5. Filling and Startup
Before turning on the unit for the first time, follow this procedure:
a) refer to front panel drawing and use fitting supplied.
Attach
3
/8" dia. hose with funnel and fill through fitting
marked fill/drain
b) fill reservoir with DI water
c) check all hose fittings for tightness. All external hose
connections are to be made with
1
/2" ID tubing or its
equivalent
d) Open door on front panel to be sure filter is in place
e) Turn on power with the circuit breaker on front of elec-
tronics cabinet. The green indicator light marked POWER
ON on front panel should now be activated. Keep in mind
that the warm-up period will vary depending on fre-
quency of use. The longer the laser is not operating the
longer the warm-up period will be.
The following are set at the factory and should NOT be adjusted by user:
f) the heater thermostat
g) the operational temperature in the temperature regulator
valve.
6. Maintenance
The recirculating cooling system of the cooling group requires a mini-
mum of service. Normal checking of lines for tightness and leaks should
be carried out monthly. The cooling unit has a built-in DI filter. The filter
should be replaced every 6 months or when indicated by front panel
resistivity light. Order replacement filters from Continuum part no. 313-
0099. The cooling group should be checked once a year for loose connec-
tions, loose screws and fasteners. (See Maintenance section for instruc-
tions on changing the DI filter.) All service inquiries should be made to
Continuum.
