A. Weekly Checklist
1. Check Air-Cooled condenser coil for contaminants and
clean as required. Check Water-Cooled condenser coil for
proper water flow.
2. Inspect all electrical drains for operation. Turn off the shut-
off valve and depress the manual override switch on the
electrical valve, this will depressurize the discharge line,
and clean the “Y” strainers.
3. Assure dryer inlet temperature does not exceed 120°F
(48°C).
4. Assure dryer ambient temperature does not exceed
110°F (43°C) and there are no ventilation obstructions
around the dryer. Ventilate the area and remove
obstructions as required.
5. Check separator, receiver, filter drains and strainers.
Check filter high differential pressure indicators, and
replace fouled elements as needed.
B. Semi-Annual Checklist
1. Remove and inspect all air system filters for excessive
particulate loading and physical damage. Replace the
filters that show any sign of damage, or if pressure drop
exceeds 7 psid (0,5 bar).
2. Shut off drain shut-off valves and clean “Y” strainers.
Disassemble solenoid valves if necessary and check for
contaminants. Clean as required.
