Maintenance & Troubleshooting
Maintenance and Trouble Shooting
Maintenance for the BULLDOG system is simple and easily done. Essentially it consists of establishing regular inspection and filter changes. To remove the filter from the unit lift the filter up and pull it out of the unit at the bottom. Replace the old filter by sliding the top edge of a new filter up into the rack, then pushing in the bottom of the filter until it drops into place. For complete maintenance instructions consult the Installation and Operations Manual for the SpaceKeeper Horizontal Products.
Always remember to disable the unit using the disconnect before servicing to prevent injury or death due to electrical shock or contact with moving parts.
