Atlantic Boilers ME STANDARD 180 운영 및 유지보수 매뉴얼

2.0 INSTALLATION

2.1

Procedure

-
Position the boiler squarely on the prepared base
-
Fit the correct accessories to the boiler connections
-
Connect the boiler to the pipework system
-
Connect the boiler to the isolated electrical supply
-
Fill the boiler with fresh, clean water
-
Check that the immersion heaters are electrically isolated from the boiler. If the isolation
is less than 2mega-ohms, the bridge must be found and rectified.
-
Check the operation of the main control panel isolator, and of the overloads serving the
immersion heaters
-
Check the operation and the correct direction of rotation of the circulating pump
-
Check, with the circulation pump stopped, that the water flow switch over-rides the
immersion heaters through their relays and also brings on the relevant alarm light
-
Check the setting and operation of the immersion heater step controls
-
Switch off the immersion heaters using the main control panel isolator
-
Check that all the cartridge fuses are sound
-
Double check that all the immersion heaters receive the common voltage.
Repeat the check after several hours run.
Any defect in voltage can destroy the heaters and invalidate the guarantee.
