The elicitation way of connecting pipe, due to the installation site have left behind elicitation, right
behind elicitation,
After elicitation, connect hoses to cover on !he insulation sleeve, in the position which is about
10mm inside the cabinet, start the pack up for pipeline, until to the joint of hosepipe, the remaining
should be done after the joint connection finished.
After completion of !he above, you can hang the chiller on the baseboard and make the connecting
pipe through the hole in the wall.
3. Electrical controls and connections
1. Must strictly follow the wiring diagram. Non-sharing of two and more than two chillers of
a speed control switch or a thermostat.
2. After inslallation should be carefully checked before the first run whether the wiring is correct,
the ground is reliable.
Electrical construction must be done by qualified professional and technical
personnel; you should set air-conditioning independent connection fixed
line. The fixed-line connections mus! be equipped with more than 3mm
away from the contacts to open very wide disconnect device. Power lines
and cables should be used of specialized cables, for installation or
replacement, must be specified by the manufacturers of professional and
technical personnel to operate, users shall no! operate by himself.
The earth leakage protective device, power switch and circuil breaker must
be inslalled in the power, otherwise it will cause electric shock.
Caution
Must be grounded connection, if not properly grounded, may cause electric
shock.
The power cord must use GB5023 stipulated 227IEC53 (RVV) type or
equivalen! above electric wire, and fastened with wire fixtures, make
terminal not easily disconnect with external force. lmproper connection or
fastening cause tires. The connecting cable must use GB5013 slipulaled
Notice
245IEC57 (YZW)) type or equivalent above one.
Do not connect ground wire in !he gas pipes, water pipes, telephone lines or
a lightning rod and other products' ground line.
Please connect the power line to follow the connection circuit diagram
request.

4. System pressure test and water leakage
For fan coil air conditioning system, befo re the system pressure test, first should formulate
pressure-tested scheme, select the appropriate test pump, to formulate rational pressuretested
waterway. In testing process should be conscientiously record pressure-tested condilion, monitor
the system pressure changas al any lime, You should pay atlention to !he following poi nis when
formulating pressure-tested plan
(1 ) The exhaust valve on system piping line mus! be opened before adding water into coils, then
close !he valve after exhausting !he air inside coil.
(2) Water pressure test should be done on the temperatura conditions above 5ºC, otherwise
should take anti-freeze measures.
