Installation Instructions

for HS  &  HSE Power Roof Ventilators 

 

Pre-Installation Check of PRV.   Before installation 

of an American Coolair PRV, a careful check should be made 

for shipping damage which may affect operation of the unit. 

Concealed damage to the wind shroud damper assembly is a 

possibility. If damage is found, file a claim immediately with 

delivering carrier. On belt drive units, pulley alignment and 

belt tension should be checked (see paragraph 2 under 

Operation and Maintenance). Before connecting to power 

source, make sure propeller turns freely without striking 

frame or any foreign object. Check motor nameplate to be 

sure correct phase and voltage are being used. Note 

direction arrow adjacent to propeller and make sure rotation 

is correct when power is applied.

 

Installation Procedures.   Types HS / HSE PRV are 

shipped in two packages for quick assembly and installation 

on roof curb.

a) Installation of Base of PRV.    The major component of the 

Type HS / HSE PRV is the base section made up of curb cap, 

fan and motor. Verify curb dimensions and securely attach 

base to curb.

b) Installation of Wind Shroud Assembly.    The wind shroud 

assembly consists of wind shroud and counterbalanced 

dampers. Wind shroud assembly should be attached to 

shroud supports on base of PRV. Bolts for this purpose are in 

a bag tied to the damper stop inside the wind shroud. Metal 

clips holding dampers in closed position for shipment 

should be removed and discarded. Manually operate 

dampers to be sure they open freely and close snugly over 

inner ring of shroud.

c) Magnetic Latches (Optional Accessory).    If magnetic 

latches are provided, check adjustment of latches to insure 

proper contact with butterfly damper when closed.

Note :  All local, state and federal codes should be checked to make 

sure all wiring, guarding and intended usage of the PRV unit(s) 

comply with all applicable codes. The proper type and class of PRV 

and motor should be used for air being handled such as explosive 

or other hazardous air mixtures.
