ASL Pre Winter Check List

Main Store

All sales floor sensors to be checked against reading from Trend and actual reading at Sensor

Ensure all sensors on the sales floor are in place to be checked with BMS

The sensor should be located in an area representative of the entire control zone. This applies to additional sensors from other optimisers etc

Pendant sensors should be 600mm long located away from direct air flow patterns from diffusers.

Sensor is installed at a height of 1.5m in occupied spaces and at least 50 cm from any adjacent walls.

The sensor should be located in an area representative of the entire control zone. This applies to additional sensors from other optimizers etc

The sensor should be located away from heat sources e.g. TV walls

Ensure Outside temperature sensor is located in a North facing position and not exposed to direct solar radiation. Outside temperature sensors to be checked against reading from Trend and actual reading at Sensor

Final Heating / pressurisation checks. Force heating on and check

Check Heater banks operating

Check All pumps running

Check Package units operating

Check All fans are operating correctly and fan belts are correctly fitted

Check All VSDs operating at 100% design speed when on demand and dropping to 80% when set point reached

Check that the supply air cuts out at design temp (This will not mean that it has the capacity as the outside air temperature will be higher than the winter, it will just show that it can hit the high limit)

Check all filters on air handling units to ensure maximum air flow can be achieved.

Check operation of cold aisle heating

Check operation of cold air retrieval

Check operation of front door air curtains

Check and measure air velocities from outlets on the sales area and balance accordingly ideal velocity 2-3 m second.

Measure the temperature in the cold aisle is it achieving design (16.5oC along middle of the aisle at 1.5metres)

Is the store achieving pressurisation ( this can be tested out of hours by closing all doors onto the sales floor and opening the front doors by 300mm and ensuring all AHUs are running at 100%) the velocity through the gap should be in excess of 1.5m/s

Check Freshair air dampers go to minimum outside air inorder to maintain store pressurisation.
