SAFETY CONSIDERATIONS
Installing, starting up, and servicing ventilation equipment
can be hazardous due to system pressures, electrical compo-
nents and equipment location (roofs, elevated structures, etc.).
Only trained, qualified installers and service mechanics should
install, start up, and service this equipment.
When working on the equipment, observe precautions in the
literature and on tags, stickers, and labels attached to the
equipment. Follow all safety codes.

Before installation, always check to be sure main power to
systems are OFF. Electrical shock can cause personal
injury or death.
GENERAL
The P707-SHR1504 and P707-SHR2004 Heat Recovery
Ventilators (HRV) are used to exchange indoor stale air with
outside fresh air. The HRV unit is equipped with a special ener-
gy recovery core which transfers sensible heat with the fresh
incoming air. The cross-flow design core allows entering and
leaving airstreams to transfer heat energy without mixing.
The HRV is available in 2 sizes with airflow ranges of
150 cfm (SHR1504), and 200 cfm (SHR2004). The design of
this unit is horizontal. Special attention should be given to duct
application, balancing the HRV, and locating unit for easy
access and routine maintenance. See Table 1 and Fig. 1 for
performance data.

Page 2: Installation
INSTALLATION Step 1 — Unit Location — The HRV must be located in a heated space where it can be conveniently serviced. Typically the HRV is located in the mechanical room or an area close to the outside wall where the weather hoods will be mounted. -
Page 3: Step 3 - Install Drain Line
Step 3 — Install Drain Line — Through normal op- eration and during defrost mode, the HRV may produce some condensation. This water should be directed to flow into a nearby drain, or be removed by a condensate pump. The HRV and all condensate lines must be installed in a space where the temperature is maintained above the freezing point. -
Page 4: Step 6 - Install Indoor Ductwork System
Direct Connection — A direct connection requires that the furnace fan run continuously. See Fig. 13. The fan may be inter-linked electrically (low voltage) with the HRV accessory control contacts for intermittent demand. To hard duct the supply air directly into the cold air return of the furnace, remember to check the airflow balance of the HRV with the furnace fan both on and off to determine that it does not imbalance the HRV more than 10%. -

INSTALLATION EXAMPLES — It is the responsibility of Fully Dedicated System (New Construction) — Stale air is the installer to ensure all ductwork is sized and installed as drawn from key areas of home (bathroom, kitchen, laundry). designed to ensure the system will perform as intended. All air Fresh air is supplied to main living areas. -

Page 11: Continuous/Ventilation Mode
CONTINUOUS/VENTILATION MODE — In this mode of operation, both fans are operating and exchanging air with the AIR FROM AIR FROM outside. The heat recovery ventilator constantly exchanges the OUTSIDE HOUSE air at the selected rate, either at low or medium speed, and switches to high speed when activated by an accessory remote control. -

TROUBLESHOOTING See Table 2 for troubleshooting. Table 2 — Troubleshooting PROBLEM CAUSE SOLUTION Air is Too Dry Dehumidistat control is set too low. Increase the desired level of humidity. Change ventilation mode from continuous mode to standby. HRV out of balance. Balance HRV. - Page 13 HEAT RECOVERY VENTILATORS LIMITED 5 YEAR WARRANTY — PARTS 7 YEAR WARRANTY — MOTOR LIFETIME WARRANTY — CORE MULTI-YEAR WARRANTY — This CARRIER CORPORATION product is warranted to be free from defects in material and workmanship under normal use and maintenance for a period of 5 years for parts, 7 years for the motor, and a lifetime warranty for the core from the date of original installation.
