PSH Series Model

8.4 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 ionizer and collector cell 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 (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 are

not plugged.

9. PART REPLACEMENT

PROCEdURES ANd AdJUSTMENTS

9.1 Ionizer Wire(s) Replacement

   refer to figure 16.
   1. remove damaged wire from each spring.
   2. replace spring if damaged or missing.
   3.  Loop one end of new wire over bottom spring.

Pull top wire loop with pliers over top spring.

4. Wire should now be taut and centered.

If replacement parts are not available, remove

broken wires and tension springs from the ionizer

until parts are available. The ionizer can be

placed in service with missing ionizer wires.

9.2 door Feed-Thru Insulator(s)

Replacement

   1. Place system off line.
   2. open power pack enclosure lid cover.
   3.  remove high voltage wire by removing #10-32 hex

nut.

4. remove insulator retaining nut.
5. open module door and remove the long screw from

the insulator.

6. remove the insulator from the interior of the module

door.

7. clean silicone sealant from module door surface.
8. install replacement insulator, reversing the procedure,

and applying a thin coat of silicone sealant to base of

insulator.

9.3 Indicator Light Replacement

1. open the power pack enclosure lid cover.
2. Disconnect the red and black wires from the indicator

light which is connected to wires “9” and “2”.

3. remove indicator light installation nut. the indicator

light located on each power pack enclosure is polarity

sensitive. for proper operation, the two wires from

the indicator light should be connected as follows,

red wire connected to “9” wire from the power pack,

black wire connected to “2” wire from the power

pack. if the wires are reversed, the indicator light will

not illuminate. the power pack indicator light circuit

is Dc voltage.

4. install the replacement indicator light reversing

the procedure.

9.4 COMPONENT ACCESS dOOR(S)

GASKET REPLACEMENT

Before adjusting for gasket deflection, check for the

following:

   1. Door or cabinet damage.
   2. Deformed or torn gasket.
   3.  Leakage from some other source. ionizers and

collector cell components should be removed and

replaced with great care to preserve gasket integrity.

Should damaged gasket require replacement, contact

united air Specialists for the correct gasket material,

Buna-n (42-1535) or ePDM (42-10024-0001).

a component door requires 7 feet.
