GAS SUPPLY VALVE HAS BEEN TURNED OFF.
To guarantee trouble-free operation of this unit, the manufacturer suggests following these guidelines.

of this manual.
General Maintenance
• Fan inlet and approaches to ventilator and coils should be kept clean and free from any obstruction.
Clean both the indoor and outdoor coils regularly to maintain unit efficiency.
• Motors are normally permanently lubricated. Check bearings periodically. If they have grease fittings,
lubricate each season. Use caution when lubricating bearings, wipe the fittings clean, the unit should
be rotated by hand while lubricating.
Caution: Use care when touching the exterior of an operating
motor. Motors normally run hot and may be hot enough to be painful or cause injury.
• All fasteners should be checked for tightness each time maintenance checks are performed prior to
restarting unit.
• Fans require very little attention when moving clean air. Occasionally oil and dust may accumulate
causing imbalance. If the fan is installed in a corrosive or dirty atmosphere, periodically inspect and
clean the wheel, inlet, and other moving parts to ensure smooth and safe operation.
• The Energy Wheel will require very little attention when moving clean air. Occasionally oil and dust
may accumulate, degrading performance. If the ERV is installed in a dirty atmosphere, periodically
inspect and clean the wheel, belt, and other moving parts to ensure smooth and safe operation.
• Before each heating season, verify that the drain on the bottom of each common flue box of every
furnace in the unit is clear.
Every 3 months
Filters need to be cleaned and/or replaced quarterly, and more often in severe conditions. Washable
filters, located in the intake louver or ERV module, can be washed in warm soapy water. When re-installing
filters, be sure to install with the same size and rated filter and with
airflow in the correct direction
as
indicated on the filter.
