INSTALLATION
INITIAL STARTUP
» 4. Install isolating valve in cold water line as shown in
illustration . This allows the unit to be isolated for
C
maintenance purposes.
» 5. Cold water connection (inlet) is on the right side of the
unit, hot water connection (outlet) is on the left side of unit.
» 6. Tankless water heaters such as the AQM are not required
to be equipped with a Pressure and Temperature Relief
Valve (except in Massachusetts). If the local inspector will
not pass the installation without a P+T valve, it should be
installed on the hot water outlet side of unit.
» 7. The AQM is designed for connection to a braided
stainless steel hose with a 3/8" OD Tube Outlet.
» 8. When all plumbing work is completed, check for leaks
and take corrective action before proceeding.

Electrical connection

WARNING: BEFORE BEGINNING ANY WORK ON THE
ELECTRIC INSTALLATION, BE SURE THAT THE MAIN
CIRCUIT BREAKER PANEL SWITCH IS "OFF" TO AVOID ANY
DANGER OF ELECTRIC SHOCK. FAILURE TO DO SO MAY
RESULT IN SERIOUS INJURY OR DEATH. ALL MOUNTING AND
PLUMBING MUST BE COMPLETED BEFORE PROCEEDING
WITH ELEC TRICAL HOOKUP. WHERE REQUIRED BY
LOCAL, STATE OR NATIONAL ELECTRICAL CODES, THE
CIRCUIT SHOULD BE EQUIPPED WITH A GROUND FAULT
INTERRUPTER.
WARNING: AS WITH ANY ELECTRIC APPLIANCE, FAILURE
TO ELECTRICALLY GROUND UNIT MAY RESULT IN
SERIOUS INJURY OR DEATH.
CAUTION: INSTALLING A AQM 21, AQM 2.51, AQM 31,
OR AQM 3.51 ON A 208 V OR 220  240 V CIRCUIT WILL
DESTROY THE HEATING ELEMENT. THIS IS CONSIDERED
IMPROPER INSTALLATION AND WILL VOID YOUR
FACTORY WARRANTY.

1. All electrical work must comply with national and applicable
state and local electrical codes.
2. The AQM should be connected to a properly grounded
dedicated branch circuit of proper voltage rating. In installa-
tions with several AQM units, each unit requires an independent
circuit. Please refer to the technical data table for the correct wire
and circuit breaker size.
3. The open ends of the "pigtail" must be feed into an electrical
junction box. Then feed wires through strain relief clamp and
tighten clamp down on wire.

Water heater hand over

1.
Explain the functions of the unit to the user and familiarize him
or her with its use.
Important instructions:
°C
» Draw the user's attention to possible hazards (scalding).
» Hand over these instructions for future reference.
» In order to obtain a proper temperature at a single spout
electronic electronic
mixer-type faucet, restrict cold water fl ow to faucet by
partially closing the cold water shut-off valve under the sink
until cold water and hot water fl ow rates are approximately
the same.

10. Normal maintenance

CAUTION: OTHER THAN THE FILTER SCREEN, THE
!
AQM DOES NOT CONTAIN ANY PARTS SERVICE-
ABLE BY THE LAY PERSON. IN CASE OF MALFUNCTION
PLEASE CONTACT A LICENSED PLUMBER OR ELECTRI-
CIAN.
Aqua Power AQM tankless heaters are designed for a very long
service life. Actual life expectancy will vary with water quality
and use. The unit itself does not require any regular maintenance.
However, to ensure consistent water fl ow, it is recommended
to periodically remove scale and dirt that may build up at the
aerator of the faucet or in the shower head. Also, the AQM has
a built in fi lter screen that should be cleaned from time to time.
In order to do this, turn off the cold water supply at the isolating
valve. Clean screen and put the screen back into its original
position.
