QUI-QSMSPAL-002
Basic Mini Split Applications
• Computer or Data Rooms
• Commercial Spaces e.g. Offices, Shops,
Churches and Eating/Drinking
establishments
• Residential
• All 3 have different rules of thumb when it comes
to sizing and also the accessories needed for
proper operation, but the general rule of SIZE
THE UNIT TO THE ROOM must be used. For
specific applications always use a Manual J
Computer/Data Rooms
• Basic Rule of thumb
Sizing :
250 to 275 sqft per
12,000 Btu/h
• 24/7 operation 365 Days
a year
• MUST install an ICM low
ambient controller and a
crankcase heater
• Must keep Air Filters
clean as the unit could
freeze up if the filters are
not cleaned monthly
Commercial Installations
• Basic Rule of Thumb
Sizing :
400 to 450 sqft per 12,000
Btu/h
• May be in cooling
operation 365 Days a year
• If this is the case we
MUST install an ICM low
ambient controller and a
crankcase heater
• Make sure line set lengths
are kept below the
maximum line set length
stated
Residential Installations
• Basic Rule of Thumb Sizing :
550 to 600 sqft per 12,000
Btu/h
• Keep the Indoor unit a
minimum of 4ft from the floor
with no obstacles within 15ft in
front of the unit for the 9/12k
and 25ft for the 18/24k units
• Master Bedrooms to save
energy or have a different
temperature
• FROG’s or Bonus Rooms
where ductwork can’t reach
Installation and Operation
Requirements before Installation
• Correctly sized Indoor/Outdoor Units, they must
be a matched pair
• Correctly sized breaker/disconnect
• Line set, with both pipes insulated
• Electrical Interconnect wire – must be a
minimum of 14 AWG
• 5/16” Gauge adaptor for R410A gauges
• Small Electrical screwdriver for terminal
connections
• Low Ambient Control and crankcase heater if the
application requires cooling below 65 DegF
• Reading the Installation and Operation manual
Locating Indoor Unit
• Install Indoor unit so it can deliver air into the
room and return it to the unit, no obstacles to
airflow within 10ft of the unit
• Must be a minimum of 5ft from the floor
DO NOT THINK OF THIS AS A PTAC
• If installing multiple units allow a minimum of
15ft on center between Indoor units on the
same wall
Indoor Unit Installation
Remove the plate from the rear of the unit, it is held on by a Philips head screw
Mount the plate on the wall, make sure the plate is level, bend the mounting tabs
out slightly to ease unit mounting
Using the Templates provide, locate and drill a Ø3” hole at an angle of 5°
downward towards the outside of the building to allow the line set and condensate
hose to reach the outside
Indoor Unit Installation
Rotate the pipes and tape the condensate hose to the pipe – hose must be at the
bottom – I like to also add the interconnect wiring at this point to save time and
effort trying to thread the wire through the wall hole with the unit in place
If a Romex connection for electrical is required to satisfy local codes a ½”
connector is provided on the rear of the unit
On Heat Pump units the condenser coil sensor must be connected to the Outdoor
unit so run that along with the refrigerant piping and interconnect wiring
With Indoor unit mounted
• The refrigerant pipes can
now be carefully bent to
the required angle –
Suction line has
corrugations to prevent
kinking
• Condensate hose can be
run to outside or to
building drain – always
use rigid piping
Connection from unit fits
a ¾” OD, 5/8” ID Vinyl
PVC hose perfectly
Install the Outdoor unit
• Ensure unit is not
exposed to high winds –
possible wind baffle
required
• Raise Heat Pump units at
least 4” from ground or
pad to help draining
during defrost
• Outdoor unit provides
power for Indoor unit so a
local disconnect will be
required

DO NOT UPSIZE LINE SETS
BOTH LINES MUST BE INSULATED
NO FILTER DRIERS OR SIGHT GLASSES
Line Set Connections
• Keep both ends of the
line set sealed until it is
time to connect
• Flare connections at both
units – we do not
recommend brazing
• Adding a little vacuum
pump oil on flare nut
threads helps get them
started
• Always use 2 wrenches
to prevent kinking
• Currently units are not
supplied with flare nuts
unless our line sets are
used
Leak Test & Evacuation
• Gauge connections on the Schrader's are
5/16” not ¼” to prevent confusion – Adaptors
Yellow Jacket # 19173 are required
• Once line set is connected at both ends leak
check with dry nitrogen
• Do not let line set sit open to atmosphere place
on vacuum ASAP
• Vacuum down to a minimum of 200 microns to
ensure all moisture is removed
• Double evacuation, with a break using dry
Nitrogen is recommended for full system
cleanliness
Refrigerant Charging
• Always open Suction
valve first – uses a 6mm
Hex wrench, then open
“Liquid” valve with a 5mm
Hex wrench
• Doing this can prevent
the Cap Tube, located
behind the “liquid” line
service valve becoming
oil logged, putting the unit
into a vacuum on initial
start up
Refrigerant Charging
Units are charged for line sets of 25ft as standard

• Tip – To connect the whip liquid
tight connection take the bottom
plate off first and connect it off the
unit
Electrical Stage II
• Outdoor unit MUST provide
power for the Indoor unit
• Either L1 or L3 ON THE
OUTDOOR UNIT MUST BE
WIRED TO L1 or L3 ON THE
INDOOR UNIT
• Either N1 or L4 ON THE
OUTDOOR UNIT MUST BE
WIRED TO N1 or L4 ON THE
INDOOR UNIT
• Polarity is EXTREMELY
important with these units
Electrical Stage III
• If unit is a Heat Pump don’t
forget to connect the Defrost
Sensor between the Indoor
and Outdoor units
(Extend with 18AWG if
necessary, 25ft of wire is
provided)
• To locate connector inside the
Outdoor unit will require
removal of top panel
• Unit will not operate in Heat
Pump mode without this wire
being connected – will show
an error code – 7 Blinks
Installing Low Ambient controls
• Low Ambient Control
ICM326H
• Crankcase Heater
(Mars or Raychem) –
wire this directly to
the line voltage
connections – 115V
for QSCE/HE 09/12
and 208/230V for
QSCE/HE 18/24
Installing the ICM 326H
• Fan Motor is Ball Bearing

Data Room or do you still want
Cooling below 32 DegF?
• Wind Baffles
• Make your own, using our
specifications and
dimensions
• Install both on Front and
Rear of condensing unit
for those windy locations
and extreme cold
• Allows Cooling operation
down to 0 DegF
Unit Start up
• On initial power up of the unit, it will immediately start
the Outdoor unit in the cooling mode
Do not power the system until it is ready to be started
• Use the remote control to put the unit into the required
modes to test operation
• In Heat Pump mode the Indoor fan will run for 12
seconds to sense air temperature and then stop until
Indoor coil temperature reaches 98 DegF
• 3 Minute Anti Short Cycle Timer built into the system,
along with Auto restart after a power failure
Control Modes
• Auto, Cool, Heat, Dry and Fan Modes
• Unit has a 24hr clock for the timer function, this
allows a SINGLE event (On/Off) to be
programmed for a certain time, for repeating
events unit must be reprogrammed – Note
12pm/am actually is 0 hour
• 3 minute time delay between compressor starts
unless the unit is shut down, then the unit will start
immediately
Control Modes
• Auto, Cool, Heat, Dry and Fan Modes
• Auto – Basic set temp is 74 DegF, unit chooses
mode and fan speed based on room temp
• Cool – User set temp & fan speed, unit controls to
-2 DegF from room temp
• Heat - User set temp & fan speed, unit controls to
+ 2 DegF on room temp
• Dry – User set temp, fan speed unit set to low
• Fan – Fan operation only, user sets fan speed, no
cooling or heating function
Std Operating Pressures/Temps
• Cooling Mode (80/67 & 95°F)
• QSCE/QSHE 09/12/18/24
Suction Psig : 115psig = 37°F
Superheat : 8°F
Indoor Temp Split 30-35°F
• Heating Mode (70°F & 47°F)
• QSCE/QSHE 09/12/18/24
Liquid Psig : 400psig = 117°F

Troubleshooting
Indoor unit has 5 Troubleshooting codes and 2
operational codes
• Blinking once :
Initial start up in H/P mode
• Blinking Twice :
Room Temp Sensor failure
• Blinking 3 times :
Coil Temp Sensor failure
• Blinking 4 times :
Outdoor unit error
• Blinking 5 times :
Freeze protection
• Blinking 7 times :
Outdoor sensor failure/not
connected (Heat Pump only)
• Constant Blinking : Defrosting
Fault codes in detail
• Initial start up in H/P mode – Indoor coil
temperature has not reached 98 DegF when first
started in the Heat Pump mode
• Room Temp Sensor failure – Unit cannot read
the resistance of the Room temperature sensor
Check the sensor connections and resistance
60 DegF = 7,000Ω
70 DegF = 5,700Ω
80 DegF = 4,700Ω
Fault codes in detail
• Indoor Coil Temp Sensor failure – Unit cannot read the
resistance of the Room temperature sensor
Check the sensor connections and resistance
30 DegF = 14,000Ω
40 DegF = 11,000Ω
50 DegF = 8,800Ω
• Outdoor unit error – After the compressor has been
running for a period of 5 minutes, if the Indoor coil
temperature does not show the expected change in
temperature, in cooling the temp should be below 77
DegF, in Heating coil temp should be above 86 DegF
Check compressor operation, refrigerant flow
Fault codes in detail
• Freeze Protection – If the Indoor coil temperature is
below 32 DegF after 10 minutes of compressor operation
or is below 5 DegF after 5 minutes of compressor
operation the unit will shut down
Check refrigerant charge, filter condition, Indoor airflow
• Defrost Sensor Error – Heat Pump units must have the
Defrost sensor connected between the Outdoor and
Indoor units, otherwise it will not operate in Heat Pump
mode
Unit will run in Cooling mode but will immediately error out
if switched into heating
Check the sensor resistance and connections between the
units
Fault codes in detail
• Defrost – Defrost operation is based on a combination of several
factors
If the Compressor has been running for 45 minutes total, Outdoor coil
temperature is below 23 DegF for at least 1 minute and the
compressor has been on for 3 minutes continuously the unit will enter
defrost
If the Unit has been in operation for 30 minutes before being turned
into Heat Pump mode it will enter defrost
If the Outdoor coil temp is below 28 DegF when the unit is turned on in
Heat Pump mode it will enter defrost
A defrost cycle will last a maximum of 8 minutes or the time taken for
the Outdoor coil to reach a temperature of 59 DegF
Other Troubleshooting
• Voltages can be measured from either L1, N1 or
L3, L4 to 1, 2, and 3 to determine if compressor,
Outdoor Fan and Reversing Valve are being
called for
• Check for the signal at both the Indoor and
Outdoor units
Other Troubleshooting
No Heat Pump Heating
Check that the unit is actually in the Heat
Pump Mode Sun = Heat Pump
What looks like a Flame is actually a drip,
putting the unit in de-humidification mode
which is cooling with a low fan speed
Check output for the 4 way valve energized
for heating will default into the cooling mode,
line voltage at #2 terminal, follow down to the
solenoid coil
Troubleshooting during operation
No PCB Output
Check for line voltage at Power terminals
Remove interconnecting wires, check for outputs
in cooling in heating mode
Check terminals, down to ground?
Check for operation lights on the units
Check fuse on PCB – 6.3A @ 250V, Radio
Shack #270-1068
Check molex plug connections on PCB
Check PCB receives signal from remote
