2. Nomenclature
Throughout this program reference to “deicing” and “anti-icing” will be made for the purpose of describing a component and/or system.
The term “deicing” will refer to the Type I fluid system.
The term “anti-icing” will refer to the Type IV fluid system.

3. Deicer Operation
The following section outlines the operating instructions for the deicer including the below listed items:
Before Use Inspection
Start-Up Instructions
Shut-Down Instructions
Suction Fill Deice
Suction Fill Anti-Ice
Aerial Lift Operations

4. Before Use Instructions
Visually inspect the deicer for any physical damage.
Check underneath vehicle for any drips or puddles of fluid.
Visually inspect components housed within deicer cabinet for any uncommon markings
Check fluid levels in the fluid storage tanks and secure filler cap(s).
Check operation of Communication System.
Visually inspect heater plenum screens for excess blockage.
Check fluid levels for chassis engine and auxiliary engine.
Ensure that all control panel switches are in the "Off" position.
If any of the above inspections seem irregular, contact Premier Engineering prior to proceeding.
BEFORE USE INSPECTION
Warning: Compliance with the Before Use Inspection is mandatory to ensure the safe and proper operation of the unit. Failure to perform the "Before Use Inspection" may result in damage to the unit or personal injury. All operators must be thoroughly trained in the operation of the machine and be familiar with the inspection requirements and operational procedures detailed in this technical manual.
Visually inspect the deicer for any physical damage. This inspection should include checks for cabinet or chassis damage, flat or under-inflated tires, all clearance lights, emergency lights, headlights and turn signals.
All damage to the cabinet should be noted in the maintenance log. Although damage may at times seem superficial, components housed within the cabinet can be affected. Furthermore, the integrity of the mounting system which couples the chassis to the cabinet can be affected if the cabinet has been impacted.
All operational lights should be checked prior to each use. In many cases the lights are for the safety of others as much as the operator of his/her own vehicle.
The stability of the unit is dependent on the integrity of the tires. Under inflated or flat tires jeopardize the safety of the individual in the basket.

5. Check underneath vehicle for any drips or puddles of fluid.
Fluids accumulating under the cabinet can be reason for concern. Special attention should be made of the areas under the chassis and auxiliary engine, aerial lift, Hydraulic reservoir, fuel tanks, fluid storage tanks, and heaters. If accumulation is present, it is strongly advised that further investigation be done prior to proceeding.
Visually inspect components housed within deicer cabinet for any uncommon markings, i.e. burned or scorched marks on electrical components, frayed or scorched wiring, etc..
All of the major components for the deicer are housed within the cabinet enclosure. Visually inspecting the components on a regular basis can help detect premature wearing and potentially failing components, i.e. belt dust from the engine, excess oil on the engine, grease dripping from bearings, etc….
Check fluid levels in the fluid storage tanks and ensure secure placement of filler cap(s).
It is not only important to check insure there is adequate levels of deice and anti-ice fluid(s) in the tanks to complete the operation, but also to insure the proper mixture/ratio of the fluid for the conditions. Low levels of fluid can cause the system to not operate properly as well as require refilling during the deicing/anti-icing process. Insufficient mixture/ratio of fluid in deice tank can result in inappropriate application to the plan and/or sever damage to the unit.
Check operation of Communication System.
Communication between the basket and chassis cab is critical to the a safe deicing event. It is not recommended to proceed with the deicing event if the communication system is inoperable.
Visually inspect heater plenum screens for excess blockage.

6. Check fluid levels for chassis engine and auxiliary engine, including oil, fuel, coolant, washer fluid on chassis and at basket, power steering and application fluids.
Fluid levels of the various components are critical to the safe and reliable operation of the unit. Although the components used on the ABS system are rugged and dependable, they are not immune to failure. Even though accumulated fluid may not be present under the unit, fluid levels can still be diminished and could result if component failure. There are safety shutdowns installed to prevent excessive damage in the event of a low fluid levels, however, the inconvenience of having to stop the deicing process is preventable.
b. Levels to be checked as part of the before use inspections are:
Chassis and Auxiliary Engine Oil and Coolant Level
Chassis and Auxiliary Engine Fuel Levels
Hydraulic Oil Level in Aerial Lift, Hydraulic tank, and Generator.
Compressor Oil Level
Window washer levels in chassis and enclosed basket.
Ensure that all control panel switches are in the "Off" position.
a. Attempting to start the motor with components energized adds stress to the starter on the engine. This can result in premature failure of the starter, increased amperage draw on the electrical system, and inadequate power supplied to the various components.
If any of the above inspections seem irregular, contact Premier Engineering prior to proceeding.
a. If a condition exists that is un-explainable or does not have a logical explanation, we strongly urge you to contact Premier with a report. In an effort to better support our product, we need to be proactive in identifying problems, tracking those problems, and generating a solution prior to further failures.

8. Control Panel
The deicer function controls are located in the chassis cab of the deicing unit.
All deicer components are equipped with a rocker style illuminated switch.
When the switch is in the “OFF” position, the rocker switch will be in the non-illuminated position.
Conversely, when the rocker is in the “ON” position, the rocker switch will be illuminated.
All heater switches are accompanied by an ignition light located directly above the corresponding rocker switch and indicates the burner operation of the burner.
