Ensure that you have a 2
nd
Stage call from the thermostat. Set the thermostat well above the indoor ambient and open doors
and windows if needed.
COOLING CHARGE CHECK PROCEDURE
1. The system is charged for heating performance. If the charge of refrigerant is in question, recover the system charge and weigh
in the appropriate charge according to the line set charging chart (Table 1, Appendix C).
2. If the system is installed as a new installation during the cooling season, a return trip to double check the charge amount during
heating season may be necessary.
Step 10 – Final Checks
IMPORTANT: Before leaving the job site, be sure to do the following:
1. Ensure that all wiring and tubing is secure in the system before adding panels and covers. Securely fasten all panels and/or cov-
ers and ensure all fasteners remain tight.
2. Tighten the service valve stem caps to 1/12-turn past finger tight.
3. Ensure the charge amount is written on the service sticker provided on the electrical box cover of the Acadia outdoor unit.
4. customer. Explain the system operation and periodic maintenance requirements outlined
in the manual. Leave the installation manual in the Acadia outdoor unit for future use.
5. Fill out the Dealer Installation Checklist and place in a customer file.
6. Be sure to talk to the customer about the general maintenance; shoveling around the Acadia outdoor unit and keeping it clear
of debris, basic thermostat use, and the importance of periodical filter changes.
7. Discourage the customer from setbacks of the thermostat program. High utility bills may result from a thermostat setback.
8. Talk to the customer about the defrost operation and how it will affect the register temperature.
9. Ensure the supply registers are diffused properly and away from heavy traffic areas and not directly on the customer and/or
seating areas.
10. Ensure the air handler has a proper air filter installed before you leave.
11. Be sure the customer knows where to purchase more air filters.
CARE AND MAINTENANCE
For continuous high performance and to minimize possible equipment failure, periodic maintenance must be performed on this
equipment. Frequency of maintenance may vary depending upon geographic areas, such as coastal applications. Pay close
attention to the cleanliness of the indoor and outdoor coils, proper air circulation, and duct sealing.
An example of a maintenance schedule would be changing the filter once every 1-3 months, an electrical inspection, and an annual
washing of the coils.
In coastal regions, the outdoor coil must be washed annually by a qualified service technician.
