Positioning the Minivap unit

 

 

DO's

 

 

DO

 mount the unit indoors.

 

 

DO

  mount  the  unit  close  to  the  steam  nozzle 

position.

 

 

DO

 ensure adequate service access to the front of 

the unit -min. 70Omm (2'3").

 

 

DO

  remove  the  cylinder  to  gain  access  to  the 

mounting holes in the back of the steam section.

 

 

DO

 use M6 projecting type wall bolts or equivalent 

to mount the unit in position.

 

 

DON'Ts

 

 

DON'T 

install  the  unit  close  to  sources  of  strong 

electromagnetic  emissions  e.g.  variable  speed  lift 
motor drives, KVA transformers, etc.

 

 

DON'T

 mount unit in an unventilated enclosure.

 

 

DON'T

 mount in a position requiring ladder access 

to the unit.

 

 

DON'T 

install the unit behind a false ceiling or other 

situation  where  an  unusual  malfunction  (e.g.  water 
leak) would cause damage.

 

 

DON'T 

install the unit in an area which will be 

hosed down.

 

 

DON'T

  install  the  unit  where  the  ambient  air 

temperature can exceed 35°C (95°F).

 

 

DON'T

  mount  the  unit  inside  a  cold-room  or  other 

place  where  temperature  and  humidity  conditions 
can cause condensation on electrical components.

 

 

DON'T

  mount  the  unit  where  the  sound  of  a 

contactor  opening/closing  and  water  flow  in  a  pipe 
would  be  unacceptable  e.g.  libraries,  private 
apartments, etc.

 

 

DON’T

 place any object in front of an RDU (if used) 

where humidity conditions can cause condensation.

 

 

DON’T

 mount on a duct or plenum.
