Active Aqua Pumps from Hydrofarm are carefully inspected and tested to ensure
both safety and operating performance. However, failure to follow the instructions
and warnings in this manual may result in pump damage and/or serious injury. Be
sure to read and save this manual for future reference.
WARNING
• This pump is supplied with a grounding conductor and a grounding type
attachment plug. To reduce risk of electric shock, connect only to a properly
grounded outlet.
• Do not remove the grounding pin from the plug.
• Do not connect to any voltage other than that shown on the pump.
• Do not pump flammable liquids.
• The national electric code requires that a grounded fault circuit interrupter
(GFCI) be used in the branch circuit supplying fountain pumps and other pond
equipment. See your electrical supplies dealer for this device.
• Do not use with water above 86°F (30°C).
• Do not allow the pump to freeze in winter, remove pump from fountains and
ponds and store in a frost-free area.
CAUTION:
Always disconnect from electrical outlet before handling the pump.
• Do not let the pump run dry.
• Do not lift the pump by the power cord.
• Do not pump heated liquids.
• Do not operate in salt water.
PERFORMANCE
• A clogged or dirty intake screen will greatly reduce performance. If the pump
is used on a dirty surface, raise it slightly to reduce the amount of debris
contacting the intake. If less flow is desired, adjust the flow control knob on the
front of the pump or restrict the discharge flow.
• Active Aqua submersible pumps can be used submersed or in-line (except for
models AAPW40 and AAPW160, which are for submersed use only). Note that
when used in-line it should be placed below the water level since it is not self
priming. Never run this pump dry. If initially the pump does not work, it may be
“air locked”. To clear the air lock, unplug the pump and tilt 90° degrees under
water, repeat if necessary.
The included gray fitting should be attached to the inlet side of the pump only when
operated in-line. The barbed gray and black fittings use a different sized thread and
rubber o-rings. The gray in-line fitting attaches to the front of the pump and uses
the larger sized o-ring. The black fittings attach to the top of the pump and use the
smaller sized o-ring. Please use only as intended (see chart for reference).
