DO Adhere to all National and Local Plumbing and Electrical Safety Codes.

DO Turn “off” incoming electrical service switches when servicing, installing, or repairing equipment.

DO Check that all flare fittings on the carbonation tank(s) are tight. This check should be performed with a

wrench to ensure a quality seal.

DO Inspect pressure on Regulators before starting up equipment.

DO Protect eyes when working around refrigerants.

DO Use caution when handling metal surface edges of all equipment.

DO Handle CO2 cylinders and gauges with care. Secure cylinders properly against abrasion.

DO Store CO2 cylinder(s) in well ventilated areas.

DO NOT Throw or drop a CO2 cylinder. Secure the cylinder(s) in an upright position with a chain.

Warning

FIG 1

Disconnect and lock out all electrical power sources before performing
service or maintenance on this machine - - except when electrical tests are
being performed by qualified service personnel.

Introduction

The following instructions cover the installation of a 120 VAC, 60 Hz (domestic). An appropriate 3-Wire power
receptacle must be located within 6 ft (1.8 m) of the Booster Kits.

NOTE: Do not plug in Booster Pump Module at this time.

Grounding instructions

The Multiplex Model WBK10 Water Booster Pump should be grounded. In the event of an electrical short circuit,
grounding reduces the risk of electric shock by providing an escape wire for the electrical current. This product is
equipped with a cord having a grounding wire with an appropriate grounding plug. The plug must be plugged into an
outlet that is properly installed and grounded in accordance with all local codes and ordinances.

RISK OF ELECTRIC SHOCK: This kit is supplied with a ground
conductor and grounding-type attachment plug (domestic only). To
reduce the risk of electric shock, be certain that it is connected only
to a properly grounded, grounding-type receptacle.

Check with a qualified electrician or serviceman if the grounding instructions are not completely understood, or if in doubt as to
whether the product is properly grounded. Do not modify the plug provided; if it will not fit the outlet, have the proper outlet
installed by a qualified electrician.

This product is for use with a 120 VAC, 60 Hz (Domestic). CSA requires that a switch be provided to disconnect both outlets
from the power supply (refer to figure 1).

Do not use an extension cord or an adapter plug with this equipment.

How to install the water booster pump to a wall

1. Locate the six (6) 5/16” lag screws and the mounting bracket.

2. Mount the J-channel to the wall using three (3) screws (provided).

NOTE: Screws must be located in a stud. If mounting to concrete wall, proper hardware (not provided) must be used.

3. Mount the booster Panel on the wall by raising the top of the panel over the J-channel. Place the panel against wall and
slide the panel down until is catches on the J-channel. Mount the bottom of the panel to the wall using the remaining two
(2) screws (refer to figure 2).

4. Attach a 1/2” ID water inlet line to the inlet fitting using the 1/2” flare elbow with nut, and clamp provided. Then attach
another 1/2” ID line to the Water Outlet using the remaining 1/2” flare elbow with nut, and clamp (refer to figure 2).

5. Turn “on” the main water supply to the booster assembly.

NOTE: Outlet pressure of this assembly is not regulated. A regulator may be required for certain applications.

6. Plug the power cord into the wall receptacle. The pump will not begin to run until low water pressure circuit times out.
When the pump cycles “off”, the gauge should read 85 psi (59 bar). Bleed off water flow until pressure drops to
approximately 65 psi (4.5 bar). The pump motor should begin to run, then turn “off” when pressure reaches 85 psi
(5.9 bar). If not, there are instructions on the inside of the pressure switch cover for pressure switch adjustment.

If the system has a plate Style Water Filter, it MUST be mounted to
the right-hand side.

1. Locate the mounting hardware supplied with the support stand: three (3) 1/4”-20 x 1/2” Carriage Bolts, two (2) 1/4”-20 x 1/
2” Hex screws (not supplied), five (5) 1/4”-20 locking nuts, and the J-Channel Mounting Plate, (supplied with the Water
Booster). The J-channel Mounting Plate will later be mounted to the Water Booster Pump.

2. With the hook end of the J-channel towards the floor, mount the channel to the top portion on the side of the stand.

3. Fasten the channel with three (3) 1/4”-20 x 1/2" Carriage bolts and 1/4"-20 locking nuts. Tighten all bolts completely.

4. Lifting the back edge of the panel above the channel and hooking it on the lower edge of the J-channel, place the Water
Booster Pump panel on the J-channel.

5. Attach the lower edge of the Water Booster Pump panel to the channel on the support stand with two (2) 1/4”-20 x 1/2”
Hex screws and 1/4”-20 locking nuts. Tighten the screws and nuts completely.

6. Complete the remaining installation using the instructions supplied with the Water Booster Pump.
