Original Instructions (English)
Preventative Maintenance
WARNING
Use extreme care to avoid burns if removing and replacing heaters while the platen is
above room temperature. Wear proper heat protective gear suitable for SPF press
operation before attempting to remove or replace MULTICELL heaters while the press
is at operating or idle temperatures. In some cases the platen holes may warp and
distort over time, and the heater might be easier to remove while the platen is at or
near operating temperature.
WARNING
The User must ensure that the installer uses all relevant PPE (Personal Protection
Equipment).
WARNING
– Risk of Electric Shock
If an enclosure is provided, the terminal enclosure cover is bonded to enclosure body
to ensure an effective ground fault current path. If this bonding conductor is
disconnected for any reason it must be reconnected for safety. The typical
connection utilizes two external tooth lockwashers to sandwich the conductor ring
terminal against the connection base and the tightening nut/screw. All hardware must
be replaced. Retighten connections to 2.3 N·m (20 in-lb).
WARNING
– Risk of Electric Shock
High voltage is present when the heater is energized and hence preventative
maintenance of this heater shall only be done by qualified personnel.
Turn all power off to
the heater and “Lock Out / Tag Out” the power disconnect
switch(es) for the heater before performing any preventative maintenance.
It is the U
ser’s responsibility to ensure that proper precautions are taken in reference
to applicable personal protective equipment needed by those installing and
maintaining equipment.
