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

Ambient (°F) 95 130 140 160 175

Water (°F) 230 220 210 190 175

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.
