CAUTION: Risk of excessive refrigerant line pressure. Can cause equipment damage or injury resulting from
tubing and component rupture. Do not close off the refrigerant-line isolation valve for repairs unless a
pressure-relief valve is field- installed in the line between the isolation valve and the check valve. The
pressure-relief valve must be rated 5% to 10% higher than the system-design pressure. An increase in
ambient temperature can cause the pressure of the isolated refrigerant to rise and exceed the system-design
pressure rating (marked on the unit nameplate).
