1. GENERAL USER AND MAINTENANCE MANUAL
1.1 HOW TO USE THIS MANUAL
This operating and maintenance manual is intended for specialist personnel who are responsible for the
installation, commissioning and operation of cooling water recirculating chillers of the type CHW, oil recir-
culating chillers of the type CHO and glycol recirculating chillers of the type CHG. The term “chiller” is
used as a general name for these appliances.
This operating and maintenance manual is an essential constituent of the chiller. Every user, operator
and service technician is required to carefully read the information and instructions contained in this op-
erating and maintenance manual – particularly those that affect safety – before transporting, installing,
using, performing any maintenance on or disposing of the chiller.
The owners and operators of the chiller shall ensure that all work to be carried out on the chiller is only
undertaken by personnel with suitable specialist qualifications.
The operating and maintenance manual is divided into two sections that contain a detailed description of
the three type series CHW, CHO and CHG, with their respective standards and with additional information
on the customer-specific design and the respective model of your chiller, wherever this differs from the
standard model. Here you will find information such as the circuit diagram for the chiller you have cho-
sen.
1.2 GENERAL DESCRIPTIONS/INTENDED USE
The CHW, CHO and CHG chillers have been designed for the purpose of keeping a certain quantity of
cooling medium, e.g. water, water-glycol moisture or oil constantly within certain temperature limits (op-
erating range), with the aid of a technical cooling process. The most commonly used cooling medium,
also called the “consumer refrigerant” is mains water. This operating manual uses the general term cool-
ing medium. However, the cooling medium and the materials used in the circuit must be compatible with
one another. It is therefore necessary to check and ensure before commissioning that the cooling me-
dium is suitable for the intended purpose.
These chillers are recommended for use in the recirculated chilling of liquids (cooling media) in industrial
and commercial applications, particularly in cases where specific and constant temperatures are required,
such as in mechanical engineering, in the plastics industry, in surface technology and in the laser indus-
try.
Explanation of the product designations CHW, CHO and CHG:
CHW recirculating water chiller
