Frigate HRV(ERV) 120 S This installation example is applicable only for Vents Frigate ERV 120 S Fig. 4. Wall unit mounting CONDENSATE DRAINAGE The Vents Frigate HRV 120 S unit is equipped with a condensate drain hose for condensate drainage (fig. 5). Connect the drain hose (1), U-trap (3) and drain system (5) with metal, plastic or rubber pipes (2 and 4). The pipes must be sloped down at least by 3°.
Connection to power mains Cut power supply off before any operations with the unit. The unit shall be connected to power mains by a duly qualified electrician only. Rated values of the electrical parameters are shown on the rating plate. Any modifications of the internal connections are not allowed and will void the warranty. The unit is designed for connection to single-phase ac 120 V / 60 Hz power mains.
Frigate HRV(ERV) 120 S UNIT CONTROL The unit is controlled by a three-position speed switch that enables low-speed modes «Low» and «Med» as well as «Stand by» mode which enables total air quality control (fig. 7). Up to five external control devices may be connected to the terminals 2-11 that turn the unit to high-speed ventilation in case of activation of any of the control devices (fig. 6). Terminals for connection of the remote control panel Three-speed switch Fig. 7.

If the indoor humidity exceeds the setpoint, the humidistat switches the ventilation to high-speed mode. The unit operates in highspeed mode until humidity drops to setpoint. Adjust the humidity setpoint if required. Check that the humidistat closes contact if indoor humidity exceeds the setpoint and breaks contact if the indoor humidity is below the setpoint.
4. Mechanical timer The remote mechanical timer (fig. 11) is designed for installation in pollutable areas. As the timer is activated the unit is switched to high-speed mode. You can connect up to 5 timers in the premise at 500 feet (152 m) distance to the unit. OFF 60 10 50 20 40 Fig. 11. Mechanical timer 5.

SERVICING AND MAINTENANCE Servicing of the unit is required 3-4 times per year. Besides general cleaning, the following operations are required: 1. Filter maintenance (3-4 times per year) Dirty filters increase air resistance in the system and reduce supply air flow to the premises. Clean or replace the filters as often as required, but at least 3-4 times per year. Clean the filter with running water or a vacuum cleaner. After two cleaning replace the filter.
Frigate HRV(ERV) 120 S Troubleshooting Possible malfunctions and fault handling Problem Possible reasons Power supply is off. The fan(s) do(es) not start running. Thermal fuse is melted. The extract filter is clogged. Cold supply air. The heat recovery core is frozen. Too low set rotation speed. The filters, fans or heat recovery core are clogged. Low air capacity. The ventilation system is clogged or damaged. The impeller(s) is (are) clogged. Noise, vibration.
STORAGE AND TRANSPORTATION RULES Store the unit in the manufacturer’s original packing box in a ventilation premise with the temperature range from +14 °F (-10 °С) up to +104 °F (+40 °С) and relative humidity less than 60% (at +68 °F (+20 °С)). Vapors or particles which can cause corrosion or damage the insulation or connection tightness are not allowed in the stock. Use hoist equipment for loading and storage operations to prevent the unit falling or excessive oscillation.
