SAFETY CONSIDERATIONS

Installing, starting up, and servicing air-conditioning equip-

ment can be hazardous due to system pressures, electrical com-

ponents, and equipment location.

Only trained, qualified installers and service technicians

should install, start up, and service this equipment.

When working on air-conditioning equipment, observe pre-

cautions in the literature and on tags, stickers, and labels at-

tached to the equipment.

Follow all safety codes. Wear safety glasses and work

gloves. Use care in handling equipment.

INTRODUCTION

These instructions cover field installation of the accessory hot

gas bypass (HGBP) valve and solenoid pilot valve on specific

models. These models include the 30GT Flotronic™ chillers

and 30GN Flotronic II chillers in sizes 040-420. Also included

are all 30GTN,GTR,GUN,GUR040-420, 30GTN015-035 and

30HK,HL040-060 ComfortLink chillers. See Table 1.

On Flotronic chillers (30GT) with either no unloaders or

2 unloaders, the accessory hot gas bypass must be added to

both circuits because of an automatic lead-lag feature. On

ComfortLink chillers (30GTN,GTR,GUN,GUR040-070 sizes),

the addition of a compressor unloader solenoid coil must also be

added to compressor B1 to use the configurable lead-lag feature.

On 30GN,GT,GTN,GTR,GUN,GUR130-210 sizes, 2 hot

gas bypass packages must be installed, one on each circuit. On

30GN,GT,GTN,GTR,GUN,GUR230-420 sizes, 4 hot gas by-

pass packages must be installed, 2 on each unit module (Mod-

ules A and B).

For 30GT units, hot gas bypass will be activated only if the

lead compressor on a circuit is active. For 30GN,

30GTN,GTR, 30GUN,GUR and 30HK,HL units, hot gas by-

pass will be activated only if the lead compressor on a circuit is

both active and unloaded.

NOTE: The lead compressor in circuit A is compressor A1.

The lead compressor in circuit B is compressor B1. For loca-

tion of lead compressor, refer to component arrangement in

wiring schematic on unit.

Table 1 — Accessory Application

Be sure power to equipment is shut off before performing

maintenance or service.

IMPORTANT: When removing refrigerant, use an

approved refrigerant recovery device. Do not vent refrig-

erant into the atmosphere.

IMPORTANT: The following 2 combinations ARE NOT

ALLOWED on 30GN,GT,GTN,GTR,GUN,GUR230-

420 units.

• Two unloaders and hot gas bypass on one circuit.

• Four compressors, 1 unloader, and hot gas bypass

on one circuit.
