Maintenance and Trouble Shooting
The pump does not turn on
• Ensure the timer slide switch is set to the “ON” position or the “ ” position,
that the timer clock is programmed to allow operation; and that there is power
to the outlet.
• If the pump is installed under a kitchen sink, make sure the outlet is not
controlled by a wall switch (i.e., garbage disposal).
The pump is noisy when on
• Turn off the Autocirc pump. Turn on the hot and cold faucets/taps to be sure
all air is purged from the system.
• If the noise continues, unplug the pump and turn off the faucet/taps
shut-off valves. Remove the pump from the wall bracket, loosen the screw ring
to separate motor from the pump housing and check for any foreign matter in
the rotor cavity. Also ensure the rotor is properly set on the motor bearing by
pushing down on the rotor.
• If a noise occurs when the pump turns off it is likely to be “water hammer”
that results from the closure of the built-in valve. In this situation, water
hammer arresters may be installed on the hot and cold lines.
Hot water is not instantly available at all my faucets/taps
• Instant hot water will be available at all the hot water faucets/taps on the
main plumbing line between the water heater and the faucet/taps under which
the Autocirc system is installed. Hot water faucets/taps that are “branched”
off this main hot water supply line will take longer for the hot water to arrive,
however, usually faster than before installing the Autocirc.
I am away from my home for extended periods of time (2 weeks or more)
• You may chose to turn the system off (slide the timer switch to the “OFF”
position) as there is no need to maintain hot water in the supply line when no
one is home to enjoy this convenience. When returning home, prior to turning
on the system, we recommend that you turn on the hot and cold faucets/taps
at the sink where the Autocirc system is installed until all air is purged from the
dormant system and the water flows smoothly from the faucets/taps. Then slide
the timer switch back to either the “ON” or “ ” position.
Warranty
The Autocirc is warranted against defects in materials and workmanship for
twenty-four (24) months from the date of manufacture (see the manufacturing
date label on the pump) or twelve (12) months from the date of user purchase,
with proof of purchase, whichever is sooner. In order to receive warranty
considerations, the product must be returned prepaid to the company from
which it was originally purchased. If the Autocirc is found defective within
standard warranty conditions, it will be replaced or appropriate purchase credit
will be issued.
Any consequential damages resulting from an Autocirc defect or malfunction
are not covered by the Laing warranty. Any ancillary item(s) included with your
Autocirc purchase, such as a flexible hose(s), is specifically excluded from the
ITT Laing Thermotech warranty.
