903106-UTG-A-0912 MAXA-MI$ER® TECHNICAL GUIDE V* Series Unitized Energy Recovery Ventilators ERV Unit with 3 - 12.5 Ton Packaged Unit DESCRIPTION • Reduces cooling load at design temperatures up to 4 tons per 1000 cfm of outside air. • Reduces heating load up to 2.5 Tons Btuh per 1000 CFM of outside air. • Dry energy transfer. Moisture in supply (intake) air stream is transferred to exhaust air stream in a vapor state, eliminating condensate plumbing from the UERV.

903106-UTG-A-0912 APPLICATIONS Critical Terms for Standard 1060 are as follows: Unitized Energy Recovery Ventilators (UERV) are used with the UPG rooftop packaged units. The internal wheel provides sensible and latent energy exchange between the entering and exhaust air streams of a building. This allows a substantial amount of the energy, which is normally lost in the exhaust air stream to be returned into the entering air.
903106-UTG-A-0912 CROSS LEAKAGE IN UERV’S (PURGE SECTORS) The issue of cross leakage in rotary wheel based UERV's used in space conditioning applications is often misunderstood. As a result, many systems are installed with purge sectors and the additional fan capacity required to allow these sectors to function when in fact they are unnecessary.
903106-UTG-A-0912 OPTIONAL ACCESSORIES - FACTORY INSTALLED L6 - LAK, SSJ, and PS L7 - LAK and PS L8 - LAK, MOA, and PS Low Ambient Control Kit - Prevents frost formation on energy wheel heat transfer surfaces by terminating the intake blower operation when discharge air temperature falls below a field selectable temperature setting. Intake blower operation resumes operation after temperature rises above the adjustable temperature differential.

903106-UTG-A-0912 GUIDE SPECIFICATIONS Prepared for the guidance of architects, consulting engineers, and mechanical contractors. GENERAL Furnish and install _____________ mechanical cooling system, complete with a Unitized Energy Recovery Ventilator (UERV). APPROVALS The Unitized Energy Recovery Ventilator will contain an energy recovery component rated in accordance with AHRI/ ANSI Standard 1060-2005 with ratings certified by AHRI.
903106-UTG-A-0912 OPTIONS 2. The ERV is activated with the supply blower of the RTU. The intake blower, the exhaust blower, and the wheel rotation motor of the ERV are activated. These motors will remain energized as long as the supply blower on the RTU is energized and the RTU is in standard (noneconomizer) mode. 3. If the optional motorized fresh air damper in the outside air intake of the ERV is present, it opens and the ERV is energized. 4.
903106-UTG-A-0912 UERV TROUBLESHOOTING GUIDE UERV BELOW 600 CFM WITH STATIONARY WHEEL (NO ECONOMIZER) 4. If all of the above are operational, the exhaust motor is bad. Replace it with new motor. UERV will not operate. UERV has power, but the fresh air blower does not operate. 1. 1. Verify the A130 circuit board switch SW1 Power is in the "on" position. 2.
903106-UTG-A-0912 control, etc.). Typically, "1" would be from the blower contactor on an a/c unit. 2. Verify high voltage power to UERV. a. b. tactor terminal "A" and "B", and that the contacts are closed. 3. Check for correct voltage for UERV to L1 and L2 on 1-phase units. Verify power to B27 fresh air blower motor though J/ P148 plug assembly. 4. Check for correct voltage for UERV to L1, L2, and L3 on 3-phase units. On direct drive models, verify B27 wheel motor C26 capacitor is good.
b. Check for correct voltage to L1, L2, and L3 on 3phase units. c. Verify the F29 fuses are good. Replace any bad fuses. c. Verify power to B27 fresh air blower motor though J/ P148 plug assembly. d. Verify that the T27 transformer has the UERV voltage correctly applied to the correct transformer terminals. d. On units equipped with the optional low ambient control, verify that the circuit on the A130 circuit board terminal "5" and "6" is made.
