Hello.  We here in Ontario, Canada have very strict laws for us
restorers concerning the safety of all items operated by electricity,
and this includes antique music makers.  All electrical appliances must
have a "Ontario Hydro Sticker" to show it has met their standards.

When we do a Pianomation installation we have to have an inspector visit
the shops, inspect the job and put the stamp of approval on our
"Identification plate", which shows our name, serial # of instrument,
Voltage, Amps & Hz.  Failure to do so will result in a fine and other
untold problems for the future.

In a nutshell all coin acceptors must be low voltage (less than 18
volts).  All wiring must be 3 wire. (+,- & ground) everything must be
grounded in metal boxes.  All components used must be CSA or UL
approved.

We always install a fuse in the hot lead to the vacuum motors. This will
blow if the motor gets overheated because of air not going through it.
Its part number is 7AM025A3-188 and it is available from most Shopvac or
vacuum cleaner motor repair shops.  We also always have them, the cost
is about .00.  So if we are restoring, say, a Seeburg K for use in
Ontario, we have to install a 3-prong plug and the correct size wire
cord with strain reliever, and ensure that everything is grounded
including the piano plate.  Use low voltage on the coin mechanism, which
means everything old and original can stay as is, and the low voltage
flips a relay to operate the motor.  The transformer for the low voltage
and relay, on/off switches, etc., are housed in metal boxes.  If the
customer does not want this done we have him sign a letter stating so.

Safety First.  Especially when doing restoration for others.

For what its worth,

Ron Schmuck
