WARNING
The hot gas line can become hot enough to cause injury in a very short time.
Do not allow prolonged contact during valve checkout.
On installations where the condensing unit is remote from the evaporator, it is
recommended that the hot gas bypass valve be mounted near the condensing unit to
minimize the amount of refrigerant that will condense in the hot gas line during periods
when hot gas bypass is not required.
