PZN Aquamatic Water Heater
Doc Ref M107 issue 1.3 Sep 2018.
Warning: Do not install outside and in places
with an aggressive environment
.
Select the appropriate model on the basis of performance
data for average fan speed.
Example of vertical installation
Warning: To allow for proper air flow and
therefore the correct operation of the unit, it
is essential that there is no obstacle near the
outlet nozzle side panel.
Example of vertical installation
Note: When mounting the heater on the ceiling
it is recommended that you use the CEILING
INSTALLATION KIT.
Wiring external to the air heater must be installed in
accordance with the I.E.E. Regulations for Electrical
Installations and any local regulations which apply.
All standard heaters are supplied by 230V - 1ph, 50Hz.
The method of connection to the main electricity supply
must:-
- facilitate the complete electrical isolation of the unit(s)
via a suitable fused isolator (see section 2.4.5 for ratings)
- be in a readily accessible position adjacent to the unit(s)
- serve only the unit(s)
- have a contact separation of at least 3mm in all poles.
See the accompanying wiring diagram for the heater
electrical connections
The selection and installation of water system
components is the responsibility of the installer. The
installer must observe correct working practices and the
legislation in force at all times.
In systems filled with anti-freeze the use of water
disconnectors is compulsory.
Where the heater is supplied with special or recycled
water it must first be treated accordingly. Observe the
reference values in the table.
