Introduction

This article explains how to install ECOasis 50 Ductless Wall-Mounted Single-Room Energy Recovery Ventilators. 

Steps

1. Drill a 6-1/4~6-3/4 inch (160~170 mm) round hole in the wall. The hole size is shown below.

2. Insert the PVC pipe into the hole. Adjust the pipe so it fits flush with both the interior and exterior sides of the wall. 

To ensure an airtight seal, use PU foam to fill the gap between the PVC pipe and the wall on both the indoor and outdoor sides. 

Important Notes

• The duct consists of two outer ducts and can be adjusted to accommodate wall thicknesses of up to 19-5/8 inches (498 mm). 
• If the wall thickness is less than 14-5/8 inches (371 mm), the duct can be cut to size according to the wall thickness. 
• For installation instructions of the outer grille, refer to the grille package. 

3. Insert the PVC pipe into the wall. Adjust the pipe to fit snugly against the wall. 

Use PU foam to fill the gap between the PVC pipe and wall, both inside and outside the building. 

Open the hood cover and align the bottom of the hood base with the circular opening of the pipe. 

On the outside of the wall, mark the positions for the four screw holes on the base of the exhaust hood. 

Drill the holes, then secure the bottom of the plastic hood using appropriate hardware. 

4. Install the main unit on the indoor surface wall. Connect the adapter wire from the back of the main unit to the wiring of the fan and temperature sensor exposed in the inner duct. After completing the connection, tidy the wiring. 

Align and install the main unit with the protruding plastic and metal parts on the back cover plate. There are corresponding concave holes on the rear of the main unit. 

The strong magnet equipped on the back of the main unit will automatically attract the wall mounting plate. 

Finally, turn the two small M3 screws (included in the kit) into the hole at the top of the main unit. 

The installation is complete. 

After Installation is Complete

Check if there is a large gap between the main unit and mounting plate. If so, it means that the wires in the main unit are not placed properly. Remove the main unit and reinstall it.
