ITT Laing E-10 & E-14 Circulation Pump Installation, Operation and Warranty Manual
(To be read / used in conjunction with E series pump manual)
Unpacking
when unpacking the unit, inspect carefully for any damage that may have occurred in transit.
Check for loose, damaged or missing parts. Any problem - contact the supplier purchased through immediately. Do
not attempt to repair or modify in any way or warranty may be void.
Installation
These pumps have been evaluated and authorized for water use only in spa / pool applications. Ensure the power
source is correct depending on which voltage pump you purchased and 60Hz. Ensure installation is in a clean, dry,
weather & humidity protected location with adequate air ventilation. Ambient temperature not to exceed 110
degrees F. Ensure the power cord is run in such a way that any water that may get on it, cannot run down the cord
to the motor. This unit cannot be submerged - ensure it cannot flood. Protect cords from sharp objects, hot
surfaces; avoid kinking or coiling of the cord. Replace damaged cords immediately. Locate pump as close as
possible to the fluid source thus making the suction line as short and direct as possible, using tubing on the suction
that cannot collapse, such as a reinforced type. Support the tubing independently of the pump. Use clamps to
secure and seal the tube to the pump. Laing pumps are liquid lubricated. How they are mounted and water
condition are important. Thoroughly clean and flush the system before installing the pump Plumbing valves,
fittings, etc. should be positioned to avoid leakage onto the pump. Ensure plumbing is designed and installed in
such a way that the pump will fill with water when the plumbing system fills, to avoid air locking and dry running.
Mounting
For installation purposes, the arrows on the side of the pump housing indicate the direction of water flow through
the pump. Ensure the pump and piping is adequately supported. Do not mount the motor above the wet end.
Correct orientation of the pump includes mounting horizontally or vertically with suction facing upward only. The
pump can roll on its foot to allow different angles of discharge alignment. Do not position with discharge port
lower than inlet / suction port. This helps prevent air locking.
