ASSEMBLY AND OPERATION MANUAL Pressurized water flow heater PERFECT 7000, 8000, 9000
Advantages of pressurized water flow heaters “PERFECT”: Significant electric power saving comparing to a boiler Instant and permanent warm water delivery Electronic power switch prolongs significantly heater’s life Possibility to use the heater with very low water pressure (ca 0,06 MPa) Thanks to installed electronic control system the most unreliable mechanical parts such as membrane, traditional electrical contacts are eliminated.

Power must be switched off before starting any work over installation, opening cover or incline the installed heater! The heater can only work in position showed on drawing No 1 below.
Heater can only be used when in perfect technical condition Water and power supply must immediately be shut off in case of heater’s failure All service and maintenance works can only be completed with power switched off Only original spare parts can be used for repair Heater’s cover must not be taken away while power is on Avoid electronic system to be splashed with water In case of heater’s defect or improper work switch off power and shut off water supply using stoppin

The device can only work in position showed on drawing No 1. Trying to start the device in position other than proper one or without water filter will result in damaging heating element and deprivation of guarantee. Do not screw connecting hoses using high power in order to avoid thread damage.
Fig. 3 Fig. 4 2. Screw heater on a wall. 3. Connect heater in a way showed on fig. 6. Remember to fit water filter as showed on fig. 5. Use flexible hoses designed for pressurized system with rubber gasket. Do not exchange heater outlet (red colour) with intake (blue colour). CAUTION! Do not screw hose nuts too tight in order to avoid thread damage at heater’s pipes ends. Water filter removal results in guarantee deprivation. Filter must be installed according to figure 5.

4. Open water valve and check connections tightness. In case electronic system is splashed with water remove it immediately blowing with compressed air. 5. Open full water flow in order to remove air plug from heating element. 6. Connect heater to the mains supply. Fig. 7 Caution! Please check whether blue and red gaskets of pipes ends are properly fit to the heater’s casing after fixing it on heater. 7. Change water strainer for the one delivered with heater 8. Adjust heater according to chapter 6 . 9.
7. Water filter cleaning 1. Turn off water inflow to suppressing – shutting off valve and disconnect from power supply. 2. Disconnect flexible hose from heater intake. 3. Take out filter (using small screw driver) – see fig. 8. Fig. 8 4. Remove dirt from filter. 5. Install filter into heater intake with basket bottom down (Fig. 9) GOOD WRONG Fig. 9 6. Connect flexible hose to the heater. 7. Open water valve and check tightness. 8.
9. Defects and troubleshooting Water flow too low –– blocked water filter (clean it out according to chapter 7) Heater does not start –– heater inlet exchanged with outlet –– water flow suppressed too much –– blocked water filter (clean it out according to chapter 7). –– water pressure too low –– lack of power because of blown fuse.
