START-UP
TEST OPERATION
Perform test operation after completing gas leak
and electrical safety check.
Turn on electrical disconnect to outdoor unit.
Push the “ON/OFF” button on Remote
Controller to begin testing.
Push MODE button, select COOLING,
HEATING, FAN mode to confirm all functions.
SYSTEM CHECKS
Conceal refrigerant pipes where possible.
Make sure drain hose slopes downward along
entire length.
Ensure all refrigerant pipes and connections
are properly insulated.
Fasten pipes to outside wall, when possible.
Seal and weatherproof wall hole which the
interconnecting wires and refrigerant pipes
pass through.
INDOOR UNIT
Do all Remote controller’s buttons function
properly?
Do the display panel lights work properly?
Does the swing louver function properly?
Does the drain work?
OUTDOOR UNIT
Push the mode button to COOL and adjust the
room setting to 61°F (16°C) deg. wait up to 3
minutes from compressor time guard. Does
compressor and outdoor fan turn on in cooling
mode?
Push the mode button to HEAT and adjust
the room setting to 85°F(30°C) deg. wait up to
3 minutes for compressor time guard. Does
compressor and outdoor fan turn on in heat
mode?
EVACUATION INSTRUCTIONS
Before using a manifold gauge and a vacuum
pump, read their operation manuals to make sure
you know how to use them properly.
Using a valve core removal tool with a micron
gauge port attach it to the low side valve
and remove the valve core. Then attach your
micron gauge to the appropriate port.
Connect the manifolds low side hose (blue) to
the other end of the valve core removal tool
Open the Low Pressure side of the manifold
gauge. Keep the High Pressure side closed.
Turn on the vacuum pump to evacuate the system.
Run the vacuum pump until your Micron Gauge
reads 400 microns
Isolate the valve core removal tool and watch if
the pressure rises: if it rises over 500 microns
keep running the vacuum. The goal is to stabilize
with no rise in pressure and stay at 500 microns
After you have achieved a proper vacuum
open the valves on the condenser using a
5 mm allen wrench turning them counter
clockwise until it stops
OPEN VALVE STEMS GENTLY
When opening the valve stems, turn the
hexagonal wrench until it hits against the stopper.
DO NOT try to force the valve to open further.
Replace the schrader valve back into the low
side service port. You are now finished with a
proper vacuum and you can remove your hoses.
Tighten valve caps by hand, then tighten it
completely using an adjustable wrench.
