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(S) can be installed in both vertical and horizontal
lines.
UP(S) 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,
ETL and CSA approvals.
UP(S) 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 cables connecting leads or terminals.
Insulation class(es): F, H.
The motor incorporates thermal overload or
impedance protection. Therefore, no external motor
protection is required.
UP models are single-speed pumps.
UPS model pumps are multi-speed pumps, and the
speed can be changed by means of 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
pumps with integrated control.
Depending on pump model, motor horsepowers range
from 1/25 to 1/6 and power consumption from 5 to 385
W.
