Final Tubing Check

IMPORTANT:

Check to be certain factory tubing on both indoor and 
outdoor unit has not shifted during shipment. Ensure 
tubes are not rubbing against each other or any sheet 
metal. Pay close attention to feeder rubes, making sure 
wire ties on feeder tubes are secure and tight.

Open service valves

Open or close the valve.

Liquid and gas side

Open the valve with a  

4 mm

 hexagon wrench.

• While the valve is fully opened, after the screwdriver 

has reached the stopper, do not apply torque 
exceeding 4 ft•lbs (5 N•m). Applying excessive 
torque may damage the valve.

Valve handling precautions

• Open the valve stem until it reaches the stop.

It is unnecessary to apply further force.

• Securely tighten the cap with a torque wrench.
• Cap tightening torque
