Suction Relief Valve

Regenerative Suction Pumps cannot be allowed to run sealed, without a minimum of 150 CFM or the fan may be damaged.

1. DRV330 suction relief valve is installed in the intake line following the dirt cans and just before the motor
2. Relief comes pre-set from the factory. Installers shall test the valve according to the installation manual and confirm correct operation and suction relief.

 

 Power Unit installation

1. Location

The VacuMaid power unit system should be installed in area with ventilation and a solid cement floor.  The unit must be exhausted to the outside with 3-1/2” metal piping not to exceed 20 ft in length.  Area should be large enough for mounting of the suction relief valve and servicing the two dirt canisters.

 

1. Pump and Canisters

The CR1500 pump should be mounted on a solid surface that will not increase or transmit vibration or sound.  Vibration isolation materials are recommended.  3-1/2” steel pipe with long radius elbows are recommended.  PVC Schedule 40 is an acceptable alternative for the intake, steel pipe is required for the exhaust

1. Electrical Control Box

CP1500 control box should be mounted on a wall close to the pump.  Electrical Service of the chosen voltage is fed into the control box.  24 Volt remote control wires from intake piping system are fed into the control box.

 

1.4 Piping and Valves.

1. Pipe or Tube

VacuMaid recommends steel pipe for commercial systems.

1. Trunk line, Canisters, Pump and exhaust; 3-1/2” OD with long radius sweep elbows
2. Transitions and drops to the valves: 2-1/8” OD with long radius sweep elbows and Tee’s
3. Exhaust pipes are required to be in 3-1/2” steel
4. Steel Valve mount plates part # SF395 with Aluminum tight 90 Ells part # AF210B for 1-1/2”

inlet valves.  Mount plates are fastened to partition wall studs in determined locations

1. Stainless steel inlet valves for 1-1/2” hoses with Micro-Switch remote control switches

Part number WS832X.  Note:   The thickness of the wall IE: sheet rock and / or wainscoting must be known to determine

The length of the valve stem.

1. Steel pipe couplings and fittings should be connected with “PlioBond” brand cement.

 

Remote Control Wiring

Inlet Valves

VacuMaid Commercial Systems have a 24 volt on/off remote control system incorporated into the electrical control box.

All inlet valves have a microswitch to control the on/off function.  Switch is closed when the hose cuff is inserted into the inlet valve.

1. Low volt control circuit is wired to every valve in one looped run and fed into the control box
2. Common or Plenum Rated 18/2 multi strand wiring is used.
3. Low Volt wire is Zip Tied to the pipe

 

Cleaning Attachments (purchased separately)

Hose

Hose should be commercial grade 1-1/2” OD with a soft cuff on the valve end and curved steel end for the cleaning end.

Curved hose wand on cleaning end has 1-1/4” diameter.

1. Wands

Two steel 1-1/4” steel wands for each hose

1. Attachments

Commercial grade, 1/1/4” Floor Tool, Carpet Tool, Duster Brush, Upholstery Tool, Crevice Tool.

 

Installation Services

All central vacuum systems are dependent upon a correct and proper installation.  Lindsay Mfg Inc can recommend competent and experienced sub-contractors for this work.
