Installation Date
NOTE: ALTHOUGH SOME MODELS
DIFFER IN OPERATION, THE BASIC
STEPS ARE SIMILAR.
CAUTION
Before installation, careful consideration must be
given to how the system will operate if connected to
any other piece of mechanical equipment, i.e. a forced
air furnace or air handler, operating at a higher static.
After installation, the compatibility of the two pieces of
equipment must be confirmed, by measuring the
airflow's of the Heat/Energy Recovery Ventilator
(HRV), by using the balancing procedure in
this manual.
It is always important to assess how the operation
of any HRV may interact with vented combustion
equipment (ie. Gas Furnaces, Oil Furnaces, Wood
Stoves, etc.).
NEVER install an HRV in a situation where its normal
operation, lack of operation or partial failure may result
in the backdrafting or improper functioning of vented
combustion equipment!!!

Page 6: Sizing Your Pool Hrv
Sizing your Pool Heat Recovery Ventilator Determining ventilation requirements for Indoor Pool enclosures There are two primary reasons to ventilate an indoor pool enclosure. One is to provide effective and efficient control of harmful humidity levels. The other reason is to control the Indoor Air Quality (IAQ) in the pool room enclosure. -
Page 7: Calculation
Calculation Note: As a general rule, if the water temperature is maintained at 80˚F and the pool room air temperature is maintained at 82˚F, use a factor of 1 cfm/sq ft of pool surface or .5 cfm/sq ft of room area (whichever is greater) to determine amount of ventilation required. - Page 8 TABLE 1 40% 50% 60% 40% 50% 60% 40% 50% 60% 40% 50% 60% 40% 50% 60% 40% 50% 60% 0.069 0.063 0.056 0.079 0.073 0.066 0.090 0.084 0.077 0.102 0.095 0.089 0.115 0.108 0.102 0.068 0.060 0.053 0.078 0.070 0.063 0.088 0.081 0.074 0.100 0.093 0.086 0.113 0.106 0.099 0.065 0.058 0.050 0.075 0.068 0.060 0.086 0.079 0.071 0.098 0.090 0.083 0.111 0.103 0.096 0.125 0.063 0.055 0.047 0.073 0.065 0.057 0.084 0.076 0.068 0.096 0.088 0.079 0.109 0.101 0.092 0.123 0.061 0.052 0.043 0.071 0.062 0.053 0.082 0.073 0.064 0.094 0.085 0.076 0.107 0.098 0.089 0.121 0.112...

Page 12: Location For Mounting
Location for Mounting The HRV must be located in a heated space where the surrounding air temperature does not fall below 60˚F (16˚C). The unit must be mounted level (horizontal) to obtain proper drainage or water from the heat exchange element and drip pans. -
Page 13: Outside Weatherhoods
Outside Weatherhoods The weatherhoods must have built-in “bird” screen with 1/4 in (6.35 mm) minimum mesh to prevent birds and rodents from entering into the ductwork. Do not use smaller mesh as it will be very susceptible to plugging up. Gravity dampers at the vents must not be used as they will restrict air flow and often “seize up”. -
Page 14: Fresh Air Supply System
Fresh Air Supply System The fresh air supply ductwork from the HRV may be directly connected to the return air duct of the forced air system. Check the air flow balance of the HRV with the air handler blower both “ON” and “OFF” to determine that it does not imbalance the HRV more than 10%. -

Page 16: Electrical Connections
Electrical Connections It is recommended that a licensed electrician make all electrical connections. It is very important that the unit be properly grounded. It is recommended that a separate 15 amp/120 volt circuit be used. WARNING: In order to prevent electric shock when cleaning or servicing the HRV, it is extremely important to confirm the polarity of the power line that is switched by the safety (disconnect) switch whose control arm is... -
Page 17: Operation Of The Hrv
Operation of the HRV These Recirculating Models of HRV's will provide fresh clean air without sacrificing the savings of your energy conserving home. When outdoor air is required for pool room dehumidification, the aluminum cores of the HRV provide effective and efficient heat recovery exchange. Whether operating as an HRV or in recirculation mode, the energy efficient PSC blower motors provide reliable and cost effective operation. -
Page 18: Ducting Requirements & Mode Of Operation
Ducting Requirements & Mode of Operation Ventilation Mode In ventilation mode, both motors are running and air is being exchanged with the outside through the supply and exhaust ducts. Recirculation Mode In recirculation mode the supply motor continues to run and a damper moves to block off air entering from outside, drawing air instead from the conditioned space. -
Page 19: Speed Selection And Controls
Ventilation/Recirculation Damper only, not low/high speed control. DISCLAIMER The Model 1000RHC and RHCAC is intended to be installed by certified HVAC trades people. Damage resulting in partial or complete failure of the Reheat/Air Conditioning portion is the respon- sibility of the installing contractor. -

Page 21: Service/Maintenance
Service/Maintenance Servicing your HRV on a regular schedule will result in optimum operating efficiencies and prolonged life of the equipment. Due to numerous applications in which this equipment can be installed, it is difficult to predict servicing intervals. In certain situations where there is heavy smoke, servicing the equipment every one - two months may be needed;... -
