, causing severe overload and possible
compressor damage.

8. Shut the machine off. When the refrigerant
level settles down, mark this optimum level on
the sight glass. Maintain this shutdown level. To
determine the approximate refrigerant charge
for your machine, add the cooler charge to the
applicable condenser charge as listed in Table 5.

After the machine has been running at about

full load for four hours, its components will have

come up to steady state operating temperature
conditions and the final hot alignment check may

be made.

Realign component locations until angular and
parallel alignments are within coupling manu
facturer’s specified tolerances.

Dowel all equipment into place as soon as the
hot alignment check proves that the machine is
within these running tolerances.

See Carrier Standard Service Techniques, Form

SM-15, Rev A, for these operations.
