Liberty Pumps Pro370 Access Riser
Product Information
Product Name: Access Riser for PRO370 and PRO380 Series
Manufacturer: Liberty Pumps
Model Number: 7171000E
Website: www.LibertyPumps.com
The Access Riser is designed to be installed with the PRO370 or PRO380 simplex
ejector system. It allows for the system to be installed up to 18 inches below
ground level in an outdoor installation. The riser provides an underground
chamber for electrical and pipe connections to exit underground and out of
sight. It features a green twist-lock cover that can be removed to access
plumbing connections, valves, and the electrical junction box. Please note
that the Access Riser is not intended to increase the capacity of the basin
and should not be used as a gas or water-tight tank extension. For further
installation instructions and maintenance guidelines, please refer to the
separate Installation/Operation/Maintenance manuals provided with Liberty
Pumps products. If you have any questions or need assistance, you can contact
Liberty Pumps customer service at
1-800-543-2550.
Product Usage Instructions
- Before installation, ensure that you have received and read the separate Installation/Operation/Maintenance manuals provided with Liberty Pumps products.
- Ensure that you have all the necessary components for installation, including elbows, electrical fittings, and a junction box. These components may be included in the Access Riser kit or purchased separately.
- If you have purchased only the riser, you will need to purchase the 2 installation kit (IKIT2-115 or IKIT2-230) separately to complete the installation.
- If your system requires a 3 discharge system, some components may need to be mounted outside of the riser due to size constraints.
- Follow the typical installation diagram provided in the manual, which shows the PRO380 system with installation components from IKIT2-115/IKIT2-230. The AC18 cover is used to cover the riser, and the AR18 riser is installed underground.
- Use the provided junction box (JB120 or JB230) for electrical connections, depending on the voltage requirements of your system.
- Ensure that all installation and maintenance tasks are carried out by qualified personnel to reduce the risk of fire. 8. For further warranty information and to retain warranty coverage, retain the dated sales receipt.

The Access Riser allows a PRO370 or 380 simplex ejector system to be installed
up to 18 inches below grade in an outdoor installation. The riser provides a
convenient underground chamber for electrical and pipe connections to exit
underground and out-of-sight. A green twist-lock cover is removed to provide
access to plumbing connections, valves and the electrical junction box.
Important: The Access Riser is not a gas or water-tight tank extension to
increase the capacity of the basin.
IMPORTANT: All Liberty Pumps products are supplied with their own
separate Installation/Operation/Maintenance manuals. Ensure receipt of these
manuals, and that they are read and understood prior to installation. For
questions, call Liberty Pumps customer service at

- All installation and maintenance of pumps, controls, protection devices, and general wiring shall be done by qualified personnel.
Components and Available Kits
The riser is available by itself or as a kit with all the necessary components
for a professional installation including elbows, electrical fittings and a
junction box. If only the riser was originally purchased, the 2” install kit
will provide the necessary components to complete the installation.
Note: Due to size constraints, only 2” discharge installation kits are
available. 3” discharge systems may require that some components be mounted
outside of the riser.

Installation
The installation instructions that follow include those components included in the optionally available kits.
-
PRO370 or PRO380-Series sewage system installation Determine the overall height of the system and riser when excavating and setting the basin. The cover of the access riser should be at ground level when backfilling is complete. Burial depth of the system should not exceed 18” below finished grade. Determine the discharge, electrical, and vent positions relative to the system. The access riser slides over the PRO370/380 tank and can be rotated in any direction to simplify plumbing. The riser will rest on the concrete splash lip of the basin.
-
Sidewall pipe seal grommets installation
Once exit positions have been determined for both the vent and discharge, install a 2” pipe seal grommet by first drilling a 3” hole in the sidewall of the riser. The riser has four flat areas as well as a large ring that runs around the riser from which the discharge pipe or vent can exit. If both a check and ball valve are required, the discharge needs to exit on the opposite side (reference the Typical Installation Diagram). To ease installation of the pipe through the pipe seal grommet, grease the pipe or use liquid soap as a lubricant. -
Discharge connection
Thread a short pipe into the discharge port of the PRO-Series cover and attach a 90° elbow. A check valve is required to prevent water from backflowing and filling the basin, except in northern climates where frost may be a concern and pipes exiting from the side of the system may be exposed to freezing conditions. If this unit is installed in a frost zone, do not use a check valve. Substitute a union to facilitate cover removal and pump access. If a check valve is not used, the vertical lift should be minimized to reduce the amount of backflow after each cycle. A maximum length of 30’ of 2” pipe can be pitched to drain back into the system. Beyond 30’, discharge piping should be pitched down toward the final discharge destination. A ball valve is recommended so that backflow can be prevented in the event the pump or check valve must be removed for service. When connecting the check valve, ball valve, etc., carefully position items as close to the sidewall of the riser as possible to allow room for removal of the system cover. Use unions and couplings as necessary to allow for this. -
Vent connection
To maintain hidden pipes, the vent pipe can be routed underground to an existing household vent. For a 2” vent, a 3” hole should be drilled in the sidewall of the riser where the vent pipe is to exit. Install the pipe seal grommet. The pipe should be lubricated with liquid soap or grease to ease pipe installation. Thread a 90° elbow with male threads into the vent flange of the system. A rubber slip coupler should be installed in the vent piping to allow easy removal of the system cover and pump if service is required. -
Electrical connection
A NEMA 4X weatherproof pump station junction box (Liberty Pumps model JB120 or JB230) is recommended. It can be mounted inside or outside of the access riser. If mounting inside, reference the included Junction Box Template to drill the four mounting holes. If nonmetallic conduit is used, it must be mounted at least 18” below grade. Consult the National Electrical Code (NEC) and local codes for further information. Additional instructions are included with the JB120 or JB230 box. -
Backfilling
Use only fine, 1/8” to 3/4” pea gravel or 1/8” to 1/2” washed, crushed stone as backfill around the access riser. Do not use sand or native soil as backfill. Tamp backfill lightly. A light layer of topsoil can be used at cover level. Avoid running heavy equipment next to the riser. -
Cover installation
The cover features a twist-lock design and 4 stainless steel screws to secure it. When installing the cover, line up the four tabs with the four receptacles and locking tongue which fits into a cut recess in the underside of the cover. Push down and rotate the cover in a clockwise direction until the tongue bottoms in the slot. Install the four stainless steel bolts to secure the cover. A padlock can be placed through a hole in the tongue to deter unwanted entry. The cover is designed to handle light traffic loads such as walking or light lawn and garden equipment.
DO NOT RUN HEAVY TRACTORS OR OTHER EQUIPMENT OVER THE COVER. MAXIMUM LOAD RATING IS 250 LBS.
