2.6.3 Electrical connection precaution
Warning
Installation of electric items must be carried out by qualified, professional technicians. An isolated circuitry
should be fixed with whole-pole disconnection devices, which is with at least 3mm gap of touch point. .
Power supply and indoor to outdoor connection should use special cable. Providing the necessity of
installation or replacement, the professional technician of service store appointed by manufacturer must
be required, while self-operation by users is prohibited.
Incase ofany electric shock accident, thecreepage protection devices /power supply on-off and breaker
mustberequired w i t h power supply.
Machine mustbeearthed surely.Ifnot, it’ll beprobably caused creepage.
T h e power cordshallconsist w i r e s of227IEC53(RVV) typespecified inGB5023 orthose ofequivalent
grades orabove .Secure thew i r e s w i t h fixtures, sothat theterminals will not easily dislodge under
external forces. Incorrect connection orfixing maycause afireorother hazards. T h e internal and external
connecting cableshallconsist w i r e s of245IEC57(YZW) typespecified inGB5013 orthose ofequivalent

nor totheearth line ofother devices.
Others
● P l e a s e connect thepower cordaccording totheinstructions ofthecircuit diagram.
●Securely and firmly connect thew i r e s totheterminal holder w i t h cablefixtures, toprevent theexternal
forces fromacting onthew i r e s and causing dangers.
2.6.4Commissioning
After installation, machine canb e started commissioning.
Checkinstallation condition
◇Checku n i t installation a n d w i r e connection i n accordance w i t h t h e requirement o f service manual.
◇Check t h e power supplying, diameter o f w i r e s , a i r on-off a n d makei t suret h a t t h e i t e m s canb e

Pressure Test a n d Water Filling o f Unit
Before conducting pressure t e s t o f f a n coila i r conditioner system, i t ’ s necessary t o formulate
pressure t e s t scheme a n d select appropriate pressure t e s t pump. Duringpressure test, i t ’ s necessary
t o carefully record p r e s s t e a t status timely monitor pressure change o f system.
Pay attention t o t h e following points when formulating pressure t e s t scheme:
Before filling w a t e r forcoil,vent v a l v e o n collecting head mustb e opened a n d t h e n closed until
exhausting t h e a i r i n coil.
Pressure t e s t should b e conducted under a i r temperature conditions above 5℃,otherwise,
anti-freezing measures should b e taken.
During hydraulic t e s t , increase pressure slowlya n d evenly. carefully check i f t h e r e i s w a t e r leakage a t
t h e jointafter w a t e r p u m p stopsrunning a n d hydraulic pressure stabilizes. Don’t repair i n case o f
hydraulic pressure.
As forwater filling i n t h e system,i t ’ s mandatory t o fill w a t e r b y layer, discharge b y layer a n d t e s t l a y e r
b y layer.
After confirming t h e r e i s n o leakage o n pipeline o f system,finally conduct thermal insulation treatment
according t o design scheme.
Pressure t e s t scheme o f systemshould b e formulated according t o t h e principle o f water-flowing from
l o w t o h i g h a n d injecting water layer b y layer. Moreover, t h e above points mustb e followed, otherwise,
structural damage may be caused to fan coil unit and system pipeline.
Initial Operation o f Unit
Before initial operation, clearforeign matters i n d r i p t r a y , fanshella n d around coil,and check i f
