Condensate Removal; Other - Aircel VF-10 Installation And Operation Manual

Aircel VF Series - Models 10 - 1200
1. High refrigerant readings generally indicate:
• Dirty condenser - Clean immediately!
• Dryer not turned on.
• Overloading - Airflow or conditions in
excess of dryer capacity.
• High ambient temperature (> 100°F)
Provide adequate ventilation for proper
cooling, or reduce ambient temperature.
• Condenser fan(s) not running - Call
Technical Support.
• Refrigerant control too high - Contact
technical support for assistance.
2. Low refrigerant readings generally indicate:
• Low ambient temperature - Temperatures
below 40°F. Increase ambient temperatures
or install head pressure control valve.
Contact technical support for more
information.
• Refrigerant control setting too low -
Contact technical support for assistance.
• Loss of refrigerant - Call Technical Support
or qualified refrigeration service.

Condensate Removal

The non-cycling refrigerated air dryer uses a
refrigeration circuit to cool the compressed air
which causes moisture to condense. The condensed
moisture is separated from the dry air and purged
through an automatic drain.
1. Condensate downstream of dryer:
• If the unit is equipped with automatic drain
override switch, push manual override
button to test drain flow.
• Ensure automatic electronic timer (if
applicable) is functioning properly.
• Ensure moisture separator (and
coalescer) drain lines are free from blockage.
20
• If the unit is equipped with y-strainer,
disassemble and clean.
• If oil is downstream from the dryer:
- Oil coalescer element is saturated.
- Dryer not turned on during air usage.
Before any service or maintenance
work is performed on the refrigerated
air dryer system, disconnect power
supply and lock out power supply and
depressurize system before performing
maintenance or service work.

Other

Sometimes a water or oil problem downstream
from the dryer can be identified by an inadvertent
action or inaction by the operator.
• Dryer not turned on before air usage.
• By-pass valves in wrong position.
• Air usage exceeding dryer capacity.
• Oil coalescer element dirty.
• Automatic drains not maintained.
