Remove the mounting plate from the rear of the indoor unit and position it against the wall where the system will hang. Use a level to ensure the plate is perfectly aligned.2. Drill holes 1-1/4 inch (32 mm) deep for each screw. The locations are flexible but should be well-spaced.<img src="https://attachments.gorgias.help/Q9r0k7BYaV2vg13y/hc/9JWjXVxG8m6DvMqm/2026071420-25454ee5-7dde-4dcb-9b52-59b76043b856-wyt17_idu_mounting_plate.png" style="width: 500px;" class="fr-fic fr-dib fr-bordered">3.

After firmly attaching the mounting plate to the wall, temporarily mount the indoor unit onto the plate to confirm the wall hole location.<img src="https://attachments.gorgias.help/Q9r0k7BYaV2vg13y/hc/9JWjXVxG8m6DvMqm/2026071512-ac5d6f3b-4ebb-4a45-b50c-565002880690-wyt17_idu_drill_piping_hole_1.png" style="width: 500px;" class="fr-fic fr-dib fr-bordered"> 2. Use a pencil to lightly trace the bottom corner of the indoor unit, depending on which side the piping will exit.<img src="https://attachments.gorgias.help/Q9r0k7BYaV2vg13y/hc/9JWjXVxG8m6DvMqm/2026071512-aa732d6b-0d01-4bfd-b7a2-ec879188fb04-wyt17_idu_drill_piping_hole_2.png" style="width: 500px;" class="fr-fic fr-dib fr-bordered">The pre-attached piping pigtails on the indoor unit can be routed in three ways. For a side exit, use a suitable cutter to remove the knock-out panels along the groove to create a pipe exit notch.<img src="https://attachments.gorgias.help/Q9r0k7BYaV2vg13y/hc/9JWjXVxG8m6DvMqm/2026071512-6e06d42e-a11a-47b6-af7e-5f1278974f2f-wyt17_idu_piping_direction.png" style="width: 500px;" class="fr-fic fr-dib fr-bordered">By default, the piping is routed for a left-side exit (Option 1). This method can use either the left-side knockout for a side exit or a wall hole drilled to the left of the unit&apos;s rear.We recommend routing the piping through the back of the system (Option 2) to easily connect the copper pipe extensions.Routing the piping for a right-side exit (Option 3) is possible but not recommended. This configuration requires a 180-degree bend, which severely increases the risk of the lines kinking or collapsing. If this layout is required, bend the piping slowly and cautiously. 3. Remove the indoor unit from the plate and mark the hole location, ensuring ample clearance between the mark and bracket.<img src="https://attachments.gorgias.help/Q9r0k7BYaV2vg13y/hc/9JWjXVxG8m6DvMqm/2026071512-0b366b64-8c03-4b60-ab04-5844dd8c7182-wyt17_idu_drill_piping_hole_3.png" style="width: 500px;" class="fr-fic fr-dib fr-bordered">Recommended wall hole locations for our wall-mounted systems are listed at the bottom of this article. These measurements accommodate both left- and right-side exits with a 2-&#xBD; inch (63.5 mm) hole. Verify the hole locations by performing corner tracing. 4. Using a core drill, drill a 2-1/2 to 3-1/8 inch (63.5 to 79 mm) hole through the wall at a slight downward angle.<img src="https://attachments.gorgias.help/Q9r0k7BYaV2vg13y/hc/9JWjXVxG8m6DvMqm/2026071512-08b8b250-06f8-4677-8340-e6133859b35b-wyt17_idu_drill_piping_hole_4.png" style="width: 400px;" class="fr-fic fr-dib fr-bordered">Be careful to avoid wires, plumbing, and other sensitive materials.

Improper installation may cause property damage.The indoor unit features two drain connections, located on the left and right sides. By default, the drain line attaches to the left side of the unit (when facing the back). One side connects to the hose, while the other remains plugged.<img src="https://attachments.gorgias.help/Q9r0k7BYaV2vg13y/hc/9JWjXVxG8m6DvMqm/2025120121-df92823e-eb3a-4948-8b88-82c378fc6024-wyt17_drain_hose_ports.png" style="width: 500px;" class="fr-fic fr-dib fr-bordered">The drain hose for <a href="https://www.pioneerminisplit.com/collections/quantum-fresh-series-breathe-the-difference" target="_blank" rel="noopener noreferrer">Quantum Fresh (WYT-FA)</a> systems can only attached to the right-hand side of the unit.

Plan the Drain Line LayoutBefore beginning the installation, plan the drain line layout and connection.&#xA0;B. Cut the Drain Line (If Needed)If necessary, cut the drain line to fit your layout and connection.C. Insulate the Drain Line (If Needed)Verify that the drain line is insulated to prevent condensation and potential water damage. If it is not, insulate it properly. Insufficient insulation may allow dew to form due to low condensate temperatures, resulting in potential water damage.Insulate the drain line before beginning the connection, excluding the joint sections. These will be insulated at the end of the procedure.&#xA0;Ensure the insulation material is fitted tightly with no gaps. Do not over-tighten the insulation material. This may compress the air out of the material, causing poor insulation and early aging.The insulation material must be made of flame-retardant material. Select a material that complies with local regulations.&#xA0;The thickness of the insulation material must be more than 3/8 of an inch (10 mm).&#xA0;Apply specialized adhesive to the insulation seams, then secure them with tape. Ensure the tape is at least 2 inches (51 mm) wide and applied firmly to prevent condensation.&#xA0;D. Connect the Drain Hose1. Attach the drain line on the same side where the refrigerant piping exits the unit.&#xA0;2. Attach any optional extensions (sold separately) to the end of the drain hose.&#xA0;3. Wrap the drain line connection firmly with Teflon tape to ensure a tight seal and prevent leaks.4. For the portion of the drain line that will remain indoors, wrap it with foam pipe insulation to prevent condensation.E. Pass the Drain Line Through the Wall HoleWhen passing the drain line through the wall hole, make sure the water drains to a safe location where it will not cause water damage or a slipping hazard.<img src="https://attachments.gorgias.help/Q9r0k7BYaV2vg13y/hc/9JWjXVxG8m6DvMqm/2026071514-eb20f1d5-abdf-463b-b5b0-673f7cf9a376-wyt17_idu_connect_drainpipe_yesno.png" style="width: 400px;" class="fr-fic fr-dib fr-bordered">The drain line outlet should be at least 1-7/8 inches (50 mm) above the ground. If it touches the ground, the unit may become blocked, potentially leading to a malfunction.If the water is discharged directly into the sewer, ensure the drain has a U or S pipe to prevent odors from coming back into the house.F. Complete a Drainage TestEnsure the condensate drains to a suitable location by completing the drainage test.

Insulate the Drain Line Joint SectionsThe drain line joint insulation should be 2~4 inches (51~102 mm) longer than the gap to ensure a proper seal.Insert the joint insulation into the gap of the existing insulation.Ensure the joint insulation is securely fastened to the suction and liquid pipes to prevent gaps. Use adhesive to bond the joints together. Do not over-tighten the insulation material; this can compress the material and release the trapped air, causing poor insulation and premature aging.
