TRITON BRAND AUTOMOBILE SPRAY BOOTH
Please read this using manual carefully and save well before using this equipment!
I. Operational principle:
1. Normal spraying: turn on control power supply?lighting power supply?spraying switch, then intake system working, close the damper of inside recycle. (5). At the moment, the fresh air goes through the pre-filter by intake air fan (1) first to be filtered off the granule of dust, and enters into the intake air fan and air intake room, then filtered by ceiling filter (2) and into the booth which filter 98% dust of air, keep the fresh air when spraying. The air is not less 0.3m/s going down, to be effected by exhaust air fan, will bring the paint. First, pass fiberglass filter underneath the grills. (3) To absorb air dust, in order to protect operator healthy and surface quality of painting. Then filter by environmental protection cabinet. (4)Fully absorb paint and clean dust out.
Air flow: intake air mouth? pre-filter? intake air valve? intake air fan? heat exchanger? static pressure room? sub-high efficiency filter? spray room? floor filter? environmental protection cabinet? exhaust air fan? exhaust air duct? atmosphere ( refer to the flow chart for purifying air)
2. Heat spraying: The ambient temperature is below 20? (usually, it is below 10?), firstly start up the power supplier, setting the risen-temperature scale, turn on the light switch, turn off the baking switch, the risen-temperature spraying is on. At this moment, the intake& exhaust air fan, burner start to work and the inner circulation damper is closed. The air is heated at this process and the working principle of normal temperature spraying is the same as this.
Air flow: intake air mouth ?pre-filter ? intake air valve ? intake air fan ? heat exchanger ( the air is heated up for spraying) ?static pressure room ?sub-high efficiency filter ?spray room ?floor filter ?environmental protection cabinet ?exhaust air fan ? exhaust air duct ?atmosphere ( refer to the flow chart for purifying)
3. Baking: Before baking, please setting baking temperature and baking time, turn off the light switch, and then turn off the spraying/risen-temperature, turn on the baking switch, enter into the paint baking process of the state of auto-complete. When the intake air starts to work, the auto-controlled burner will ignite. According to temperature control meter set temperature for automatically controlling heat power, in order to keep invariableness temperature. At the moment, the outside air is only 15% fresh. Passing the pre-filter into the intake air cabinet, the intake air cabinet into heating system to heat up, then into air intake room.(2) Passing the high efficiency filter into inside spray booth., most hot air are filtered then goes through pneumatic recycle damper with hot air.(5)It being inhaled and heated up again when through the heat exchanger. At the moment, it saving power, temperature inside room will increase rapidity, the hot air is filtered twice being clean air, after heating up on the surface of automobile.
Air flow: Inside air? inside recycle damper? intake fan? heat exchanger (air is heated in need) ? air intake room? filter? spraying room? pre filter for recycling twice? inside recycle damper

(3).Before operation, the temperature must be set to avoid the high temperature. The initial temperature is 20?.
(4). If need to stop urgently, please press the emergency stop to auto-close.
5. Baking switch
(1). On the condition that thermometer and time scale have been set up well, turn on the baking switch and the intake air fan starts up, the burner starts to ignite and heat up, and the thermometer auto-control. Check the setting current value of the thermometer before it starts up in order to avoid the temperature being too high. Initialized value is 60?.
(2). When the baking switch is turned off, the control system will be closing and protecting state automatically, at the same time, the burner stops heating, the intake/exhaust air fan will stop last for 2 min. the initial time is 2min.
(3). When the baking time arrive to the setting one, the power supplier is auto-closed, and the air fan still runs, the heating exchanger run last for 2mins. The initial one is 2min.
(4). If you want to set the time, please turn off the baking switch first, then adjust the value of the timetable to make sure input correctly,
(1). Turn the light switch left, the left lamp is light.
(2). Turn the light switch right, the right lamp is light.
(3). When baking, the light stops running, the other operation will not affect the lighting.
7. Baking-time accumulator
(1). Setting method in detail: adjust the switch to the number you need, for example: (0.3.0.0) means 30 minutes.
(2). Set the baking time (0-9000min) to heat the burner.
To make sure the correct input, power off after set the time up well, and then reconnect it in 2 seconds.
When intake/exhaust air fan starts up, the time accumulator begins accumulating and displays the current data of running time. When the exhaust fan stops working, so is the time accumulator. Please replace the filtering cotton after the time reaching to 400h.
(1).The pressure is -15 or +20Pa when normally use spraying and risen-temperature

IV. Installation and Debugging
1) Please check the control cabinet and control panel whether there are damage or not, and the components and cable head inside the cabinet whether have been broke off, loose or not?
2) Make sure the direction of intake/exhaust air fan, burner, lighting power cable, and use insulated duct to protect these cables.
3) Please follow the rule of operation for the electric appliance strictly when you connect the control cabinet.
4)Cross section area of burner power supply wire?4x1mm2?
Cross section area of lighting power supply wire?3×2.5mm2?
Cross section area of damper power supply wire?3x1mm2?
Cross section area of intake fan (4Kw) power supply wire?2.5×4mm2?
Cross section area of exhaust fan (5.5Kw) power supply wire?4×4mm2?
Cross section area of control panel power supply wire?16mm2?
5) The line which must through the wall should match with protective layer and far away from heat source. And the line which is near to the rotary parts should be fixed well.
6) Outside shell of ventilator, control box, temperature control meter should be connected with earth wire.?bury earth-plate if possible?
7) Electrical appliances must be installed under the guidance of professional technical personnel of electrical engineering, strictly follow the circuit diagram, operating instruction and it is prohibited to operate by the personnel without permission.
1) To test out the flexibility of fan’s mechanical transmission by eyes and hands.
2) To test by eyes whether the heat overload value, circuit breaker and the main switch are in accordance with the circuit diagram or not.
3) Try to electrify to fan and confirm that it runs as the positive direction.
4) Adjustment of normal temperature spraying
The breaker of power supply is on, emergency stop button (SB) is connected, the power supply switch is on, the lighting indicator lamp is light, and the temperature controller does not participate in this process. The normal temperature spraying switch “ON1” is on, its indicator lamp is light, and the time accumulator starts to work, inner circulation damper is open. The intake air fans start up, so is the exhaust air fan in few seconds later. And then the whole system is on normal temperature spraying cycle.
5) Adjustment of risen-temperature spraying
When the ambient temperature is too low, for ensuring the quality of spraying, we must use the burner to heat up.
Setting the spraying temperature (usual is about 20?), meanwhile, turn on the risen-temperature spraying switch (SA), its indicator lamp will light, and the time accumulator starts to work, inner circulation damper is open. The temperature controller participates in this process to auto-control the burner working. The temperature in booth keeps at about the pre-set one. And the working principle of other electric appliances is same as the normal temperature spraying cycle.
6) Adjustment of baking
1. First, the spraying switch is at “OFF” position, setting the baking temperature (we have set at 60? initially), turn off the lighting switch, then, turn on the baking switch, next, set the baking time.
2. Electrify to electric damper and turn the open position into closed. On baking, the hot air will circulate inside booth.
3. Baking indicator lamp is light, exhaust air fan stops working, and only one intake fan running at rated speed.
4. The burner failure indicator lamp is light when the burner fails to ignition on baking cycle.
5. The burner will stop working when there is something wrong with the intake air fan during baking cycle. The temperature regulator (KO2) as the exceed-temperature protector device controls the temperature inside booth.
6. The state of the burner will be controlled by the temperature regulator which controls the baking temperature automatically. Once the baking section is setting, all steps will be followed as the auto-control state to finish the baking process.
7) Electrify to lights, connect the contactor, at this time, all the lights should be alight.
8) The setting value of temperature controller should be corresponding at 115?.
9) Adjustment of temperature controller (we have set at 0-60 initially)
Risen-temperature spraying setting is at 20?, baking temperature setting is at 60?.
10) Adjustment of burner
The object of heating is closely related to the use situation. When the pressure of heat exchanger increased, air capacity output will reduce, thus must reduce the pressure (or use smaller nozzle) to reduce oil volume, and then the combustion capacity will go down. On the contrary, it needs to increase the capacity of combustion, please refer to instruction manual of burner (the burner is in the best state as the practical running environment before leaving factory.) so place the burner in heating exchanger to adjust.
Adjustment of oil volume with adjusting-screw: adjustment at the clockwise direction will increase the oil volume. On the contrary, at the counterclockwise direction will reduce the oil volume.
When on adjustment, please increase the oil volume, air capacity as large as possibly and there is no heavy smoke appearing is better, which means the burner is in the best working condition.
11) Adjustment of electric damper
After installing the pneumatic damper, please confirm the direction of damper and ensure the open degree of damper.
V. Methods of Common Troubleshooting
1. Once the fan starts up, power supply cut off.
Check: heat over loading value? connect earth wire? insulated between phase wire (disconnect loading) ? phase wire ground insulated
2. After starting up air fan, appears abnormal voice, then power supply cut off.
Check: if the heating over loading value is enough or not? melting point of fuse? if the main power supply is lack of phase or not? the temperature of fan surface goes up (judge if it is over load strictly or not)
3. Burner fails to ignite
1). Contact power supply circuit
To check whether it is connected or not?
2). To check whether the photographic switch is shaded, damaged or not?
The pre-voltage of high voltage generator is 220V, sub-wire is connected well, electrode distance. Is there electric arc discharged by high voltage?
3). Connect on power to the magnet valve, check whether the valve works or not?
4). Adjust the damper to check whether the intake air volume is too much or not?
5). To check whether there is water mixing with the diesel oil or not? Or the air in oil box is not exhausted completely.
6). The control box is damaged.
4. The burner works unstably
1). Go out automatically after ignition
Check: if the outside shell of photographic switch is shaded by dust or not, there is no photoreceptor signal feedback to the control box.
2). The control box is damaged.
3). The oil pipe is blocked or there is water in the oil.
5. Adjustment of exhaust air duct with black smoke
1) The damper opens too narrow or there is resistance in the intake air inlet.
2) The atomization of the spray nozzle is in bad condition.
3) Adjustment between damper and burner is improper, and then the input air volume is too small.
4) Adjustment of air pressure is so high that the air can not be burnt sufficiently.
