The equipment room should be well ventilated and provided with adequate drainage capabilities so that should an emergency occur, resulting in flooding

from a pipe, filter or pump, the water can be easily removed to avoid property damage. If drainage cannot be supplied directly from the equipment room,

consideration should be given to the installation of alternate system to remove water from the mechanical room, per federal, state and local codes.

Filter Installation

When moving the filter(s) into place, not use the manway cover or opening to maneuver the filter. Be sure to use care if moving by hand. Before

continuing, be sure that the filter(s) are in the desired location with the connections facing the direction necessary for proper installation. It is also very

important to make sure that the filter is sitting on a level, hard surface.

It is possible that during transportation, some internal components have loosened. It will be necessary to remove the filter manway cover and enter the

filter, being careful not to break any of the connections. By hand, check the tightness of all the laterals in the bottom of the filter making sure they are

firmly tightened. By hand, check the tightness of all the distributors in the top of the filter making sure they are firmly tightened.

Note that HCF336C models include a 3" ANSI pipe flange (not shown) and requires the use of appropriate ABS to PVC adhesive.

Tank Positioning

Chalk lines are recommended for multiple tank installations and should be laid for positioning each tank. Attention must be paid to the location and rout-

ing of the influent, effluent and waste line plumbing when planning the proper location of the filter system. The tanks must be level and parallel to each

other or damage may occur to filter tanks, operating valves or connecting piping.

Installation of the Pressure Gauge

The pressure gauge assembly will come in a bag hanging from a diffuser within the filter. Remove all the parts from the bag and apply Teflon tape to all

threaded connections. Thread the pressure gauge (1) and bleeder valve (2) into manway cover (not shown). Once the system is started, open bleeder

valve (2) to bleed any air that might have been trapped in the filter during startup.
