Final Inspection & Start-up Checklist ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ Inspect and ensure that all components and accessories have been installed properly and that they have not been damaged during the installation progress. Check the condensate water drain(s) to ensure that they are adequate for the removal of condensate water, and that they meet the approval of the end user. Ensure that all installation instructions concerning clearances around the unit have been adhered to.
Routine Maintenance Service and Assistance To ensure proper unit operation, the air filter should be cleaned at least monthly, and more frequently if conditions warrant. The unit must be turned off before the filter is cleaned. Before calling for service, please check the “Troubleshooting Tips” section on Pages 46 and 47. This may help you to find the answer to your problem, avoid unnecessary service calls, and save you the cost of a service call if the problem is not due to the product itself.
