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.
