1. Appropriation and characteristic
Flow water heaters type PERFECT 350, 400, 450, 500 ELECTRONIC are desig ed for delivery of
warm water to sa itary equipme t such as si ks, wash-bowls used at bath-rooms, work-shops
lavatories, etc. Heaters are equipped with electro ic co trol systems which elimi ate the most
deceptive parts as membra es, electric co tacts used i traditio al devices of such ki d. This
system substa tially prolo g heaters work life a d reliability. Additio ally, applicatio of electro ic
air-pluggi g se sor i creased heaters resista ce agai st serious damages caused by lack of
water i the system, particularly duri g first starti g without prior air blowi g-out from heati g
eleme t. Heater ca be co ected to cold water pipe o ly.
Caution!
The heater must never be mounted, disconnected or inclined while being
engaged to electric power system.
The device can only work in position showed on drawing below.
Trying to start the device in position other than proper one will result in
damaging a heating element and deprivation of guarantee.

 State of electrical i stallatio should be periodically checked (voltage drop) a d i particular
electrical co ectio ;
 Electrical power must be switched off before each disco ectio from water system;
 Heater must work o ly i positio prese ted o drawi g No 1;
 Heater should be always i perfect tech ical co ditio a d faultlessly i stalled;
 I case the heater works i correctly power must be switched off a d water must be tur ed off;

 Water flow should be so regulated that water should ot to be too hot (especially for childre );
 The applia ce should ot be i stalled i aggressive e viro me t or da ger of explosio ;
 Heater should ever be exploited with voltage below 200V measured u der load;
 O ly origi al spare parts ca be used for repair;
 Heater ca be co ected to tap assembly delivered by the heaters ma ufacturer;
 All service a d mai te a ce works ca be completed o ly with power switched off;
 Avoid electro ic system to be splashed with water;
 Water tap drai tube spri kler (strai er) should be clea ed regularly.

Assembly
Caution!
Disconnect the heater from power supply prior to dismantling it from tap
assembly. Otherwise heating element can be damaged.
Mounting without conformity to manufacturer s instruction result in dep-
rivation of guarantee.
Clea water tube thread of dirt to elimi ate filter blockage. Fit tap assembly (9) seali g thread with
adequate seali g material. Feed-pipe should ot be retreated i to wall. If a yway it happe ed,
exte sio of 1/2 should be used.
Co ect heater to the tap assembly (9) with uts (5), gaskets (4) a d water filter (3).
Ope water flow to the tap (9). Because dirt ca flow out a d cause filter or water spri kler plug-
gi g, therefore is ecessary:
1  Screw off spri kler (6) from drai tube.
2  Ope cold water tap (8) for few seco ds.
3  Release air-plug by ope i g hot water tap (7) for few seco ds.
4  Screw i spri kler (6) i to drai tube.
Check tight ess of water co ectio s. Co ect heater to power i stallatio a d switch o . Correct
water temperature (chapter 4).
Lack of water filter can cause damage to the heater because of dirt.
4. Temperature adjustment
Caution!
Water temperature on heater exit depends of:
 water flow intensity (lower flow  higher temperature,
higher flow  lower temperature)
 entering water temperature
 voltage drop during heater work

. Cleaning the heater of dirt
Caution!
Disconnect the heater from power supply prior to dismantling it from tap
assembly. Otherwise heating element can be damaged.

4. Remove dirt from filter (1).
5. Replace filter (1) to co ecti g tube (5).
6. Co ect heater to tap assembly (6).
7. Release air-plug by ope i g hot water tap (7) for few seco ds.
8. Switch o power supply.
Sprinkler cleaning
1. Screw out spri kler (4) from drai tube (8).
2. Clea spri kler thoroughly.
I case spri kler is composed of few ri gs screw out co ecti g screw. Take out each ri g.
Remove all dirt (particularly lime scale) a d reco ect all parts.
3. Screw spri kler o to drai tube.

IMPORTANT INSTRUCTIONS
CONCERNING THE DETERIORATED DEVICE
Pursuant to the provisions of the Act dated 29 July 2005 on waste electric and elec-
tronic equipment, it is forbidden to put together with municipal waste the deteriorated
equipment marked with the symbol of the crossed out bin.
A user who intends to get rid of the product, should take the waste electric or
electronic equipment to the point collecting the waste equipment. Collection points are
run, among others, by wholesalers or retailers of such equipment as well as by gmina
organizational units conducting the activity in the scope of collecting waste.
The above statutory obligations have been introduced in order to limit the amount
of waste created from deteriorated electric and electronic equipment, as well as to
ensure the proper level of collecting, recovering and recycling the waste equipment.
In the equipment there are no dangerous elements which have a particularly negative
effect on health and the environment.
The materials used in the device are re-usable. Thanks to re-use, re-use of materi-
als, or other forms of use of the deteriorated devices, you contribute signicantly to the
