UP Series

Materials of construction Installation
The pump must always be installed with horizontal
motor shaft.
Proper installation of the pump will have the terminal
box located to one side of the pump or the other, with
the conduit entry down.
UP can be installed in both vertical and horizontal lines.
UP pumps are intended for indoor use only.

Motor
The motor is a 2-pole asynchronous squirrel-cage PSC
(permanent split capacitor) motor with UL, CUL, and
CSA approvals.
UP pumps are available in single-phase 115 V and
230 V versions with one or three speeds.
The terminal box is easily accessible and has functional
cable connecting leads or terminals.
Insulation class: F.
The motor incorporates thermal overload or impedance
protection. Therefore, no external motor protection is
required.
UP models are single - speed.
UPS model pumps are multi-speed, and the speed can
be changed by a speed selector switch located on the
front of the terminal box.
If the speed of UPS 15-35 or 15-55 TLC models has to
be changed, the timer control has to be removed before
the speed can be changed.
UP models with VS or MR suffixes are variable-speed
with integrated control.
Motor horsepowers range from 1/25 to 1/6 and power
consumption from 25 to 385 W.
