Trouble-shooting Guide 

8.2 Division 1 Z-Purge Troubleshooting 

PROBLEM 

POSSIBLE CAUSE 

SUGGESTED SOLUTION 

The flow cannot be adjusted up to 

150 SCFH during purge 

Improper flow meter reading 

For correct operation, the purge 

unit must be mounted vertically so 

that the flow meter is vertically 

plumb 

Improper regulator adjustment 

Adjust the air inlet regulator to 

increase air supply 

The purge control is not set to 

purge 

Check the position of the control 

valve to ensure that it is set to 

“Purge” 

Insufficient air supply 

Check your purge gas supply to 

ensure that it can supply 150 SCFH. 

If you cannot achieve 150 SCFH, 

then purge times must be 

recalculated. Contact DAISY 

customer service for assistance. 

Restrictions in the air supply line 

Check your air supply line for 

blockages and kinks 

Contamination in the air supply 

Ensure that the purge gas supply is 

clean, dry, and free of oil – a 

water/oil separator should be 

installed near the connection to the 

purge control 

Restrictions in the purge line from 

the purge control into the 

enclosure 

Ensure that the purge line from the 

purge control into the enclosure is 

not kinked, has no internal 

obstructions, and is unrestricted at 

its open end (at least 0.5” from any 

object in the path of the air flow) 

During operation (control valve set 

to “Operate”), the internal 

pressure does not reach/will not 

maintain 1” of water column 

The enclosure is not sealed and is 

leaking 

Ensure that all access doors are 

closed and latched. Ensure that all 

access panels are closed and sealed. 

Make sure no unsealed holes or 

openings are present in the 

enclosure. 

Insufficient air flow 

Adjust the regulator on the purge 

control to increase the air flow 

Pack-Seals are not poured 

Pack-Seals must be poured in 

conduits entering the enclosure to 

prevent air from escaping via the 

conduit entry. Ensure that this has 

been done. 

Exhaust control valve setting 

incorrect 

Adjust the purge control exhaust 

valve for a higher internal pressure. 

It may take several minutes for 

adjustments to this setting to take 

effect.
