Motorized valve and control
• If these connections are not made as described the drain
pan condensate may overflow.
• Valves should only open when the fan motor is working, i.e.
when one of TB1 terminals 1 or 2 or 3 is supplied from TB1
terminal 4.
• The optional electric heater (mod. 42GWE) which can only be
factory installed, must only be energized when the fan is
working.
• The optional electric heater which must be factory installed on
model 42GWE, works only if TB1 terminals 5-6 are supplied
from TB1 terminal 4.
• The water discharge pump should work every time the
cold water valve is opened, supplying TB1 terminal 7 and
8 from TB1 terminal 4.
• When the system is filled with water, verify all couplings
for tightness.
• The manufacturer does not accept responsibility for the
tightness of the field - installed valve assembly and this
is not tested in the factory. He declines any responsibility
for non functioning of these assemblies and for damage
due to dripping.
