9 CommissioningInstaller reference guide67EBLQ+EDLQ011~016CA3V3+W1 + EK(2)CB07CAV3Daikin Altherma low temperature monobloc4P538847-1 – 2018.059 Commissioning9.1 Overview: CommissioningThis chapter describes what you have to do and know tocommission the system after it is configured.Typical workflowCommissioning typically consists of the following stages:1 Checking the "Checklist before commissioning".2 Performing an air purge.3 Performing a test run for the system.4 If necessary, performing a test run for one or more actuators.5 If necessary, performing an underfloor heating screed dryout.9.2 Precautions when commissioningINFORMATIONDuring the first running period of the unit, the requiredpower may be higher than stated on the nameplate of theunit. This phenomenon is caused by the compressor, thatneeds a continuous run time of 50 hours before reachingsmooth operation and stable power consumption.NOTICENEVER operate the unit without thermistors and/orpressure sensors/switches. Burning of the compressormight result.9.3 Checklist before commissioningAfter the installation of the unit, first check the following items. Onceall below checks are fulfilled, the unit MUST be closed, ONLY thencan the unit be powered up.Depending on the system layout, not all components may beavailable.You read the complete installation instructions, asdescribed in the installer reference guide.The outdoor unit is properly mounted.The control box is properly mounted.The option box is properly mounted.The following field wiring has been carried out accordingto the available documentation and the applicablelegislation:▪ Between the local supply panel and the outdoor unit▪ Between the outdoor unit and the control box▪ Between the control box and the option box▪ Between the local supply panel and the control box▪ Between the local supply panel and the option box▪ Between the outdoor unit and the valves▪ Between the control box and the room thermostat▪ Between the control box and the domestic hot watertankThe system is properly earthed and the earth terminalsare tightened.The fuses or locally installed protection devices areinstalled according to this document, and have NOT beenbypassed.The power supply voltage matches the voltage on theidentification label of the unit.There are NO loose connections or damaged electricalcomponents in the switch box.There are NO damaged components or squeezedpipes on the inside of the outdoor unit.Backup heater circuit breaker F1B (field supply) isturned ON.Only for tanks with built-in booster heater:Booster heater circuit breaker F2B (on the switch box ofthe control box) is turned ON.The correct pipe size is installed and the pipes areproperly insulated.There are no water leaks inside the outdoor unit.The shut-off valves are properly installed and fully open.The pressure relief valve purges water when opened.The minimum water volume is guaranteed in allconditions. See "To check the water volume" in"6.3 Preparing water piping" on page 23.If glycol was added to the system, confirm the correctglycol concentration, and check if glycol setting [E‑0D]=1.NOTICE▪ Make sure glycol setting [E-0D] matches the liquidinside the water circuit (0=water only, 1=water+glycol).If the glycol setting is NOT set correctly, the liquidinside the piping can freeze.▪ When glycol is added to the system, but the glycolconcentration is lower than prescribed, the liquid insidethe piping can still freeze.INFORMATIONThe software is equipped with an "installer-on-site" mode([4‑0E]), that disables automatic operation by the unit. Atfirst installation, setting [4‑0E] is by default set to "1",meaning automatic operation is disabled. All protectivefunctions are then disabled. If the user interface homepages are off, the unit will NOT operate automatically. Toenable automatic operation and the protective functions,set [4‑0E] to "0".36 hours after the first power-on, the unit will automaticallyset [4‑0E] to "0", ending "installer-on-site" mode andenabling the protective functions. If – after firstinstallation – the installer returns to the site, the installerhas to set [4‑0E] to "1" manually.9.4 Checklist during commissioningThe minimum flow rate is guaranteed in all conditions.See "To check the water volume and flow rate" in"6.3 Preparing water piping" on page 23.To perform an air purge.To perform a test run.To perform an actuator test run.Underfloor screed dryout functionThe underfloor screed dryout function is started (ifnecessary). |
