Power Cord; Check Valve - Liberty Pumps 404 Manuel D'installation

INLET: The pump has two available ports: one on the top, the other on the side. Either can be used as a vent or inlet. Using the
appropriate piping (1-1/2" on the model 404 and 2" on models 405, 405HV) connect the fixture to the pump. Note: a trap shall be used
between the fixture and pump, a flange type is recommended. HAND-TIGHTEN TO PUMP. DO NOT OVERTIGHTEN OR CROSS-
THREAD.
A. DISCHARGE: HAND-TIGHTEN ONLY. Install a union just above the pump to facilitate removal if necessary for cleaning or
service. Install a check valve just above the union (as close to the pump as possible) to prevent the backflow of water after each
pump cycle.
B. VENT: Provision is made for a vent stack to allow extra volume for high suds conditions, and to ensure proper drainage of the
fixture. HAND-TIGHTEN ONLY. DO NOT CAP-OFF VENT. DO NOT use ONE-WAY QUICK-VENTS or AIR ADMITTENCE
VALVES as they will not guarantee proper fixture performance. The vent pipe should have a union to facilitate removal if required
and shall be connected directly to a building or house vent.
C. POWER CORD: The pump power cord is equipped with a grounding conductor and grounding-type 3-prong plug. It should be
connected to a separately fused, grounded, 3-wire grounding-type receptacle of 15-amp capacity with the proper voltage for your
model. Make sure all electrical wiring and connections are in accordance with the National Electric Code and all applicable local
codes.
MODEL 404 (including CV, /A, /A-EYE) - 115 volts
MODEL 405 (including /A, /A-EYE) - 115 volts
MODEL 405HV - 230 volts

Risk of electric shock. Always disconnect the pump from
the power source before handling or making adjustments.

DO NOT remove the plug or ground prong.

DO NOT use an extension cord.
D. CHECK VALVE: 404/CV, 404CV/A, and 404CV/A-EYE come with a check valve in order to meet ASME112.3.4 / CSAB45.9. This
check valve must be threaded into the discharge port of the 404 cover. HAND-TIGHTEN ONLY, WITH APPROPRIATE THREAD
SEALANT OR TEFLON TAPE. DO NOT CROSS THREAD.
E. ALARM: 404s and 405s with /A or /A-EYE come with a Liberty alarm. For instructions on using this alarm, please read the included
alarm manual.
The 404 and 405-series pumps come factory-equipped with a float switch mounted within the tank. These models come with two
cords - one to the float switch and the other to the pump motor. The switch cord has a series (piggyback) plug enabling the pump cord
to be plugged into the back of it (see Fig. 4). The purpose of this design is to allow temporary manual operation of the pump.
For automatic operation using Liberty's supplied switch, the two cords should be interconnected and plugged into a separately fused,
grounded outlet of proper amp capacity for your selected pump model. (See the pump's nameplate for electrical specifications of your
model.) Both cords are equipped with 3-prong plugs and must be plugged into a properly grounded 3-wire receptacle. DO NOT
REMOVE THE GROUND PRONGS.
