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.
