New Coolant Tank
(Small)
The MCX-1 has two tanks which are installed and connected from the rear. Quick
connect couplers are mounted on the hoses which connect these tanks to the MCX-1.
A green hose connects to the small New Coolant Tank and a black hose connects to
the large Waste Tank.
1. Slide the New Coolant Tank to the rear and sit it on the floor.
2. Remove the tank cap and fill the tank with new coolant and water in the
proportions specified by the coolant supplier. The tank can be disconnected
and moved to a bulk storage and fill area if desired.
3. Replace the tank cap and position the tank in the MCX-1. Make sure the green
hose is securely connected. Slide the tank to the front so the liquid level can be
seen through the front panel slot.
4. Fasten the clips on the tank strap to secure the tanks in the MCX-1.
