SAFETY Check coolant levels when the system is cold. BEFORE YOU START Refer to the applicable engine manufacturer’s owner’s manual to determine the correct coolant required. PROCEDURE Establish a Baseline • Coolant level in the reserve coolant tank should be at the “Full” mark. • The radiator cap must be removed and the coolant level in the radiator checked. o Coolant level in the radiator should be at the base of the filler neck. Daily maintenance • Verify that the coolant level in the reserve coolant tank is correct. • Verify that the radiator coolant level is correct (in units where the radiator cap is accessible). IF COOLANT LOSS IS DETECTED Units with cabinet heating system connected to the Multifunction Check all cabinet heating system hoses and connections to and from the Multifunction, ensuring all connections are tight and there is no leakage. • Replace any leaking components and/or correctly tension any loose clamps. If a leak is not found in the cabinet heating system, or a cabinet heating system is not installed, and a leak within the Multifunction Power System is suspected: Contact VMAC Technical Support at 1-888-241-2289 or tech@vmacair.com Do not operate the Multifunction Power System until coolant leaks have been repaired and system coolant is at the recommended level.
