Yes, a GFCI breaker is required.

The optimal pressure value depends on the current ambient and water temperatures. Under normal conditions, the appropriate pressure range (as indicated by the high-pressure gauge) is 1.6–2.6 MPa; however, under extreme operating conditions, the pressure may exceed 3 MPa. If this response does not resolve your issue, please contact us again for assistance.

Water flow is optimal when the difference between the inlet and outlet water temperatures is 4°F (2°C). It is recommended to set the target temperature to 83°F. If this answer does not resolve your issue, please contact us again for assistance.

To set this up, wire your lights or auxiliary equipment to the dedicated linkage/relay terminal ports on the heat pump's main PCB, then configure the linkage mode within the mobile app's settings menu to enable remote switching. Because this process involves low/line voltage connections on the control board, we recommend consulting a qualified electrician to ensure proper wiring according to local electrical codes.

Thank you for contacting VEVOR support regarding our Max 93,390 BTU Electric Pool Heat Pump. Yes, that is correct; the linkage switch feature allows you to connect external equipment—such as pool lights or an auxiliary water pump—and synchronize or control their power state directly via the heat pump’s control board and companion smart app

The unit can operate at a minimum ambient temperature of -7℃, which is approximately 19°F; this is the lowest outdoor temperature at which it will function—there is no explicit “low temp shut-off point” stated, but operation ceases below -7℃.
