INSTALLATION INSTRUCTIONS

Mark the positions of mounting holes on the wall as the installation template shows (Fig. 1).
NOTE: For ease of installation and servicing, we recommend that this unit be installed in an up right position with the inlet and outlet water connections at the bottom.
Drill 4 mounting holes (Ø6x32mm) at the marked position (Fig. 2).
Put espansion boltes into the holes (Fig. 2).
Put two screws into the upper two holes (Fig. 3).
Remove the knob on front cover and 4 screws on the top and bottom edges of the unit, and then dismantle the front cover (Fig.4).

MOUNTING YOUR WATER HEATER

Hang the body on the two installed screws, then fix the other two screws. Tighten all 4 screws to secure the body.
NOTE: Make sure that the mounting surface is solid and firm, and ensure that the unit is level prior before tighten the screws (Fig. 5).
Reinstall the front cover after finish “PLUMBING INSTALLA-TION” and “ELECTRICAL INSTALLATION”. Fasten the front cover only after confirming that the mounting screws are firm and reliable. The front cover mounting shows as right (Fig. 6).
WARNING: The electrical compo-nents inside the water heater may cause serious personal injury or electric shock death. Make sure that the front cover is installed correctly and firmly. Do not remove the front cover unless installation or maintenance.
Screw the front cover to body. Reinstall the knob (Fig. 7).

PLUMBING INSTALLATION

CAUTION: The plumbing installation must be completed before the electrical installation.
WARNING: It is the responsibility of the Service Person to ensure that the water supply to the equipment is provided with protection against backflow by an air gap as defined in ANSI/ASME A112. 1.2-1979; or an approved vacuum breaker or other such method as proved effective by test.
