- Page 2 ® What is a Liqui-Mover Pump? A Liqui-Mover pump is a positive displacement pressure powered pump with a minimum of moving parts. The pumping action is accomplished using a positive pressure to push the liquid from the pump tank into the return line.

Page 3: Installation
Installation Receipt of Equipment The float assembly has been adjusted and tested at the factory. Additional items such as the inlet baffle (if supplied), check valves, level gauge glass, cycle counter, and insulation jacket will be packaged separately in a carton shipped with the unit. Setting the Unit On LOOO models, the pump tank may be anchored to the floor using the holes in the mounting feet. - Page 4 Pressure Reducing Valve Installation A pressure reducing valve (PRV) should be installed in the motive pressure line to regulate how fast the Liqui-Mover pump discharges the condensate out of the pump tank. Normally the motive pressure setting will be approximately 20 psig higher than the back pressure to achieve a proper discharge time. The dis- charge time should be a little less than the time it takes to fill the pump tank under maximum condensing load.

- Page 7 Start-Up Instructions For LMHT-500 Liqui-Mover Pump 1. On systems that are not pre-piped, inspect the inlet and outlet check valves for proper flow direction. Refer to the Liqui-Mover pump assembly drawing and parts list. 2. If the receiver or pump chamber contains sub-cooled condensate, this needs to be drained prior to start-up.
