ASSEMBLY AND OPERATION MANUAL Pressurized flow through water heater PERFECT 3500, 4000, 4500, 5000, 5500
Advantages of pressurized flow through water heaters “PERFECT” Serious electric power saving comparing to boiler Instant and permanent warm water consumption Installed 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.

It is strictly forbidden to assembly, disconnect and incline the heater on sides while power is switched on.
In case of heater’s defect immediately cut off water and power supply. All service and maintenance works can be completed only with power switched off Only original spare parts can be used for repair Casing should never be disassembled 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 stopping – suppressing valve.

Assembly CAUTION! The device can only work in position showed on drawing No 1. Heater’s installation in position other than proper one or without water filter can damage heating element and cause deprivation of guarantee.
Fig. 3 Fig. 4 2. Screw heater on. 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 gaskets. Do not exchange heater outlet (red colour) with intake (blue colour). Caution! Do not screw up hoses nuts too tightly in order to avoid heater’s pipes thread damage. Water filter removal voids guarantee. Filter must be installed as showed on drawing No 5. Fig.

4. Open water valve and check all connections tightness. In case electronic system is splashed with water, remove it by blowing with compressed air. 5. Open full water flow through the heater in order to deaerate heating element. 6. Connect heater to the power installation. Fig. 7 Caution! Every single time after re-instalation of the housing it is necessary to check carefully whether blue and red gaskets on pipe ends fit close to the heater’s housing nests. 7.
7. Water filter cleaning 1. Turn off water inflow to suppressing – shutting off valve and disconnect from power line. 2. Disconnect 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) Fig. 9 6. Connect hose to the heater. 7. Open water valve and check tightness. 8.
9. Defects and repair Water flow too low – blocked water filter (clean it out according to chapter 7) Heater does not start – heater’s inlet exchanged with outlet – water flow suppressed too much – blocked water filter (clean it out according to chapter 7). – water pressure in system too low – lack of power because of blown fuse.
