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.
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, 26, 43 and 50 series pumps
are generally designed to circulate water from 32 deg F to
230 deg F up to a maximum pressure of 150 psi.
Some
models have temperature limitations which are shown
in Table 2A below.
If required, a 50% by volume solution
of ethylene or propylene glycol and water can be used,
however, a 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.
Closed Systems: Model UP(S)15, 26, 43 and 50 series
pumps with cast iron pump housings are designed to pump
water compatible with their cast iron construction. They
are recommended for use in closed hydronic systems.
(i.e. airless, non-potable water).
Open Systems: Model UP(S)15, 26, 43 and 50 series
pumps with stainless steel or bronze pump housings are
designed to pump water compatible with their construction
and can be used in both open and closed systems.
2. Maximum Water Temperature:
The maximum
allowable water temperature is determined by the ambient
or surrounding air temperature as shown in Table 2A.
