1. Setup

ØRemove the cover and orient the unit so the circulation vents face one of the HVAC attachment points on your shelter. Locate the unit on solid, level ground, using shoring or a plywood base if necessary.

ØNote: The main power cables and thermostat are routed around the back of the unit. The 30-Amp cable can attach to either an electrical distribution box or directly to a generator with a 30-Amp, 208/240V output.

D. OPERATING INSTRUCTIONS

ØNote: In the green vinyl pouch on the rear of the unit, you will find the thermostat with 50 foot cable, operations manuals, and a hex driver for unit maintenance.

ØThe HVAC unit attaches to any of the duct boot openings around any WSS shelter. To eliminate trip hazard, it is recommended that the HVAC unit be positioned away from the most used doorways if possible.

ØTo access the panels, remove the square vinyl covers from both ports, and the square insulation panels, if installed. They can be stored in the duct-boot bag on the HVAC unit so they will not be misplaced.

ØIf you are using an air plenum, install it now.

See documentation accompanying the air plenum for installation information.

ØIn the side pouch are the two duct boots for attaching the HVAC unit to your shelter. The tapered boot attaches to the top of the unit, and the re-enforced boot with filter screen attaches to the bottom. Also in the pouch is the p-trap for condensation discharge.

ØAttach the duct boots to the shelter. The angled boot goes on top, and the re-enforced boot underneath.

ØTo attach the unit, align it with the duct boot openings, about two feet from the shelter wall.

ØAttach the duct boots to the HVAC unit with the black nylon straps. Place the lower duct boot over the lower port, then snug the strap tight. Be sure the seal is tight all around. Repeat on the top port. Move the unit back a few inches to put some tension on the boots so air will flow easily. Lock the wheels.

Be sure you have read and understood all safety warnings before attempting to operate this unit.

ØAttach the p-trap by filling it with water, capping one end with your hand, and firmly push the non-threaded end into the drain.

A standard garden hose can be attached to drain water away from the shelter base.

ØUnwrap and install the thermostat. Make a small opening in the bottom of the upper duct opening and pass the thermostat through, along with 50’ of cable.

ØInside the shelter, string the cable over roof trusses until it is located on the opposite side of the shelter from the ducting. This results in a more accurate reading of the shelter temperature.

ØSecure the thermostat about six feet off the ground.

2. Operation

ØCAUTION: Be sure the green vinyl bags are away from air intakes when the unit is operational

ØIf you are drawing power directly from a generator, attach the power cable from the HVAC system to your generator. Generator operation is not covered in this manual, and should be performed by a trained individual. You can also attach the system to an electrical distribution box. The main power connects to a 30-Amp outlet, and the emergency heating to a 50-Amp outlet.

ØOnce the system is connected and the power is running to the unit, set the desired temperature and system mode on the thermostat. The unit is designed not to change modes more than once every three minutes, so it may take up to three minutes for the HVAC unit to begin operating.

ØThe thermostat has very simple controls.

The “SYSTEM” button switches between cool, heat, emergency heat and off. The fan can be switched to either Auto or On position and programmed with a 90 second Off-delay. To adjust the Off-delay see page 7.

The up and down buttons set the desired temperature. The system is designed to go into emergency heating mode, if available, when the ambient temperature is at least six degrees cooler than the temperature set on the thermostat.

3. Emergency heat

ØThe emergency heat connection, if included on you unit, can be located under the small panel above the “emergency heat power” notice. This connection will boost the heating power of the unit by 11,000 BTUs/hr, and requires a 50-Amp, 240 volt connection. The connection draws 42 Amps continuously when operating, so plan your power distribution accordingly. When operating in conditions under 40 degrees, the emergency heat is recommended to keep the unit running well.

4. Switching operation voltage

ØThe HVAC unit is capable of running off either 208 or 240 volts, depending on your electrical setup. Do not change modes without a solid understanding of your electrical distribution setup. Do not run the HVAC unit until it is properly setup up for your system.

ØTo change between 208 volt and 240 volt operation, detach the panel with shock hazard warnings located next to where the power cables come out of the unit.

ØLocate the red wire with white clip running to a transformer with two leads. The leads are printed “208” and “240.” When using a single-phase generator, connect to the 240 volt connection. When using three-phase generator, connect to the 208 volt connection. The unit comes preset to the 208 volt connection, unless otherwise noted on label.

3. Professional service checklist

ØTo keep your unit operating as designed, a qualified serviceman should check over the entire system at least once each year as well as any other time that you feel that service is needed. Your serviceman should examine and inspect:

•Filters (for cleaning or replacement)

•Motors and drive system components

•Condenser coils (for cleaning)

•Safety controls (for mechanical cleaning)

•Electrical components and wiring (for possible replacement and connection tightness)

•Condensate drain (for cleaning)

•Unit duct connections to see that they are physically sound and sealed to the unit casing

•Unit mounting support to see that it is sound

•Unit to see that there is no obvious unit deterioration.

E. MAINTENANCE / TROUBLESHOOTING

ØYou can do some of the periodic maintenance functions for your XE1200 unit yourself. These functions include replacing the disposable or cleaning the permanent air filters, cleaning the unit’s cabinet, cleaning the condenser coil, and conducting a general inspection of the unit on a regular basis.

1. Replacing the air filter

ØIt is very important to keep the duct system air filters clean. Be sure to inspect them at least once each week when the system is in constant operation.

ØReplace used filters with new filters of the same type and size. Do not try to clean disposable filters.

ØLocated on the front side of the unit are the discharge and return ports. The air return port uses a filter similar to most home systems (16x25x1), and can easily be replaced.

ØTo replace the air filter, unscrew the four hex screws securing the front port cover.

Inside the cover is the air filter. Pull up on the filter, then out on the bottom to remove.

Place a new filter in top end first and push up to fit into place.

2. Cleaning outdoor coil

ØWith the front cover off, you can see the heating and cooling elements. They should be free from dust and debris.

ØUnfiltered air circulated through the unit’s outdoor coil can cause the coil’s surface to become clogged with dust, dirt, etc. To clean the coil, stroke the coil surface with a soft-bristled brush vertically, that is, in the direction of the fins.

4. Troubleshooting check list

•Is the unit properly and securely located and level with the proper clearance?

•Is the duct work correctly run with the proper unit arrangement?

•Is the condensate line properly run? Does it drain freely?

•Is the filter of the correct size and number? Are the supply and return ports unobstructed?

•Is the power supply correct for the unit’s requirements?

•Are all wiring connections, including those in the unit itself, tight?

•Is the thermostat well located and accurately adjusted?

•Do the outdoor fan and the indoor fan turn free without rubbing? Are both fans tight on their shafts?

•Are all cover and access panels in place to prevent air loss and to protect against safety hazards?

•Have all tools and debris around, on top of, and under the unit been removed?

5. Resetting the thermostat

ØIt may become necessary to reset the unit thermostat. If the thermostat has lost power or is not operating properly, follow these steps to reset it.

ØReplace the AA batteries in the thermostat.

ØPress and hold the UP and FAN buttons until the unit display changes to settings mode.

ØPress the UP and DOWN buttons to change settings.
