GENERAL NOTES
1. WARNING-For continued protection against fire hazard replace fuses with the same type and rating only.
2. Unit must be permanently grounded and conform to N.E.C. & local codes.
3. Use copper conductors for field-wiring. Class 1, unless noted. All wire based on 105°C insulation wire, minimum.
4. Wire colors shown may differ from actual unit.
5. Drawing line item reference identification:
- Number in parenthesis near output is location of controlled items.
- First number is sheet #, second & third are line#
- No underline indicates normally open (NO) contact
- Underline indicates normally closed (NC) contact
6. Design, specifications, and components are subject to change without notice.
7. All intellectual property, including designs and programming logic are the property of Cold Shot Chillers and is not

* PAGE NOTES
1. Control transformers must be wired/tapped for the appropriate incoming voltage. Depending on design, one dual
voltage or two independent voltages.
2. Models -24 to -90 models have 1 fan, -120 and -150 models have 2 fans. -180 and -240 models have 3 fans.
3. Fan speed controller will be installed on #2 fan on 120 to 150 models and installed on #3 on 180 and 240 models.
4. Fuse block, contactor, and overload may be used in place of motor starter and contactor combination.
5. Single phase pump motors may be used. Motors must be internally, thermally protected.
