INSTALLATION
START-UP PROCEDURE
(HEATING ONLY)
The following conditions must be met prior to unit start-up.
Debris from soldering and/or other installation activities
can cause equipment failure. Ensure that all associated
lines and appurtenances are free of debris.
Check to ensure that unit is secure.
Check that blower wheel rotates freely within the
scroll housing.
Check all wiring to ensure that connections are tight.
Check all ductwork and pipe connections to ensure
proper seal.
Check to ensure that all packaging wraps are removed
from equipment.
Ensure that front access doors are properly installed.
Check to ensure proper connection(s) to the appropriate
blower speed tap. To do this, reference page 25 thru 29 and
select the correct model and desired fan speed data. Refer
to Figure 13 for appropriate motor tap/wire colour to use.
Perform all safety and start-up checks for Tankless Water
Heater as per manufacturer’s instructions.
Having verified all preceding checks, the Air Handler’s
Start-Up Procedure is as follows:
STEP 1: Purge and fill system; follow appropriate purging
procedure as laid out in this manual in section
titled “Purging and Priming the System”.
STEP 2: Turn on power supply to Air Handler. Caution:
blower and/or circulator may start to operate
if thermostat is on and a call is present.
STEP 3: Turn thermostat on and switch system to the
heating mode. The thermostat shall be set higher
than the actual room temperature; this will
cause the circulator to energize and initiate
the heating cycle. (If the pump does not start,
or the Air Handler is not producing heat, refer to
the Troubleshooting Section in this manual).
STEP 4: Program room thermostat as desired by
homeowner.
START-UP PROCEDURE
