Multiquip MQD2H ユーザーズマニュアル

1.

Read safety instructions at the
beginning of manual.

2. Place pump as near to water as

possible, on a firm flat, level surface.

Suction and discharge hoses are
available from Multiquip. Contact
your nearest dealer for more
information.

4.

The discharge hose is usually a 

collapsible  (thin-walled)

hose, however if a thin-walled discharge hose is not avail-
able, a rigid suction hose can be substituted in its place.

5.

Make sure  the

 suction strainer  (Figure 2) is clean and

securely attached to the water end of the suction hose. The
strainer is designed to protect the pump by preventing large
objects from being pulled into the pump.

DO NOT open

 fill cap if pump is hot! Water inside may

be under pressure.

1. Check that all hoses are

 securely attached to the pump.

Make certain suction hose (Figure 2) does not have any air
leakage. Use teflon tape or pipe dope on NPT threads.

2. Remember suction hoses must be 

rigid  enough not to

collapse when the pump is in operation.

3.

Check that

 the discharge hose (Figure 2) is not restricted.

Place hose so that  it  lays as  straight as it is possible on the
ground. Remove any twists or sharp bends from hose which
may block the flow of water.

ALWAYS wear approved eye and hearing
protection before operating the pump.

NEVER operate the pump in a confined
area or enclosed area structure that does
not provide ample 

free flow of air.

The MQ-D2H/D3H diaphragm pumps are completely
assembled except for the steering handle. Attach the steering
handle to the pump base as shown in Figure 6.
