INTRODUCTION
The Metronic 5200 BF is an electrolytic recovery system
intended to recover silver from fixer and bleach fix. This is
a closed loop recirculating recovery system that continu-
ously passes the spent fixer and bleach fix solution from the
10 gallon desilvering tank through the plating chamber. The
silver is deposited on a cathode inside the electrolytic
chamber. The unit turns on automatically when the 10 gallon
desilvering tank reaches the 3.5 gallon level.
The unit will run in the recirculating mode until the
maximum amount of silver has been recovered.
At the end of the recirculating cycle, which varies with
silver concentration, the unit will go into a drain mode until
all the chemistry is out of the holding tank and plating
chamber. It will then automatically turn off and wait for the
next batch of chemistry.

Electrolytic Chamber (SPU) (See Fig. B)
This chamber is equipped with one (1) round 5" anode,
one (1) 8" cathode, one(1) circulation pump, and one(1)
discharge pump.
Rectifier (EMP) (See Fig. H)
The rectifier is equipped with digital current readout, level
control, and power switch.
Desilvering Tank (See Fig. F)
The desivlering tank is a 10 gallon holding tank with High/
Low level controls set to start at about 3.5 gallons.

SAFETY PRECAUTIONS
BEORE STARTING PUMP
Read operating instructions and instructions supplied
with chemicals to be used.
Refer to Chemical Resistance Data Chart for compati-
bility of materials in pump with solutions to be used.
Note temperature and pressure limitations.
Personnel operating pump should always wear suitable
protective clothing: face mask or goggles, apron and
gloves.
All piping must be supported and aligned independently
of the pump.
Always close valves slowly to avoid hydraulic shock.
Ensure that all fittings and connections are properly
tightened.
