INSTALLATION
1. Mounting: Locate the feeder so there is
direct access to the power cord plug.
: DO NOT POSITION SO THAT
COOLING VENTS IN THE REAR OF THE
CASE ARE OBSTRUCTED, .19in. (4.7mm)
minimum ventilation clearance is required, see
Figure 1.
2. Alternate Mounting (not approved for ‘CE’): Set
the feeder on a flat level surface that will support its
weight. The feeder should be mounted on its 4(four)
rubber feet (or use keyholes on back for wall mounting
(4.75in. (12.07cm) typical spacing), see Figure 1.
Locate the feeder so there is direct access to the
power cord plug.
3. Electrical - Verify the electrical requirements for the pump as
listed on the pump data label and connect to an appropriate electrical
source in compliance with local codes for the specific application.
4. Injection Fitting - Relieve system pressure in the drain piping run where the injection fitting is to be
installed. See Figure 2. The injection fitting must not be installed in a dead end pipe or a deeply
recessed tee. It should be installed so as to place the tip at the center of the fluid stream.
The
injection fitting has .25-18 NPT (female) threads. If necessary drill a .44in.-diameter hole and using care not
to tap to deeply, tap for .25-18 NPT. Apply Teflon tape to the injection fitting threads and install into piping
system. DO NOT REMOVE THE PLASTIC SLEEVE ON THE TIP OF THE FITTING. It is a functional part.
: Inspect piping system and eliminate piping cross-connections to prevent feeding
chemical to areas not needing treatment.
