Typical Grinder Pumping System Installation

  (8)   Secure power cord to avoid entanglement with variable level 

float switch mechanism.

  (9)  

Do not

 reduce pump discharge pipe below 2” (51mm) IPS size.

 (10)   Basin 

must 

be in accordance with all applicable codes

 

  and specifications. Basin must be sized to allow a minimum  

3 minute off-time between starts.

  (11)   Pump must be level and the tethered variable level float switches 

must be free and not hang up on pump or pit peculiarities.

 (12) 

If

 a rail system is used, discharge elbow 

must

 be firmly an-

chored to the bottom of basin. In fiberglass basin, the bottom 

will need to be reinforced if the discharge elbow is used.

 (13) 

If

 a rail system is used, the guide rails are 2” (51mm) schedule 

40 pipe for all units. Brass, stainless steel or galvanized steel 

is recommended.

 (14)   Install ring and cable for lifting pump from pit.
 (15)   Basin must be clean and free of debris after installation and 

before operation.

 

ZEPA0521

All installations must comply with all applicable 

electrical and plumbing codes, including, but 

not limited to, governing electrical code, local, 

regional, and/or state plumbing codes, etc.

  (1)   Electrical wiring and protection 

must 

be in accordance with the 

governing electrical code, and any other applicable state and 

local electrical requirements.

  (2)   Install proper full flow check and shut-off valve.
  (3)   Install proper controls. (Outdoor panels 

require 

NEMA 3R or 4X 

enclosure)

  (4)   All installations 

require 

a basin cover to prevent debris from 

falling into the basin and to prevent accidental injury.

  (5)   Cords must be properly sealed to prevent moisture and gases 

from entering the control panel. 

  (6)  

When check valve is installed

, drill a 3/16" (5mm) diameter 

hole in the discharge pipe below the check valve even with the 

top of the pump. NOTE: The hole must be below the basin cover 

and cleaned periodically. Also a vent hole is drilled in the pump 

housing. Be sure that this hole is cleared during any servicing.

  (7)   Vent gases and odors to the atmosphere through vent pipe per 

Local and State codes.
