QUICK START CHECKLIST
4
All electrical connections should be weather tight.
All cabinet and electrical fasteners should be secure.
Shipping vibration can loosen these connections.
Make sure the control wiring does not chaff and a
grommet is installed.
PRESSURE TESTING AND LEAK CHECKING
Pressure test the line set to 400 PSI for a minimum of
15 minutes.
A bubble solution should be used as necessary. All
braze joints and TXV connections should be checked.
EVACUATION AND CHARGING OF SYSTEM
Both the vapor and liquid service valves should be open
and back-seated.
The entire system should be properly evacuated to at
least 500 microns. A triple evacuation is the preferred
method for a clean installation.
An R-410A INITIAL CHARGE should be weighed in as a
liquid
compressor compartment.
The FINAL CHARGE (if required) is to be weighed in
through the 1/4" charging port on the outside of the
Acadia outdoor unit while the system is operating.
The vapor service valve is high pressure
gas during heating operation and low pressure gas
during cooling operation.
(NOTE) The charging port ALWAYS reads the low pressure side
of the system. The 3/8” service valve port ALWAYS reads the
high pressure side of the system.
Charging operations should always be performed in the
heating mode. If the system must be charged in the
cooling mode, a return trip is required to check the
charge during heating season.
Total charge amount is dependent on the total linear
length of the liquid line, excluding any allowance for 90
degree elbows; see (Table 1, Appendix C).
SYSTEM STARTUP AND CHECKOUT
The access covers to the indoor air handler should be in
place to establish proper air flow across the indoor coil
while the system is operating.
After applying power, ensure the applied voltage is
within specifications. If the voltage is outside of
specifications, contact the local utility company.
Verify the Controller is active and no error conditions
are present.
Set the Controller program in the outdoor unit; P0 for
electric back up, P1 for dual fuel back up.
Obtain an accurate measurement of the outdoor air
temperature at the Acadia outdoor unit.
Measure the liquid line temperature by attaching and
insulating an accurate thermistor type or thermocouple
type as close to the Acadia
outdoor unit as possible.
Place the system into a 2
nd
Stage Heating Call (24VAC to
the Y2 terminal at the Acadia outdoor unit). A 5 minute
anti-short cycle timer will run out before any
compressor operation is permitted by the Controller.
Operate the system for a minimum of 30 minutes
before adjusting the charge.
Measure the liquid service valve pressure by attaching
an accurate R-410A rated gauge to the 3/8 service
valve port.
Refer to (Table 14, Appendix C) for the required sub-
cooling temperatures in the heating mode.
For every 1 lb of additional refrigerant added, allow
sufficient time for the system to settle before taking
another sub-cooling reading.
Fill in the service sticker on the electrical box cover
during installation.
IMPORTANT: Upon completion, be sure to do the following:
Ensure that all wiring and tubing is secure in the Acadia
outdoor unit before installing panels and/or covers.
Securely fasten all panels and/or covers and ensure all
fasteners will remain tight.
Tighten all access fitting caps to 1/12-turn past finger
tight.
Leave the nual with the owner and explain
the system operation and periodic maintenance
requirements outlined in the manual.
heck List with the new Acadia
owner.
Fill out the Dealer Installation Check List and place in a
customer file.
Fill out the Installation Data Sheet on the last page and
e-mail, fax, or mail it to Hallowell International (e-mail
address, fax #, and mailing address are available on the
front cover).
