General Maintenance - Bosch ACS 561 Repair Instructions

Introduction

General Maintenance

Wipe off the machine often using a clean cloth
to remove grease and dirt.
Electrical Protection
The machine is equipped with a circuit breaker
on the control panel above the ON/OFF switch.
If the breaker trips, its button will pop out. A
tripped circuit breaker will cause the machine
to lose all power. Press the circuit breaker but-
ton to reset. If the circuit breaker does not reset
or continues to trip, there is a fault in the unit
electrical system. Troubleshoot and repair the
affected component(s).
Check for Leaks
The machine checks internal components for
leaks after the initial setup and every 10 days.
Over time, fittings loosen as the machine is
moved.
The machine also checks for internal leaks each
time a filter is replaced.
1. When prompted, connect both service
hoses to their storage ports.
2. Open both coupler valves.
3. Press F1 to perform the leak test.
To perform a manual leak test:
1. Turn OFF the main power switch, and dis-
connect the power cord from the outlet.
2. Remove panels as necessary to use a
leak detector to probe all connections for
refrigerant leaks. Tighten fittings if a leak is
indicated.
3. Reassemble body panels.
