REPLACING THE DRYER FILTERS

Replace the filters when the machine alerts you. Replace the filters only with
Mastercool part numbers: 69788-FLTRPK. When changing the filters you will need
a filter code. To obtain a filter code, please call Mastercool Inc. Technical Service at
888-825-6989.
LOCK OUT: If you are changing the filters because of the Second Service alarm (see
page 10) and has locked out 69789/69789-H, then a filter code will be needed to
re-set 69789/69789-H. Before changing the filters, call Mastercool Inc. Technical
Service at 888-825-6989 to get the filter code.
NO LOCK OUT: If the filters are being changed at an unscheduled time, no filter
code will be needed to continue operating 69789/69789-H. Only when the machine
reaches the pre-programmed recovery quantity of 132 lbs will it lock out. Once the
machine is locked out, the filter code will be needed to re-set the 69789/69789-H.
