Introduction - Carrier AquaEdge 19XR Series Start-Up, Operation And Maintenance Instructions Manual

WARNING
DO NOT USE eyebolts or eyebolt holes to rig chiller 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 con-
trol 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 servicing.
IF WORK IS INTERRUPTED, confirm that all circuits 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 liquid refrigerant 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 it is neces-
sary to heat refrigerant, use only warm (110°F [43°C]) water.
DO NOT REUSE disposable (nonreturnable) cylinders or at-
tempt to refill them. It is DANGEROUS AND ILLEGAL.
When cylinder is emptied, evacuate remaining gas pressure,
loosen the collar. and unscrew and discard the valve stem. DO
NOT INCINERATE.
CHECK THE REFRIGERANT TYPE before adding refriger-
ant to the chiller. The introduction of the wrong refrigerant can
cause damage or malfunction to this chiller.
Operation of this equipment with refrigerants other than those
cited herein should comply with ANSI/ASHRAE 15 (latest
edition). Contact Carrier for further information on use of this
chiller with other refrigerants.
DO NOT ATTEMPT TO REMOVE fittings, covers, etc.,
while chiller is under pressure or while chiller is running. Be
sure pressure is at 0 psig (0 kPa) before breaking any refriger-
ant connection.
CAREFULLY INSPECT all relief valves, rupture discs, and
other relief devices AT LEAST ONCE A YEAR. If chiller op-
erates 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 mecha-
nism. Replace the device.
DO NOT install relief devices 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.
CAUTION
Failure to follow these procedures may result in personal inju-
ry or damage to equipment.
DO NOT STEP on refrigerant lines. Broken lines can whip
about and release refrigerant, causing personal injury.
DO NOT climb over a chiller. Use platform, catwalk, or stag-
ing. 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 mechanical equipment when there is
a risk of slipping or losing your balance.
BE AWARE that certain automatic start arrangements CAN
ENGAGE THE STARTER, TOWER FAN, OR PUMPS.
Open the disconnect ahead of the starter, tower fans, or pumps.
USE only repair or replacement parts that meet the code re-
quirements of the original equipment.
DO NOT VENT OR DRAIN waterboxes containing industrial
brines, liquid, gases, or semisolids without the permission of
your process control group.
DO NOT LOOSEN waterbox cover bolts until the waterbox
has been completely drained.
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.
DO NOT re-use compressor oil or any oil that has been ex-
posed 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 prevent oil con-
tamination when timely repairs cannot be completed.

INTRODUCTION

Prior to initial start-up of the 19XR unit, those involved in the
start-up, operation, and maintenance should be thoroughly famil-
iar with these instructions and other necessary job data. Proce-
dures in this manual are arranged in the sequence required for
proper chiller start-up and operation. This book also outlines the
control system for those involved in the start-up, operation, and
maintenance of the unit before performing start-up procedures. It
is intended to be used in combination with the 19XR Controls Op-
eration and Troubleshooting manual that describes PIC 6 controls
in detail.
UNIT DAMAGE HAZARD
This unit uses a microprocessor-based electronic control sys-
tem. Do not use jumpers or other tools to short out compo-
nents or to bypass or otherwise depart from recommended pro-
cedures. Any short-to-ground of the control board or accompa-
nying wiring may destroy the electronic modules or electrical
components.
Do NOT punch holes or drill into the top surface of the starter
enclosure for field wiring. Knockouts are provided for field
wiring connections.
PROVIDE MACHINE PROTECTION. Store machine and
starter indoors, protected from construction dirt and moisture
and if required follow Carrier Long Term Storage guidelines.
Inspect under shipping tarps, bags, or crates to be sure water
has not collected during transit. Keep protective shipping cov-
ers in place until machine is ready for installation.
