DIAGRAM MEASUREMENTS

The table below shows suitable duct measurements for each unit. The table below shows the dimensions of the image above and the two images previously, the letter in the table represents the letter on the diagram

INSTALLATION CONSIDERATIONS

Installation Considerations

Protect the unit to avoid dust or other obstructions entering the unit and accessories during installation, or whilst in storage on site. Service ports should be installed to allow access for filter maintenance

1. Be sure the ceiling height is no less than the Figures in above table B column.
2. Unit must not be installed close to boiler flues.
3. The Mark ERV is only suitable as a decentralized heat recovery unit with max. 3-5 meters preferably straight ductwork. The situations below should be avoided. If this advice is deviated from, the maximum air flow rate of the unit will not be achieved.
4. Excessive use of flex-duct and long flex-duct runs should be avoided.
5. Fire dampers must be fitted as per national and local fire regulations.
6. Unit must not be exposed to ambient temperature above 40°C and should not face an open fire.
7. Take action to avoid dew and frost. As shown by drawing below, unit will produce dew or frost when saturation curve is formed from A to C. Use pre-heater to ensure conditions are kept to right of the curve (B to B’,to move C to C) to prevent condensation or frost formation.
8. To avoid the outdoor exhaust air cycling back to indoor, the distance between the two vents installed on the outside wall should be over 1000mm.
9. If heater is equipped to the unit, the operation of heater should be synchronous with the unit, so that the heater starts to work only when unit starts.
10. Duct muffler may be considered if user wants indoor noise to be minimized

Physical Installation

1. Installer to prepare suitable threaded hangers with adjustable nuts and gaskets.

2. Install as shown by the image above. Installation must be level and securely fastened.

3. Failure to observe proper fixing could result in injury, equipment damage and excessive vibration.
   Uneven installation will also effect damper operation.
   Notes for reverse installation of the unit

4. Reverse labeling shows the unit is upside down.

Ducting

1. Connection of unit vents and ducts should be taped or sealed to prevent air leakage, and should comply to relevant guidelines and regulations.
2. The two outdoor vents should face downward toward the outside to prevent any rain water ingress. (angle 1/100 1/50).
3. Insulation must be with the two ducts outside to prevent condensation.

Material: glass cotton, Thickness: 25mm

ELECTRICAL INSTALLATION

Warning

Power must be isolated during installation and before maintenance to avoid injury by electric shock. The specifications of cables must strictly match the requirements, otherwise it may cause performance failure and danger of electric shock or fire. Power supply is AC220V/50HZ/1 Phase. Open the cover of electrical box, connect the 2 wires (L/N/) to the terminals and connect the cable of the control panel to the board according to the wiring diagram, and join the control panel to the cable

COMMISSIONING

Check that all cable sizes, circuit breakers and wire connections are correct before following below commissioning steps:

1. Press the button to turn on/off the ventilator.

2. Match the correct speed to ERV. Press for 6 seconds to enter the parameters setting and at this time the parameter number is shown in the middle of the screen, press button to switch to parameter No. 21 (refer to the parameters list in comming page) then press shortly to enter the parameter setting, default value “0” flesh at the top right corner, press UP and DOWN buttons to change the value according to below table (ERV code Vs Models) then press button again to confirm setting. In the same way to change parameter number 23 to be value 2 (10 speeds DC fan control).
   Code| Models
   ---|---
   3| ERV500
   10| ERV1000
   10| ERV2000

3. Then check the mode and fan speed switch. Press the button shortly to switch to OA, RA, SA or EA mode*, and check whether the temperature of the corresponding mode is correct. Under SA or RA mode, Press to switch the fan speed, and check if the airflow is adjusted corresponding to H speed , M speed and L speed.

4. Check the operation of the bypass. The default opening temperature of the bypass is 19-21C (adjustable), press the button to check the temperature of OA. If the present OA temperature is between 19-21C, then the bypass will open automatically. If the OA temperature is not within 19-21C, say 18C, then press the button for more than 6 seconds to enter the parameter setting. Press the button to switch to parameter number 02, default value 19 flashes shown at the top right corner. Then press the button shortly to enter set, by pressing the buttons and set the value to be “X”. Then press to confirm. To test that the bypass opens, the temperature OA must be greater than or equal to value “X” of parameter 02 and less than the value “X + Y” of parameters 2 and 3 together. X = OA < (X + Y)
   Note: the opening/closing of the bypass will be delayed for about 1 minute. Note: reset the values after this test!

   • Parameter 2: X = 19
   • Parameter 3: Y = 3
   • *OA = Outdoor air
   • RA = Extract air
   • SA = Supply air
   • EA = Exhaust air

TOUCH SCREEN CONTROLLER INSTRUCTIONS

Operation Instructions

1. ON/OFF: press ON/OFF button once for starting; twice for closing. In ON status, backlit LCD display lights up, in OFF status, backlit LCD display off, without operation for 6 seconds, backlit LCD display off too. By pressing ON/OFF button for around 6 seconds can lock and unlock the controller.
2. Mode switch: press MODE button to choose display the RA-OA-FR(EA)- SA Setting-CO2 status or Humidity control status.

Remark:

1. Under SA setting mode, after connecting the electrical heater according to the electrical diagram and change parameter 01 to value 1, users can set the supply air temperature by pressing up and down button.
   The setting temperature range is 10-25°C.

   • A) 0°C setting temperature minus SA temperature <5°C 1st stage heater on, 2nd stage heater off
   • B) Setting temperature minus SA temperature >5°C1st and 2nd stage heater on

2. The CO2 symbol appears when the CO2 sensor is connected. ERV runs at boost speed when CO2 concentration higher than setting value.

3. The humidity symbol appears when the “temperature and humidity sensor” is connected. ERV runs at boost speed when humidity higher than setting value. Under “humidity control” mode, users can set the setting humidity by pressing up and down button. The setting range is 45% ~ 90%. And the Dial switch SW4-3 on the PCB should be switched ON to switch from CO2 control function to humidity control function.

• Air volume setting: Under SA or RA temperature interface. Users can set the return air volume in “RA” status, and set the supply air volume in “SA” status by pressing up and down button. Totally 10 speeds control.
• Error code checking: under the main interface, press the SET button for short, user can check the error code of ventilator, refer to below table.

• Bypass setting: when bypass is on, the triangle bypass symbol appears, when bypass is off, the sym-bol  disappears.
• Filter alarm: When running time of ventilator is over the setting filter alarm time, the filter alarm symbol flashes to remind user clean/replace the air filters. After filters being cleaned/replaced, please sweep the filter alarm by setting parameter Number 24, value 1.
• Parameters setting: Keep pressing the MODE button for 6 seconds, after buzzing to enter the parameter setting interface

After entering the parameter setting interface, press SET button shortly to change the parameter number, every pressing will make parameter value +1 (until number 24 then repeat again). After choosing the correct parameter number, press Mode button for short, parameter value flashes at the top right corner, at this time to change the value by UP and DOWN buttons. After parameters setting then press SET button to save.

Instruction of Parameter Settings

1. Parameter 00 refers to power to auto restart
   • 0: Invalid, 1: Valid
2. Parameter 01 refers to Supply air electrical heater function
   • 0: Not available 1:Available When connecting with supply air electrical heater, user should choose 1 to activate the electrical heater, and under the SA temperature setting interface, the SA temperature can be set by pressing up and down button. The setting temperature range is 10-25°C.
3. Parameter 02-03 refers to automatic bypass function The bypass is opened on the condition that the outdoor temperature is equal or higher than X (parameter 02)and less than X+Y (parameter 03). Bypass is closed on other conditions.
