Operation; Priming Pump - Flotec AT250701 Manual Del Usuario

Operation

NOTICE: NEVER run pump dry. Running pump dry may
damage seals, causing leakage and flooding. Fill pump
with water before starting motor.
Before removing trap cover:
1. STOP PUMP before proceeding.
2. CLOSE GATE VALVES in suction and discharge pipes.
3. RELEASE ALL PRESSURE from pump and piping
system.
If pump is being pressure tested, be sure pressure
has been released before removing trap cover.
Fire and burn hazard. Modern motors run
at high temperatures. To reduce the risk of fire, do not
allow leaves, debris, or foreign matter to collect around
the pump motor. To avoid burns when handling the
motor, let it cool for 20 minutes before trying to work on
it. An automatic internal cutoff switch protects the motor
from heat damage during operation.

Priming Pump

Release all pressure from filter, pump, and piping system;
see the filter owner's manual.
In a flooded suction system (water source higher than
pump), pump will prime itself when suction and dis-
charge valves are opened.
If pump is not in a flooded suction system, unscrew and
remove trap cover (see Figure 5); fill trap and pump with
water.

Hazardous Suction.
Can trap hair or body,
causing severe injury
or death.
• Do not block suction.
• Keep small children
under close adult
supervision at all times.
BOARD
Do not lubricate the trap cover O-Ring. The original
equipment O-Ring contains a permanent internal
lubricant.
NOTICE: If you replace the O-Ring with a non-internal-
ly lubricated O-Ring, you may need to apply a silicone
based lubricant.
Clean and inspect O-Ring; reinstall on trap cover.
Replace trap cover on trap; turn clockwise to tighten
cover.
NOTICE: Tighten trap cover by hand only (no wrenches)!
Pump should prime now. Priming time will depend on
vertical length of suction lift and horizontal length of
suction piping.
If pump does not prime, make sure that all valves are
open, suction pipe end is under water, pump is not trying
to lift water more than 10' (3m), and that there are no
leaks in suction pipe. See Troubleshooting, Page 11.
Storage/Winterizing:
NOTICE: Allowing pump to freeze will damage pump
and void warranty!
NOTICE: Do not use anti-freeze solutions (except propy-
lene glycol) in your pool/spa system. Propylene glycol,
"RV antifreeze", is non-toxic and will not damage plastic
system components; other anti-freezes are highly toxic
and may damage plastic components in the system.
Drain all water from pump and piping when expecting
freezing temperatures or when storing pump for a long
time (see instructions below).
Keep motor dry and covered during storage.
To avoid condensation/corrosion problems, do not cover
pump with plastic.
For outdoor/unprotected installations:
1. Enclose entire system in a weatherproof enclosure.
2. To avoid condensation/corrosion damage, allow ven-
tilation; do not wrap system in plastic.
3. Use a 40% propylene glycol/60% water solution to
protect pump to -50°F (-46°C).
