FACILITY OPERATIONS AND MAINTENANCE RECOMMENDATIONS

❑ HVAC unit components (filters, coils etc.) can be contaminated. Take necessary precautions while servicing equipment.

❑

While working on roof, keep distance from sewer vent pipes where possible.

❑

Replace filters more frequently.

❑

Run restroom exhaust continuously 24/7. Increase restroom exhaust rates if exhaust and make up system capacity allows.

❑ Ensure CO2 sensors are working properly for monitoring (all zone and system level). ❑ If UVGI systems are applied, control human exposure. In duct / AHU systems should be provided with dedicated disconnects to service.

❑ Ensure UVGI compatible sealants and filtration system is utilized.
