Install ECOasis 150 Energy Recover VentilatorsUpdated 4 hours ago
Introduction
This article explains how to install ECOasis 150 Ductless Wall-Mounted Single-Room Energy Recovery Ventilators.
There are two installation scenarios available. Select from either the rear or side of the equipment for the air inlets and outlets.
Note: Use caution to prevent dropping hardware into the ventilator during installation.
Rear Installation
1. Choose a suitable location on the wall where the equipment will be mounted. Mark the intended locations of the outdoor air inlet and and exhaust air outlet. In addition, mark the five mounting holes of the installation panel on the wall. 
Clearances:
- Ventilator bottom to the floor is around 5 feet (1.5 m).
- Ventilator left and right side to the wall is no less than 1 foot (0.3 m).
2. Drill two holes in the wall for the fresh air inlet and exhaust air outlet, each with a diameter of 4 inches (102 mm).
The two holes should angle downward toward the outside to prevent rain water ingress, with a minimum downward slope of a 1/4 inch per foot (18 mm per meter). For the five mounting holes, the recommended size is a 1/4 inch drill bit and a 2-3/4 inch deep hole (Φ6 x 70 mm). Insert the five plastic anchors in the mounting holes.
Note: The hole sizes of the outdoor air inlet and exhaust air outlet are given according to the Pioneer accessories (straight PVC pipes). If the piping is of a different size than what is included, ensure that the wall holes are matching accordingly.
3. Fasten the flange to the installation panel, using the included M3x12 bolts and nuts. 
4. According to the thickness of the wall, cut the suitable length of the PVC pipes. Connect the PVC pipes to the outdoor air and exhaust air accessories as follows:
- OA side: PVC pipe + Air inlet grille + Rain proof cover + Rubber sealing ring + Tapping screws
- EA side: PVC pipe + Air outlet grille + Rain proof cover + Rubber sealing ring + Tapping screws
Note: Before installing the fastening screws, it is necessary to drill holes of Φ 1/8 inch (3 mm).
5. Slide the assembled ducts into the wall. Ensure that the rain cover is appropriately oriented downwards, preventing rainwater ingress.
Next, seal any gaps between the duct and wall using appropriate field-supplied materials like silicone or waterproof putty. 
6. Secure the ERV installation panel onto the wall using the supplied knock-on anchor bolts.
7. Cut the EPS "rear cover" located at the outdoor air vent. Do not cut the EPS "side cover" in this installation scenario. 
8. Cover up the side air inlet and side outlet by placing the two round outdoor air and exhaust air covers on them.
Secure the two seal rings to the rear of the air inlet and outlet.
9. Secure the rear plate thermal insulated cotton/foam onto the rear side of the ventilator if necessary (near the outdoor air side). This assists with preventing condensate water from forming when the ventilator is deployed in cold areas.
10. Hang the ventilator on the installation panel. Adjust the four M5x18 hanging screws on the back of the ventilator to suit the installation panel.
11. After the installation is completed, power on the ventilator.
Side Installation
1. Secure the two sealing rings onto the side flanges. Fasten the flanges to the ventilator side using the included M3 bolts (8) and M3 nuts (8).
2. Cut the EPS "side cover" located at the outdoor air vent. Do not cut the EPS "rear cover" in this installation scenario. 
3. Choose a suitable location on the wall where the equipment will be mounted. Mark the intended locations of the outdoor air inlet and and exhaust air outlet. In addition, mark the five mounting holes of the installation panel on the wall according to the ventilator placement.
Clearances:
- Ventilator bottom to the floor is around 5 feet (1.5 m).
- Ventilator left and right side to the wall is no less than 1 foot (0.3 m).
4. For the five mounting holes, the recommended size is a 1/4 inch drill bit and a 2-3/4 inch deep hole (Φ6 x 70 mm).
Drill the holes with reference to the panel, then insert the five plastic anchors into the mounting holes.
5. Drill two holes in the wall for the fresh air inlet and exhaust air outlet, each with a diameter of 4 inches.
The two holes should angle downward toward the outside to prevent rain water ingress. Ensure the minimum downward slope is a 1/4 inch per foot (18 mm per meter).
When drilling outlet holes on the wall, the opening hole size is only a recommended value. For the side installation scenario, the ducts should be flexible ducts (field supplied by the installer). The final hole size on the wall should be selected by the installer, according to the diameter of the duct being used.
6. Hang the ventilator onto the installation panel. Adjust the four M5x18 hanging screws on the back of the ventilator to suit the installation panel.
7. Cut the suitable length of the PVC pipes, according to the thickness of the wall. Connect the PVC pipes to the outdoor air and exhaust air accessories.
- OA side: PVC pipe + Air inlet grille + Rain proof cover + Rubber sealing ring + Tapping screws
- EA side: PVC pipe + Air outlet grille + Rain proof cover + Rubber sealing ring + Tapping screws
8. Slide the assembled ducts into the wall. Ensure that the rain cover is appropriately oriented downwards, preventing rainwater ingress.
Next, seal any gaps between the duct and wall using appropriate field-supplied materials like silicone or waterproof putty. 
9. Secure the other end of the installed piping onto the flanges on the side of the ventilator.
10. After the installation is completed, power on the ventilator.
