7. MANUAL LOWERING DEVICE (MACHINE ROOM)
In the event of a power failure, the cab can be moved to a lower level manually
by using the following procedure:
1 Obtain the key to unlock the door to the machine room where the elevator
pump unit is located (if applicable).
2 Instruct the passenger (s) in the elevator to remain calm and stay well back
from the door of the elevator. Ease their concern by telling them your
intentions.
3 Switch the main disconnect switch for the main power supply to the
elevator pump unit to the "OFF" position.
4 If equipped, use the owner's key to
unlock the Controller Tank cover. The
EPV Valve is located inside.
5 Locate the RED manual release knob
on the EPV Valve and pull the knob to
lower the cab (refer to Figure 3).
Maintain a constant pull on the knob
until the elevator reaches the lowest
landing and stops automatically.
(Although you may not be able to see
the elevator, this is readily detected,
as there will be no further noise as
the oil flows to the reservoir).
6 To exit the cab, open the lower
landing door (using the special key)
and assist the passenger(s).
7 After the passenger has exited the
cab, remove the cab key. Make sure the landing door is closed, reconnect
the disconnect switch in the machine room, and lock the door.
