3. Unit content
The SIL UV sterilisation unit is comprised of three
main components:
1. UV Lamp plus mounting clips and reflector.
2. Connecting cable, plug and protective boot.
3. Control Ballast.
Note:
Depending on the installation; the ballast
may be supplied:
a. Loose; for fitting inside the control panel
OR
b. Installed either singly or in multiples within a
sealed aluminium enclosure.
OR
c. Within a separate control panel. The control
panel may provide optional extra features such
as ON/OFF control, BMS connectivity, run-time
counter and lamp failure indication depending
on the unit specification.
d. Optional installation fixtures are also available to
order for fitting the UV lamp assembly inside the
AHU.
N.B. Installation:
In every case the unit should
be installed by suitably qualified and trained
personnel.
The Germicidal UV Lamp and reflector should be
installed so that the lamp is facing the coil.
Lamps may be installed either Upstream or
Downstream of the coil depending on the available
space and orientation of the equipment. Lamps
should be positioned as indicated on the drawing
provided by SPC.
Ideally the coil should be mounted 10-12 inches
from the face of the coil. Do not mount the lamp
closer than 4’’ (100 mm) from the coil face.
After Installing the lamp fitting, insert the lamp into
the clips provided. Connect the 4-pin socket to the
pins at one end of the lamp and push the boot
around the end of the lamp.
N.B:
Do not touch the UV lamp without gloves.
Always clean the lamp surface with a dry cloth
after installation.
Connect the lamp cable to the control ballast using
the connector provided.
Turn off all power to the unit before connecting
the ballast box to a fused and switched 220-240v
power supply. This supply must be broken by a
micro-switch (by others) on the AHU access door.
Warning Labels:
to be fixed outside of the AHU
