Position the hoisting eyes on corners of the unit with the angle towards the center of the unit. (See illustration at right) Run the bolt through the unit housing and hoisting eye, then attach the nut. (See illustration at right). DUCTWORK 1. Sizing and layout of ductwork and outlets should provide maximum uniform airflow throughout the area. Make-up air should be introduced at a location inside the area, but as far away from existing exhaust hoods as possible to permit conditioned air to flow throughout the entire area before reaching the exhaust zone, or unless connected to an engineered make-up air system. 2. Ductwork must be adequately sized and designed for minimum resistance (static pressure) to provide required airflow. Check rating plate for minimum allowable CFM flow over the heat exchange: at low heating speed. 3. To avoid pressure losses, all short radius rectangular elbows should have turning vanes, offsets should not be avoided, and small ducts and takeoffs should be undersized. 4. Main supply duct normally consists of a rectangular vane elbow at the unit and vertical duct extension, both pieces having the same dimensions as the unit discharge opening. The ductwork gauge size must be according to local codes. Ceiling registers should be the fixed type (if adjustable, modify so full closing is not possible). (See illustration right) CEILING REGISTER With the make-up air unit in place on the floor, and the framed roof opening installed: 1. Position roof jack over the opening. 2. Caulk and attach the transition elbow to the unit with a flexible connection. 3. Push the extension duct up until it slides through the roof jack into the transition elbow (the bottom flange of the extension duct should fit flush with ceiling). 4. Seal, caulk and secure into place. 5. In the building, remove side grilles from the ceiling register box, center box over opening and secure. 6. Protect outdoor ductwork with weatherproof insulation material. 7. Any ductwork within 6 feet of unit must have a minimum of 2 inches clearance from combustible materials. 8. This is ARES recommendation but you should always check local codes in your area.

It then flows by gravity through “V” shaped slots and saturates the cooling filters. A float valve assembly replaces water lost by evaporation. To avoid build up of organic minerals and salts in the sump, an adjustable bleed-off valve directs a small stream of water through the overflow drain. An optional fill and drain kit, which consists of a 3-way valve, 2-way valve and relay itemized for freeze protection of the Make-up Air Unit water line, is available for field installation. CAUTION: Damage caused by not correctly installing and servicing the bleed- off pipe is not covered by the ARES warranty. The following is a brief outline of the evaporative cooling installation procedure. 1. To install use an inside cold water line that has not passed through a water softening system because salts will create additional maintenance and upkeep. 2. Install a 1/2" water piping to the right front support leg of the unit. Include a convenient shut-off valve and provisions for draining to prevent freezing in the piping layout. 3. Install the overflow standpipe in the sump drain. 4. Install a drain line between the overflow standpipe (in the sump drain) to a suitable drain (check local codes). 5. Install the float valve assembly and adjust it so the water level is approximately 2" deep in the sump pan. (See illustration below). CAUTION: Damage caused by incorrect water level in sump pan is not covered by the ARES warranty. 6. Install the float valve and adjust the bleed valve to bypass the main water line to rid the system of organic and mineral deposits.

(See illustrations below) Packaged Hydronic/Steam Make-Up Air Unit Tel: (800) 421-1266 • Internet: www.marsair.com 10 OPERATION INITIAL START-UP 1. Check electrical power and manifold pressure against the unit’s nameplate. 2. Check airflow through the unit. a. The adjustable motor sheave should be adjusted to provide the correct blower wheel RPM to attain the design airflow at the inherent system resistance. Do not adjust sheaves so the airflow is below the minimum shown on the nameplate. b. Be certain the installation is adjusted to obtain the temperature rise specified on the nameplate. 3. Check belt tension and alignment. Correct tension is a center belt deflection of 1/2" and 3/4" for each foot of belt between the pulley and sheave. CAUTION: Never adjust the belt tension by changing the setting of the split motor sheave. Adjust by moving electric motor along tracks provided on the motor base to obtain correct fan belt deflection. 4. Check nameplate for maximum amperage. 5. With an observer at the unit, complete the following at the remote control panel: a. Assure power is on. Set unit on high speed (two speed units only). b. Push “Vent” button. Blower should operate. c. Using an ampmeter, test motor amperage and adjust as required with adjustable sheave. Be sure load on motor does not exceed nameplate amperage rating. d. Push “Cool” button. Pump and blower should be in operation. e. Push “Heat” button. The blower will remain in operation and the steam/liquid valve will be activated. f. On two speed models, place the 2-speed toggle switch in desired (high or low) position. g. Push “Off” button. Unit should shut down. 6. Check discharge air control for desired temperature setting. (Field provided on Hydronic units.) 7. If unit is operating properly, recheck system by repeating Step 5. If unit does not function properly, refer to Troubleshooting and Service Section. [...]...
