WIRING

 

 

 

 

 

IMPORTANT!

 

 

CAUTION

 

See product nameplate wiring.

 

 

 

Check that the voltage and the frequency of the electrical supply

 

When the unit is out of service, remember to arrange in good

 

time  for  the  entire  water  content  in  the  circuit  to  be  drained 
down.

 

 

IMPORTANT!

 

Mixing  the water with  glycol modifies the performance of the 
unit.

 

Pay  attention  to  the  safety  instructions  regarding  ethylene 
glycol which are printed on the container.

 

 

If the unit is not used during the winter period, the water contained in 
the system may freeze.

 

 

Draining  the  water  circuit  needs  to  be  undertaken  in  good  time. 
However,  if  the  operation  of  draining  the  system  is  felt  to  be  too 
laborious,  a  suitable  quantity  of  antifreeze  may  be  mixed  with  the 
water instead.

 

 

 

 

3.2.2 Electrical connections

 

 

 

 

CAUTION

 

correspond to 220-240V single phase at 50Hz; that the available 
power  is sufficient  for the running  the  equipment;  and that  the 
supply cables are of adequate section for the maximum current 
which will be required.

 

 

Make  sure  that  the  electrical  supply  system  complies  with 
current national safety regulations.

 

 

Electrical  connections  must  be  made  in  accordance  with  the 
wiring diagrams supplied with the machine. For connection to the 
electrical  supply  network,  use  double-insulated  flexible  cable, 
twin pole + earth, section 1.5mm

2   

type H05RN-F.

 

 

Pass  the  supply  cable  through  the  slot  beside  the  air filter.  Use 
the  cable  clamp  provided  on  the  inner  side  of  the  panel  to 
secure  the  supply  cable  and  the  connecting  cables, and  strip 
only the length of cable needed to go into the connector block.

 

If  the  unit  is  mounted  on  a  metal  surface,  earth  connections 
must  be  made  in  compliance  with  local  regulations.  If  the 
optional  extra  electric  heating  element  is  fitted,  a  separate 
power  supply  must  be  provided.  Use  double-  insulated  flexible 
cable, twin  pole  +  earth, section  2.5mm

2

, type H05RN-F.

 

 

IMPORTANT!

 

Electrical connection of the unit must be carried out by 
qualified personnel in compliance  with  the  regulations  in 
effect in the country where the unit is installed. The company 
shall not be held liable for damage to persons or property 
caused by incorrect electrical connection.

 

 

The  power  cord  type  designation  is  H05RN-R  or 
above/H07RN-F.

 

 

This appliance can be children aged from 8 years and above 
and  persons  with  reduced  physical,  sensory  or  mental 
capabilities or lack of experience and knowledge if they have 
been  given  supervision  or  instruction  concerning  use  of  the 
appliance in a safe way and understand the hazards involved. 
Children shall not play with the appliance. Cleaning and user 
maintenance  shall  not  be  made  by  children  without 
supervision.

 

 

The  appliance  shall  be  installed  in  accordance  with  national 
wiring regulations.

 

 

DANGER!

 

Always  install  a  general  automatic  switch  in  a  protected  area 
near  the  appliance  with  an  adequate  capacity  characteristic 
delayed curve with sufficient breaking power. There should be 
a  minimum  distance  of  3mm  between  the  contacts.  Earth 
connection  is  compulsory  by  law  to  ensure  user  safety  while 
the machine is in use.

 

3.2.3 Startup instructions

 

 

 

CAUTION

 

 

IMPORTANT!

 

Machine  commissioning  or  the  first  start  up  must  be  carried 
out  by  skilled  personnel  qualified  to  work  on  this  type  of 
product.

 

 

DANGER!

 

Before  starting  up,  make  sure  that  the  installation  and 
electrical  connections  have  been  carried  out  in  accordance 
with the instructions in this manual. Also make sure that there 
are  no  unauthorized  persons  in  the  vicinity  of  the  machine 
during these operations.

 

 

 

Pipeline system has been vacuumed before initial start the 

equipment

 

 

1    Remove the connecting pipe’s side cover panel by cross 

screwdriver.

 

2    Remove the bolts that showed at the figure by slotted screw 

driver. Start up the pump to circulate the pipeline water and 
vacuum air from the system until there have water flow out 
from bolt holes, and then tighten the bolts the system.

 

3  Shutdown the system that showed at the figure by slotted

 

screwed and replace the side cover panel.
