Continuation 1.2 Operating safety instructions
The standard version of the
heat exchangers is designed
for an operating pressure of
145 psi (test pressure 232 psi).
High water pressures may be
hazardous. Higher operating
pressures, therefore, require
LTG's express permission.
Wear safety glasses.
Parts and tools.
Be careful when working
overhead and provide pro
tection against parts falling
from above.
Keep objects and dirt from entering the im
peller. A damaged fan impeller or objects
being ejected by the impeller may be haz
ardous.
Never remove the protective grille of the fan
impeller and the motor cover during opera
tion.
The casing on site also serves as a protection
and should be removed for maintenance and
cleaning only.
Avoid any additional load to the unit or the
suspensions since stability might be insuffi
cient.
The unit must be checked by an expert
immediately:
- if it has been mechanically damaged
- if it is suffering from a water damage,
- if the fan shows signs of damages (imbal
ance, damage to the bearing or motor)
- if the suspension or the casing show clear
signs of corrosion or ageing.
Do not put the unit back into operation before
all necessary maintenance and repair has
been performed by an expert !
Take the unit entirely off the main power sup
ply until all repairs have been completed by
an expert even if this might result in not being
able to operate undamaged units.
It is in any case imperative to take a damaged
unit completely off the main power supply!
