Operating Instructions

For the 1564 Water Recirculation System

Purpose

The 1564 Water Recirculation System provides a convenient means to operate a Parr
6300 Calorimeter when a constant supply of good quality tap water is not available.
This unit works in conjunction with a water cooler such as the Parr 1552 to provide a
“closed loop” and therefore a well-controlled, enclosed system.

Safety Information
To avoid electrical shock, always:

1. Use a properly grounded electrical outlet of correct voltage and current handling
capability.

2. Ensure that the equipment is connected to electrical service according to local
national electrical codes. Failure to properly connect may create a fire or shock
hazard.

3. For continued protection against possible hazard, replace fuses with same type
and rating of fuse.

4. Disconnect from the power supply before maintenance or servicing.

To avoid personal injury:

1. Do not use in the presence of flammable or combustible materials; fire or
