INTRODUCTION

These instructions cover field installation of the Acces- sory Hot Gas B y ass Valve and solenoid pilot valve on the following chi Plers:

30HK,HL015 through 060 (50 and 60 Hz) 30GB040,045,055,070 (60 Hz), Flotronic’”

30GB040,046,050,055,070 (50 Hz), Flotronic’” 30GB075 through 200 (50 and 60 Hz), Flotronic’” 30GTOl5,025,030,035 (60 Hz)

30GT020,025,030 (50 Hz)

On Flotronic chillers with no unloaders or 2 unloaders, the accessory hot gas bypass must be added to both circuits because of ati automatic lead-lag feature.
