OMMISSIONING
4.1. Pre-commissioning inspection
Before commissioning the device, it is necessary to check the device and related installations. The basic control activities are
listed in the Pre-commissioning inspection protocol (appendix).
Check that the minimum distances are maintained for the correct operation of the device and that the necessary maintenance
space is available.
Find out if the device has been damaged or subsequently modified without the manufacturer's authorization, for example by
incorrect installation of cable trays or pipes (e.g. they may impede service access or air flow, etc.). There must be no screws
or other sharp objects near the condensers that could cause mechanical damage to the heat exchanger due to vibration.
It is recommended to obtain photo documentation from the installation site before putting the device into operation.
Before switching on the device for the first time or after a longer shutdown, the compressor oil must be warmed up.
The crankcase is heated by heating cables at least 12 hours before switching on. To start heating, turn the main switch
to the ON position. The crankcase heating function is automatically active when the main switch is in the (ON
4.2. Commissioning
The commissioning of the equipment may follow a previous inspection of the entire system (Pre-commissioning inspection)
in a situation where the subsequent cooled (heated) heated system can be loaded to at least 60% of the equipment output.
In the case of reversible coolers, it is possible to put the device into operation in both modes during the transitional period,
otherwise the commissioning process must be completed under suitable conditions.
A detailed description of operating sequences, modes, parameters and alarm messages is given in the ACS Control System
Manual. It can be used during commissioning:
Variable speed fan and pump test modes
Possibility of manual shutdown of selected compressors during commissioning
Temporary setting of the desired water temperatures for accelerating / decelerating the operating sequence
Temporarily switch off the flow control before starting the device (e.g. during external pump control)
Commissioning protocol
The commissioning report should contain information on the operating parameters at the first start-up, identification of the
equipment, name and confirmation of the qualified service and confirmation of the commissioning customer - a sample is
given in the appendix.
The completed Commissioning Protocol is a condition of warranty performance in the event of a device complaint.
Operator training
The operator of the cooling system must be trained during commissioning, ie before the formal commissioning, which begins
with the signing of the Commissioning Protocol (Annex).
As part of the operator training, the future operator will get acquainted mainly with:
•
Safety rules for operating cooling equipment
•
Basic tasks of user operation and weekly inspections (chapter maintenance)
•
Basic operating sequence
•
Temperature and pressure safety elements
•
Basics of wiring and safety elements
•
Operation of the control unit and setting of basic parameters
•
Alarm states and possibilities of their solution
•
Documentation for cooling equipment - Operating instructions for the equipment and control system, Wiring
diagram
•
Obligation to keep operational documentation and protocols (appendix)
