• Remove spray distribution access panels, and inspect and clean the spray branch,
nozzles, and drift eliminators as necessary.
• Remove all dirt and debris from the fan guard(s).
• Open hinged access fan panel (see
Figure 4
) to clean all mechanical components and
to remove dirt and debris from plenum area.
• The installation and manufacturing processes used for field assembly of steel-piped
systems may leave weld byproducts inside the hCore® Heat Transfer Technology and
connecting piping. It is common practice to install filters and/or strainers that remove
contaminants during initial system operation. Shortly after system start-up, the filters
and/or strainers should be cleaned or replaced.
• Conduct external inspection of the equipment, sensors and probes. Check for leaks,
corrosion, and any structural damage.
• Conduct internal inspection of the equipment. Check for anything unusual such as
structural or mechanical component damage.
• Inspect wiring and connections for all the components.
• Confirm that wiring and connections inside of the iPilot® Control System panel are
secured.
• Inspect riser pipe(s) and connections.
• Inspect process fluid manifold piping and connections.
• Thoroughly inspect the fan(s) and pump(s) for any mechanical or physical damage.
• Verify that fan(s) rotates freely.
• Inspect solenoid valves, make-up valves, drain valves, and level switches.
• Check that the mechanical make-up valve is operating freely.
Pre Start-up Checks
• Verify that the following items are turned off and the unit is locked
out/ tagged out:
– Supply power disconnect
– Fan motor(s)
– Pump motors
– iPilot
®
Control System (control panel)
– Basin heater control panel (optional)
– Basin heaters (optional)
– Positive closure dampers (optional)
• Verify that all panels are closed and secure, including the following:
– Fan access panel
– Spray distribution access panel
– Basin access cover
– iPilot
®
Control System panel door
– Heater control panel door (if ordered)
• Verify the following water connections:
– Solenoid make-up valve –
Incoming water pressure must
be between 20 and 75 psig
– Drain valve
– Overflow
Figure 5.
Panels to Secure
DANGER:
Rotating equipment
will cause severe personal injury
or death to persons who come in
contact. Do not perform any service,
maintenance, or inspection on or
near the fans, motors, and drives,
or inside the unit without first
ensuring that the fans and pump
motors are disconnected, locked
