MOUNTING & SET-UP INSTRUCTIONS FOR GAST LOA-P109-AA COMPRESSOR UNIT
Prior to using the system, some assembly and adjustments are required. Please locate these parts and ensure all items are present. These items are required to
mount and set-up the GAST LOA-P109-AA Compressor assembly as well as to connect the tubing to the GAST LOA-P109-AA Compressor and aeration tank.
• GAST LOA-P109-AA Compressor/Bracket Assembly
• RETROFIT KIT
• 1/4” Polyethylene Tubing (10 feet)
• A4FE4-MG (1/4” NPT x 1/4” Quick Connect Elbow)
IMPORTANT NOTE
This product includes a GAST® component. Refer to the GAST’s website @ www.gastmfg.com for their instruction and operation manual for detailed
instructions and safety information related to Model # LOA-P109-AA Oil-less Compressor.
How It Works:
When the GAST LOA-P109-AA Compressor is running, it injects air into the water which causes iron to precipitate. The precipitated iron is then fi ltered as it
passes through the APPM Iron Reduction Filtration System. There are two ways to turn the GAST LOA-P109-AA Compressor on.
1. For Private Water Well Systems — The GAST LOA-P109-AA Compressor can be wired to either a pressure switch in the water well system or a fl ow switch
installed in the service side of the iron reduction fi ltration system. The GAST LOA-P109-AA Compressor is activated on a standard well pump system by
a pressure switch that senses pressure in the water line. When the preset low pressure side of the switch is met, the GAST LOA-P109-AA Compressor is
turned on and will continue to run until the high pressure setting is reached, at which time the GAST LOA-P109-AA Compressor is turned off. On a fl ow
switch application the GAST LOA-P109-AA Compressor is wired into the fl ow switch and is energized when water fl ows through the fl ow switch and turns
on the GAST LOA-P109-AA Compressor. The GAST LOA-P109-AA Compressor will continue to run until water fl ow in no longer detected.
2. For Split Stream or Public Water Supply – An FS1 Flow Switch (sold separately) is installed in the service line and turns on the GAST LOA-P109-AA
Compressor when water fl ow exceeds 0.5 gpm. See Page 3-1 for installation diagram.
GAST LOA-P109-AA Compressor Mounting Instructions:
1. Locate the GAST LOA-P109-AA Compressor/Bracket Assembly within six (6) feet of the aeration tank.
2. Thread A4FE4-MG onto the brass check valve located on the compressor. The
quick connect end of the elbow should already be plugged with a Plug00007.
Keep the plug installed to set the air release fi tting. Fitting should point to the
fl oor as shown in Figure 2.
3. The mounting bracket should be mounted on a surface that will support vi-
bration, preferably to studs or a concrete wall. The installer must choose and
supply the appropriate fastener for mounting the bracket to the wall.
4. When using the FS1 Flow Switch, the power supply must be connected to a
dedicated 110 VAC, minimum
15 amps, 60 Hz. Power supply. Follow NEC and/
or all relevant codes for your area.
5. If the system is being serviced, insert the Plug00007 plug found in the RET-
ROFIT KIT into the quick connect fi tting on top of the air release tank head
to set the air release fi tting. This is the only component of the RETROFIT KIT
you will use.
Wiring Instructions:
WARNING
To reduce the risk associated with hazardous voltage:
• Disconnect line circuit power before wiring the switch and compressor. Consult a licensed electrician for correct and safe connection of the fl ow
switch and GAST LOA-P109-AA Compressor to the home electrical system.
1. For Well Systems – The GAST LOA-P109-AA Compressor can be wired to run in parallel to the well pump pressure switch. The air compressor runs on
110 VAC and has a standard 3 wire connection (black, white, and green wires). The leads of the GAST LOA-P109-AA Compressor must be made on the
well pump motor contacts. All contacts must be made in accordance with NEC and local codes and standards. Use a licensed electrician to perform this
task to ensure safety and correctness.
2. For Use With A Flow Switch – An FS1 Flow Switch should be installed in the service line after all water treatment equipment (e.g. APPM Iron Reduction
Filtration System, etc.). The FS1 plumbing connection is 1” PVC socket (solvent weld) and must be installed horizontally and the top in an upright position
or it will not function correctly. Make sure the direction of water fl ow matches the
arrows on the FS1 Flow Switch. .
The FS1 comes with a power cord installed, but the GAST LOA-P109-AA Compressor power cord must be connected to the fl ow switch in order to operate.
The GAST LOA-P109-AA Compressor must be wired to run when water fl ow is detected in the treated water line. The electrical leads must be fed through
the strain relief on the fl ow switch and attached to the wire leads provided on the micro switch under the cover of the fl ow switch. Follow the instructions
provided by the manufacturer of the fl ow switch. The fl ow switched power cord must be plugged into a 110 volt, 60 hertz circuit with a minimum 15 amp
rating on a non-switched electrical outlet. A licensed electrician must perform the wiring needs for this application to ensure the electrical connections
are made in accordance with the NEC and local codes and standards.
