Triangle Engineering of Arkansas AQ3613 - Manual (Page 5)

Cooling pads for this evaporative unit are cross-fluted with an intake and discharge
side. They are directional, and are clearly marked with arrows to show proper vertical
and horizontal installation.
When removing pads for maintenance, such as cleaning the interior of unit, always:
1. Disconnect all sources of electricity from unit.
2. Remove screws from metal guard located above pads.
3. Remove center pad first and then remaining pads.
4. When reinstalling pads, insert right and left pads in unit.
Center pad is inserted last.
With proper care, cooling pads will last 3 to 5 years. If unit is used on a daily basis, pads
should be dried each day. Drain sump and replenish with fresh water before reusing.
To Remove Water from Sump Area (Flushing)
1. Turn unit off.
2. Remove cap located below water intake hose .
3. Turn on pump. Pump will remove water from sump.
If purging water into a drain:
1. Connect hose to fitting where cap was removed.
2. Remove center pad to access shutoff valve on spray bar.
3. Turn valve to "OFF" position.
4. Turn on pump and pressure will be diverted to drain hose.
5. When water is completely removed, turn shut-off valve to "ON" position.
Pads should be fully dried every 24 hours during periods of continuous use. This will
discourage growth of algae. Watch for dry streaks on intake side of pads. If they are
observed, disconnect from electrical source, remove pads and spray bar and disassemble.
Clean spray bar and properly reinstall. Reassemble unit and check for proper water
distribution.
Proper water distribution is the single most important means of prolonging pad life. The
water will flush away dirt and contaminants which may be harmful to the pad. Areas
"starved" for water will be the first to clog or soften. Do not turn off water during
operation. Water flow must be maintained at a constant rate.
Evaporative cooling pads are designed to use a recommended quantity of water flow for
maximum performance. Your AQUACOOL cooling unit is built in accordance in these
standards. This water flow will provide a protective surface on the pad. Only a small
portion of the water will evaporate, the rest will serve to flush a clean pads during
operation.
