Apartment Circuit Balancing
It is vital that both the DHW circuits and heating circuits are fully balanced as per the
specification and design parameters. This should be carried out and completed prior to
commissioning work has been carried out.
We would again highlight that our technical personnel, who will visit the project
during the course of the installation and at its completion to arrange for its final
commissioning and calibration, do so to assist the contractor and install team to
deal with any questions and queries. They do not perform the role of quality control or
inspector of the installation or provide approval for the works carried out. The systems
compliance with the consultant’s requirements and current standards and legislation
remains the exclusive responsibility of the installer / M&E contractor and comments
provided by Evinox are for guidance / advice only.
Once the initial commissioning checks have satisfactorily been carried out and checking
the operation of both the heating and hot water functions. The unit will then require full
commissioning by an Evinox engineer. During the commissioning procedure the unit will
be fully set up to the system design parameters. All commissioning must be booked well in
advance and will be carried out to a pre-agreed programme.
The items checked during commissioning, whilst not exhaustive, will include the following:
Hydraulic
connections
Electrical
connections
Primary flow rate and temperature
Secondary flow rate and temperature
Pump PWM settings
DHW draw-off rate and outlet temperature
Setting of unit parameters and unit functions
Meter
reading
Check of domestic hot water blending valve operation
Check operation of all safety devices
Once all of the following has been carried out a certificate will be issued:
All commissioning has been carried out satisfactorily.
The unit is installed to Evinox’s requirements.
The unit is operating within design parameters.
