BATTERY CARE
For maximum battery life, do not fully discharge the battery. Avoid operating or charging
the unit in extreme temperatures. If the battery life decreases by a significant amount, send
the unit back to Mastercool to replace the batteries.
CLEANING THE VACUUM SENSOR
1. Disconnect the hoses from the manifold.
2. Being very careful not to spill on the manifold, fill it with system flush (Mastercool A/C
Flush Solvent 91049-32 or other solvent into the manifold) through one of the fittings.
3. Close the valves and shake the manifold to distribute the solvent and let the manifold
set for a few minutes.
4. Drain the solvent into a suitable container.
5. Hook the manifold up to a vacuum pump and draw a vacuum on the manifold to dry it
out.
6. Repeat as necessary.
Note: If the vacuum sensor continues to not read correctly, return to Mastercool for repair.
