Electrical shock can cause personal injury and death. Shut

off all power to this equipment during installation and ser-

vice. There may be more than one disconnect switch. Tag

all disconnect locations to alert others not to restore power

until work is completed.

This unit uses a microprocessor-based electronic control

system. Do not use jumpers or other tools to short out com-

ponents, or to bypass or otherwise depart from recom-

mended procedures. Any short-to-ground of the control

board or accompanying wiring may destroy the electronic

modules or electrical components.

To prevent potential damage to heat exchanger tubes

always run fluid through heat exchangers when adding or

removing refrigerant charge. Use appropriate brine solu-

tions in cooler and condenser fluid loops to prevent the

freezing of heat exchangers when the equipment is exposed

to temperatures below 32 F (0 C).

DO NOT VENT refrigerant relief valves within a building.

Outlet from relief valves must be vented outdoors in accor-

dance with the latest edition of ANSI/ASHRAE (American

National Standards Institute/American Society of Heating,

Refrigeration and Air Conditioning Engineers) 15 (Safety

Code for Mechanical Refrigeration). The accumulation of

refrigerant in an enclosed space can displace oxygen and

cause asphyxiation. Provide adequate ventilation in enclosed

or low overhead areas. Inhalation of high concentrations of

vapor is harmful 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 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.

Failure to follow these procedures may result in personal

injury or death.

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 prevent oil contamination when timely

repairs cannot be completed. Failure to follow these proce-

dures may result in damage to equipment.

CONTENTS (cont) ComfortLink Compressor Protection (CCP) Board — The CCP board monitors the high-pressure Page switch status, running current and motor temperature for each compressor. Each CCP board controls up to 2 compressors. The CCP board also controls the motor cooling solenoid, oil solenoid and contactor outputs. A pre-punched configuration header for each compressor determines the must trip amps setting.

Back Pressure Valve (30GXN,R and 30HXA only) — This valve is located on the oil separator outlet on 30GXN,R units and mounted on the oil separator shell of 30HXA units. The valve’s function is to ensure that there is sufficient system differential pressure to allow for oil to be driven back to the compressor.

INPUTS: • motor temperature • three-phase current • high-pressure switch A diagram of the CCP board is shown in Fig. 4. One CCP board is installed on 30GXN,R080-178 and 30HXA,C076-186 units and two CCP boards are installed on 30GXN,R204-350 and 30HXA,C206-271 units. The address for each CCP board is set using DIP (dual in-line package) switches. For CCP1 (compressor A1 and B1), DIP switch 1 should be set to ‘L’ (‘On’ position for LEN communication). Switches 2, 3 and 4 should be set to ‘0’ (“OFF” position).

Position 12 in model number) are supplied with factoryinstalled Wye-Delta starters. All other voltage options can be ordered with either Wye-Delta or XL starting options. The XL starting method is the most cost effective and simply starts the compressor motor in a Delta configuration (the motors are designed for continuous operation in this configuration) using a single contactor. See Fig. 5. This is the simplest starting method to use and is ideal where starting current does not require limiting.

When there is chilled water flow, but the flow is inadequate to close the switch and allow unit operation, one red LED will illuminate. A red LED can also indicate inoperative pump(s), closed valve, clogged strainer or air in the system. When the first green LED is illuminated, the switch is closed and the unit will start and run. Various conditions can cause variations in flow and allow the switch to open and cause a “nuisance trip”. Greater constant flow will help reduce nuisance tips.

BRAZED-PLATE ECONOMIZERS — Brazed-plate economizers are factory-installed in each circuit on 30GXN,R108, 118-350 and 30HXA,C161-271 models. A TXV is included to meter the flow of refrigerant to the economizer port of the compressor. Flow through the TXV is enabled only when the circuit is fully loaded for 30GXN,R models. The TXV bulb is secured to the side of the economizer outlet tube. See Fig. 22 for typical piping arrangement. Brazed-plate heat exchangers cannot be repaired if they develop a leak.
PAGE 52
SERVICE Servicing Coolers and Condensers — When cool- er heads and partition plates are removed, tube sheets are exposed showing the ends of tubes. The 30GXN,GXR,HX units use a flooded cooler design. Water flows inside the tubes. TUBE PLUGGING — A leaky tube in one circuit can be plugged until retubing can be done. The number of tubes plugged determines how soon the cooler must be retubed. All tubes in the 30GXN,R and 30HX coolers and 30HX condensers can be removed.

7. Thoroughly rinse all surfaces with low velocity clean water using downward rinsing motion of water spray nozzle. Protect fins from damage from the spray nozzle. Remove Surface Loaded Fibers — Surface loaded fibers or dirt should be removed with a vacuum cleaner. If a vacuum cleaner is not available, a soft brush may be used. In either case, the tool should be applied in the direction of the fins. Coil surfaces can be easily damaged (fin edges bent over) if the tool is applied across the fins.

2. At these operating conditions, check the liquid line sight glass. If there is a clear sight glass, then the unit has sufficient charge. If the sight glass is flashing, then check the EXV Percent Open. If this is greater than 60%, then begin adding charge. NOTE: A flashing liquid line sight glass at operating conditions other than those mentioned above is not necessarily an indication of low refrigerant charge. 3. Add 5 lb (2.

TEMPERATURE MEASUREMENT (CIRCUIT B) Addition of oil charge to 30HX,GXN,GXR systems: 1. If the 30HX,GXN,GXR unit shuts off repeatedly on Low Oil Level (Alert number 124 or 125), this may be an indication of inadequate oil charge. It could also mean simply that oil is in the process of being reclaimed from the low-side of the system. 2. Begin by running the unit at full load for 11/2 hours. Use the Manual Control feature of the software if the unit does not normally run at full load. 3.

shutoff valve (if equipped) for circuit to be changed. Disconnect the oil inlet line from the compressor. Disconnect oil filter with fitting at shutoff valve side and set filter and compressor inlet line assembly aside. 3. Remove any remaining refrigerant in the compressor and refrigerant lines using proper reclaiming techniques. All of the refrigerant that is in the cooler must be removed if there is no suction service valve installed on the cooler. 11. If low oil level problems persist, add another 1.

13. After checking to ensure all lines, wires, conduits, etc. are free and out of the way, remove compressor from cooler. Apply a light film of O-ring grease to new O-ring and place back into groove in mounting flange of compressor. If the new compressor is the A1/A2 (30HX units), A2 (30GXN,R204-268 units) or B2 (30GXN,R281-350 units) compressor, remove the compressor junction box and rotate it 180 degrees. Tighten screws to 6.8 to 9.5 N-m (5 to 7 ft-lb).

HPS Moisture-Liquid Indicator — Clear flow of liquid refrigerant indicates sufficient charge in the system. Note, however, that bubbles in the sight glass do not necessarily indicate insufficient charge. Moisture in the system is measured in parts per million (ppm), changes of color of indicator are: Green — moisture is below 80 ppm; Yellow-green (chartreuse) — 80 to 225 ppm (caution); Yellow (wet) — above 225 ppm. Change filter drier at the first sign of moisture in the system.

To Service Compressor Motor Thermistors — Two thermistors are factory installed in each compressor. Connections for the thermistors are located in the compressor junction box. There are 3 terminals for the thermistors: S1, S2, and C. Motor temperature is measured by leads connected to one of the S terminals and the C terminal. If a compressor motor thermistor failure occurs, verify that there is a true short or open circuit at these ter- minals.

Upon building pressure, the compressor is allowed to start (after 15 seconds). For across-the-line (XL) start chillers, the compressor starts and comes up to full speed within 1 to 3 seconds. For Wye-Delta start chillers, contactors 1M and S (starter contactor assembly) are closed and the compressor is started in a Wye configuration. This method reduces the locked rotor current requirements by approximately 60% while maintaining enough torque to bring the compressor up to full speed.
