Troubleshooting Guide

Additional gas charging

(Gas leakage)

•When refrigerant is insufficient by leakage, recharge the unit with the refrigerant up to normal oper- ating suction pressure.

•Use the graph or the equation below to get operating suction pressure according to indoor and out- door temperature.

Suction pressure was measured at 3-way valve service port after operating the unit for 10 minutes.

The method of using graph

-Find outdoor temperature.

-Find indoor temperature onto the curve of outdoor temperature.

-Read suction pressure at the axis of ordinates.

The method of using equation

-. Calculate suction pressure after putting indoor and outdoor temperature into the equation.
