J) If your piping system is subject to impulse pressure resulting in a “water
hammer” condition, a surge tank or other means must be provided to remove
this condition; otherwise the extreme momentary pressure may rupture and
fracture the quartz sleeves.
K) Provide an electrical disconnect switch to the unit if it is not supplied with the
unit. During service and maintenance, the electrical power must be removed.
L) Operate the equipment /- 5% of 240vac.
M) Interface the Low UV, High Temperature, or Lamp Out Alert Alarm relays to
any system monitoring station.
N)
After installation of the quartz sleeves, always pressure test the system prior to
installation of the UV lamps and applying electrical power. All leaks should be
repaired.
During pressure testing, do not stand in a direct line with the quartz sleeves.
O) Before start-up, flush the UV unit and discharge piping to rinse out any debris
left from installation.
P) The UV treatment chamber should be filled with water. The flow of water
during the initial filling should not exceed 50 GPM.
Failure to comply may result
in quartz sleeve breakage.
Q) While the equipment is in normal operating mode, check to see that there is
airflow at the cooling fan intake and exhaust ports. Depending upon the
model, there are generally one or more exhausted fans that should be
cleaned and maintained. Some units have mesh filter, which should be
cleaned frequently, depending upon the operating environment.
Don’ts
A) Do not exceed maximum operating pressure of unit.
B) Do not exceed the maximum flow rate of the model.
C) To maintain standard rated performance, do not allow the inlet water
temperature to exceed 80
°
F (27
°
C). Units should not be operated with water
temperatures exceeding120
°
F (49
°
C).
For applications between 80
°
F (27
°
C) and
120
°
F (49
°
C), contact Aquafine

.
D) For heat sanitization it is recommended that stainless steel compression nuts
be used in place of CPVC compression nuts. The selection of the Elastomer
should be considered.
E) Never allow operating water temperature to exceed 120
°
F (49
°
C). Permanent
damage can be caused to the UV lamp(s), electronic ballast and related
components above this temperature. Operating the ultraviolet unit above the
defined temperature through the chamber automatically voids the warranty.
Elevated temperatures cause the UV lamp(s) to lose effectiveness. The heat
can permanently damage the ultraviolet lamp(s). The heat can also damage
the lamp ballast and related instrumentation.
F) Do not exceed 3 “ON/OFF” cycles per 24-hour operation. Excessive cycling of
the unit will prematurely age the UV lamps.
