SG Series Model

    6.2.7 DRY-OUT TIME          

   unicells and filter media should be dry before the SG 

is placed into operation. Startup of a wet system will 

cause dead short conditions to the ionizer and collector 

cell circuits. Wet unicells and filter media should be 

placed in a warm room for drying.  Techniques such 

as hand wiping insulators and blow drying unicells and 

filter media with compressed air will decrease drying 

time.  another method for drying cleaned components 

is installing the unicells and filter media in the SG and 

placing on the system blower on line, with all power 

pack enclosure toggle switches placed in the “off” 

position for 30 minutes. 

7. MANUAL CLEANING METHODS 

   the manual cleaning method selected will depend 

on the type of contaminant, rate of deposit, facility 

limitations such as cleaning time windows (process 

downtime) and available utilities. all cleaning methods 

listed in this section are acceptable. 

7.1 SOAK TANK             

   this method involves placing unicells and filter media 

in an agitated solution of hot water and detergent and 

is the most effective method. With proper detergent 

selection, this procedure will quickly remove most 

contaminants.  unicells and filter media should not be 

placed in highly concentrated detergent solutions or 

allowed to soak for extended periods, (e.g., overnight), 

especially at elevated temperatures.  Extended soaking 

(e.g., days) in solvent or detergent solution will 

degrade components over time and should be avoided. 

7.2 PORTABLE PRESSURE WASHER         

   a self-contained pressure washer with a spray wand 

can be an effective cleaning method, providing it is 

used with caution.  Care should be taken not to expose 

the unicells to close-up and prolonged blasts of high 

pressure/temperature, causing cell plate deformity, 

requiring a replacement set of unicells and filter media. 

7.3 AUTOMATIC PARTS WASHERS         

   certain commercially available units combine and 

automate the features necessary for effective cleaning, 

including water heating, detergent injection, agitation, 

rinsing and drying. 

7.4 OTHER CLEANING CONSIDERATIONS 

   the previous methods address the cleaning of 

unicells and filter media. the SG cabinet should also 

be periodically cleaned (i.e., during normal planned 

downtimes) to reduce contaminant build up.  High 

voltage output of the power packs should also be 

checked when manual cleaning is performed. 

 8.  APPEARANCE OF COMPONENTS 

AFTER CLEANING 

   components should have a clean, not necessarily 

“new,” aluminum appearance.  Moderate discoloration 

will not affect system efficiency. checklist for acceptable 

components. 

8.1 UNICELL 

     1.  frame, end plates and cell plates are free of 

contaminant build-up (residual contaminant has 

been removed between plates and at comer 

supports). 

     2.  The frame is square, cell plates are parallel and 

cell hot plates are centered between ground 

plates. 

     3.  ionizer standoff insulators and cell triangular 

insulators are cleaned (no residual coating). 

cracked or carbon-tracked insulators have been 

replaced.   

     4.  ionizing wires and springs are intact and taut, 

centered between plates and free of coatings. 

     5.  contact springs and contact screws are properly 

located, and replace missing contact hardware. 

refer to figure 20. 

     6. contact springs are not deformed. 
     7.  Bent or broken parts have been repaired or 

replaced. 

8.2 PRE-FILTERS/AFTER-FILTERS 

     1.  aluminum media and frame are free of 

contaminant. 

     2. Frame is square and media is intact. 
     3.  filters are always installed with drain holes down 

and arrow on each frame pointing in the direction 

of airflow 

8.3 CABINET 

     1. Door feed-thru insulators are cleaned and white. 
     2. Door gaskets are cleaned and intact. 
     3.  component tracks are free of contaminant build up 

(for unicell grounding). 

     4. Module drain sumps are cleaned and free-flowing. 
     5. Interior is free of extreme contaminant build-up. 
     6.  Blower wheel and housing is free of extreme 

contaminant build-up.  

     7.  Preconditioning equipment, if so equipped, (inlet 

plenum with baffle filters, cooling coils, etc.) 

has been checked for excessive pressure drop, 

cleaned if necessary. 

     8.  nozzles on all in-place cleaning system headers, 

if so equipped, are not plugged.
