System Location - RadonAway AIRaider 433-S50 Instruction & Installation Manual

2.1. System Location

When selecting the location for the AIRaider
1. System Plumbing Hook-up. Find a location that will minimize the amount of plumbing
necessary, this is typically in proximity to the well tank.
2. Electrical Hook-up. Keep in mind the need for accessibility to a 20 Amp dedicated 120VAC
power supply or 30 Amp dedicated 230VAC for 230V 433 Systems.
3. Exhaust Line Venting. The location of the system must allow for outside venting of the
system exhaust above the eave of the structure. The manufacturer requires that the exhaust
pipe pitch back toward the system (see Section 2.6).
4. Remote Air Intake. If the system must be installed in an area with questionable air quality
(i.e. furnace room, garage, crawl space) then ducting from the air intake to a remote location
having good air quality may be required.
5. System Must Be Level. The system should not be located on a significant slope as this may
impede system performance.
Place the system in the location acceptable to customer that maximizes the ease of installation.
All Local and State codes as well as any applicable AARST, EPA and/or State Radon standards must
be adhered to when locating the AIRaider
2.2. Readying the AIRaider
For 433 and 321 systems (433 Illustrated). This section does not apply to Systems with integral pumps (433-S50 & 433-S50X Systems).
1. If using the Grundfos MQ3-45 Pump attach Mount-
ing Bracket to wall as shown in Fig. 3 (page 8). Note
bracket hole height is specific to the Grundfos MQ3-
45. If using a different pump adjust bracket height as
required to place pump suction pipe centerline at the
system outlet centerline as specified in Fig. 3.
Note: Short horizontal pipe run from system outlet to pump inlet is optimal. If this
pump location is impractical because of space constraints the pump may be located
remotely at a higher location, but pump lift, pipe diameter, and equivalent pipe length
must comply with limits specified in the pump installation instructions.
Do not mount pump lower than shown as removal of the pump for
service may result in tank contents siphoning out onto the floor!
2. Install the Suction Check Valve provided with the
Grundfos MQ3 Pump into the pump inlet as shown in
the pump installation instructions. This will prevent
loss of pump prime and possible interruptions in the
water supply to the house. Remove the priming plug
from the pump and add the specified volume (See
Pump Installation Instructions) of water to the pump.
Either re-install the priming plug or install a ⅜" NPT
x 2" long pipe nipple and attach a ¼" NPT Pressure Gauge
with with ¼" x ⅜" FNPT Reducer to the pipe nipple (Fig. 2).
