GNRL GNRL INFORMTION The ventilator should only be installed by a trained heating and air conditioning technician. These instructions serve as a guide to the technician installing the ventilator package. They are not intended as a step by step procedure with which the mechanically inclined owner can install the package. The ventilator housing is shipped in one carton which contains the electrical harness, miscellaneous hardware and installation instructions. UNPKING Upon receipt of the equipment be sure to compare the model number found on the shipping label with the accessory identification information on the ordering and shipping document to verify that the correct accessory has been shipped. Inspect the carton housing of each ventilator as it is received, and before signing the freight bill, verify that all items have been received and that there is no visible damage. Note any shortages or damage on all copies of the freight bill. The receiving party must contact the last carrier immediately, preferably in writing, requesting inspection by the carrier s agent. oncealed damage not discovered until after loading must be reported to the carrier within 15 days of its receipt. SRIPTION The RV-5 ventilator is designed to be used with ard 3-1/2 thru 5 ton wall mount series air conditioners and heat pumps. They are electromechanical vent systems designed to provide fresh air to meet indoor air quality standards with built in exhaust provisions. INSTLLTION SI INSTLLTION 1. Unpack the ventilator assembly which includes the integral ventilator with attached electrical harness and miscellaneous hardware. WRNING Open and lock unit disconnect switch before installing this accessory to prevent injury or death due to electrical shock or contact with moving parts. Turn thermostat to off.

2. Remove and save the existing exterior blower access and service access panels on the ard wall mount unit. (See Figure 1.) FIGUR 1 RMOV SS PNLS MIS-425 Page 2
3. Remove and save existing unit air filter and screws from front center grille. (See Figure 2.) 4. Remove and discard the exhaust cover plate. FIGUR 2 RMOV IR FILTR N XHUST OVR PLT MIS-427 Page 3
5. For Installation of Left Hand Units Only Remove strain relief in right side of RV. Un-clip the (2) wire ties holding the wire harness. Reroute wires to left side of RV. Reinstall wire ties in left side holes. Route wires through left side and reinstall strain relief. (See Figure 3.) FIGUR 3 RROUT WIRS FOR LFT HN UNITS ONLY MIS-1334 Page 4
6. Install ventilator by inserting the ventilator into the unit to the far left side clearing the right filter bracket. Once the ventilator is fully inserted, slide the ventilator to the right until it is tight against the back of the control panel. (See Figure 4.) IMPORTNT: front lip of ventilator on top of front grille and condenser partition. (See Figure 4 inset.) This is important to ensure proper drainage of any water entering damper assembly. 7. Open control panel to gain access to unit low voltage terminal block. 8. Route electrical harness leads through the 7/8 bushing in control panel (Figure 4) into low voltage box.

Resupply power to unit.. nergize the evaporator blower by switching thermostat to the manual fan position with heat/cool in OFF position.. Ventilator should open to the position set by position adjustment thumbwheel. ycle position adjustment thumbwheel to full open through full close. Observe damper blade operation throughout travel to assure free, unobstructed movement. (See Figure 5.). djust position adjustment thumbwheel until desired blade setting is reached with power applied to unit. See Tables 1 through 3 for required blade setting versus ventilator air. F. e-energize evaporator blower. amper blade should close. G. This completes ventilator checkout. 14. Replace mist eliminator. e sure it is installed with the drain holes to the bottom. 15. Remove blank off plate or barometric fresh air damper installed on service access door. Plug four (4) mounting holes with the plastic plugs provided with the ventilator. 16. Replace service access panel. 17. Ventilator is now ready for operation. L JUSTMNT FOR SIR VNTILTOR IR The amount of ventilation air supplied by the commercial room ventilator is dependant on four (4) factors. 1. Return air duct static pressure drop. 2. Supply air duct static pressure drop. 3. Indoor blower motor speed. 4. amper blade open position setting. To determine the amount of fresh air that will be supplied to the structure first determine the pressure drops of the supply and return air ducts. For free blow application with return air filter grille and supply grille assume.05 supply static,.10 return static. See application Table 3. etermine on what speed the evaporator motor is running. Refer to the tables on the following pages to determine the blade setting necessary to achieve the ventilation air requited at the supply and return static duct pressures drops that are applicable.
