3.4 Tips
To prevent damage to the internal parts of the dryer and air com-
pressor, avoid installations where the surrounding air contains
solid and/or gaseous pollutants (e.g. sulphur, ammonia, chlorine
and installations in marine environments).
3.5 Electrical connection
Use approved cable in conformity with the local laws and regula-
tions (for minimum cable section, see par. 8.3). Use copper con-
ductors only, rated for a temperature of at least 140˚F(60˚C).
If the dryer is connected to a circuit protected by fuses, u se time
delay fuses marked “D”.
Connect the 3 cable phases to terminals L1---L2---L3 for
SRL-- 1200 --- SRL -- 1600, terminals T1---T2---T3 for SRL-- 2000
--- S R L -- 6000 of the disconnecting switchand the ground wireto
the green screw or bolt identified by the label “GR”. Install a dif-
ferential thermal magnetic circuit breaker with contact opening
distance of 0.12 inches (3 mm) ahead of the system (IDn = 0.3A)
(see the relevant current local regulations).
3.6 Condensate drain connection
Y Make the connection to the draining system, avoiding con-
nection in a closed circuit shared by other pressurized discharge
lines. Check the correct flow of condensate discharges. Dispose
of all the condensate in conformity with current local environ-
mental regulations.
4 Commissioning
4.1 Preliminary checks
Before starting the dryer, make sure:
a) installationwas carried out according that given in thesection
3;
b) the air inlet valves are closed and that there is no air flow
through the dryer;
c) the power supply is correct;
d) with Wc version, open the cooling water circuit a few minutes
before starting the dryer.
4.2 Starting
a) Start the dryer before the air compressor;
b) switch the power on by turning the MAIN SWITCH
& to
“I ON”: the POWER LED (2) lights up turning yellow;
c) press
x: the POWER LED (2) turns green and the com-
pressor switches on; the dew point is displayed.
Y Scroll Compressor: if connected with the wrong phase se-
quence it turns in th e opposite direction, with the risk of being
damaged (in this case it is very noisy); immediately invert the
phases.
Y Fans (Ac version): if connected with the wrong phase se-
quence they turn in the opposite direction, with the risk of being
damaged (in this case the air exits the dryer cabinet from the con-
denser grilles instead from the fan grille --- see par. 8.6 and 8.7 for
correct air flow); immediately invert two phases.
d) Wait 5 minutes, then slowly open the air inlet valve;
e) slowly open the air outlet valve: the dryer is now drying.
4.3 Operation
a) Leave the dryer on during the entire period the air compres-
sor is working;
b) the dryeroperates inautomatic mode,thereforefield settings
are not required;
c) in the event of unforeseen excess air flows, by---pass to avoid
overloading the dryer;
d) avoid air inlet temperature fluctuations.
4.4 Stop
a) stop the dryer 2 minutes after the air compressor stops or in
any case after interruption of the air flow;
b) make sure compressed air does not enter the dryer when the
dryer is disconnected or if an alarm occurs.
c) P ress
x: the POWER LED (2) turns yellow again;
d) Turn the MAIN SWITCH
& to “O OFF” to switch the
power off.
Y Wc version, close the water circuit with the dryer stopped.
