Maintenance Recommendations
DVR Server cleaning is the practice of physically cleaning the interior, and exterior, of an DVR Server
including the removal of dust and debris from cooling fans, power supply, and hardware components.
Recommended maintenance frequency for i3 DVR units is once every 6 months.
5 Basic Maintenance Steps
Step 1: Swab Heavy Dust Areas
Heavy dust, grime and debris may accumulate on the DVR unit over time. Sweep the heavy dust and
debris off the unit. To loosen the grime, use foam rubber swabs. Do not use brushes, cotton swabs, or
cloth rags, as they can create static buildup and may leave residue. Never use fluid to clean the unit,
cleaning fluid or otherwise.
Step 2: Blow Out Accumulated Dust
Use proper ESD (Electrostatic Discharge) protection gear for this step, such as properly grounded wrist
strap and antistatic protective clothing and gloves. Do not touch hardware components inside the unit.
Remove the top lid of the DVR unit with the Phillips screw driver. Using the air canister nozzle, blow out
any accumulated dust thoroughly and from a variety of angles to remove all dust from the motherboard,
the sides of the expansion cards, the vents, fans and other hardware components. Apply canned air
evenly from all exposed sides of each hardware component to get into all hard-to-reach places and to
remove as much dust as possible. Apply canned air to the blades of the fan for several seconds to let it
spin and blow out the dust accumulated inside the fan. Apply canned air in-between hard drives (when
applicable), inside the optical drive and on all cable connections.
Step 3: Air Spray the Power Supply
Dust and grime that accumulate in the DVR Server’s power supply can seize it. Clean the power supply
by applying canned air through all the power supply’s vent openings. Do not open the power supply, as
it retains a powerful electrical charge even when turned OFF.
Step 4: Clean the Keyboard
Dust, hair, grime and grit accumulate inside your keyboard by falling in between the keys. Turn the
keyboard upside-down and apply canned air between the keyboard keys allowing all loose particles to
fall out. Sweep and discard any dislodged dust and other particles.
Step 5: Clean the Monitor
Clean your monitor with a screen cleaner that counters static buildup. Do not use household glass
cleaners on your monitor as it may cause permanent damage to the screen. Cleaning the screen makes
the image sharper, and removes the static charge that attracts dust, which might then find its way into
your DVR server.
