7.0 Start-Up and Commissioning   

 

Ensure that a Return Air Filter is fitted prior to fan start up  

 

Measure and record the system details as noted under PRELIMINARY SYSTEM INFORMATION and check all 

items as noted under PRE START-UP on the Commissioning Sheet provided 

 

Switch the unit on in cooling mode with the thermostat set to minimum temperature set point 

 

Measure and record all items as noted under OPERATION CHARACTERISTICS on the Commissioning Sheet 

provided 

 

Check suction and liquid pressures 

 

Care must be taken to charge the system correctly. Undercharge will result in lack of capacity and the unit may 

lock out on its LP (Low Pressure) safety switch. Overcharge will result in high head pressures whilst unit is 

operating 

 

Measure the compressor suction pressure and convert to a compressor saturated suction temperature (CSST) 

using R410a refrigerant pressure/temperature table 

 

Measure the suction line temperature (SLT) approximately 100mm before the compressor 

 

Calculate the superheat (SH) = SLT – CSST 

 

Measure the compressor discharge pressure and convert to a condensing temperature (CT) using R410a 

refrigerant pressure / temperature table 

 

Measure the liquid line temperature (LLT) between the outdoor coil and indoor unit throttling device in cooling 

mode 

 

Calculate the sub-cooling (SC) = CT – LLT 

 

Measure the outdoor ambient air temperature 

 

Measure the indoor return and supply air dry bulb temperatures, both before and after the indoor coil 

 

Measure the indoor air quantity ensuring it falls within the Indoor Coil’s limits  

 

Adjust the fan speed to suit the static pressure and air quantity requirements 

 

Allow system pressure to stabilise for a minimum of 20 minutes 

 

Instruct the customer on system capability and correct operation 

 

Please ask the customer to fill in the CUSTOMER DETAILS section and to register their product warranty with 

Brivis
