Symptoms That Are Not Faults; Troubleshooting - Sinclair SDV5 Series User Manual

Maintenance after a long period of non-use
Check for and remove anything that might be blocking the inlet
and outlet vents of the indoor units and outdoor units.
Clean the unit casing and clean the filter. Refer to [Cleaning
the filter] and "Cleaning the filter" for instructions. Re-install
the filter before running the unit.
Turn on the power at least 12 hours before you want to use the
unit to ensure it works properly. As soon as the power is
turned on, the remote control display appears.

6. SYMPTOMS THAT ARE NOT FAULTS

The following symptoms may be experienced during the normal
operation of the unit and are not considered faults. Note: If you
are not sure whether a fault has occurred, contact your supplier
or service engineer immediately.
Symptom 1: The unit will not run
Symptom: When the ON/OFF button on the remote controller is
pressed, the unit does not immediately start running.
Cause: To protect certain system components, system start-up
or re-start is intentionally delayed for up to 12 minutes under
some operating conditions. If the OPERATION LED on the unit's
panel is lighting, the system is working normally and the unit will
start after the intentional delay is complete.
Heating mode is running when the following panel lights are on:
operation and the "DEF./FAN LED indicator (cooling and
heating type) or the fan only indicator (cooling only type)".
When it starts but the compressor does not, the indoor unit
activates protective measures because of the outlet
temperature.
Symptom 2: The unit emits white mist
White mist is generated and emitted when the unit starts to
operate in a very humid environment. This phenomenon will
stop once the humidity in the room is reduced to normal levels.
The unit occasionally emits white mist when it runs in heating
mode. This occurs when the system finishes periodic defrosting.
Moisture that may accumulate on the unit's heat exchanger coil
during defrosting becomes mist and is emitted from the unit.
.
Symptom 3: The unit emits sounds
A continuous sound (other than that made by the unit's fan) is
heard when the unit is running in cooling mode. This is caused
by the unit's drain pump (on units that have a drain pump).
A squeaking sound is heard when the unit stops after running in
heating mode. This is caused by plastic components cooling
down and contracting.
A slight hissing sound is heard when the unit is running. This is
the sound of refrigerant flowing through the unit and through the
piping that connects the unit to the rest of the system. This sound
is more noticeable when the unit starts/stops running and the
flow of refrigerant begins/ceases.
Symptom 4: Dust is emitted from the unit
This can occur when the unit first runs after a long idle period.
Symptom 5: The unit gives off a strange odor
If smells such as those of strong-smelling food or tobacco smoke
are present in the room, they can enter the unit, leave trace
deposits on the unit's internal components, and later be emitted
from the unit.

TROUBLESHOOTING

7.1 General
Sections 7.2 and 7.3 describe some initial troubleshooting steps
that can be taken when an error occurs. If these steps do not
resolve the issue, arrange for a professional technician to investi-
gate the problem. Do not attempt further investigations or trouble-
shooting yourself.
If any of the following errors occur, power the unit off, contact a
professional technician immediately and do not attempt trouble-
shooting yourself:
- A safety device such as a fuse or circuit breaker frequently
blows/trips.
- An object or water enters the unit.
- Water is leaking from the unit.
