1. Shipment inspection
Examine the components carefully to make sure no
damage has occurred to the pump during shipment.
Care should be taken to ensure the pump is NOT
dropped or mishandled; dropping will damage the
pump.
2. Pre-installation checklist
Before beginning installation procedures, the following
checks should be made. They are all important for
proper installation of the circulator pump.
1. Uses:
Model UP(S) 15 series pumps are designed to
circulate water from 36°F to 230°F (UPS 15-35 from
36°F to 165°F) up to a maximum pressure of 145 PSI.
If required, a 50% by volume solution of ethylene or
propylene glycol and water can be used, however, a
PSI decrease in pump performance may result due
to an increase in the viscosity of the solution. Check
with manufacturer for information regarding suitability
of pumping other fluids.
System applications:
UP(S)15 series pumps with
stainless steel or bronze volutes can be used in both
open and closed systems.
2. Maximum water temperature:
UP(S)15 pump with line cord only. The maximum
allowable water temperature is determined by the
ambient or surrounding air temperature as shown in
Table 2A.
Table 2A – Maximum water temperature

130
140

Water (°F)

Although the pump is designed to operate at
maximum water temperature of 230°F, it is recom-
mended to keep the operating temperature as low
as possible (i.e. below 140°F to avoid precipitation
of calcium).
Note: UP15(S) pump with timer control
maximum water temperature: 150°F
3.
Inlet pressure requirements
The amount of pressure required at the inlet of the
pump is a function of the temperature of the water as
shown in Table 2B.
