• 

For  the  installation  of  the  differential  thermostat,  refer  the 
pro

ducer’s manual which is included in the package. 

• 

All of the units function with 230V / 50Hz. 

• 

In the case where an electric resistance is installed, the volt- 
age must be checked. The electric resistances up to 4kW are 
1~230  V  with  thermostat,  while  for  the  electric  resistances 
6kW  -  9kW  the  voltage  is  3~400V  and  the  installation  of  a 
thermostat is the 

installer’s obligation. 

• 

The  thermostat  once  installed  and  adjusted  functions 
automatically  on  the  boiler.  According  to  the  needs  of  the 
client,  the  temperature  of  the  water  can  be  adjusted  by  the 
installer  to  lower  or  higher  levels  from  the  original 
adjustment  and  between  30ºC  -  80ºC.  In  the  case  that  for 
some  reason  the  temperature  exceeds  the  tolerated  safety 
level,  the  safety  unit  is  activated.  This  is  adjusted  to  be 
activated  when  the  temperature  of  the  thermostat  reaches 
100ºC  (±10).  In  the  case  that  this  happens,  you  must 
determine  its  cause.  After  the  water  cools  down,  we  can 
reactivate it manually by pressing the red button. 

• During  the  transport  of  the  thermostats  and  during  the 

process of installation avoid the hitting / banging, dropping of 
the thermostats, because they can cause serious damage to 
the  thermostat  with  very  dangerous  consequences  to  its 
operation.  The  electric  installation  should  be  made  by  a 
licensed  electrician.  A  faulty  electric  connection  can  cause 
an  explosion of the boiler. 

• In  the  case  where  the  hot  water  consumption  needs  are 

during  periods  of  the  day  with  little  or  no  sunlight,  for 
instance after 17:00 or before 10:00 a.m., the use of a timer 
is  recommended.  This  will  automatically  activate  the 
electric  resistance  and  as  long  as  there  is  a  need  for  hot 
water. 

• All  the  connections  must  conform  with  the  regulations 

(electrical, plumbing, urbanism and others) that apply in your 
area. 

 

after  completing  the  installation  of  the  system,  clean  the 
area  where  you  have  worked  ,  fill  out  the  guarantee  and 
send it by registered post to Helioakmi S.a.

 

 

 

 

HELIOAKMI 

S.A. 

is 

not 

responsible  for  damages  to 
the  products  or  third  parties, 
which  arise  from  the  faulty 
installation of the unit.

 

The  technical  characteristics 
can  change  without  prior 
notification.

 

 

 

 

If  your  Solar  Collector  will  be  stagnant  in  the  sun  for  an 
extended  period  of  time,  you  should  cover  the  collector  to 
protect  against  overheating  and  damaging  the  collector  and 

Your  Solar  Hot  Water  System. A heat  dissipation  device  may 
be needed to protect against overheating 

 

 

Snow  and  wind  loads  are  a  significant  factor  for  structural 
planning.  European  norms  were  established,  albeit  without 
specifically  taking  solar  installations  into  account.  Wind  and 
snow  loads  affect  the  collectors  and  the  installation  system. 
Depending on the conditions and height of the installation site 
as  well  as  the  collector  inclination,  the  mechanical  loads  on 
the system  can  vary  considerably. Also  see  guidelines for  the 
planning of structural frameworks and standards EUROCODE 
1, (European guidelines for structural planning). With combined 
snow and wind loads the maximum strain for the solar collector 

is 1,000 N/m². Note that wind suction spikes may occur on roof 
Edges. 
It  is  mandatory  to  follow  best  practice  rules  for  static 
planning,  especially  related  to  snow  and  wind  loads. 
Different  codes  and  regulations  apply  in  different  countries 
and  regions.  In  case  of  doubt  and/or  in  absence  of  exact 
static  calculations  (not  recommended)  always  allow  for 
additional  fixtures,  weight,  anchors,  and  screws,  especially  in 
regions with known weather extremes. 

 

 

This  type  of  installation,  do  not  increase  the  risk  of  attracting 
lightning and there are no records of ever happened such inci- 
dent.  However  we  suggest  that  you  check  for  a  lightning  rod 
in  your  area  and  also  check  if  it  gives  protection  to  the  place 
of your system. If it exists, and if it is not enough, we suggest 
that you provide a lightning rod according to your country rules 

metallic parts (solar collectors, piping and support devices) to 
the  lightning  rod  installation  with  copper  cable  never  less  50

cross section. 

Note: the lightning protection must be done by qualified profes- 
sionals.
