Clorius Controls V2 Instrucciones página 7

Fig. 2 indicates for each thermostat type (column
I) and temperature range (column II), the height
by which the piston should protrude above the
bushing (211), at a sensor temperature of 20°C
(column III). For temperatures above 20°C, the
protrusion must be increased by the amount the
piston would move as per column V. As a guide,
column IV gives the approx. distance from the
top of piston to the O-ring. It may be necessary
to remove the piston and move the packing
ring up or down before the correct protrusion is
achieved.
Important: For temperature range 60-120°C, it is
necessary to top up the cylinder at a temperature
higher than 20°C. The details shown in the table
for this range apply to a sensor temperature of
35°C.
The fluid system must not contain air. If firm
pressure on the piston causes it to move more
than 2-3 mm, the system contains air. It must be
expelled by heating the sensor. If the piston can
be depressed without a tendency to return to its
original position, the system is leaking and the
thermostat must be repaired.
On assembling the remaining parts on a type
V8 thermostat, check that guide pin (25) on the
cylinder head (26) fits correctly into the groove
in the supporting tube (20).
Lubricate the thread with grease. After topping
up with fluid and reassembling the unit, adjust
the thermostat as described above.
Manual Safety Device
If the fluid system is defective, the handle (28)
can be used as a temporary means to control the
regulating valve. The handle is turned towards the
valve until the valve spindle is contacted.
Leak at the valve
If the medium leaks from the valve, it is rec-
ommended that the stuffing box (1) should be
renewed.
Close the stop valves if any, and unscrew the
handle (28) until there is no doubt that the valve
is open (reverse acting valve closed). Slacken
screws (17). Remove supporting tube (20). The
stuffing box is now accessible.
Repair of valves
Dismantle the thermostat and the valve. Remove
dirt or other foreign materials. If necessary, regrind
valve seat and cone.
Locking of the temperature setting on the
V8-temperature regulator
Extra equipment (Fig. 1 a)
a) Turn handle (28) to highest scale tempera-
ture.
b) Remove the screws (17) and slide off sup-
porting tube (20).
c) Set locking device (34) on supporting tube
(20).
d) Reset the supporting tube (20) on the stuff-
ing box (1) with screws (17).
e) With the locking device (34) pulled in direc-
tion of the valve set the temperature wanted.
f) Reset locking device (34) as shown, and
lock with screws (35).
Duostats
The column II of Fig. 2 indicates the sensor
proportion Vs / Vp.
The setting dimensions for duostat type V4.05
are independent of the sensor proportion - see
table.
As to the duostat type V4.10 the setting dimen-
sions for sensor proportion "L": differ from the
rest.
For further information regarding sensor propor-
tion please see Duostat leaflet.
