INITIAL START-UP

» 6. Tankless water heaters such as the Mini 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 Mini 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 ELECTRICAL 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 MINI 2-1, MINI 2.5-1, MINI 3-1, OR
MINI 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.

branch circuit of proper voltage rating. In installa tions with several
Mini 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.
4. Reinstall plastic cover.

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 MINI
!
DOES NOT CONTAIN ANY PARTS SERVICEABLE BY THE LAY
PERSON. IN CASE OF MALFUNCTION PLEASE CONTACT A LICENSED
PLUMBER OR ELECTRICIAN.
Stiebel Eltron Mini 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 Mini 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.
