Unit Start Up - Water Furnace SAH Series Installation Manual

Unit Start Up

• Check that supply voltage matches nameplate data.
• Fuses, breakers and wire size are correct.
• Confirm that the 15kW or 20kW auxiliary heat kit
is wired correctly (see "Electrical Data" section if
applicable).
• Low voltage wiring is complete.
• Piping is complete and water system is cleaned
and flushed.
• Air is purged from the closed loop system.
• Isolation valves are open, water control valves or pumps
are wired.
• Condensate line is open and correctly pitched.
• Transformer switched to 208v if applicable.
• DIP switches are set correctly.
• Blower rotates freely.
• Blower speed is correct.
• Air filter/cleaner is clean and in position.
• Service/access panels are in place.
• Return air temperature is between 50-80°F heating and
60-95° cooling.
• Check air coil cleanliness to insure optimum performance.
Clean as needed according to maintenance guidelines.
To obtain maximum performance the air coil should be
cleaned before startup. A 10 percent solution of
dishwasher detergent and water is recommended for
both sides of coil. A thorough water rinse should follow.
Maintenance Filters
Filters must be clean to obtain maximum performance.
They should be inspected monthly under normal operating
conditions and be replaced when necessary. Units should
never be operated without a filter. Always replace the filter
with the same type as originally furnished.
Condensate Drain
In areas where airborne bacteria produce slime in the drain
pan, it may be necessary to treat chemically to minimize
the problem. The condensate drain can pick up lint and dirt,
especially with dirty filters.
Blower Motors
The ECM motors are equipped with sealed ball bearings and
requires no periodic lubrication.
Air Coil
The air coil must be cleaned to obtain maximum perfor-
mance. Check once a year under normal operating condi-
tions and, if dirty, brush or vacuum clean. Care must be
taken not to damage the aluminum fins while cleaning.
Caution: Fin edges are sharp.
SAH AIR HANDLER INSTALLATION MANUAL
Ethernet Cable
A 100 foot Cat6 Ethernet cable is shipped with the air han-
dler in the 985506-01 SAH Installation Kit. This cable can be
plugged into the backside of the Ethernet port located on
the top panel of the air handler. The cable then can be rout-
ed and connected into the AID Tool port on the compressor
section. The installer will then be able to plug the AID Tool
into the Ethernet port on the air handler giving him control
of the compressor section. If the compressor section is con-
nected to Symphony, the Ethernet cable would connect to
the AID Tool port on the back of the Symphony router. If the
installer was using the AID Tool and the compressor section
equipped with Symphony, the Ethernet cable from the air
handler would need to be unplugged, and replaced with the
AID Tool cable. The maximum Cat6 cable length should be
kept to 150ft or less.
Powering The Controls For Control
Option C
Initial Configuration of the Unit
Before operating the unit, apply power and complete the
following Aurora Startup procedure for the controls con-
figuration. An AID Tool is recommended for setup, con-
figuration and troubleshooting, especially with an Aurora
'Advanced' Control. AID Tool version 2.06 or greater is
necessary for AHB setup.
1. Confirm that Dipswitch 1 on SW1 on the AHB board is
set in the OFF position.
2. Configure Aurora Screen
a. In advanced controls - Confirm AHB is added and
communicating.
b, In advanced controls - If using a communicating
thermostat confirm the communicating thermostat is added
and communicating. Set thermostat mode to off.
c. In advanced controls - Confirm IntelliZone2, if in-
stalled, is added and communicating. Set Zoning system to
off mode.
3. Aurora Setup Screen
a. ECM Setup for Heating Airflow - select "G", low, high
and aux blower speeds as appropriate for the unit and elec-
tric heat.
b. Cooling Airflow % - sets the cooling airflow % from
heating airflow. Factory setting is -15%.
See Compressor Section installation manual for more con-
trol instructions.
