SAFETY CONSIDERATIONS AND INSTALLATION RECOMMENDATIONS
6
Avoid direct copper tubing contact with duct work, floors and floor joists, walls and wall studs, water pipes, or other
construction materials such as brick and concrete block.
Do not suspend the refrigerant tubing from joists and/or studs with rigid wire, strap, or other hangers which may come in direct
contact with the tubing.
When necessary, use hanger straps which are large enough to fit around the tubing insulation and isolate the hanger straps
from the insulation by using metal sleeves bent to conform to the shape of the insulation.
If the line set is routed on the exterior of the home, be sure to add additional insulation to both the liquid and vapor lines to
minimize thermal losses from the line set. ncies. A maximum of 5 to 10
(NOTE) Exterior line sets may have high thermal losses that can reduce the system capacity and efficiency.
Ensure that the tubing insulation is pliable, sealed with tape or glue, and completely surrounds the Vapor and Liquid lines
separately.
Maximum recommended line set length is 50-ft. (15.24-m.); consult Hallowell International Technical Support if other.
Maximum recommended vertical rise of 10-ft. or (3.04-m.); consult Hallowell International Technical Support if other.
Mount the Acadia outdoor unit on a solid, level, foundation pad with a proper sub-base and proper drainage to ensure the unit
will not shift during its lifetime.
If the Acadia system is replacing an existing R-22 based heat pump or air conditioner, all piping must be replaced at the time of
the new installation. Mineral oil used in R-22 systems is incompatible with the POE oil used in R-410A systems like the Acadia.
Consult Hallowell International Technical Support with any questions.
IMPORTANT: The maximum liquid- O.D. for all applications. The 3/8 liquid line must be insulated independently
from the vapor line insulation.
(CAUTION) USE ONLY R-410A RATED SERVICE EQUIPMENT.
(NOTE) Only install the factory-supplied heat pump (bi-flow) liquid line filter drier on the liquid line at the indoor air handler
unit. Installation of the filter drier inside is to help prevent heat loss during heating operation. The filter drier must be insulated.
Obtain replacement bi-directional R-410A rated filter driers from your local supply distributor.
