GENERAL Greenheck Energy Recovery units with Te mpering are thor oughly inspected and test run at the factory . However , damage may occur during handling and shipping. Consequently , it is important to inspect the unit for visible and concealed damage before beginning installation.

1. Piping should be in accordance with accepted industry standards. Pipework should be supported independently of the coils. W ater connections are male NPT iron pipe. When installing couplings, do not apply undue stress to the connection extending through the unit.
8 ELECTRIC HEA TER APPLICA TION/OPERA TION Factory installed electric heaters can be provided for pr eheat and/or post-heat (see FIGURE 11). An electric preheater warms the outdoor air prior to the energy r ecovery wheel to prevent fr osting on the wheel.
FROST CONTROL APPLICA TION/OPERA TION DIRTY FIL TER SWITCH SETUP When outdoor air temperatures ar e extremely cold, moistur e condensation and frosting on the energy recovery wheel is possible. Frost contr ol is an optional feature that will pr event wheel frosting.
The energy recovery wheel may be de-energized for the purpose of pr oviding economizer (free cooling) operation. This can be achieved with a signal from a T emperature or Enthalpy sensor mounted in the supply air inlet compartment (see FIGURE 13).
11 GENERAL Check all fasteners and set screws for tightness. This is especially important for bearings and fan wheels. Also, if dampers are not motorized, check that they open and close without binding. F AN WHEEL ROT A TION Hand rotate the blower to ensur e that the wheel is not rubbing against the scroll.
12 ENERGY RECOVERY WHEEL CAUTION: See **W ARNING** on page 1 and 11 For the ERH-20 and ERH-45, open the access door marked "Energy Wheel Cassette Access". UNPLUG the wheel drive motor and remove the metal spacer . Then pull the cassette out halfway as seen in FIGURE 17.
13 ROUTINE MAINTENANCE CAUTION: See **W ARNING** on Page 1 and 11 Once the unit has been put into operation, a periodic maintenance program should be set up to pr eserve the r eliability and performance.
14 EXTERNAL FIL TER MAINTENANCE Aluminum mesh 2 in. filters are located in the supply weatherhood (if the weatherhood option was purchased). Filters should be checked and cleaned on a regular basis for best ef ficiency . The frequency of cleaning depends upon the cleanliness of the incoming air .
15 WA TER COIL MAINTENANCE CAUTION: See **W ARNING** on Page 1 and 11 FIL TERS Filters upstream of the coil should be checked r egularly . If the filters ar e dirty , they should be cleaned or r eplaced. It is important that the coils stay clean to maintain desir ed airflow .
FIGURE 20 For the ERH-20 and ERH-45, open the access door marked "Energy Wheel Cassette Access" (FIGURE 20). UNPLUG the wheel drive motor and remove the metal spacer . Then pull the cassette out halfway (FIGURE 21). The energy recovery wheel cassettes for model ERH-55 and ERH-90 do not slide out due to their size and weight.
CLEANING ENERGY RECOVERY WHEEL SEGMENTS If the wheel appears excessively dirty , it should be cleaned to ensur e maximum operating efficiency . Only excessive buildup of foreign material needs to be r emoved. DISCOLORA TION AND ST AINING OF ENERGY RECOVERY WHEEL DOES NOT AFFECT ITS PERFORMANCE.
