Tips & Tricks

Follow these 3 simple steps when selecting, preparing and installing GREE and you’re well on your way to success…

Select the right GREE equipment.

  1. Review Sales Brochures on GreeComfort.com to determine which system(s) are the right fit for your customer and their application.
  2. Review Gree Reference Guide on GreeComfort.com for a quick cross reference and comparison between the different Gree models.
  3. Review Submittals on GreeComfort.com to determine the equipment capacity, operating range, efficiency, refrigerant line sizes & min/max lengths, electrical data/power supply requirements as well as all Indoor/Outdoor Unit installation clearance requirements.

Before you install GREE equipment: 

  1. Ensure that you have the tools required such as a R-410a Flaring Tool, Torque Wrench, Nitrogen Regulator that will go up to 500-600psi, vacuum pump, micron gauge, digital refrigerant scale that measures in ounces, 1/4” x 5/16” adapter to connect refrigerant gauge/hose, and all other HVAC tools and safety equipment needed to successfully complete the installation & start up.
  2. Ensure that you have all material needed such as refrigerant line set (with lines insulated separately), nitrogen, additional refrigerant (if needed), condensate drain line (condensate pump if needed), interconnecting cable, condenser pad, service disconnect (fused type recommended), correct size circuit breaker, liquidtite AC whip, line set cover, etc. to complete the installation with only making 1 trip to the jobsite.
  3. Review all Installation Training Videos on GreeComfort.com (and Gree ToolBox) and contact your local distributor with any questions to minimize installation issues and downtime on the jobsite.

Installation

  1. Review the installation manual at the jobsite BEFORE installing the equipment to confirm all factory installation requirements such as clearances, refrigerant line lengths, electrical requirements, etc. are adhered to, and also double check that all material provided is correct and matches what is listed in the installation manual for the max breaker size, refrigerant line sizes, etc.
  2. Ensure the installation meets all local, state, and federal codes.
  3. Once a successful startup has been completed, document the refrigerant pressures, indoor supply/return and outdoor ambient temperature, supply voltage to Outdoor and Indoor Units, amperage of Outdoor Unit, compressor, condenser fan, and Indoor Unit, additional amount of refrigerant added, take pictures of all data plates, and register the installation on GreeComfort.com/register to earn your PERK Points for $$$!
