Insufficient Cooling Or Heating; Failure To Operate; Lubrication Requirements; Periodic Maintenance - Bard MULTI-TEC W18AAPA Service Instructions Manual

50 and 60% Relative Humidity (RH) and typically affords acceptable human comfort conditions for most
individuals, and under no circumstances should be set lower than 40% as overcooling of the conditioned
space and/or freeze-ups of the indoor coil may occur.
In extremely hot or cold weather your system will continue to deliver its normal supply of conditioned air.
If the unit operates but fails to provide sufficient comfort, check the following before calling your Service
Company:
1. Be sure the thermostat setting is correct.
2. Check the air filters, and replace or clean if dirty.
3. Make sure that air can circulate freely throughout the conditioned space, and that all supply
registers and return air grilles are not blocked.
4. Make sure that the outdoor coil is not blocked with any foreign matter, or otherwise restricted with
any growth or other items.
Check the following before calling your Service Company:
1. Be sure the thermostat setting is correct.
2. Check the air filters, and replace or clean if dirty.
3. Make sure that the power supply, and gas or water supplies if applicable, are "On".
4. Make sure that air can circulate freely throughout the conditioned space, and that all supply
registers and return air grilles are not blocked.
5. Make sure that the outdoor coil is not blocked with any foreign matter, or otherwise restricted with
any growth or other items.
All indoor and outdoor air-moving motors are permanently lubricated, and require no re-oiling. If an
Energy Recovery Ventilator (ERV) is installed in your system, have your Service Company inspect
annually and perform maintenance as outlined in the ERV Installation and Operating Instructions.
Periodic maintenance must be conducted on your system to insure maximum performance, especially
during peak operating periods and conditions.
1. Keeping the air filters clean and recognizing the importance of a clean outdoor coil are key
elements. These are user responsibilities, either all or at least in part, and if they cannot be
fulfilled by the user, arrangements should be made with your Service Company.
2. There is a condensate drain system for all air conditioners and heat pumps, and this must be
kept open and free to convey the condensate generated by the operation of the equipment to a
suitable location, typically either an internal drain or outdoor location. Depending upon the
specific installation, the user would at least be aware of the dram mechanism and know what to
expect.
If any questions, it should be reviewed and discussed with your installer and/or Service
Company.
