ABC-600
through a drain tube that empties through the bottom of the cabinet near the front.
The drain tube is flexible and can be guided through the open front of the cabinet
into an appropriate receptacle. Once you have located the drain valve and directed
the drain tube, open the valve and let the coolant drain.
•
After all of the coolant mixture has drained, close the valve and proceed to refill the
coolant as described in Section 3, Installation.
•
Dispose of the coolant according to local, state and Federal regulations.
Check coolant system for leaks and aging hoses every six months.
•
Coolant leaks are not expected in normal operation. However, if a coolant
leak does develop, it may damage the system or even cause potentially
dangerous conditions for users.
DANGER
To check the coolant system, first open the AC side front panel and remove the
reservoir cap. Look into the reservoir to check the coolant level. If the
reservoir appears full, coolant leaks are unlikely to have developed.
To check the remainder of the coolant system, open the front and lower panel as
•
necessary to access all hoses and fittings, as well as the pump assembly. Touch the
fittings and connection points to see if any moisture is collecting. Look for other signs
of leakage such as residue from evaporated coolant drops or streaks. Also check
the cooling system hoses for cracks or hardening.
If a leak appears to have developed, DO NOT OPERATE THE ABC-600. Note the
•
leak location and then drain the coolant from the system as described above.
Tighten or replace any loose fittings. Replace any hoses that are damaged. If a leak
is found in the pump, the heat sink, or the reservoir, contact Webasto's Customer
Service Department for service or replacement parts. Once these procedures have
been completed, refill the coolant system with Webasto approved coolant and allow
it to stand for an extended period of time, checking frequently for leaks. When the
leaks have been fixed, replace all side panels and resume operating the system.
Calibrate DC Output Current once per year. The output current of the DC
•
Converter is automatically recalibrated as the system operates. However,
over time, typical component aging can cause current accuracy to drift.
Follow the Current Calibration/Voltage Verification Instructions available from
Webasto's Customer Service Department. Ripple currents can be verified at
this same time. However, it is important that the load used when measuring
ripple current is NOT a second ABC-600 system. Use a battery or resistive
load to obtain accurate ripple measurements.
