GREE GMV5 HR HEAT RECOVERY UNITS
306
Specific procedure is as follows:
(1) GMV5 series units use FVC68D lubricant. Make sure to confirm the trademark of the lubricant
first. Lubricant of other trademarks is not allowed.
(2) Open all valves and extract air for 30 minutes or longer.
(3) Connect a rubber hose to the oil checking valve at one end. Open the container that holds
lubricant and pour lubricant into a measuring glass. If the glass is too small to hold the lubricant
of a required amount, measure the lubricant portion by portion. Record volume of each portion
and then put the other end of the rubber hose into the glass.
(4) Keep on extracting air and open the oil checking valve. The lubricant will be pressed into the
low pressure side of units.
(5) If the lubricant is added portion by portion, close the oil checking valve first and then measure
another portion of lubricant. In the course of repeated measuring and adding, keep the
extraction action.
(6) After a required amount of lubricant is added, close the oil checking valve to ensure tightness.
Note: Lubricant is of great importance to the normal running of compressors. You should follow
Gree’s requirement to add qualified lubricant of the specified trademark and ensure properness of fill
