would provide the occupant a warning if the primary drain is blocked.
K. AIR FILTER
Air handlers are factory equipped with an air filter. If the return grille has its own filter, the filter installed in the air handler should be removed. Air filter should be inspected and cleaned or replaced as often as is necessary to prevent restriction of air flow (minimum every three months for normal installations). Always replace the filter with the same type originally furnished.
L. CHECK TEST AND START UP
The unit should be tested after the system has been completely installed to determine proper operation. Energize the unit by switching on the line voltage source and the thermostat.
M. PERIODIC MAINTENANCE
Inspect and clean or replace filters at least every three months to ensure good airflow and optimum system capacity, efficiency and life. This equipment should NEVER BE RUN WITHOUT AN AIR FILTER in place (see Section AIR FILTER). The blower motor is permanently lubricated. ALWAYS disconnect power before removing access doors!
