Description
HOTSTART OW Weathertight Lube Oil Heater. Use a thermostat with all lube oil heaters to protect the oil from overheating. Lube oil heaters must always be installed in the sump with the entire heater submerged below the oil level at all times. Oil heaters up to 277 V AC meet recognized CSA standards for safety or performance. NOTE: If heating gear oil (medium weight viscosity), HOTSTART recommends using low watt density heaters. See page 21 for remote thermostat part numbers.
- Cord: Weathertight heater-only models are furnished with a 4′ (1.2m) oil- and heat-resistant power cord without plug.
