Indoor/outdoor area –
ensure draining through pressure relief
valve is available in order to avoid damage in case of leakage.
Outdoor area –
unit should be covered by a weather proof housing,
ensure adequate ventilation.
FREEZING (OR REMOVING PUMP FOR MAINTENANCE)
The pump and all piping must be protected
from freezing. If freezing weather is forecast, and the unit will be
exposed to temperatures less than 32 ºF (0 ºC), remove the pump by
closing off ball valves #1 and #2, (see FIG 1) and removing the pump
using the union connections. Store pump in a heated area. Open
ball valve #3 to allow city water to pass forward if desired. Ensure
the piping is adequately protected from the cold environment.
OPERATING CONDITIONS
Ambient temperature range 32 ºF (0 ºC) to 104 ºF (40 ºC).
PRIMING
After installation (with the pump OFF), open ball valves #1 and #2,
and slowly unthread the air relief plug (FIG 4). Allow inlet water
pressure to fill the pump cavity and remove in-line air pockets.
After the pump cavity fills with water, retighten the air relief plug.
FIG 4 PRIMING ILLUSTRATION
a. Open ball valves #1 and #2, close 3.
d. Tighten the air

If unit is shut down for an extended period of
time or air enters into the system, it may be necessary to repeat
the above priming instructions to ensure the internal pump cavity
is running with water to avoid dry running damage to the internal
seals.
