Pre-Startup Checklist
Please review and ensure the following checklist is
complete and veried BEFORE starting up your heat
pump’s compressor for the rst time.
CAUTION
Heat pump startups may only occur with a factory autho-
rized commissioning agent. Do not start the heat pump
before the authorized agent is on site and ready to assist.
Placement and Physical Checks
F Unit is level, stable, and securely mounted.
F Unit has all appropriate service clearances,
and access panels are not obstructed by pipes,
wires, or other obstacles.
F Unit is adequately protected from falling objects,
vehicles, or other potential damage.
F Fans are securely mounted and wired to the unit.
F Loosen nuts on the compressor feet to remove
the slotted washers, and leave the nuts loose.
F Open the heat pump and inspect the cabinet around
the refrigeration piping and compressor for any
signs of leaks or oil. If any signs of refrigerant leak
are present, DO NOT START THE UNIT. Leaks
need to be identied and xed, and refrigerant
charge weighed, before startup can occur safely.
F Perform a tug test on all wires in the electrical
enclosure, to ensure all wires remain rmly seat-
ed after shipping. Ensure all power feeds are
powered down for this testing.
CAUTION
Damage to the compressor due to startup with visible
leak indication is not covered by warranty.
Air and Ducting Checks
F Ducting, cowl, or plenums are secured to the
unit, sealed, and insulated as appropriate.
F Ducting, if present, is complete, insulated, and
connected to terminal grilles/louvers.
F Exterior louvers and connecting ductwork will
limit moisture intrusion, and drain in or out for
what moisture does intrude.
Water and Piping Checks
F Exterior water piping is insulated, freeze protect-
ed, pitched toward drain points.
F All water piping has been pressure tested and
veried leak free.
F All water piping has been lled with water and
actively purged of air.
F Pressure relief valves are piped to the oor,
drain, or reservoir as per local codes.
F Water quality has been determined to be ac-
ceptable for operation and potable use.
F Verify tank temperature probe, if present, is installed
10-12" minimum above cold water inlet in primary
storage tank, and has at least the minimum cycle
volume between it and the heat pump’s inlet pipe.
Condensate Management Checks
F Exterior condensate piping is insulated, freeze
protected, pitched toward drain points.
F Pour several gallons of water slowly into the
condensate pan, and verify the drain is clear
and operational.
F Condensate pump, if used, is plugged in and
operational.
Electrical Checks
F Main power and 120V power wires are securely
attached to the heat pump and active.
F All control and communication wires are se-
curely attached, and connected equipment is in
place and ready to operate.
F Verify remote outdoor air sensor (ducted sys-
tems only) is installed in a location without sig-
nicant heat gains from intermittent sources and
is near the heat pump intake air louver.
Final Checks
F All panels and enclosures are securely closed
and afxed.
F All ball valves in the piping systems are open,
including valves on expansion tanks, storage
tanks, condensate drains and swing tanks.
F Ensure that the Startup Procedure in the follow-
ing manual section is on hand for the commis-
sioning agent to ll out during startup. PDFs are
available for download through your manufac-
turer’s representative or using the QR Code in
the “Startup Procedure” portion of this manual.
F Turn on main and 120V power to allow the heat
pump to warm up. DO NOT engage any func-
tions on the control interface.
