NOTES:

1.FACTORY SUPPLIED AS SHOWN BY CONNECTION TO OUTPUT OF CONTROL TRANSFORMER T1. WIRE NUMBER

100& 121.

2.ALTERNATIVELY THE SUPPLY MAY BE TAKEN FROM AN

INDEPENDENT SOURCE: IN THAT CASE, FACTORY SUPPLIED CONNECTION MUST BE DISCONNECTED.

3. ENSURE PARALLEL CONNECTION OF HEATERS.

NOTES:

1.CONNECTIONS FOR USE ON 200/230V SYSTEMS. THE SUPPLY IS INDEPENDENT OF THE MAIN COMPRESSOR. THE CUSTOMER MUST PROVIDE AN ISOLATOR / DISCONNECT SWITCH ADJACENT TO THE MACHINE FOR THIS SUPPLY. IN THAT CASE, FACTORY SUPPLIED CONNECTION MUST BE DISCONNECTED.

2.ENSURE SERIES CONNECTION OF HEATERS.
