WARNING: ELECTRICAL SHOCK HAZARD. Failure to follow these warnings could result in death or serious injury.
• Before carrying out any work on electrically operated components, make sure they are disconnected from the power supply.
• Before installing the HD Series, disconnect all connections to the vehicle battery.
• Make sure all power connections are tight and secure. Important! When connecting power terminals inside the compressor box
unit you MUST torque the power post to 140 in-lb (15.82 Nm).
• All electrical connections should be made by a trained technician.
• CAUTION: PERSONAL INJURY HAZARD. Incorrect installation of the HD Series may place the safety of the user at risk.
Failure to obey this caution could result in minor or moderate injury.
NOTICE: The HD Series should be installed by a qualified technician.
NOTICE: The connection to the vehicle's electrical system should be protected by a fuse recommended for your system. Please
visit www.bluesea.com and click on Circuit Wizard for guidance on properly sizing wires and breakers.
NOTICE: The battery must be capable of supplying the required current and voltage.
• When handling our products, always use protective gloves and protective footwear. The product is made from mostly stainless
steel and can have sharp edges that can cut you. The units are also very heavy, so lift with 2 people- never alone, and make
sure before lifting that ALL screws are tight when securing the cover. 2 of the screws in the middle on the long sides and 1 on the
backside keep the cover from sliding off. It's very important that they are put in and secured before moving. When installing
cover screws, make sure unit is level and make sure holes are aligned. Do not force screws. They are stainless steel and will
seize.
• Do not add any oil when charging this unit with refrigerant. The compressors are pre-charged with PVE oil.
• If oil leaves the unit during future recoveries, you may add the amount that left the system with more PVE oil. Call us for info on
the viscosity. Never add PAG oil or leak dyes that are not compatible with PVE oil. Call us and we can recommend a suitable
leak dye. PAG or PAG electric oil will ruin the compressor and void your warranty.
Do not reverse
polarity. Damage will result and void your warranty.
