Startup Checklist

 

  

 

Before  starting  the  “ERDDR”  PURE  Humidifier  Co.  Electric  Humidifier,  check  the  following  installation 

 

items:

 

  

______

 

1.

 

  MOUNTING 

-

  Verify  that  the  humidifier  evaporating  chamber  is  securely  supported  and  that  the 

 

evaporating chamber is level in both directions.  If humidifier is installed above equipment or not located 

 

near a floor drain than a drain pan should be installed below the humidifier steam generator.

 

  

______

 

2.

 

 

 

INJECTION TUBE 

-

 Verify that the humidifier injection tube is mounted within the duct with the proper 

 

pitch back to the humidifier (2”/5 cm per foot / 31 cm).  NOTE: If the humidifier evaporating chamber or 

 

the flexible hose (optional) is mounted higher than the injection tube, a drain “tee” is required to drain the 

 

condensate out of the injection tube steam line.  If it is an Insty

-

Pac or Fast

-

Pac, refer to the 

 

respective 

 

O&M to determine if they are mounted properly and have the proper p

-

trap size.

 

 

______

 

3.

 

 

 

ELECTRICAL 

-

  Verify  that  all  wiring  connections  have  been  connected  in  accordance  with  the  wiring 

 

diagram.  

CAUTION: Live power may exist in the control cabinet.  Turn off the main power at the 

 

disconnect switch before verifying the electrical connections!

 

 

______ 4. 

 

SAFETY  CONTROLS  –  The  supply  air  duct  RH  high

-

limit  should  be  installed  at  least  10  feet 

 

downstream  from  the  humidifier  tube.    Any  other  control  sensors  should  be  at  least  10  feet 

 

downstream  from  the  humidifier  tube.    Smoke  detectors  should  not  be  installed  downstream  of  the 

 

humidifier  tube.    If  a  smoke  detector  absolutely  has  to  be  installed  downstream  from  the  humidifier 

 

tubes then it should be installed as far from the tubes as possible.

 

  

_____

 

5.

  

PIPING: Water Supply 

-

 Verify that all piping connections have been completed as recommended and 

 

that  water  pressure  is  available  to  the  humidifier.    Verify  that  the  supply  water  pressure  is  35

-

50  psi. 

 

There should be at least 5 feet of metal pipe and check valve between the tank and any plastic pipe.

 

 

_____

 

6. 

 

PIPING:  Steam  Outlet 

-

  Refer  to  attachment  for  proper  outlet  steam  piping  from  the  generator  to  the 

 

tube(s).   

Any horizontal to vertical up transition in the outlet steam pipe requires a water

-

sealed 

 

drip leg!  

Improper outlet steam piping will cause steam to leak from the steam generator.  Runs over 

 

20 feet long may require upsizing of the steam pipe.
