Incorrect copper pipe installation
Malfunctioning / defective valve, hose or manifold valve
To resolve, please proceed step-by-step:
-
Ensure stable room and bottle temperature of +20°C to + 30°C, ideal is when bottle
temperature is higher than air temperature
-
Make sure that bottle contains at least a double amount of required amount of refrigerant
-
Check t
he entire copper pipe installation and make sure it all complies this User’s manual
-
Check the functionality of valves, hoses and manifold valve
-
If all OK, you need to help the filling with a compressor ON. This is done by turning the power
supply to the unit on and actually turning the unit on into a dehumidification mode (i.e.
compressor on). This can be done only by an Android application. Please see section 11
UNIT
TEST – PAIRING
for more details. Please DO NOT RUN THE UNIT WITHOUT REQUIRED
AMOUNT OF REFRIGERANT.
j.
When the required amount of refrigerant has been filled into the system, first close
the valve at suction at compressor unit and remove the valve from compressor unit.
Please make sure you close the valve on bottle and ‘Lo’ knob on manifold valve.
k.
Put service valve caps back at both suction and discharge side service valves and
fasten them tight. Please note those suction and discharge valves are to be kept
open for the unit’s operation. Make sure all copper pipes are properly insulation
against external conditions to prevent condensation and water leakage and also
burnt.
l.
This completes the refrigerant work.
Please note that above flaring and refrigerant work must be performed correctly
with utmost care. Any non-compliance with above may and will likely lead into unit’s
malfunction, failure or damage. Such state means complete warranty void and
manufacturer, distributor or reseller cannot be taken responsible in such case for any
property or personal damage or loss.
Always use charging scales for refrigerant filling. Do
not use pressure as indicator of the correct
refrigerant amount.
