Equipment Service
Spencer provides prompt, courteous factory and field service
for all Power Mizer machines. To determine the nature of the
disorder and the best way to correct it, service personnel will
be dispatched to your location. We typically request a Purchase
Order prior to sending service personnel; however we will pro-
ceed on verbal orders in an emergency.
Once a full evaluation of the equipment has been performed
by our service personnel, you will be advised if the service
work is covered by the Spencer warranty. For out-of-warranty
services, please note that we accept Visa and MasterCard
charges as well as other forms of payment.
NOTE: Spencer products returned to the factory must be sent
freight prepaid and accompanied by a Return Service Order
(RSO) issued by the Spencer Service Department after we
receive your Purchase Order. Service costs will be quoted after
inspection and the work will be performed upon written accep-
tance of the quotation.
Material Safety Data Sheets
Spencer is committed to ensuring the safety of its employees. If
Spencer equipment has been exposed to potentially hazardous
contaminants or if Spencer service personnel could be exposed
to a potentially hazardous field environment, a Material Safety

service personnel or (b) before receipt of any equipment for fac-
tory service. If special precautions are necessary to work on the

SYSTEM Indication: low pressure/vacuum or volume as determined by gage measurement or process
• Incorrect rotation.
• Air or gas lines too small, causing
excessive friction loss.
• Valves in line not fully open or check
valve improperly installed.
• Inlet, discharge or piping system
partially blocked.
• High inlet temperature.
• Low inlet pressure.
• Machine not running at design speed.
• Low gas density or specific gravity.
• Machine air passages clogged.
• Impellers damaged by explosion, abra-
sion or vibration.
• Pressure or vacuum gage inaccurate.
Change motor leads to correct rotation.
Increase line sizes or install machine with higher output
pressure.
Open valves or inspect check valve.
Remove obstructions, clean filter.
Position inlet in a cooler area.
Check inlet for obstructions or install machine with higher dis-
charge pressure.
Refer to motor manufacturer’s instructions; check motor
speed; check voltage connections.

Calibrate gage; always use a “U” tube manometer for checking
pressure and/or vacuum.
• System requirements incorrectly
calculated by customer.
• System leaks or too many openings.
Install larger volume or lower pressure machine to handle sys-
tem requirements.
Locate and repair leaks, reduce number of openings.
Indication: measuring gas or air flow incorrectly
• Flowmeters calibrated incorrectly.
• No means of measurement available.
Calibrate flowmeters; use proper orifice for meter (check with
flowmeter manufacturer).
Obtain and install flowmeter.
