Step 16 – Final Checks
NOTE: Before leaving the job site, be sure to do the
following:
1.) Ensure that all wiring and water connections are
secure.
2.) Make sure that the units filters are installed
properly and are clean.
3.) Securely fasten all panels / covers and ensure all
system fasteners are tight.
4.) Leave the Owner’s Manual with the customer.
Explain the system and thermostat operation.
5.) Discuss the importance of periodic maintenance
requirements outlined in the owner’s manual.
6.) Fill out the Initial Installation data sheet within this
installation manual.
7.) Be sure to talk to the customer about the general
maintenance, winterization procedure, and to watch
for potential intake airflow restrictions.
8.) Ensure the supply registers are diffused properly and
free of whistling.
9.) Ensure all duct work is sealed, insulated and secured
properly.
10.) Be sure the customer knows where to purchase
more water and air filters.
11.) Ensure the supply registers are defused away from
heavy traffic areas and not directly on the customer.
12.) Discuss any periodic preventive maintenance plans
your company may offer.
Post-Installation/Seasonal Start-Up Procedure
1.) Inspect the unit to make sure that all safety devices
and other parts are secure.
2.) Install new water filters (minimum of 30 micron).
3.) If needed vacuum out intake air plenum.
4.) Check the level of surfactant in the wetting system.
Top off the reservoir with Dawn or Palmolive
dishwashing detergent, if necessary.
5.) Install new air filters.
6.) Check that the units fan will free spin by turning by
hand.
7.) Turn on the supply water and verify there are no
leaks.
8.) Open the cooled air-supply (or conditioned air)
damper and/or remove any air blocks that were
used to winterize the air conditioner.
9.) Turn on the power.
10.) Set the thermostat to a low temperature to get a
cool call to start the unit. The water will begin to fill
the cooling system. The first fill will take about an
hour to completely wet the heat exchangers if the
temperature is about 75
0
F (24
0
C) outside, 4 hours or
longer if about 100
0
F (38
0
C) outside. If the
thermostat is not calling for cooling, the heat
exchangers may not fully saturate with water at this
point. The air conditioner will fully wet-out when the
thermostat calls for cooling. Please be aware that
the water will cycle off for 2 minutes and then turn
back on based on the outside temperature and
humidity and air flow rate.
If there is a lot of soap in the unit at start up it may
take a day get all the bubbles out and the
temperature to come down to normal operation.
NOTE: When the thermostat is turned “Off” the fan
may not come on again for 2 minutes to prevent
fan short cycling.
11.) Set the thermostat to the desired temperature.
Normal Operating Procedure
Set the thermostat to the desired temperature.
In cooling mode, the thermostat will control the fan and the
water supply. Outside air is drawn through the fan, filtered,
cooled, and then delivered to the building. The cooled air is
delivered via standard air distribution ductwork to the
structure.
If the unit is located in a high-dust or high-contaminant area,
examine the air filters at least monthly and replace as
necessary.
Note: Do not dry heat exchangers at night by running the
blower using only cool night air. Doing so on a daily basis
will allow mineral deposits to build-up and void the HMX
warranty.
