If an air receiver tank will be used with this system, a check valve
(not supplied) must be installed to prevent damage to the system.
Once a check valve is installed, pressure in the air receiver tank will
not be relieved when the compressor system blows down. This is
normal operation.
Prior to performing any service work on the system, discharge any
stored air in the air receiver tank.

If an air receiver tank will be used with this system, the following
installation procedure must be used to prevent damage to the
system.
The VMAC compressor system will automatically depressurize when it is shutdown,
therefore the hose from the VMAC AOST to the air receiver tank must have a
check valve installed; this prevents blow back and moisture from the receiver tank
entering the AOST
While the air receiver tank can be installed at any height in relation to the AOST,
the discharge hose running from the AOST must be installed as high as possible
on the air receiver tank to prevent problems with condensation that may have
accumulated in the receiver tank (Figure 51).
Drain the condensed water from the receiver tank daily.
