The Best
Limited Warranty
in the Business
• The heat recovery polypropylene core has
a limited lifetime warranty.
• The motors found in all Powrmatic HRV’s
require no lubrication, and are factory
balanced to prevent vibration and promote
silent operation.
• The limited warranty covers normal use.
It does not apply to any defects,
malfunctions or failures as a result of
improper installation, abuse, mishandling,
misapplication, fortuitous occurrence or
any other circumstances outside
Powrmatic’s control.
• Inappropriate installation or
maintenance may result in the
cancellation of the warranty.
• Any unauthorized work will result in
the cancellation of the warranty.
• Powrmatic is not responsible for any
incidental or consequential damages
incurred in the use of the ventilation system.
• Powrmatic is not responsible for providing
an authorized service centre near the
purchaser or in the general area.
• Powrmatic reserves the right to supply
refurbished parts as replacements.
• Transportation, removal and installation
fees are the responsibility of the purchaser.
• The purchaser is responsible to adhering
to all codes in effect in his area.
• The warranty is limited to 5 years on
parts and 7 years on the motor from the
date of purchase, including parts replaced
during this time period. If there is no
proof of purchase available, the date
associated with the serial number will be
used for the beginning of the warranty
period.
* This warranty is the exclusive and only
warranty in effect relative to the ventilation
system and all other warranties either
expressed or implied are invalid.
Sizing (Example) for maximum airflow normally required.
HRVs are typically sized to ventilate the whole house at a minimum of 0.35 air changes per
hour. To calculate, simply take the square footage of the house (including basement) and multi-
ply by the height of the ceiling to get cubic volume. Then, divide by 60 and multiply by 0.35.
Example:
SQFT of House 1100
Basement 1100
Total SQFT 2200
Height of ceiling x 8
Cubic volume 17600
/ 60
Maximum airflow required (CFM) 293
x 0.35
103
* Always consult your local code for sizing requirements in your area.
Room classification Number of rooms CFM (L/s) CFM Required
Master bedroom x 20 cfm (10 l/s) =
Basement yes or no =
Bedrooms x 10 cfm (5 l/s) =
Living room x 10 cfm (5 l/s) =
Others x 10 cfm (5 l/s) =
Kitchen x 10 cfm (5 l/s) =
Bathroom x 10 cfm (5 l/s) =
Laundry room x 10 cfm (5 l/s) =
Utility room
x 10 cfm (5 l/s) =
Total Ventilation Requirements (add last column ) =
Alternate Method
if yes add 20 cfm / 10 l/s
if no = 0
1 cfm = 0.47189 l/s
1 l/s = 3.6 m
