CCS Fan and VACUMETER™ Hydraulic Requirements
IMPORTANT:
Damage to VACUMETER
™
can occur if VACUMETER
™
return lines are connected incorrectly.
IMPORTANT:
CCS fan and VACUMETER
™
fan case drain hose MUST be attached to low-pressure drain connection PRIOR to inlet and return hoses being connected. Case drain MUST have LESS THAN 172 kPa (1.72 bar) (25 psi) or fan motor will be damaged.
The hydraulic motors used on the CCS fan motor and VACUMETER
™
are a low flow, high pressure motor and are designed to operate on a closed-center hydraulic system. If an operator attempts to connect a CCS fan motor or a VACUMETER
™
directly to an open-center hydraulic system, the fixed displacement pump in an open center system will send most of the hydraulic oil over the relief valve. This will produce too much heat for most tractor oil coolers to dissipate. Connecting the CCS fan or the VACUMETER
™
to an open-center system is not recommended. See your John Deere dealer for more information.
