current for standard models is listed in Table 5.
2. Install a service disconnect switch in plain sight of the filter and not more than
50ft (15m) away.
3. Install an externally operated manual or magnetic starter with thermal
overload and fuse protection. If the unit is to be controlled remotely with a
time clock, switch, or other device, a magnetic starter must be used. The
thermal overload protection (if required) must be sized for the full load amp
draw listed on the pump motor nameplate.
Single and Three Phase Automatic Units
Install a separate power supply line with circuit breaker protection between the
closest branch distribution panel and the control box. The full load current for
standard single and three phase units is listed in Tables 4 & 5. The control box
contents are pre-wired and include a service disconnect switch, thermal
overload/short circuit protection, and a transformer to convert the power supply to
single phase 110 VAC for controls (for pump motor voltages other than 110 VAC).
Wire the power supply lines to the disconnect switch. All incoming power supply
lines must connect to the door interlock disconnect.
Loading Filter Media
The specially manufactured spherical silica sand media used in PEP media filters is
designed to remove suspended solids 10 micron and larger, typically up to 90% by
volume. Optional media is available to remove up to 90% by volume of suspended
solids down to 5 and 0.5 micron and larger. The media will ship to the job site in ½
cubic ft. drums (50 lbs/23 kg) or 1 cubic ft. bags (100 lbs/46 kg) for easy handling
during the media loading process.
The garnet media is packaged in ½ cu.ft. containers and weighs approximately 70
lbs/32kg.
Actual quantities may vary slightly with vessel pressure ratings. Correct quantities
will be noted on the shipping and inspection records for each system.
The fill gravel must be loaded into the filter tank before the silica sand media.
Never load gravel into a dry filter vessel. Fill the vessel one-third full with
water before loading. Always check integrity of filter internals before loading
media.
