Outdoor Unit Installation
*1. Pipe length vs. vacuum pump run time.
*2. If the compound pressure gauge pointer swings back, refrigerant may have water content or a loose pipe joint may exists.
Check all pipe joints and retighten nuts as needed, then repeat steps 2) through 4).
6.
Refilling the refrigerant
Check the type of refrigerant to be used on the machine nameplate.
Fill from the gas pipe in liquid form.
NOTE
National implementation of EU regulation on certain fluorinated greenhouse gases may require to provide the appropriate official
national language on the unit. Therefore an additional multilingual fluorinated greenhouse gases label is supplied with the unit.
Sticking instructions are illustrated on the backside of that label.
6) Turn the liquid stop valve’s rod 90 degrees counterclockwise with a hexagonal wrench to open valve.
Close it after 5 seconds, and check for gas leakage.
Using soapy water, check for gas leakage from indoor unit’s flare and outdoor unit’s flare and valve rods.
After the check is complete, wipe all soapy water off.
7) Disconnect charging hose from gas stop valve’s service port, then fully open liquid and gas stop valves.
(Do not attempt to turn valve rod beyond its stop.)
8) Tighten valve caps and service port caps for the liquid and gas stop valves with a torque wrench at the specified torques.
