Routine Maintenance

Side Load Filters

Most filters in custom units are installed in unitary sheet metal frames. If unit is provided with side

access rack, do the following for installation:

2-inch or 4-inch flat filters

1. Disconnect the power to the unit.

2. Open the filter section access door and remove the filters and block-offs from their installed

position.

3. Slide the filter into the rack.

4. Some side load racks will be provided with block-off plates. Install them into the rack last before

closing the door.

5. Close and secure the door, making certain the door closes snug against the block-off.

Cartridge or Bag Filters

To replace cartridge or bag filters:

1. Disconnect all electrical power to the unit.

2. Remove the dirty filters and block-offs from their installed position.

3. Keeping the new bag filters folded, slide each filter into the filter rack, pushing them tightly

against the unit.

Note: The pleats on bag filters should be in the vertical position.

4. If using the optional pre-filters, replace them on the appropriate filter rack.

5. If fixed and adjustable block-offs are provided with the unit, slide the fixed block-offs into the

filter track before the adjustable block-off.

Note: The adjustable block-off should always be installed last, next to the access door.

6. Close and secure the access door. If the door can be closed without compressing the filter,

adjust the block-off by loosening its screws and position it to provide an airtight seal.

Drain Pans

 WARNING

Hazardous Chemicals!

Cleaning agents can be either acidic or highly alkaline. Handle chemical carefully. Proper

handling should include goggles or face shield, chemical resistant gloves, boots, apron or suit as

required. For personal safety refer to the cleaning agent manufacturer’s Materials Safety Data

Sheet and follow all recommended safe handling practices. Failure to follow all safety

instructions could result in death or serious injury.

 WARNING

No Step Surface!

Do not walk on the sheet metal drain pan. Walking on the drain pan could cause the supporting

metal to collapse. Failure of the drain pan could result in death or serious injury.

The condensate drain pan and drain line must be checked to ensure the condensate drains as

designed. This inspection should occur a minimum of every six months or more often as dictated

by operating experience.

If evidence of standing water or condensate overflow exists, identify and remedy the cause

immediately. Refer to “Troubleshooting” on page 98 for possible causes and solutions.
