Reverse the disassembly procedure.
6-4 Coolant Fill
A document describing an alternate procedure is provided in the coolant kit. For maximum safety and
minimum risk of spillage during coolant installation, we recommend using the procedure given below:
1. Before beginning, check the color of the coolant pro-
vided in the kit. It must be blue for a non-mobile sys-
tem.
2. Check that all hoses are correctly connected.
3. Remove the reservoir cap, then slowly add liquid
from the container labelled Topping to the reservoir
until the liquid reaches the bottom of the cap
threads. The total capacity of the cooling system is
approximately 500 ml (1 pint).
4. Switch on the unit (switch ON the MDR circuit
breaker and press the Conditioner ON button in the
generator cabinet).
5. As the coolant circulates and air bubbles are flushed
from the system, the coolant level falls. Add liquid as
necessary until the level is steady at the bottom of
the cap threads.
6. Replace the reservoir cap when you are satisfied
that the level is correct.
